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.
