Component Categories and Types

We divide the Control Builder components into these two major categories:
Hardware Relation Category (physical equipment)
Functional Relation Category
Hardware relation category
The hardware relation category includes the physical equipment blocks provided in Control Builder. These blocks let you quickly integrate the related control hardware into your control strategy. Figure 1.1 on page 1-2 shows the physical equipment that relates to the corresponding hardware relations covered in this document for a typical non-redundant system. Figure 1.2 on page 1-3 shows the physical equipment that relates to the corresponding hardware relations for a typical redundant system.

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.

Introduction to Control Builder Components 1-5
Functional relation category
Control Builder includes comprehensive libraries of function blocks that streamline the control strategy configuration process. You simply “drag and drop” selected blocks into a Control Module and/or Sequential Control Module container to emulate the necessary functional requirements of your process.
See the Control Builder Reference Manual, publication 1757-RM808, for more information.
The functional relation category conveniently groups function blocks according to a related functional block type or component library. The component libraries provide a convenient way to group related function blocks for easy access and reference.
Figure 1.3 on page 1-5 shows the general graphic orientation and Windows look-and-feel of Control Builder.

1-6 Introduction to Control Builder Components
Functional block types
Table identifies the functional block types used to represent a group of corresponding function blocks provided in Control Builder. These block types are used as a way to simplify information retrieval for a given function block, and do not necessarily correspond to an actual Control Builder function.
Functional Blocks
Type Description
System/ Continuous Control/ Sequential Control
Auxiliary Includes block types for performing auxiliary control functions, such as: calculation, general
Device Control Provides a multi-input/multi-output function that provides an interface to discrete devices such as
Data Acquisition Provides signal conditioning for a process inputValue from another function block.
I/O Channel (IOC) Includes channel block types (analog input, analog output, digital input, digital output, pulse width
Logic Provides a set of Boolean, selection and comparison functions to be used as a basis for integrated
Regulatory Control Includes block types for building internal control loops.
Sequential Control Module Includes block types for building a sequential control function.
Utility Includes block types for performing utility control functions, such as: status flag, numeric storage
ControlNet Interoperability (Exchange) Blocks
Control Module (CM) is a Control Builder “container” that uses predefined continuous (discrete) control function blocks to define a given process control strategy. Sequential Control Module (SCM) is a Control Builder “container” that uses predefined sequential control function blocks to define the sequential operation for a given process control strategy.

modulator) to represent I/O points that are device independent; each I/O channel type has a standard interface with control function blocks. This category also includes array channel blocks to support communications with the associated Serial Interface Module and the connected Field Terminal Assembly (FTA) device. You assign an array channel block to one of the SIM block’s 32 channels as well as designating which of the two FTAs it is associated with. The array channel block types are flag, numeric, and text.

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.

Control Execution Environment (CEE)
Description Provides control functionality for associated Control Processor Module block. This blocks parameters characterize the
CEE within the CPM. In the future, multiple CEEs may be assigned to a single CPM. This block always runs at an execution period of 2 seconds. There are two versions of the CEE available, the standard version CEE-50ms, and the fast version CEE-5ms.
Function Publishes parameters describing the status and configuration of the CEE.
Processes the computation of statistical parameters and notification reporting.
Runs on the CPM hardware platform. In the future, CEE will run on other platforms as well.
Serves as a faceplate for any parameters whose scope corresponds to that of the CEE rather than the CPM as a
whole.
Supports configurable subscription rate for peer-to-peer communications.
Supports peer-to-peer communications among CEEs assigned to CPMs located in the same management domain.
Sequential Control Module function blocks are supported. Special care should be taken in configuring the SCMs in
5 msec CEE.
