2 Centralized and Distributed Configuration of a Programmable Controller This chapter contains an overview of the methods of configuring an S5-135U/155U PLC. You will find a description of the types of communication between a central controller and the expansion units, and an overview of the interface modules required for the different types of communication. Chapter Overview System Manual C79000-G8576-C199-06 Section Contents Page 2.1 Application 2-2 2.
Centralized and Distributed Configuration of a Programmable Controller 2.1 Application The S5-135U/155U programmable controllers comprise a central controller (CC) and, if required, one or more expansion units (EUs). You need EUs when there are insufficient slots in the CC for the modules to be used. Various interface modules (IMs) are available for communication between the CC and the EUs and between the EUs.

3 Installation Guidelines The Installation Guidelines provide you with information for the interference-free installation of the SIMATIC S5-135U/155U programmable controllers.
Installation Guidelines 3.1 Principles of Installation of Systems for EMC What Does EMC Mean? Electromagnetic compatibility (EMC) is understood to mean the capability of electrical equipment to operate correctly in a defined electromagnetic environment, without being affected by the environment and without affecting the environment to an unacceptable degree. All SIMATIC S5 products have been developed for applications in harsh industrial environments and meet high requirements for EMC.
Installation Guidelines Depending on the propagation medium (conducted or non-conducted interference) and distance from the source, interference can be picked up by the programmable controller via different coupling mechanisms.
Installation Guidelines Coupling Mechanisms and Typical Interference Sources at a Glance Shown in the following table are the four different coupling mechanisms, their causes, and possible interference sources.
Installation Guidelines Coupling Mechanism Radiated Interference Interference Cause There is a radiation path when a conductor d iis subjected bj d to an electromagnetic wave. Impinging of the wave results in induced currents and voltages. Typical Interference Sources Local transmitters ( (e.g.
Installation Guidelines 3.1.2 The Most Important Basic Rules for Ensuring EMC It is often sufficient to comply with a few elementary rules for ensuring EMC. When installing the control system, therefore, observe the following five basic rules. When installing the programmable controllers, provide large-area good quality grounding of the inactive metal parts (see Section 3.2). Make a large-area low-impedance interconnection of all inactive metal parts.
Installation Guidelines Employ special EMC measures for particular applications (see Section 3.3.4). Fit quenching elements to all inductances which are not controlled by SIMATIC S5 modules. Use incandescent bulbs for illuminating cabinets, and avoid fluorescent lamps. Create a standard reference potential; ground all electrical apparatus if possible (see Sections 3.4 and 3.5). Use specific grounding measures. Grounding of the control system is a protective and functional measure.
Installation Guidelines 3.2 Installation of Programmable Controllers for EMC Measures for suppressing interference voltages are often applied only when the control system is already operational and proper reception of a useful signal is impaired. The reason for such interference is usually inadequate reference potentials caused by mistakes in equipment assembly.
Installation Guidelines 3.2.2 Example of Cabinet Assembly for EMC The example of cabinet assembly in the figure shows the various measures, the grounding of inactive metal parts and the connection of shielded cables. This example applies only to grounded operation. Follow the points numbered in the figure during assembly.
Installation Guidelines À Á Â Ã Ä Å Æ Ç 3-10 Grounding strips If there are no large-area metal-to-metal connections, you must connect inactive metal parts such as cabinet doors and supports with grounding strips. These should be short and have a large surface. Cabinet members The cabinet members should have a large-area connection to the cabinet housing (metal-to-metal connection).
Installation Guidelines 3.2.3 Example of Rack and Wall Mounting for EMC To operate your control system in a low-interference environment whilst observing the permissible ambient conditions (see “Technical Specifications”), you can mount the programmable controllers on racks or directly on walls. Picked-up interference should be given a path to large metal surfaces. You should therefore secure standard sectional rails, shield and protective conductor bars to metal structural elements.
Installation Guidelines 3.3 Wiring of Programmable Controllers for EMC The following section describes: Routing of cables within and outside cabinets Equipotential bonding between devices Single and double-ended connection of cable shields Checklist for electromagnetically compatible installation 3.3.1 Routing of Cables This section covers the routing of bus, signal and supply lines. The purpose cable routing is to suppress crosstalk between cables laid in parallel.
Installation Guidelines Legend for the table Lines can be laid in common bundles or cable ducts. Routing of Cables Outside Buildings Lines must be laid in separate bundles or cable ducts (without minimum clearance). Lines within cabinets must be laid in separate bundles or cable ducts; outside the cabinets but within buildings, they must be laid over separate cable routes with a clearance of at least 10 cm.
Installation Guidelines 3.3.2 Equipotential Bonding Between separate sections of an installation, potential differences can develop if S programmable controllers and I/O devices are connected via a non-floating link, or S cable shields are connected at both ends and are grounded at different parts of the system. Different AC supplies, for example, can cause potential differences.
Installation Guidelines 3.3.3 Shielding of Cables and Lines Shielding is a method of attenuating magnetic, electrical or electro-magnetic interference fields. Interference currents on cable shields are given a path to ground via the shield bar which is electrically connected to the housing. A low-impedance connection to the protective conductor is particularly important so that these interference currents themselves do not become an interference source.
Installation Guidelines Please observe the following points when connecting the shield: Use metal cable clamps for securing the braided shield. The clamps must enclose the shield over a large area and provide a good contact. Connect the shield to a shield bar immediately after the cable entry into the cabinet. Route the shield as far as the module but do not connect it there again.
Installation Guidelines 3.3.4 Special Measures for Interference-Free Operation Fitting Quenching Elements to Inductances As a rule, inductances such as contactor or relay coils controlled by SIMATIC S5 do not require external quenching elements in the circuit, because the quenching elements are already integrated in the modules. Inductances should only be fitted with quenching elements when SIMATIC S5 output currents can be switched off by additionally fitted contacts, such as relay contacts.
Installation Guidelines AC Power Connection for Programmers A power socket should be fitted in each cabinet for the AC supply to programmers. The sockets should be powered from the distribution system to which the protective conductor for the cabinet is also connected. Cabinet Lighting Use incandescent bulbs, such as LINESTRA lamps, for cabinet lighting. Avoid using fluorescent lamps because they generate interference fields.
Installation Guidelines 3.3.5 Checklist for the Electromagnetically Compatible Installation of Control Systems EMC Measures Connection of inactive parts Notes (Section 3.
Installation Guidelines 3.4 Power Supplies for Programmable Controllers and I/Os This section describes: Which circuits you must distinguish in the control system and which demands are made on the power supply. Connection and grounding concept with higher-level infeed from grounded, centrally grounded and ungrounded supplies. Connecting the power supply to non-isolated and isolated modules. 3.4.
Installation Guidelines Ratings of Load Power Supplies The electronic short-circuit protection of digital output modules only responds when 3-times the rated current is exceeded. You should therefore so design the load power supply units that the unit can supply the current required for shutting down in the event of a short-circuit at one output.
Installation Guidelines Load Power Supply For 24 V DC load circuits, you require a load power supply unit with safety separation. If an AC plug is used as the isolating device, the socket must be in the vicinity of the central controller and easily accessible (VDE 0805, 1.7.2). Unregulated load power supply units require a reservoir capacitor (rated at 200 mF per 1 A load current). Connect the capacitor in parallel with the output terminals of the load power supply.
Installation Guidelines Operating a Programmable Controller with Process I/Os from a Grounded Supply L1 L2 L3 N PE Operation from grounded power supplies offers the best rejection of interference. Low-Voltage Distribution e.g.
Installation Guidelines Operating a Programmable Controller with Process I/Os from a Centrally Grounded Supply In systems with their own transformers or generators, the PLC is connected to the central ground. A detachable connection should be provided so that ground faults can be measured. The PLC should be insulated from cabinet/protective conductor potential. To maintain this isolated arrangement, all connected devices must be operated with capacitive grounding or ungrounded.
Installation Guidelines Operating a Programmable Controller with Process I/Os from an Ungrounded Supply L1 L2 L3 PE In cases in which the higher-level power supply is not grounded, you must connect the programmable controller to a separate protective conductor/ground (e.g. foundation ground). Operation of the PLC with non-floating power supplies is not allowed. When connecting the power supplies, please note: In 3 x 230 V systems, you may connect the power supply directly to two phases.
Installation Guidelines 3.4.3 Connecting Non-Floating or Floating Modules Shown in the following sections are the specical features when installing non-floating and floating modules. Installation with Non-Floating Modules In an installation with non-floating modules, the reference potentials of the control circuit (0 Vint) and load circuits (0 Vext) are electrically connected.
Installation Guidelines Note For 24 V DC digital output modules with electronic short-circuit protection, you must ensure that the reference potential of the load power supply is connected to terminal L- of the module. If this connection is missing (e.g. open-circuit), a typical current of 15 mA can flow at the outputs. This output circuit is sufficient to prevent energized contactors or relays from being released and to energize high-resistance loads (e.g. miniature relays).
Installation Guidelines 3.5 Interference-Free Installation of Centralized and Distributed Interface Circuits Subjects described in the following sections are the shielding and grounding concept with centralized and distributed interface circuits. Information on component selection, the mechanical arrangement and wiring can be found in the appropriate reference manuals for the interface modules.
Installation Guidelines With distributed interfacing (IM 304/IM 314 and IM 301/IM 310), ensure that the VDE specifications for laying the protective ground are complied with; distributed interfacing is non-floating. The measures described above are shown in the following figure. If the permissible potential difference between ground points can be exceeded, you must install an equipotential bonding conductor (cross-section w 16 mm2 of copper).
Installation Guidelines 3.6 Interference-Free Connection of Monitors These sections cover the following topics: Floating connection of cables at video inputs Shielding and grounding concept Information on selecting the components can be found in Catalog ST80. 3.6.1 Interference-Free Connection of a Monitor to the CP of the S5 Controller Operator control and process monitoring systems from the COROS product family can be used with monitor connections.
Installation Guidelines In these cases, double-shielded coaxial cables (triaxial cables) must be used to transmit the video signals. The inner braided shield of the coaxial cable serves as the return conductor and must not be connected to the shield bar. The outer braided shield provides a path to ground for interference currents and must be incorporated in the shielding and grounding measures. To avoid ground loops, the electronics ground and housing ground of the monitor must be independent.
Installation Guidelines Shown in the following figure is a simplified representation of the shielding and grounding measures for installing the monitor and PLC.
Installation Guidelines 3.
Installation Guidelines 3.7.1 Types of Cabinet The following table provides on overview of the most common types of cabinet. It also shows the principle of heat removal, as well as the estimated, maximum achievable power loss removal and the type of protection* .

