“PLC Program” area

The signals are green (OK), otherwise grey or red (error). They could be yellow if the error situation has been ceased after page display.

• Not Loaded / Loaded: it tells if the 1131 PLC program has been successfully loaded in memory.
• Not Running / Started: if green, the PLC program has been started. When yellow, the PLC has been restarted after a stop (e.g.: a breakpoint).
• Time > 20sec: when red, the PLC has not been started in expected time (20 seconds from the first page visualization). When yellow, the PLC is now running but it remembers that it was started delayed by over 20 sec.
