13 Operator Panel Interface (DB 40)
13.4 Menu selection interface
INSERTION ALREADY ACTIVE
1 signal: By the PLC operating system if recognition that a different PLC has already activ-
ated a menu selection does not occur until after triggering a menu selection. This
bit is set if several PLCs attempt to execute an insertion at the same time in a
single cycle.
0 signal: By the PLC operating system after the user has confirmed the acknowledgement
by resetting START SIGNAL.
OWN INSERTION ACTIVE
1 signal: By the PLC operating system if the first insertion was implemented without any
errors. The PLC is therefore in the first insertion menu at least.
0 signal: By the PLC operating system if no own PLC insertion is active.
INSERTION FROM OTHER PLC ACTIVE
1 signal: An insertion from another PLC is active.
0 signal: No insertion from another PLC is active.
Note:
This is a static signal that is updated by the PLC operating system every cycle.
This signal should be scanned by the PLC user program before an insertion. Insertions cannot
be made if the other PLC has inserted a menu.
