1-4 Introduction to Control Builder Components
Physical equipment block types
Table identifies the physical equipment block types provided to
represent corresponding major control hardware components. The
Control Execution Environment (CEE) block is included as one of
these block types because of its relationship with the Control
Processor, although it is a functional type more than a physical one.
Physical Equipment Blocks
Type Description
Control Processor Module (CPM) Defines name/location and Control Execution
Environment (CEE) assignment for Primary and
Secondary CPMs in connected Hybrid Controllers.
This CPM is redundancy compliant.
Control Execution Environment (CEE) Supports block execution and communications in
given CPM.
Redundancy Module (RM) Defines name/location of Primary and Secondary
Redundancy Modules in Redundant Chassis Pair.
This module is redundancy compliant.
I/O Modules (IOM) Provides links for I/O channels to interface
physical I/O module to given Control Processor
Module. This includes 1756, 1757, 1797 FLEX Ex
and 1794 FLEX I/O modules.
Serial Interface Module (SIM) Provides configuration and communication
software to enable devices to communicateVia
an ASCII serial protocol to perform bi-directional
data exchange directly with the ProcessLogix
Control Processor.
Pulse Input Module Serves as the interface board between the
ProcessLogix Controller and field transducers
such as tachometers, flow meters, and magnetic
pickups. Module block descriptions are listed
under Functional Blocks, on page 3-73.
