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.

cleared when the alarm occurs. An acknowledge command (for example,
PCmd_IOFaultAck or IOFault.OCmd_Ack) are required to acknowledge the
alarm. When set to 0, the Acknowledge bit is set when an alarm occurs
indicating an acknowledged alarm and no acknowledge command is
required.

The following are valid values:
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.

EXAMPLE: If your output card expects a value in the range of 4…20 and
the P_ValveC's CV is ranged 0…100% , P_ValveC can scale the outputs for

Analog/Pulsed Control Valve Output Structure
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.
• Acknowledge data elements (Ack_) are outputs of the instruction that
indicate the corresponding alarm has been acknowledged.
