Basic recovery procedure in case of an ERROR STOP:
•
Determine the cause of the error; (indicated in the service menu on the display
or can be read using a web browser);
•
Correct the cause of the error;
•
Perform a controller reset, or alternatively:
Mode selection switch / Service menu / CoDeSys/ web browser;
•
Return the controller to operation.
CP1131 FORCE mode:
FORCE indicates that the application program is running and CoDeSys forces a
value to be written to at least one variable at the start of every cycle. This makes
it evident to the user that the application program might react differently if no such
forced access to the PLC program’s process were to occur.
Status LEDs for CPC++ programs
LEDs 3 to 5 can each be separately controlled by application software.
