IGWiPS200-1 • For devices with explosion protection: training, instruction or authorization to work on electrical circuits for systems that could cause explosions. • Training or instruction according to the safety standards in the care and use of suitable safety equipment. SCOPE This manual does not purport to cover all details or variations in equipment or to provide for every possible contingency to be met in connection with installation, operation, or maintenance.
IGWiPS200-1 INTRODUCTION This publication describes installation of the Siemens Wireless Process Solution (WiPS) 200 Series Two-Way Multipoint-To-Point Radios and I/O Expansion Modules. Radios (i.e. transceivers) 1 and I/O modules are used to construct a WiPS wireless network for the gathering and distribution of process related analog, digital, and pulse/frequency data. Table 1, on the next page, identifies each WiPS 200 Series model.
IGWiPS200-1 Each transceiver and each I/O Expansion module has bus connectors on both sides of its cover: a male connector on one side, a female connector on the other. A transceiver and several I/O Expansion modules can be physically interconnected by way of their bus connectors and then snapped onto a section of DIN rail as a single unit. These bus connectors carry signal, power, and ground connections between the interconnected devices.
IGWiPS200-1 PRODUCT SUPPORT When contacting Siemens for support: • • Please have complete product information at hand: • For hardware, this information is provided on the product nameplate (part number or model number, serial number, and/or version). • For most software, this information is given in the Help > About screen.
IGWiPS200-1 INSTALLATION This section provides installation procedures for a WiPS 200 Series wireless network. A wireless network contains a master transceiver and up to eight remote (i.e. slave) transceivers. I/O Expansion modules provide the network with additional analog, digital, and pulse I/O capacity. Transceivers and I/O modules are mounted on user-supplied DIN rail by the installer.
IGWiPS200-1 DANGER Electrical shock hazard Explosion hazard Will cause death or injury. • Remove power from all wires and terminals before working on equipment. • In a potentially hazardous atmosphere, remove power from equipment before connecting or disconnecting power, signal, or other circuit. • Observe all pertinent regulation regarding installation in hazardous area. Matched Transceivers When WiPS transceivers (see Table 1) are ordered, a master transceiver and up to eight matched remote (i.e.
IGWiPS200-1 Changes or modifications not expressly approved by Siemens will void the user’s authority to operate the equipment. This product is intended for fixed installation applications. In order to comply with FCC/ISC adopted RF exposure requirements, installation of this transmitter system’s antenna must be performed in a manner that will provide at least a six foot (2m) clearance from the front radiating aperture to any user or member of the public. FCC ISC UL 47CFR15.247 RSS 210 Class I, Div.
IGWiPS200-1 ANTENNA CONNECTORS AND SURGE VOLTAGE PROTECTION Each transceiver has an MCX female antenna connector. The base 3-1/2", 1/4-wave whip antenna has an MCX male connector. Optional higher gain antennas and low-loss coaxial cables have type-N connectors. MCX to type-N adapters and other connector adapters are available. Optional antennas may be accompanied by additional installation instructions.
IGWiPS200-1 Control Room At the control room, there is one master transceiver and complementing I/O: one analog output module, and one digital output module. The total current requirement is 287 mA [75 mA +100 mA + 32 mA + (4 x 20 mA)].
IGWiPS200-1 A. Analog Output and Digital Output Fault Response Selections Three I/O modules (4-Channel Analog Output Module, 8-Channel Digital Output Module, and Combination Input/Output Module) contain DIP switches that may be set by the user to determine the module’s response to the connected transceiver’s loss of an RF Link or to the loss of an input signal. There is a DIP switch for each signal channel allowing individual programming of each channel.
IGWiPS200-1 Pulse Output Module (See Figure 18 on page 26) There are two DIP switches for each channel: switches 1 and 2 for channel 1, switches 3 and 4 for channel 2. Switches 1 (CH1) and 3 (CH2) – Counter or Frequency Mode; Default setting is Counter When Counter mode is selected, the module will output a specific number of pulses as determined by the PLC value written to it by the Pulse Input Module.
IGWiPS200-1 MOUNTING THE DIN RAIL At each installation site, mount the DIN rail and DIN rail mount modules (e.g. transceiver, I/O modules, power supply) in a NEMA enclosure appropriate for the environment and hazardous area classification. Refer to Figure 3 for transceiver and I/O module dimensions. Allow room for: o Physically mounting and wiring the modules and for antenna, power, ground and signal wire runs o Accessories (e.g.
IGWiPS200-1 Each module has a moveable, spring-loaded mounting lip to assist in mounting a module, sliding a module along the DIN rail, and removing a module from the DIN rail. This lip has a slotted tab so the blade of a small screwdriver can be inserted and the lip levered away from the rail. Figure 4 Module Features To mount a row of up to 8 modules on a DIN rail: 1. Interconnect the modules by mating the bus connectors. 2. Hook the fixed mounting lips, see Figure 4, on the DIN rail. 3.
IGWiPS200-1 MOUNTING THE 1/4-WAVE WHIP ANTENNA Mount the 3-1/6" (80.4 mm) high, omnidirectional whip antenna 5 , shown at right, within 5' (1.5m) of the transceiver to allow the supplied 6' (2m) cable to easily reach between the antenna and transceiver. A mounting bracket and three screws are supplied. Antenna spacing (transmitter to receiver) should not exceed 600' to 1000' (183m to 305m). Line of sight is not a requirement.
IGWiPS200-1 Electrical Connections – Power and I/O connections are completed through screw actuated compression terminals. Connector blocks can be removed from a module for wiring, as shown in the two figures below. Insert a small straight-slot screwdriver between a connector block and the faceplate and use a gentle prying motion to separate the connector block from the module. Each connector in a module is uniquely keyed. When installing a connector block, be sure to fully insert the block in the module.
IGWiPS200-1 Transceiver Wiring Examples Five transceiver wiring examples are provided below. Figures 6, 7, and 8 show typical transceiver wiring for 2-wire, 3-wire, and 4-wire current loops. Figures 9 and 10 show two variations on the wiring for a loop powered external analog device. Also shown in Figures 9 and 10 is the wiring for an RF Link annunciator, which can be an input to a PLC or controller or a separate light or siren. A digital output wiring example is provided in Figure 9.

IGWiPS200-1 ASSIGNING AND SETTING I/O MODULE ADDRESSES Module addresses are 1 through 8, as shown on the module faceplates in Figure 19. The top row in the figure shows three I/O modules at a location (for example, at a remote location). The lower row shows the complementary I/O modules at another location (for example, at the control room); transceivers are not shown. Note that the modules in each complementary pair are set to the same address.
IGWiPS200-1 HAZARD LABEL A label, similar to that shown here, is included in a WiPS shipment. The installer or user should post this label in an appropriate, highly visible location near the WiPS modules. Possible label mounting locations include: on the outside of an enclosure housing WiPS modules or inside that enclosure adjacent to the modules.

Carefully insert the faceplate/circuit board assembly in its cover until it snaps into place. When inserting the assembly into its cover, be sure the circuit board enters the card guides in the cover and the circuit board card edge connector mates with the connector in the cover. 6.
