7 Configuration Services Configuration Configuration services provide the tools to read and set a large number of parameters required for successful communications and control. Each set of tools is grouped in a tabbed page. The Configuration dialog box contains six tabs (Figure 73): General Used to name and describe function blocks and related devices. Position Used to setup configuration parameters. Actuator Used to set advanced position control parameters.
GE Energy ValVueFF Software Interface to FVP CAUTION Don't turn off power for 60 seconds after writing configuration data. Data cannot be saved. See the positioner instruction manual. Do not change Device Tag or Node Address while the NI Configurator or other host software is running. Only change Network parameters when configuring a positioner connected to a segment that is not controlling a process.
Configuration Services Block Tag Info D. D. Rev. The revision of the Device Description is read only. Model The model of the device is read only. Descriptor Use this field for a device description or for a memo (28 char. max). Block Tag Info Each block is assigned a default tag-name that should be renamed by the user. RB The tag of the device resource block. TB The tag of the device transducer block. AO The tag of the device analog output block.
GE Energy ValVueFF Software Interface to FVP Position Tab Use this tab (Figure 74) for the setting up the Transducer Block (TB) valve position configuration parameters. Figure 74 Position Tab - Configuration Dialog Box Servo Parameters Frame The servo parameters are normally set by Auto Tune in Tuning or Calibration. They determine the dynamic response of the valve position control.
Configuration Services Servo Parameters Frame Advanced Position Configuration This is the read-only page (Figure 75) for Transducer Block (TB) advanced position control parameters. To modify the value of any parameter, go to “Advanced Tab” on page 115. Figure 75 Advanced Servo Tuning Parameters Advanced Servo Tuning Parameters Boost On Threshold 1 Control parameter to reduce the effect of deadband in the control relay.
GE Energy ValVueFF Software Interface to FVP Position Limits Frame Use the Position Limits frame (Figure 74) parameters to limit the valve, force the valve to close tightly or open fully at specified positions, and to set the trip points of the limit switches (DI block). You can also activate a warning when a deviation lasts longer than Time 1 or to force the valve to it's failsafe position if the deviation lasts longer that Time 2.
Configuration Services Limit Switch Threshold Limit Testing 1. Isolate the valve from the process. 2. Place the FVP in Manual Operating State. The valve must be calibrated and supplied with correct supply pressure. 3. Measure closed position by: a. Entering a Set Point of -10%. b. Wait for the valve to reach it's final value and record the actual position of the closed mechanical stop. The actual position must be less negative than the target position to verify the valve has reached the stop.
GE Energy ValVueFF Software Interface to FVP CAUTION Use the Time 2 failsafe only for a critical process that must be forced into its failsafe position if the valve is unable to respond to its position Set Point after a reasonable time delay. Do not set the error band to a value that is too small. If Time 2 is used it must be longer than the valve stroking time. A Time 2 value that is too small results in a nuisance failsafe behavior.

GE Energy ValVueFF Software Interface to FVP I (seconds) Integral time or reset time, is the time constant of integral control. Higher values of I cause less integral control action and increase loop stability. However, higher values of I increase the time to eliminate a steady- state position error. 0 turns off integral action and results in a steady-state position error. Sustained deviation can result in failsafe action if T2 is set. Therefore, 0 must be avoided for use in most applications.

13 Failsafe Handling Introduction For the selected positioner, ValVueFF constantly monitors the status of the Transducer Block (TB) actual valve position parameter FINAL POSITION VALUE to report and manage Failsafe events. The actual status of Failsafe is determined by the parameter RELEASE FAILSAFE in TB. To configure the Time 2 parameter to force Failsafe because of sustained deviation, refer to “Configuration Services” on page 79.
GE Energy ValVueFF Software Interface to FVP Failsafe Clear Latched The Fail Safe Status window is updated with the Failsafe Clear Latched condition (Figure 158), when the active condition is cleared. The Clear Latch button is enabled to clear the latch. If the positioner is not in out of service (OOS) operation state, required for clearing the latched state, you are prompted to switch to OOS state.