A maximum clearance of 400 mm is possible (50 mm min.) when devices are connected next to one another. 75 mm min.
Installation Guidelines Where subracks (CC and EU) are arranged one above the other, the installation clearances in the following table must be observed. Upper Subrack Lower Subrack S5-135U/ 155U or S5-115U or S5-90U/ 95U/ 100U S5-135U Min. Clearances 75 mm 87 mm if baffle is used S5-115U with fan 60 mm S5-115U without fan 100 mm S5-90U/ 95U/ 100U 75 mm Max. Clearances The maximum clearance is limited by the lengths of connecting g cables for the h interface i f modules.
Installation Guidelines 3.7.3 Removal of Power Dissipation from Cabinets The power dissipation that can be removed from a cabinet is governed by the cabinet design, its ambient temperature and the arrangement of equipment in the cabinet. Shown in the following figure is a diagram with guide values for the permissible ambient temperature of a cabinet measuring 600 x 600 x 2200 mm, as a function of power dissipation.
Installation Guidelines ! 3.7.4 Caution Modules with a hard disk drive can only be used at an ambient temperature of up to 50 °C. Examples for Determining the Type of Cabinet The following example shows the maximum permissible ambient temperature with various cabinet types and the same power dissipation.
Installation Guidelines 3.7.5 Determining the Power Dissipation of Modules The power dissipation of the modules can be found in the technical specifications of the catalogs or manuals. If these values are not yet incorporated in the technical specifications, they can be easily calculated from the current consumption. The value of current consumption must be multiplied by the corresponding voltage value. Examples CPU 928B Current consumption 5A/5V CP 143 Current consumption 4A/5V 0.5A/15V 0.

