Analog/Pulsed Control Valve (P_ValveC)

Guidelines

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)

Functional Description

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.

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.

	Type
Cfg_ShedHold	BOOL		0	1	= Hold output on interlock or bad CV.
				0	= Go to Cfg_IntlkCV.
Cfg_ShedOnIOFault	BOOL		0	1	= Take shed action (hold or interlock CV) and alarm on I/O Fault.
				0	= Alarm only on I/O Fault.
				IMPORTANT: If a condition is configured to shed the device on a fault, a
				reset is required to clear the shed fault to command the device.
Cfg_SkipRoCLim	BOOL		0	1	= Skip Rate of Change limiting in Interlock, Maintenance, Override
				modes.
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	BOOL		0	1	= Program/operator settings track override/hand CV.
Cfg_HasOpenLS	BOOL		0	1	= Valve provides an open limit switch signal.
Cfg_HasClosedLS	BOOL		0	1	= Valve provides a closed limit switch signal.
Cfg_UseOpenLS	BOOL		0	1	= Valve Open LS - use for open/closed status.
Cfg_UseClosedLS	BOOL		0	1	= Valve Closed LS - use for open/closed status.
Cfg_LSFail	BOOL		1	1	= Both switches On = fail.

Cfg_HasIntlkObj	BOOL		0	1	= Tells HMI an interlock object (for example, P_Intlk) is used for
				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
				‘ValveC123_Intlk’.
Cfg_HasCVNav	BOOL		0	1	= Tells HMI to enable navigation to a connected CV object.
Cfg_PCmdClear	BOOL	Mode.Cfg_PCmdClear	1	When this parameter is 1, program commands are cleared once they are
				acted upon. When set to 0, program commands remain set until cleared by
				the application program logic.
				IMPORTANT: Clearing this parameter online can cause unintended
				program command execution.
Cfg_ProgDefault	BOOL	Mode.Cfg_ProgDefault	0	This parameter defines the default mode. When this parameter is 1, the
				mode defaults to Program if no mode is being requested. When this
				parameter is 0, the mode defaults to Operator if no mode is being
				requested.
				IMPORTANT: Changing this parameter online can cause unintended mode
				changes.
Cfg_OvrdIntlk	BOOL		0	1	= Override ignores bypassable interlock.
				0	= Override mode uses all interlocks.
Cfg_HasIntlkTripAlm	BOOL	IntlkTrip.Cfg_Exists	0	These parameters determine whether the corresponding alarm exists and
				is checked or if the alarm does not exist and is not used.

Table 7 - P_ValveC Input Parameters

Input Parameter	Data	Alias For	Default	Description
	Type
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.
Cfg_MinCV	REAL		0.0	Minimum CV (in CV engineering units, for limiting).
Cfg_MaxCV	REAL		100.0	Maximum CV (in CV engineering units, for limiting).
Cfg_MaxCVRoCInc	REAL		10.0	Maximum allowed CV Rate of Change (increasing) setting (engineering
				units/second).
Cfg_MaxCVRoCDec	REAL		10.0	Maximum allowed CV Rate of Change (decreasing) setting (engineering
				units/second).
Cfg_IntlkCV	REAL		0.0	CV (target in engineering units) when interlocked (used when
				Cfg_ShedHold is configured to 0).
Cfg_CVEUMin	REAL		0.0	These parameters must be set to the range of the signal connected to the
				setting inputs (for example, PSet_CV). The output is then scaled to the
Cfg_CVEUMax			100.0
				values set by Cfg_CVRawMin and Cfg_CVRawMax.
Cfg_CVRawMin	REAL		0.0	These parameters must be set to match the CV range of the output signals
				(Out_CV) in raw units.
Cfg_CVRawMax			100.0
				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
				you by setting Cfg_CVRawMin to 4, Cfg_CVRawMax to 20, Cfg_CVEUMin
				to 0, and Cfg_CVEUMax to 100.
Cfg_FdbkRawMin	REAL		0.0	These parameters must be set to the range of the signal connected to the
				feedback signal (Inp_PosFdbk). The inputs are then scaled to the values set
Cfg_FdbkRawMax			100.0
				by Cfg_CVEUMin and Cfg_CVEUMax.
Cfg_CycleT	REAL		10.0	Open and close pulse output overall period (seconds).
Cfg_OpenRate	REAL		1.0	Rate at which valve moves when opening (CV engineering units/second).
Cfg_CloseRate	REAL		1.0	Rate at whcih valve moves when closing (CV engineering units/second).
Cfg_MaxOnT	REAL		5.0	Open and close pulse output maximum on time (seconds).

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.
