Proportional + Integral + Derivative Enhanced
(P_PIDE)
The P_PIDE (Proportional + Integral + Derivative Enhanced) Add-On Instruction provides the functionality of the Studio 5000 Logix Designer® PIDE function block with a user experience consistent with the rest of the Rockwell
Automation Library of Process Objects. The global object and following faceplate are examples of the graphical interface tools for this Add-On Instruction.

Proportional + Integral + Derivative Enhanced (P_PIDE)
Use this instruction when you plan to use the PIDE for loop control and provide visualization to the operator.
The primary operations of the P_PIDE Add-On Instructions and its faceplate include the following:
•All functions of the PIDE built-in instruction for PID loop control
•Process Library alarm objects for deviation alarms, and additional alarm status information and functionality, including limits, deadbands, and severities
•Additional context for display, including a description, label, tag, and engineering units
•P_Mode (mode) object for ownership
•Links for the P_Intlk (interlocks) instruction for interlocking
•Power-up Setpoint, Output, and Loop mode settings
You must have a license to edit the autotune tag entry field on the PIDE instruction. Do these steps to enable the functionality.
1.Open the Logic routine of the ‘P_PIDE_only’ Add-On Instruction.
2.Edit the function block diagram to set the autotune tag to 'Ref_Autotune'.
3.Save your changes and download to your controller.
Once this change has been made, the outer P_PIDE instruction automatically checks on powerup for response from the Autotune function and automatically enables the Autotune button on the faceplate. This is a supported end-user/solution-provider enhancement that does not void tech support.
For information on how to use the Autotune function, refer to the following Logix Designer online help topics:
•Function Block Properties Dialog Box – Autotune Tab Overview (PIDE)
•PIDE Autotune Dialog Box Overview

Proportional + Integral + Derivative Enhanced (P_PIDE)
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_PIDE_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.

This section describes the parameter references for this Add-On Instruction.
Input parameters include the following:
•Input data elements (Inp_) are typically used to connect field inputs from
I/O modules or signals from other objects.
•Configuration data elements (Cfg_) are used to set configurable capabilities and features of the instruction.
•Commands (PCmd_, OCmd_, MCmd_) are used by program logic, operators, and maintenance personnel to request instruction actions.
•Settings (PSet_, OSet_, MSet_) are used by program logic, operators, and maintenance personnel to establish runtime setpoints, thresholds, and so forth. A Setting (without a leading P, O, or M) establishes runtime settings regardless of role or mode.

|
|
|
|
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_PIDE object has |

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 |
|
|
|

status. When these parameters are 1, the alarm is latched ON when the alarm |
Cfg_HiDevResetReqd |

Proportional + Integral + Derivative Enhanced (P_PIDE)
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 can also 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 can also 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.
•Ready data elements (Rdy_) are bit outputs of the instruction used by the
HMI to enable or disable Command buttons and Setting entry fields.