Multiprocessor Operation/Coordinators 6 This chapter explains how to install multiprocessor operation in the S5-135U/155U programmable controller and start operations. You will require the 923A or 923C coordinator module. The technical functions of these modules are described. Chapter Overview System Manual C79000-G8576-C199-06 Section Description Page 6.1 Introduction 6-2 6.2 Starting the Multiprocessor Operation 6-3 6.3 Coordinator Modes 6-13 6.4 923A Coordinator Module 6-15 6.
Multiprocessor Operation/Coordinators 6.1 Introduction The S5-135U/155U is a member of the SIMATIC S5 family of programmable (logic) controllers. The PLC can be used both in single and in multiprocessor operation with up to four CPUs. Slots Occupied You can arbitrarily combine the CPUs in the central controller at the CPU slots.
Multiprocessor Operation/Coordinators 6.2 Starting the Multiprocessor Operation This section guides you through the installation and startup of multiprocessor operation; the following is assumed: You are familiar with the use and programming of individual modules in single-processor operation. If this is not the case, please consult the relevant chapters in this manual and in the appropriate Programming Guides.
Multiprocessor Operation/Coordinators Setting the Jumpers Shown in Figures 6-1 and 6-2 are the locations of jumpers and switches on the modules, at which the settings required for startup must be made. Note The settings of jumpers which are not described in the following text must not be changed.

Multiprocessor Operation/Coordinators Step 4 Action Switch the supply voltage on. Reaction 1. The red STOP LEDs flash rapidly on all CPUs to indicate: Overall reset requested. 2. If the test mode is not set at the coordinator (see Section 6.3) and the mode switch is not at the TEST setting: The red BASP (output inhibit) LED is permanently lit to indicate: Digital outputs are inhibited. Possible Faults Symptom: On some CPUs the STOP LED is not lit; the other CPUs are requesting OVERALL RESET.
Multiprocessor Operation/Coordinators Step 6 Loading STEP 5 user programs in all CPUs: Recommended precondition: The programs of the individual CPUs have already been tested in single-processor operation. For details of loading STEP 5 blocks and using the different types of memory, please consult the relevant Programming Guides of the CPUs and your PG Manual. Prerequisites What? Where? Data block DB 1 must be present for I/O allocation.
Multiprocessor Operation/Coordinators Step 7 Executing a RESET at all CPUs: Action Reaction Execute a RESET at each individual CPU: Hold the MC 1) mode switch at the RESET setting; simultaneously set the mode switch from STOP to RUN. The red STOP LED on each CPU is continuously lit; each CPU emits the output inhibit signal. The CPUs are in the wait state. 1) Possible Faults MC: Momentary-contact Symptom 1: The STOP LED of one CPU flashes slowly.
Multiprocessor Operation/Coordinators Step 8 Setting the coordinator mode switch to RUN or TEST: IF ... Reaction You do not wish to Set the coordinator work in the test mode 1) mode switch from STOP to RUN. The green RUN LEDs of all CPUs are continuously lit. All CPUs simultaneously go into the cycle. The output inhibit signal is not emitted (BASP LED = off). You wish to work in the Set the coordinator test mode (it must be mode switch from enabled on the STOP to TEST.
Multiprocessor Operation/Coordinators 6.3 Coordinator Modes The Stop State If, when the supply voltage is switched on, the coordinator mode switch is at STOP or another stop request is pending, the CPUs remain in the Stop state.
Multiprocessor Operation/Coordinators Test Mode ! Warning Since, in the test mode, no CPU can emit a BASP (output inhibit) in the event of a fault, the test mode must be switched to the inactive state without fail after completion of startup to avoid a critical or even hazardous system state. Before you can go into the test mode with the TEST switch, you have to enable it on the module. This is achieved differently with the 923A and 923C coordinators.
Multiprocessor Operation/Coordinators 6.4 6.4.1 923A Coordinator Module Technical Description This section contains information on the application, design and principle of operation of the 923A coordinator. Application The 923A coordinator module is intended for operation in the S5-135U/155U PLC. It is required in multiprocessor operation and has the following functions: Bus arbitration To coordinate multiprocessor operation, i.e.
Multiprocessor Operation/Coordinators Principle of Operation Bus arbitration The COR 923A cyclically allocates a bus enable signal to each of the two to four CPUs in the S5-135U/155U PLC. Only during this time can the relevant CPU utilize the common S5 bus. The assignment of bus enable signals takes place in time-division multiplex operation. On the COR 923A, you set the number of CPUs with jumpers. The enable time for access to the S5 bus is preset at 2 ms for all CPUs.
Multiprocessor Operation/Coordinators Please consult the Programming Guides of the CPUs to program these functions. 6.4.2 Settings on the Coordinator User Control A three-stage mode switch on the front plate serves for user control; it has the settings RUN, STOP and TEST. The functions of the mode switch and its use are explained in Sections 6.2 and 6.3.
Multiprocessor Operation/Coordinators 6.5 6.5.1 923C Coordinator Module Technical Description This section contains information on the application, design and principle of operation of the 923C coordinator. Application The 923C coordinator module can be used in the S5-135U/155U programmable controller and in the EU S5-185U expansion unit. There are three main task areas which are, to some extent, independent: Bus arbitration (only in the central controller) To coordinate multiprocessor operation, i.e.
Multiprocessor Operation/Coordinators Design The COR 923C is designed as a plug-in PCB in double Eurocard format. Two 48-way Series 2 blade connectors serve to connect the module to the S5 bus in the subrack. The front plate width is 1 1/3 standard plug-in stations. A mode switch with three settings is fitted in the front plate for other operator functions. Faults are indicated by five small red LEDs. There is a recess with cover in the upper third of the front plate.
Multiprocessor Operation/Coordinators Bus Enable for: CPU1 2µs CPU2 CPU3 2µs + Bus Lock CPU4 Bus Lock Reset CPUs in Operation Time Figure 6-7 Timing Sequences of the Bus Control Signals Monitoring for continuous bus assignment The bus lock signal can only be emitted by the CPU which has already received a bus enable signal from the COR 923C. The bus enable time is extended by the duration of the bus lock signal for the CPU (see Figure 6-7).

