During control unit startup, the 7-segment display goes on (i.e., displays an "8") for a few seconds
to show it is functioning properly and then goes off.
For information about programming the 7-segment display, to display system and ACSPL
program messages, refer to Chapter 7, "HARDWARE INTERFACE PARAMETERS."

• Control module receives (accepts) only responses to ACSPL input statements and user
defined function keys (FKEY_#).
• Control module transmits only messages generated by ACSPL disp statements.
