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
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 |

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
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.

Chapter 4 Analog/Pulsed Control Valve (P_ValveC)
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.
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.
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.

Cfg_SetTrack |
BOOL |
|
1 |
This parameter is used to set up bumpless behavior of setting parameters |
|
|
|
|
|
when switching modes. When this parameter is 1, in Program mode the |
|
|
|
|
|
operator settings track the program settings; in Operator mode the |
|
|
|
|
|
program settings track the operator settings; and the simulation inputs |
|
|
|
|
|
match the output values (transitions are bumpless). |
|
|
|
|
|
When this parameter is 0, the operator settings and program settings are |
|
|
|
|
|
not modified by this instruction. In this case, when the mode is changed, |
|
|
|
|
|
the effective value of the setting can change depending on the program- |
|
|
|
|
|
set and operator-set values. |
|
|
|
|
|
|
|
Cfg_SetTrackOvrdHand |

Inp_IntlkOK and navigation to the interlock object’s faceplate is enabled. |
|
|
|
|
|
IMPORTANT: The name of the interlock object in the controller must be |
|
|
|
|
|
this object's name with the suffix ‘_Intlk’. For example, if your P_ValveC |
|
|
|
|
|
object has the name ’ValveC123’, then its interlock object must be named |
|
|
|
|

Cfg_IntlkTripResetReqd |
BOOL |
IntlkTrip.Cfg_ResetReqd |
0 |
These parameters determine whether a reset is required to clear the alarm |
|
|
|
|
status. When these parameters are 1, the alarm is latched ON when the |
Cfg_ActuatorFaultResetReqd |
|
ActuatorFault.Cfg_ResetReqd |
|
|
|
|
alarm occurs. After the alarm condition returns to normal, a reset is |
||
|
|
|
|
required to clear the alarm status (for example, OCmd_Reset, Inp_Reset, |
Cfg_IOFaultResetReqd |
|
IOFault.Cfg_ResetReqd |
|
|
|
|
or IOFault.OCmd_Reset are required to clear Alm_IOFault alarm after the |
||
|
|
|
|
|
|
|
|
|
alarm is set and the value returns to normal). When these parameters are |
|
|
|
|
0, no reset is required and the alarm status is cleared when the alarm |
|
|
|
|
condition returns to normal. |
|
|
|
|
IMPORTANT: If the reset clears the alarm, it also acknowledges the alarm. |
|
|
|
|
|
Cfg_IntlkTripAckReqd |
BOOL |
IntlkTrip.Cfg_AckReqd |
1 |
These parameters determine whether an acknowledgement is required for |
|
|
|
|
an alarm. When these parameters are 1, the acknowledge (ack) bit is |
Cfg_ActuatorFaultAckReqd |
|
ActuatorFault.Cfg_AckReqd |
|
|
|
|
cleared when the alarm occurs. An acknowledge command (for example, |
||
|
|
|
|
PCmd_IOFaultAck or IOFault.OCmd_Ack) are required to acknowledge the |
Cfg_IOFaultAckReqd |
|
IOFault.Cfg_AckReqd |
|
|
|
|
alarm. When set to 0, the Acknowledge bit is set when an alarm occurs |
||
|
|
|
|
|
|
|
|
|
indicating an acknowledged alarm and no acknowledge command is |
|
|
|
|
required. |
|
|
|
|
|
Cfg_IntlkTripSeverity |
INT |
IntlkTrip.Cfg_Severity |
500 |
These parameters determine the severity of each alarm that gauges the |
|
|
|
|
color and symbol that are used to indicate alarm status on the faceplate |
Cfg_ActuatorFaultSeverity |
|
ActuatorFault.Cfg_Severity |
1000 |
|
|
and global object. |
|||
|
|
|
|
The following are valid values: |
Cfg_IOFaultSeverity |
|
IOFault.Cfg_Severity |
1000 |
|
|
1…250 = Low |
|||
|
|
|
|
|
|
|
|
|
251…500 = Medium |
|
|
|
|
501…750 = High |
|
|
|
|
751…1000 = Urgent |
|
|
|
|
IMPORTANT: For FactoryTalk View software, version 7.0, these severity |
|
|
|
|
priorities drive only the indication on the global object and faceplate. The |
|
|
|
|
Alarm & Events definition severity drives the color and symbol that is used |
|
|
|
|
on the alarm banner and alarm summary as well a the value returned by |
|
|
|
|
the FactoryTalk Alarm and Events software display commands. |

Output parameters include the following:
•Output data elements (Out_) are the primary outputs of the instruction, typically used by hardware output modules; however, they can be used by other application logic.
•Value data elements (Val_) are numeric outputs of the instruction for use by the HMI. Values also can be used by other application logic or software packages.
•Source and Quality data elements (SrcQ_) are outputs of the instruction used by the HMI to indicate PV source and quality.
•Status data elements (Sts_) are bit outputs of the instruction for use by the HMI. Status bits also can be used by other application logic.
•Error data elements (Err_) are outputs of the instruction that indicate a particular configuration error. If any Err_ bit is set then the Sts_Err configuration error summary status is set and the Invalid Configuration indicator is displayed on the HMI.
•Not Ready data elements (Nrdy_) are bit outputs of the instruction for use by the HMI for displaying the Device Not Ready indicator. Not Ready bits can also be used by other application logic.
•Alarm data elements (Alm_) are outputs of the instruction that indicate a particular alarm has occurred.