8 Digital Input/Output Modules Described in this chapter are the installation, wiring and operation of digital input modules and digital output modules. The 432 digital input module and the 482 digital input/output module have special features. These are discussed in separate sections. The technical specifications and front connector assignments for the individual modules are shown at the end of this chapter. Chapter Overview System Manual C79000-G8576-C199-06 Section Description Page 8.
Digital Input/Output Modules 8.1 Technical Description The description below applies to the following modules: Type of Modules Inputs/Outputs Input/Output C Current t Isolation/ Groups *) Number Rated Voltage 32 32 16 32 32 16 16 8 24 V DC 24 V DC 24 to 60 V DC 24 V DC/alarm 5 to 15 V DC 24 to 60 V AC 115 to 230 V AC 115 to 230 V AC 8.5 mA 7.0 mA 4.5 to 7.5 mA 8.5 mA 1.
Digital Input/Output Modules Digital Input Modules A digital input module converts the process signals to the internal signal level in the module. Interference is suppressed by the input circuitry, and the logic states at the inputs are indicated with LEDs on the front strip of the module. With most digital input modules (except the 420), the signals are isolated from the central ground point when received.
Digital Input/Output Modules 8.1.1 Design The modules are designed as plug-in PCBs for central controllers and expansion units with backplane connector and with a blade connector to accept a plug-in front connector. The front connector has screw or crimp terminals and is available separately; you can connect the process signal lines to it directly. LED Indicators Fitted to each module is a strip with green LEDs to indicate the logic states of inputs or outputs.
Digital Input/Output Modules 8.1.2 Function of the Enable Inputs The digital input/output modules have an enable circuit. You can use the enable inputs to implement electrical interlocks for certain modules or switch off individual modules, whilst the PLC is in operation. This means that: The module can no longer be addressed by the user program. All outputs of digital output modules are set to zero. Modules which are switched off can be removed or inserted during operation.
Digital Input/Output Modules Jumper inserted: Jumper open: Enable input (F+/F-) active (factory setting) Enable input (F+/F-) switched off With Enable Input Switched Off If removal and insertion of modules during operation is not required, you must remove the plug-in jumper for changeover of the enable mode. Wiring of the enable inputs (F+/F-) can then be dispensed with. Examples of Functioning of the Enable Inputs Almost power-free shutdown of individual subprocesses, i.e.
Digital Input/Output Modules Separate or Common Shutdown of the CC/EU and Load Power Supply When there is a need to switch off the load power supply separately without affecting the enabling of modules, there are the following possibilities for producing the enable voltage. These exist even when the power supply is used without an additional capacitor and common shutdown.
Digital Input/Output Modules 8.1.3 Special Features of the 432 Digital Input Module The 432 digital input module accepts 32 process signals and emits a process alarm if the logic state at one of its inputs changes.
Digital Input/Output Modules Operation with Process Alarm via Interrupt To operate the 432 digital input module with process alarm via an interrupt, you must either operate it in the CC where only certain slots have interrupt lines (see Chapter 4), or in an interrupt-capable EU connected to the CC with IM 307 - IM 317 interfacing (see also the IM 307 - IM 317 manual). In the CC, you may only operate the module in this mode at slots with an interrupt line (interrupt source).

Digital Input/Output Modules Only the flag word (FW) may be accessed during the cyclic program. Accessing the I/O bytes in the process image will result in alarm loss. Addressing of the module must therefore be above address 127. Double accessing of I/O bytes, even from different CPUs, is not permissible (alarm loss). The four I/O bytes of a module must be scanned successively and in ascending order.
Digital Input/Output Modules Using Two or More 432 Digital Input Modules with Process Alarm via IB 0 You can use up to eight 432 digital input modules with process alarm via IB 0 in one PLC. The modules must all be inserted in the CC or in the same EU for error-free acknowledgement of address 0. Each module reserves one bit in IB 0. You must set one module to bit 0 on switch row S2; on the other modules you must remove jumper X3 and set one of the other bits 2 to 8.
Digital Input/Output Modules Changeover of the I/O byte The operation of Channels 1.0 to 1.7 as inputs or outputs merely depends on the user program. You define the byte as an input with a read access to the DI/DQ; you define the byte as an output with a write access. The double-function of the byte also allows the output byte to be read out. Unused channels should not be wired nor addressed by program.
Digital Input/Output Modules 8.2 Installation and Startup This section describes how to prepare digital input/output modules for installation, and how to install and wire them. 8.2.1 Setting the Module Address You set the module address on the addressing switch. This also establishes the necessary assignments between user program and process connection.

Digital Input/Output Modules The following table is an overview of settings for addressing digital input/output modules.
Digital Input/Output Modules 8.2.2 Removing and Inserting Modules ! Warning When removing and inserting the front connector during operation, hazardous voltages of more than 25 V AC or 60 V DC may be present at the module pins. When this is the case at the front connector, live modules may only be replaced by electrical specialists or trained personnel in such a way that the module pins are not touched.
Digital Input/Output Modules Remove a digital input/output module as follows: Step Action 1 Release the upper locking bar on the subrack and swivel it upwards and out. 2 Slacken the screw in the upper part of the front connector. This causes the front connector to be pressed out of the female connector of the module. Contacts F+ and F- of the enable input at the upper end of the front connector are thus opened first.
Digital Input/Output Modules 8.2.3 Marking of Modules For the marking of modules and front connectors, a set of labels is supplied with the modules for the labeling, and a set of labels with the addresses is supplied with the central controller. Figure 8-9 shows the locations of the labels. The self-adhesive address label is pre-printed. You can mark the strips to identify the signal line terminals.
Digital Input/Output Modules 8.2.4 Connecting the Signal Lines The modules have 20 or 42-way blade connectors with contact blades measuring 2.4 x 0.8 mm. Front connectors for 20 and 40 mm mounting width with crimp connection and 40 mm mounting width with screw connection are provided to connect the signal lines (screwdriver blade width: 3.5 mm, maximum torque: 0.8 Nm). Use stranded conductor to facilitate handling of the front connector.
Digital Input/Output Modules 8.2.5 Connection of Outputs in Parallel and Switching On the Load via a Contact ! Digital Output Modules for DC Voltage Caution The parallel connection of outputs to increase the load is not permissible. Outputs of modules with the same load voltage supply may be connected in parallel without additional circuitry. An external diode must be fitted to the output lines of modules fed from different load voltage supplies (exception: 453, 457).
Digital Input/Output Modules The load can also be switched via a contact.

