Physical Equipment Blocks
Overview
This section provides detailed reference data for each physical
equipment block type that is part of the hardware relation category for
Control Builder.
See the ProcessLogix Function Block Parameter Reference Manual,
publication 1757-RM811A-EN-P, for definitions of each parameter.
Control Processor Module (CPM)
Description Identifies the primary and secondary Control Processor Modules (CPM) and associated CEE to implement the control
strategy built in the Control Builder application. This block’s parameters characterize the redundant CPM as a whole.
This block always runs at an execution period of 2 seconds. It is redundancy compliant.
Function
•
Supports Hybrid Controller Redundant Chassis Pair hardware configurations.
•
Publishes parameters describing the status and configuration of the CPM.
•
Processes the computation of statistical parameters and notification reporting.
•
Serves as a faceplate for any parameters whose scope corresponds to that of the entire CPM.
•
Secondary waits to take control if the “Primary” fails.
•
The address of the Secondary chassis equals the address of the Primary chassis plus one.
Inputs Integrated Control Protocol (ICP) communications
Outputs See above.