A Glossary 0xf7 See hexadecimal. This is the number 247 represented in hexadecimal notation. The 0x preamble indicates hexadecimal notation. 1.#INF This is the representation of infinity as expressed in IEEE 754 floating point arithmetic. It is used in fieldbus devices to set a parameter to a value that does not interfere with operation, such as for a limit, for example. Actuator Type The HART Communications Foundation classifies a positioner as type Actuator.
GE Energy ValVueFF Software Interface to FVP CAS Cascade mode A string must be typed exactly in upper-case (capital) letters and lower case. For example Admin is the correct username of the ValVueFF administrator, but admin is rejected at logon. Characteristic The positioner input setpoint command can be selectively modified to provide a desired relationship between setpoint and valve position. In the valve, the relationship between stroke and Cv is also called valve inherent characteristic.
Damping Coefficient The valve response may be made slower for some applications. A value of 0 gives no damping, and a value of 9 gives maximum damping of valve motion. Data Link Layer (DLL) This controls transmission of messages onto the fieldbus, and manages access to the fieldbus through the Link Active Scheduler (LAS). The DLL used by FOUNDATION Fieldbus is defined in IEC 61158 and ISA S50. It includes Publisher/Subscriber, Client/Server and Source/Sink services.
GE Energy ValVueFF Software Interface to FVP Flexible Function Block This is similar to a Standard FB, except that the function of the block, the order and definition of the block parameters, and the time required to execute the block are determined by an application-specific algorithm created by a programming tool. Flexible Function Blocks (FBs) are typically used for control of discrete processes and for hybrid (batch) processes.
HTML Hyper Text Markup Language The standard language for Web Browsers is platform independent. I Integral time or reset time, is the time constant of integral control. Higher values of I cause slower integral action. A value of zero disables integral action. I/P Converter The electro-magnetic device which converts low energy electrical current signal to a pressure which is then amplified by the pneumatic relay.
GE Energy ValVueFF Software Interface to FVP Link Master (LM) A Link Master (LM) is any device containing Link Active Scheduler (LAS) functionality that can control communications on an H1 fieldbus Link. There must be at least one LM on an H1 Link one of those LM devices is elected to serve as LAS. Link Object A Link Object contains information to link Function Block (FB) Input/Output (I/O) parameters in the same device and between different devices.
Object Dictionary An Object Dictionary (OD) contains all Function Block (FB), Resource Block (RB) and Transducer Block (TB) parameters used in a device. Through these parameters, the blocks can be accessed over the fieldbus network. OOS Out of Service mode Out of Service State The FVP positioner transducer, resource and Analog Output, PID blocks are in Out of Service mode. P This is a dimensionless gain factor related to the proportioning action of the algorithm. It ranges from 0 to 5000.
GE Energy ValVueFF Software Interface to FVP Quick Opening (see Characteristic) RB Resource Block RCAS Remote Cascade mode Relay, Pneumatic The component which amplifies the pneumatic control signals to provide a wide range of actuation pressure and to supply and vent at high flow rates for responsive control. Resource Block (RB) This describes fieldbus device characteristics, such as the device name, manufacturer and serial number. There is only one Resource Block (RB) in a device.
STOPS FVP The FVPI runs the STOPS procedure to adjust the positioner to actual valve travel. First the output pressure is reduced to zero, and the position is recorded. That is the position corresponding to 0%. The output pressure is raised to its maximum (based on supply pressure). The position is recorded and corresponds to 100%. Stroke The total range of valve travel. Often used as a verb to describe the process of moving the valve.

G Foundation Fieldbus Overview This section introduces a process example and several concepts used throughout the manual. It briefly introduces Foundation Fieldbus blocks and some of the essential block concepts. The process example is a heat exchanger (Figure 174) with two control valves and three measurement devices. The controls are configured in a cascade arrangement to illustrate concepts of transfer between modes and states of the various levels of control.
GE Energy ValVueFF Software Interface to FVP Reference Model Process The Heat Exchanger model, shown in Figure 174, is not a practical example but it does incorporate elements that illustrate important ValVueFF features. Each module has a device tag used for ValVueFF identification. The process consists of a vessel with a product vapor inflow that is condensed and flows out as a liquid outflow. The tank level is controlled by an outflow control valve, LV 201.
Foundation Fieldbus Function Block Links Function Block Links Each of the control functions is represented in the Control configuration as Foundation Fieldbus function blocks. All the blocks in the temperature cascade are shown in Figure 176. Figure 176 Temperature Cascade Block Diagram They are grouped according to the physical device containing them and they are shown with the links between the blocks, soft wiring for data flow. Similarly, the level loop function blocks are shown in Figure 177.
GE Energy ValVueFF Software Interface to FVP Figure 177 Level Loop Block Diagram To complete the model ValVueFF (Figure 178) is temporarily connected to the heat exchanger's Foundation Fieldbus wiring at an intermediate point.
Foundation Fieldbus Device Operational States and The Heat Exchanger Reference Model segment consists of a Heat Exchanger Host in a control center with a Foundation Fieldbus trunk connected to two junction boxes. One junction box has spurs to the flow and temperature control devices and the other connects to the devices controlling tank level. A power supply with isolation electronics and two terminators completes the configuration.
GE Energy ValVueFF Software Interface to FVP ValVueFF manages the operational states of the positioner and its embedded PID controller by controlling the target modes for each of the function blocks. The actual mode of each block can be different from the target mode. The actual mode is controlled by the block itself in accordance with mode rules based on the quality of the data and modes of the linked blocks.
Foundation Fieldbus Multiple Modes and States Automatic (Auto) A local Set Point value is used by the normal block algorithm in determining the primary output value. The local Set Point value can be written to by an operator through an interface device. Manual (Man) The block output is not being calculated, although it can be limited. It is directly set by the operator through an interface device. The algorithm must initialize so that no bump is experienced when the mode switches.
GE Energy ValVueFF Software Interface to FVP Examples of IVI Operational States Examples of operational states that are combinations of block modes are shown in this section. A new device or a newly configured device can start up in the out of service (OOS) state shown in Figure 180. Figure 180 Out of Service at Startup Table 19 Operation Mode Operation (AI) PID AO TB Configure the transducer block (Auto tuning, travel calibration, diagnostics, etc.
Foundation Fieldbus Transferring to Manual State Table 19 Mode Operation (Continued) Operation (AI) PID AO TB PID single loop control Auto Auto CAS Auto Auto Primary: Auto Secondary: CAS CAS Auto PID cascade loop control Transferring to Manual State Use this procedure to transfer to the manual state which allows ValVueFF to adjust the valve position. The Device Operation State dialog box is shown in Figure 179. 1.

Foundation Fieldbus RCas Mode RCas Mode When the positioner is receiving it's position Set Point from a remote computer system, such as a DCS, then the normal state for the positioner is RCas. In this example, the level control valve, LV201, is receiving it's signal from a DCS. The Analog Output Block (AO) is shown in RCas mode. RCas mode cannot be manually switched to, it is automatically switched to after being configured.
GE Energy ValVueFF Software Interface to FVP Changing Target Operational State When a configuration or other process requires any of the affected function blocks to go into OOS mode, ValVueFF opens a Warning dialog box (Figure 183). Figure 183 Out of Service State Change Warning Message Box Changing to Auto from OOS In OOS, the FVP can be switched to Auto in order to return the device to the previous Auto state by selecting on Auto.