Digital Input/Output Modules 8.2.7 Arc-Quenching for Inductive Loads Note Digital output modules have integrated circuits on the module to quench inductive loads (refer to the technical specifications of the output modules). Exception: The 458 digital output module allows the switching of inductive loads with contact protection submodules.
Digital Input/Output Modules External Quenching Circuitry External quenching circuitry is needed when the switching frequency of an output is greater than that specified in the technical specifications (thermal stress of the integrated circuit for quenching inductive loads); disconnection of output lines can be expected; disconnection of the supply line can be expected. When selecting or designing the quenching circuitry, the technical specifications for the digital output should be taken into account.
Digital Input/Output Modules Two-Wire Switches With two-wire switches and AC voltage outputs: Disconnection of the supply voltage during operation is not permissible without additional protective circuitry. Quenching of the inductive load is achieved here via the load power supply unit or system. Since, as two-wire switches, the outputs have no L-/N (0 V ground) terminal, the inductive load cannot be quenched on the module when the supply line is disconnected.

Analog Input/Output Modules 9 Described in this chapter are the installation, wiring and operation of analog input modules and analog output modules. The individual modules have special features. These are discussed in separate sections.

Analog Input/Output Modules 9.2 Common Technical Specifications Important for the USA and Canada The following approvals have been issued: UL Listing Mark Underwriters Laboratories (UL) to Standard UL 508, Report E 85972 and E116536 for the 466-7LA11 analog input module CSA Certification Mark Mark Canadian Standard Association (CSA) to Standard C 22.2 No.
Analog Input/Output Modules 9.3 9.3.1 The 460 Analog Input Module Design The modules are designed as plug-in PCBs for central controllers and expansion units with a backplane connector and with a blade connector to accept a plug-in front connector. You can directly connect the process signal lines to the front connector, which is available separately, with screw or crimp terminals.
Analog Input/Output Modules Enable Input The enable circuit requires an external 24 V voltage at enable inputs F+/F- in the front connector. If there is no voltage at F+/F-, the modules will not acknowledge. When the front connector is swivelled away from the front strip of the module, the supply of power to the enable input is interrupted, i.e. the module is switched off and can no longer be addressed by the user program: a timeout (QVZ) occurs in the CC.
Analog Input/Output Modules Configuring You must observe the following when configuring systems: Switching on At the latest 100 ms after power-up of the PLC, the voltage must be present at the enable inputs of the I/O modules. Switching off When the PLC has been switched off, the voltage at the enable inputs of the I/O modules must still be present as long as the internal 5 V voltage is present.
Analog Input/Output Modules 24 V supply for CC/EU and I/Os a) Battery b) I/O Modules F+ CC/EU L+ Power Supply 24V L+ 24 V DC Supply for the enable inputs from: a) Battery b) Terminals for 24 V on the front plate of the power supply Common Shutdown of the CC/EU and Load Power Supply with a 230 V AC Supply Proper functioning is ensured if the 24 V load power supply has an output capacitance of at least 4700 mF per 10 A of load current.
Analog Input/Output Modules 9.3.3 Special Features of the 460 Analog Input Module The 460 analog input module executes integrating processing of the digital input signals; periodic system interference is thus suppressed. You can adapt the process signals, according to the application, to the input level of the analog-to-digital converter of the module with plug-in range cards (resistor dividers or shunt resistors).
Analog Input/Output Modules Selective Sampling In the selective sampling mode, a measured value is encoded on the central initiative of the CPU. At the start of conversion, the module must be addressed once with a write operation (T PW) by the user program. An active bit (T = 1) is set during encoding. With the transition to T = 0, the measured value becomes valid. With non-constant cycle times, there may be non-periodic measured value aquisition.
Analog Input/Output Modules 9.3.4 Setting the Module Address You set the module address on the addressing switch. This also establishes the necessary assignments between user program and process connection. The module address is the sum of the decimal significances of the switch rockers in the On setting (Ĥ). One data word = two data bytes is required to process an input or an output.
Analog Input/Output Modules Note The start address of the analog module must be a multiple of the double channel number. 4 channels : 0, 8, 16, 24, ... 248 8 channels : 0, 16, 32, 48, ... 240 If one of the inputs or outputs (Channel 0 to 7) of a module is to be addressed, the relevant subaddress must be specified in the program. The subaddress of the input or output, based on the start address of the module, is given by: Start address + 2 x channel no.
Analog Input/Output Modules Addressing for Cyclic/Selective Sampling However, analog input modules and analog output modules may be given the same address with cyclic sampling because they are distinguished by the user program. This is not possible with selective sampling. For cyclic sampling, you can address the module in the address range from 0 to 255, and for selective sampling from 128 to 255.
Analog Input/Output Modules 9.3.5 Removing and Inserting Modules ! Warning When removing and inserting the front connector during operation, hazardous voltages of more than 25 V AC or 60 V DC may be present at the module pins. When this is the case at the front connector, live modules may only be replaced by electrical specialists or trained personnel in such a way that the module pins are not touched.
Analog Input/Output Modules Remove an analog input/output module as follows: Step Action 1 Release the upper locking bar on the subrack and swivel it upwards and out. 2 Slacken the screw in the upper part of the front connector. This causes the front connector to be pressed out of the female connector of the module. Contacts F+ and F- of the enable input at the upper end of the front connector are thus opened first.
Analog Input/Output Modules 9.3.6 Marking of Modules and Front Connectors For the marking of modules and front connectors, labels are supplied with the module and central controller; they are affixed as shown in Figure 9-5.
Analog Input/Output Modules 9.3.7 Connecting the Signal Lines For connection of the signal lines, front connectors for 20 and 40 mm mounting width with crimp connection and 40 mm mounting width with screw connection are available (screwdriver blade width: 3.5 mm, maximum torque: 0.8 Nm). Use stranded conductor to facilitate handling of the front connector. Ferrules are not required for screw connections, because the screw terminals are provided with wire protection.
Analog Input/Output Modules 9.3.8 Connection of Sensors Observe the following information when connecting the sensors. Connection of Current or Voltage Sensors With isolated sensors, it is possible for the measuring circuit to develop a potential with respect to ground which exceeds the permissible potential difference UCM (see maximum values of the individual modules). To prevent this, you must connect the negative potential of the sensor to the reference potential of the module (0 V bus).

