Introduction to Control Builder Components

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.

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.

Publication 1757-RM810A-EN-P - May 2002

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

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.

Auxiliary Includes block types for performing auxiliary control functions, such as: calculation, general

linearization and totalization.

Device Control Provides a multi-input/multi-output function that provides an interface to discrete devices such as

motors, pumps, solenoidValves, and motor-operatedValves.

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

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.

Logic Provides a set of Boolean, selection and comparison functions to be used as a basis for integrated

logic control.

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

and timer capabilities. Blocks have been added for message, data array, and parameter type

convert support.

ControlNet Interoperability

(Exchange) Blocks

Includes block types for performing ControlNet Interoperability functions, such as: Flag, Numeric

and Text storage.

Pulse Input Channel/ Module Blocks Provides a standard interface to the Pulse Input Module, 1757-PIM.

PROFIBUS Interface Provides a standard interface to the PROFIBUS Interface Module, SST-PFBCLX.

Fieldbus Interface Provides a standard interface to the Fieldbus Interface Module, 1757-FIM.
