Analog/Pulsed Control Valve (P_ValveC)

The P_ValveC (Analog/Pulsed Control Valve) Add-On Instruction manipulates a control valve by using an analog signal or discrete signals, and monitors the valve by using an analog position feedback. The global objects and following faceplate are examples of the graphical interface tools for this Add-On Instruction.

Global Objects

Faceplate

Add-On Instruction

Guidelines

Use this instruction in these situations:

• You want to use a control (modulating) valve where 0…100% is mapped to the percentage open.

• The valve requires an analog output (or analog value over a network) for the target position, or the valve requires a pair of discrete outputs (or discrete signals over a network) to tell it when to move toward fully closed and when to move toward fully open. The discrete outputs can be held (for a motor-operated control valve) or pulsed (for a ratcheting control valve).

• If you use discrete outputs, and optionally if you use the analog output, the valve provides an actual position feedback signal.

Rockwell Automation Publication SYSLIB-RM034E-EN-P - February 2017 7

Chapter 4 Analog/Pulsed Control Valve (P_ValveC)

Do not use this instruction in these situations:

• You are using a single analog output control valve with a PID loop (the

P_PIDE Add-On Instruction or the PIDE built-in instruction). The CVEU signal can be used directly to drive the valve or you can use the P_AOut (Analog Output) Add-On Instruction.

• You are using a two-state valve, such as a motor-operated or solenoid-operated valve that is driven only fully open or fully closed and not used to control flow or pressure. Use the appropriate two-state valve instruction instead:

• P_ValveMO for motor operated valve (also for a dual solenoid operated

valve)

• P_ValveSO for a single solenoid operated valve

Functional Description

The P_ValveC Instruction provides the following capabilities:

• Program and operator entry of the target valve position (percentage of the valve opening).

• Ramping of the valve position to the entered target at a specified rate of change (percent per second).

• Scaling of the Position Feedback from the valve from raw (I/O card or network value) units to percent open.

• Monitoring of Interlock conditions. When an Interlock condition is not OK, the valve can be configured to hold its current position or shed to a configured Interlock position.

• Monitoring for I/O communication faults. When an I/O communication fault occurs, this instruction can be configured to alarm only, or to shed, either to hold the current position or go to the configured Interlock position.

• Provides alarms for Interlock trip, I/O fault, or an actuator-declared fault.

• Provides full-open and full-closed status based on user-specified ranges for

analog position feedback, or based on optional valve travel limit switches.

• Provides an ‘available’ status when the control valve instruction is in Program mode and the valve is capable of being controlled.

The diagram shows the functional characteristics of the P_ValveC Add-On Instruction.

Required Files

Add-On Instructions are reusable code objects that contain encapsulated logic that can streamline implementing your system. This lets you create your own instruction set for programming logic as a supplement to the instruction set provided natively in the ControlLogix® firmware. An Add-On Instruction is defined once in each controller project, and can be instantiated multiple times in your application code as needed.

Controller File

The P_ValveC_3_5-00_AOI.L5X Add-On Instruction must be imported into the controller project to be used in the controller configuration. The service release number (boldfaced) can change as service revisions are created.

Visualization Files

This Add-On Instruction has associated visualization files that provide a common user interface. These files can be downloaded from the Product Compatibility and Download Center at

http://www.rockwellautomation.com/rockwellautomation/support/pcdc.page.

IMPORTANT

The visualization file dependencies require Process Library content imports to occur in a specific order as reflected in the following tables:

• Images

• Global Objects

• Standard Displays

• HMI Tags

• Macros

Images are external graphic files that can be used in displays. They must be imported for FactoryTalk View to make use of them.

When PNG files are imported, they are renamed by FactoryTalk View with a .bmp file extension, but retain a .png format.

Operations

This section describes the primary operations for Add-On Instructions.

Modes

This instruction uses the following standard modes, which are implemented by using an embedded P_Mode Add-On Instruction.