Sensor, Not Isolated + – + – Analog Input Module M+ A MUX UE M– Range Card for 4 Inputs # U CM D U CM Figure 9-7 0 V Bus Measuring Circuit without Equipotential Bonding Conductor for the 460 Analog Input Module The potential of the busbar with respect to the reference potential of the module is, for example, 24 V DC.
Analog Input/Output Modules 9.3.9 Connecting a Compensating Box for Thermal E.M.F. Measurement If the room temperature fluctuations at the reference point (e.g. in the terminal box) affect the measurement result and you do not wish to use a thermostat, you can compensate for the effect of temperature on the reference point with a compensating box. Between - 10 and + 70 oC, it compensates for the change in thermal e.m.f. cause by temperature deviation (compensating box, see Catalog MP 11).
Analog Input/Output Modules 9.3.10 Connecting Resistance Thermometers in the Standard Pt 100 Range The series-connected resistance thermometers (up to 8 Pt 100s) are fed with a current of 2.5 mA (IC+/IC-) by a constant current generator. The voltage at the Pt 100’s is picked off at measurement inputs M+ and M-. In this mode, the whole temperature range of the Pt 100 (-200 °C to +840 °C) is available.
Analog Input/Output Modules 9.3.11 Connecting Resistance Thermometers in the Extended Pt 100 Range The series-connected resistance thermometers (up to 8 Pt 100s) are fed with a current of 2.5 mA (IC+/IC-) by a constant current generator. The voltage at the Pt 100s is picked off at measurement inputs M+ and M-. In this mode, the temperature range of approximately -100 °C to +100 °C has a more accurate resolution.
Analog Input/Output Modules 9.3.12 Broken Wire Signal Broken Wire Signal in the Standard Pt 100 Range An open-circuit in the lines to a resistance thermometer is indicated as follows: Broken Wire at M+ M– Pt 100 IC+ IC– 1) Module Reaction, Encoded Value 0 0 0 1) 0 0 Error Bit E 1 1 1 0 0 With the 460 analog input module, the value 0 is also encoded for the intact Pt 100 resistances because the auxiliary circuit is interrupted; the error bit will not be set for these channels.

Analog Input/Output Modules 9.4 9.4.1 The 463 Analog Input Module Design The modules are designed as plug-in PCBs for central controllers and expansion units with a backplane connector and with a blade connector to accept a plug-in front connector. You can directly connect the process signal lines to the front connector, which is available separately, with screw or crimp terminals.
Analog Input/Output Modules Enable Input The enable circuit requires an external 24 V voltage at enable inputs F+/F- in the front connector. If there is no voltage at F+/F-, the modules will not acknowledge. When the front connector is swivelled away from the front strip of the module, the supply of power to the enable input is interrupted, i.e. the module is switched off and can no longer be addressed by the user program: a timeout (QVZ) occurs in the CC.
Analog Input/Output Modules Configuring You must observe the following when configuring systems: Switching on At the latest 100 ms after power-up of the PLC, the voltage must be present at the enable inputs of the I/O modules. Switching off When the PLC has been switched off, the voltage at the enable inputs of the I/O modules must still be present as long as the internal 5 V voltage is present.

Analog Input/Output Modules 9.4.3 Special Features of the 463 Analog Input Module The 463 analog input module executes integrating processing of the digital input signals; periodic system interference is thus suppressed. Adaptation of the Measuring Range The measuring range for each channel is adapted by appropriately connecting the sensors and with jumpers in the front connector of the module (see the front connector assignments).
Analog Input/Output Modules Press the individual rockers of the addressing switch downwards with a ballpoint pen or similar object, but not a pencil.

Analog Input/Output Modules 9.4.5 Removing and Inserting Modules ! Warning When removing and inserting the front connector during operation, hazardous voltages of more than 25 V AC or 60 V DC may be present at the module pins. When this is the case at the front connector, live modules may only be replaced by electrical specialists or trained personnel in such a way that the module pins are not touched.
Analog Input/Output Modules Remove an analog input/output module as follows: Step Action 1 Release the upper locking bar on the subrack and swivel it upwards and out. 2 Slacken the screw in the upper part of the front connector. This causes the front connector to be pressed out of the female connector of the module. Contacts F+ and F- of the enable input at the upper end of the front connector are thus opened first.
Analog Input/Output Modules 9.4.6 Marking of Modules and Front Connectors For the marking of modules and front connectors, labels are supplied with the module and central controller; they are affixed as shown in Figure 9-16.
Analog Input/Output Modules 9.4.7 Connecting the Signal Lines For connection of the signal lines, front connectors for 20 and 40 mm mounting width with crimp connection and 40 mm mounting width with screw connection are available (screwdriver blade width: 3.5 mm, maximum torque: 0.8 Nm). Use stranded conductor to facilitate handling of the front connector. Ferrules are not required for screw connections, because the screw terminals are provided with wire protection.

