This section covers CC utility functions of the control coprocessor such as:

initialization

error handling

ASCII display interface functions

synchronizing a control-coprocessor calling task to a PLC-5

programmable-controller ladder-logic program scan

Initialize ControlĆCoprocessor Function

Use the CC_INIT function to initialize the control coprocessor.

Important: The CC_INIT function must be called before you can use

any other API library function. Call the CC_INIT function first and once

only in your program.

ControlĆCoprocessor Error Functions

Use control-coprocessor error functions for error messages related to error

numbers. See Table 5.K.

ControlĆCoprocessor ASCII Display Functions

Use the ASCII display functions to show control-coprocessor status

information on the optional serial expander module display. See Table 5.L.
