Functional Blocks
Overview
This section provides detailed reference data for each functional block
type that is part of the functional relation category for the Control
Builder. It presents the block types associated with a given
component library. The reference data is organized alphabetically by
component library/block type, and then alphabetically within each
type by the function block name.
See the ProcessLogix Function Block Parameter Reference Manual,
publication 1757-RM811, for definitions of each parameter.
System Blocks
CONTROLMODULE (Continuous Control)
Description One of two system container blocks supported by CEE. It holds continuous and discrete function blocks.
Function Configurable building block for defining control strategies. Lets you encapsulate strategies according to function.
It provides these basic services for configured blocks:
•
Serves as the unit of load for continuous and discrete control strategies.
•
Transfers data between passive parameters that have no associated active connector.
•
Executes component function blocks in an established order, which is configurable or arbitrarily determined by the
CM.
•
Provides independent tag names component blocks their parameters.
•
Serves the execution master for continuous and discrete control strategies.
Inputs Input parameters for component blocks that connect to other CMs and SCMs.
Outputs Output parameters for component blocks that connect to other CMs and SCMs.