Analog Input/Output Modules 9.5.3 Special Features of the 465 Analog Input Module The 465 analog input module executes integrating processing of the digital input signals; periodic system interference is thus suppressed. You can adapt the process signals, according to the application, to the input level of the analog-to-digital converter of the module with plug-in range cards (resistor dividers or shunt resistors).
Analog Input/Output Modules In the selective sampling mode, a measured value is encoded on the central initiative of the CPU. At the start of conversion, the module must be addressed once with a write operation (T PW) by the user program. An active bit (T = 1) is set during encoding. With the transition to T = 0, the measured value becomes valid. With non-constant cycle times, there may be non-periodic measured value aquisition.
Analog Input/Output Modules 9.5.4 Setting the Module Address You set the module address on the addressing switch. This also establishes the necessary assignments between user program and process connection. The module address is the sum of the decimal significances of the switch rockers in the On setting (Ĥ). One data word = two data bytes is required to process an input. A module with 8 inputs therefore reserves 16 byte addresses, and a module with 16 inputs or outputs reserves 32 byte addresses.
Analog Input/Output Modules Note The start address of the analog module must be a multiple of the double channel number. 8 channels : 0, 16, 32, 48, ... 240 16 channels : 0, 32, 64, 96, ... 224 If one of the inputs or outputs (Channel 0 to 7 or 0 to 15) of a module is to be addressed, the relevant subaddress must be specified in the program. The subaddress of the input or output, based on the start address of the module, is given by: Start address + 2 x channel no.
Analog Input/Output Modules Addressing for Cyclic/Selective Sampling However, analog input modules and analog output modules may be given the same address with cyclic sampling because they are distinguished by the user program. This is not possible with selective sampling. For cyclic sampling, you can address the module in the address range from 0 to 255, and for selective sampling from 128 to 255.

Analog Input/Output Modules 9.5.7 Connecting the Signal Lines For connection of the signal lines, front connectors for 20 and 40 mm mounting width with crimp connection and 40 mm mounting width with screw connection are available (screwdriver blade width: 3.5 mm, maximum torque: 0.8 Nm). Use stranded conductor to facilitate handling of the front connector. Ferrules are not required for screw connections, because the screw terminals are provided with wire protection.
Analog Input/Output Modules 9.5.8 Connecting a Compensating Box for Thermal E.M.F. Measurement If the room temperature fluctuations at the reference point (e.g. in the terminal box) affect the measurement result and you do not wish to use a thermostat, you can compensate for the effect of temperature on the reference point with a compensating box. Between - 10 and + 70 oC, it compensates for the change in thermal e.m.f. cause by temperature deviation (compensating box, see Catalog MP 11).
Analog Input/Output Modules 9.5.9 Connecting Resistance Thermometers to the 465 Analog Input Module The relevant resistance thermometer is fed with a current of 2.5 mA (IC+/IC-) by a constant current generator via a 6ES5 498-1AA11 card. The voltage at the Pt 100 is picked off at measurement inputs M+ and M-. If only inputs 0 to 3 are assigned to resistance thermometers, you can connect other current and voltage sensors to inputs 4 to 7 by means of a coding key.

Analog Input/Output Modules Setting the Type of Measurement Measurement with respect to ground/differential measurement The type of measurement (with respect to ground or differential measurement) is set with switch S9.

Analog Input/Output Modules 9.6.4 Removing and Inserting Modules ! Warning When removing and inserting the front connector during operation, hazardous voltages of more than 25 V AC or 60 V DC may be present at the module pins. When this is the case at the front connector, live modules may only be replaced by electrical specialists or trained personnel in such a way that the module pins are not touched.
Analog Input/Output Modules Remove an analog input/output module as follows: Step Action 1 Release the upper locking bar on the subrack and swivel it upwards and out. 2 Slacken the screw in the upper part of the front connector. This causes the front connector to be pressed out of the female connector of the module. Contacts F+ and F- of the enable input at the upper end of the front connector are thus opened first.
Analog Input/Output Modules 9.6.5 Marking of Modules and Front Connectors For the marking of modules and front connectors, labels are supplied with the module and central controller; they are affixed as shown in Figure 9-29.
Analog Input/Output Modules 9.6.6 Connecting the Signal Lines For connection of the signal lines, front connectors for 20 and 40 mm mounting width with crimp connection and 40 mm mounting width with screw connection are available (screwdriver blade width: 3.5 mm, maximum torque: 0.8 Nm). Use stranded conductor to facilitate handling of the front connector. Ferrules are not required for screw connections, because the screw terminals are provided with wire protection.
Analog Input/Output Modules 9.6.7 Connecting Sensors to the 466 Analog Input Module The connections for the 466 analog input module depend on the type of measurement (with respect to ground or differential measurement). Measurement with Respect to Ground For measurement with respect to ground, all signal lines have a common reference point. This is achieved by connecting all the M inputs in use to one point.
Analog Input/Output Modules The following figure shows the connection of sensors to the module. For measurement with respect to ground, all the M- connection points are interconnected internally on the module.
Analog Input/Output Modules The channels have the following designations on the module: Channel 0: Channel 1: : Channel 7: M0 + M0 – M1 + M1 – : M7 + M7 – Channels are arranged in groups of four, for which you can set separate measuring ranges: Channel group I: Channel group II: Channels 0 to 3 Channels 4 to 7 The following figure shows the connection of sensors to the module. You must observe the following condition: UE + UCM < 12 V (i.e.

