The control coprocessor expands the capability of a programmable-
controller system by running C, BASIC, and assembler programs that
perform tasks such as:
manipulating and analyzing input, output, and other information
gathered from the programmable controller
communicating with devices external to the programmable controller
system via the Ethernet
R
or asynchronous serial communication port(s)
These user programs run asynchronously to, and independently of, the
programmable-controller control logic, but they do have access to its
memory. You can use the control-logic programs in your programmable
controller to start and stop your C, BASIC, or assembler programs.