Table 10 - Modes

Mode Description

Operator The Operator owns control of the group. Operator commands (OCmd_) and Operator settings

(OSet_) from the HMI are accepted.

Program Program logic owns control of the group. Program commands (PCmd_) and Program settings

(PSet_) are accepted.

Override Priority logic owns control of the group and supersedes Operator and Program control. Override

Inputs (Inp_OvrdCmd and other Inp_OvrdXxxx values) are accepted. If so configured, bypassable interlocks and permissives are bypassed.

Maintenance Maintenance owns control of the group and supersedes Operator, Program, and Override control.

Operator commands and settings from the HMI are accepted. Bypassable interlocks and permissives are bypassed, and device timeout checks are not processed.

Hand Hardwired logic or other logic outside the instruction owns control of the group. The instruction

tracks the state of the device for bumpless transfer back to one of the other modes.

No Mode The device is disabled and has no owner because the EnableIn input is false. The main

instruction Logic routine is not being scanned. See Execution section for more information on EnableInFalse processing.

See Rockwell Automation Library of Process Objects: Common Mode Block (P_Mode) Reference Manual, publication SYSLIB-RM005, for more information.

Alarms

This instruction uses the following alarms, which are implemented by using embedded P_Alarm and P_Gate Add-On Instructions.

Alarm Name P_Alarm Name P_Gate Name Description

Can’t Start CantStart None Raised when there are not enough motors available to

start to satisfy the entered Demand. Too many motors are faulted or stopped in a mode other than Program.

Can’t Stop CantStop None Raised when there are not enough motors available to

stop to satisfy the entered Demand. Too many motors are running in a mode other than Program.

Interlock Trip IntlkTrip None Raised when the motor is running and an interlock

'not OK' condition causes the motor to stop. If interlocks are not bypassed, a bypassable interlock

or a non-bypassable interlock 'not OK' condition initiates an interlock trip. If interlocks are bypassed, only a non-bypassable interlock 'not OK' condition initiates an interlock trip.

Parameters of the P_Alarm object can be accessed by using the following convention: [P_Alarm Name].[P_Alarm Parameter].

22 Rockwell Automation Publication SYSLIB-RM034E-EN-P - February 2017

Analog/Pulsed Control Valve (P_ValveC) Chapter 4

Simulation

Simulation in P_ValveC holds the analog output at zero and holds the discrete pulse outputs off while simulating a working valve. The I/O fault input is ignored.

You must set the Inp_Sim parameter in the controller to ‘1’ to enable simulation.

The Loopback Test icon is displayed at the bottom left of the Operator faceplate indicating the device is in simulation.

When you have finished in simulation, set the Inp_Sim parameter in the controller to ‘0’ to return to normal operation.

Execution

The following table explains the handling of instruction execution conditions.

Condition Description

EnableIn False (false rung) Processing for EnableIn False (false rung) is handled the

Powerup (prescan, first scan) Processing of modes and alarms on pre-Scan and

Postscan No SFC Postscan logic is provided.

same as if the Control Valve were Disabled by Command. The discrete open and close outputs are de-energized. The analog CV output is de-energized (zeroed). The Control Valve instruction is shown as Disabled on the HMI. The mode is shown as NO MODE.

Powerup is handled by the embedded P_Mode and P_Alarm instructions - refer to their specifications for details. On Power-up, the Control Valve ownership is cleared and any commands received while the controller was in PROG mode are discarded; otherwise, all data remains in the state it was in at power down.

Rockwell Automation Publication SYSLIB-RM034E-EN-P - February 2017 23

Chapter 4 Analog/Pulsed Control Valve (P_ValveC)

Programming Examples

This section shows two examples for using the P_Valve C instruction.

Example 1: Manual Loading Station

This example uses the P_ValveC instruction to implement a manual loading station for a pressure control valve that is used to regulate gas supply to a process. The control valve in our example has open and closed limit switches and a position feedback. The desired valve position is provided by the operator through the HMI faceplate.