Analog Input/Output Modules 9.7 9.7.1 The 470 Analog Output Module Design The module is designed as a plug-in PCB for central controllers and expansion units with a backplane connector and with a blade connector to accept a plug-in front connector. You can directly connect the process signal lines to the front connector, which is available separately, with screw or crimp terminals.
Analog Input/Output Modules Enable Input The enable circuit requires an external 24 V voltage at enable inputs F+/F- in the front connector. If there is no voltage at F+/F-, the modules will not acknowledge. When the front connector is swivelled away from the front strip of the module, the supply of power to the enable input is interrupted, i.e. the module is switched off and can no longer be addressed by the user program: a timeout (QVZ) occurs in the CC.
Analog Input/Output Modules Configuring You must observe the following when configuring systems: Switching on At the latest 100 ms after power-up of the PLC, the voltage must be present at the enable inputs of the I/O modules. Switching off When the PLC has been switched off, the voltage at the enable inputs of the I/O modules must still be present as long as the internal 5 V voltage is present.
Analog Input/Output Modules 24 V supply for CC/EU and I/Os a) I/O Modules Battery b) F+ CC/EU L+ Power Supply 24V L+ 24 V DC Supply for the enable inputs from: a) Battery b) Terminals for 24 V on the front plate of the power supply Common Shutdown of the CC/EU and Load Power Supply with a 230 V AC Supply Proper functioning is ensured if the 24 V load power supply has an output capacitance of at least 4700 mF per 10 A of load current.
Analog Input/Output Modules 9.7.3 Special Features of the 470 Analog Output Module BASP (Output Inhibit) The BASP signal is not interpreted by the 470 analog output module. Once output, a value is retained. Function Block You can output analog values to the process via analog output modules with a function block from the “basic functions” package. 9.7.4 Setting the Module Address You set the module address on the addressing switch.
Analog Input/Output Modules Start Address, Subaddress For analog output modules ( 8 outputs) only the lowest address (start address) is set. Other addresses (subaddresses) are decoded on the module. Note The start address of an analog module must be a multiple of the double channel number. 8 channels : 0, 16, 32, 48, ... 240 If one of the outputs (Channel 0 to 7) of a module is to be addressed, the relevant subaddress must be specified in the program.
Analog Input/Output Modules Addressing for Cyclic/Selective Sampling However, analog input modules and analog output modules may be given the same address with cyclic sampling because they are distinguished by the user program. This is not possible with selective sampling. For cyclic sampling, you can address the module in the address range from 0 to 255, and for selective sampling from 128 to 255.

Warning When removing and inserting the front connector during operation, hazardous voltages of more than 25 V AC or 60 V DC may be present at the module pins. When this is the case at the front connector, live modules may only be replaced by electrical specialists or trained personnel in such a way that the module pins are not touched.

Analog Input/Output Modules 9.7.7 Connecting the Signal Lines For connection of the signal lines, front connectors for 20 and 40 mm mounting width with crimp connection and 40 mm mounting width with screw connection are available (screwdriver blade width: 3.5 mm, maximum torque: 0.8 Nm). Use stranded conductor to facilitate handling of the front connector. Ferrules are not required for screw connections, because the screw terminals are provided with wire protection.
Analog Input/Output Modules 9.7.8 Connecting Loads to the 470 Analog Output Module The voltage at the load is measured at a high resistance via the sensor lines (S+/S-) of voltage output QV, so that voltage drops on the load lines do not falsify the load voltages. Lines S+(x) and S-(x) should therefore be directly connected to the load (four-wire circuit). The voltage drops on the lines from QV(x) to the load and from the load to MANA must not exceed 3 V.
Analog Input/Output Modules If, with voltage outputs, an excessively great voltage drop must be expected on the lines to the load, you must route the sensor lines S+(x) and S-(x) to the load. When voltage outputs are not used, the S+(x) sensor lines in the front connector must be connected to the corresponding voltage output terminals (QV(x)) with wire jumpers. The S-(x) sensor lines must be connected to MANA with wire jumpers. You must also insert the same jumpers if only current outputs are used.

Monitoring Module 10.1 Application The monitoring module can be used in the expansion units of the programmable controllers S5-115U, S5-135U and S5-155U. The module monitors the data bus, the address bus and the control signals MEMW/, MEMR/ and RDY/. Faults are displayed via four red LEDs on the front panel. A group signal is output at the same time via a floating contact. Following a fault, the module can be reset by means of the RESET key on the front panel or the RESET input (see Section 10.2.3). 10.1.
Monitoring Module 10.1.2 Mode of Operation 10.1.
Monitoring Module 10.1.4 Fault Detection From an address which has been set at switch S1, the data (55H or AAH) is read by the CPU from the monitoring module. This data is to be written back by the CPU to the address set at switch S2. The module inverts the accurate incoming data bit by bit (from 55H to AAH or vice versa) which is read again in the next cycle from the address set at S1.
Monitoring Module Control Line Faults A control line fault (R/W) occurs if – the write signal (MEMW/) and the read signal (MEMR/) are active simultaneously, – the acknowledgement signal (RDY/) is active without a (MEMW/) or (MEMR/) signal and – the address line ’peripheral memory’ (PESP’) has not changed from status “1” to “0.” Evaluation of the control signal (PESP’) can be turned off with the S5/7 switch. If the module is used in a programmable controller into which only I/O modules may be inserted (i.

Monitoring Module 10.3 Operation Switch S1 (Read) and S2 (Write) The addresses set at these switches are acknowledged by the monitoring module with RDY/ and are therefore not to be used again for inputs and outputs in this programmable controller (double addressing is not allowed). Switch S3 (Listen) and S4 (Listen) No acknowledgement signal (RDY/) is returned by the monitoring module to the addresses set the switches S3 and S4.

Guidelines for Handling Electrostatically-Sensitive Devices (ESD) B.1 What is ESD? Definition All electronic modules are equipped with large-scale integrated ICs or components. Due to their design, these electronic elements are very sensitive to overvoltages and thus to any electrostatic discharge. These Electrostatically- Sensitive Devices are commonly referred to by the abbreviation ESD.
Guidelines for Handling Electrostatically-Sensitive Devices (ESD) B.2 Electrostatic Charging of Persons Charging Every person with a non-conductive connection to the electrical potential of its surroundings can be charged electrostatically. Figure B-1 shows you the maximum values for electrostatic voltages which can build up on a person coming into contact with the materials indicated in the figure. These values are in conformity with the specifications of IEC 801-2.
Guidelines for Handling Electrostatically-Sensitive Devices (ESD) B.3 General Protective Measures Against Electrostatic Discharge Damage Ensure Sufficient Grounding Make sure that the personnel, working surfaces, and packaging are sufficiently grounded when handling electrostatically-sensitive devices. You thus avoid electrostatic charging. Avoid Direct Contact You should touch electrostatically-sensitive devices only if it is unavoidable (for example, during maintenance work).
