Chapter 1
Introducing the Control Coprocessor
1-2
You can use the control coprocessor for applications such as:
calculating complex math or application-specific algorithms using
C and/or BASIC programs
production scheduling or historical-data logging/tracking
high-speed search and compare of very large files or look-up tables
protocol conversion for interfacing a programmable controller with
a variety of field devices
ControlĆCoprocessor Modules
The control coprocessor consists of a main module and an optional serial
expander module. Table 1.A lists catalog numbers for the control-
coprocessor main modules and the optional serial expander module.

¬ See Appendix A, Table A.3 for more detailed information on memory usage.
The control-coprocessor main module is a 1-slot module. If you use both
the control-coprocessor main module and a serial expander module, you
require 2 slots. The figure at the left shows a 2-slot module with a
1771-DMC1 or -DMC4 main module and a serial expander module.
The control coprocessor is a member of the 1771 Universal I/O System.
You can use it with or without a programmable controller.