The field inputs for position feedback, open limit switch, and closed limit switch (as shown in the illustration) are connected to the instruction inputs Inp_PosFdbk, Inp_OpenLS, and Inp_ClosedLS. The Out_CV is connected to the field output going to the valve.

The parameters Cfg_HasOpenLS and Cfg_HasClosedLS are both set to 1 so the instruction knows the field is providing open and closed limit switches. The parameters Cfg_UseOpenLS and Cfg_UseClosedLS are set to 1 so that these limit switches are used to determine device status.

The analog output card is expecting an output in units of 4…20 mA; however, the faceplate shows the value in terms of 0…100% open. Therefore, the scaling parameters are set as follows:

Cfg_CVEUMin: 0 Cfg_CVEUMax: 100 Cfg_CVRawMin: 4 Cfg_CVRawMax: 20

The feedback signal is also provided in units of 4…20 mA, so the parameters Cfg_FdbkRawMin and Cfg_FdbkRawMax are set to 4 and 20, respectively.

We want to limit the operator entry of the desired valve position to 80% open by setting Cfg_MaxCV to 80.

24 Rockwell Automation Publication SYSLIB-RM034E-EN-P - February 2017

Analog/Pulsed Control Valve (P_ValveC) Chapter 4

The parameters Cfg_HasIOFaultAlm, Cfg_HasActuatorFaultAlm, and Cfg_HasIntlkTripAlm are all set to 0 to indicate that no alarms are necessary for this device.

Lastly, configure the following local configuration tags to drive the text on the HMI faceplate. In this example, they are set as follows:

Cfg_Tag: PV110812 Cfg_Label: Gas Supply Valve Cfg_Desc: Gas Supply Valve Manual Loading Station Cfg_EU: %

Example 2: Ratcheting Control Valve

This example uses the P_ValveC instruction to automate a ratcheting valve that is driven open or closed by using two discrete outputs to control flow. The flow valve in our example has a position feedback. The desired valve position is provided by an output of a control algorithm that is elsewhere in logic.

In this example, the field inputs for position feedback are wired (or connected) to the instruction input Inp_PosFdbk. Out_Open and Out_Close are connected to the field outputs going to the valve. The input to the instruction to set valve position is wired to PSet_CV. Cfg_ProgDefault is set to 1 so the instruction defaults to Program mode.

The analog output is not used; however, the faceplate shows the value in terms of 0…100% open. Therefore, the scaling parameters are set as follows:

Cfg_CVEUMin: 0 Cfg_CVEUMAx: 100 Cfg_CVRawMin: 0 - default Cfg_CVRawMax: 100 - default

The feedback signal is provided in units of 4…20 mA, so the parameters Cfg_FdbkRawMin and Cfg_FdbkRawMax are set to 4 and 20, respectively.

Rockwell Automation Publication SYSLIB-RM034E-EN-P - February 2017 25

Chapter 4 Analog/Pulsed Control Valve (P_ValveC)

In this example, the ratcheting control valve is to be adjusted by cycling the open or close valve command for a period of time proportional to the amount the valve is to be moved. Cfg_CycleT is set to 10, to define the overall period of the cycle to cycle on and off the open or close output. Cfg_OpenRate and Cfg_OpenCloseRate are both set to 1, which means the required valve output is energized 1 second for every 1% difference between the desired position and the feedback position.

Cfg_MaxOnT is set to 5 so that the output is energized for no more than 5 seconds of the 10-second cycle time to allow for the valve to move, and the feedback to be verified before the next cycle. Cfg_MinOnT is set to 1 so that the output does not pulse if the calculated pulse time is less than 1 second.

The parameters Cfg_HasIOFaultAlm, Cfg_HasActuatorFaultAlm, and Cfg_HasIntlkTripAlm are all set to 0 to indicate that no alarms are necessary for this device.

Lastly, configure the following local configuration tags to drive the text on the HMI faceplate. In this example, they are set as follows:

Cfg_Tag: FV110813 Cfg_Label: Flow Control Valve Cfg_Desc: Flow Ratcheting Control Valve Cfg_EU: %
