Help function output to PLC (H2)
2.8.1
Signals to channel (DB21, ...)
DB21, ...
DBX30.5
Activate associated M01
Edge evaluation: no
Signal(s) updated:
Signal state 1 or
edge change
0 → 1
PLC signals the NCK that the associated
M01
(help function) should be activated.
Signal state 0 or
edge change
1 → 0
De-activate the associated
M01
(help function).
Corresponding to .... DB21, ... DBX 318.5 (associated

2.8.2
Signals from channel (DB21, ...)
DB21, ...
DBB58,
DBB60 - DBB65
M, S, T, D, H, F functions Modification
Edge evaluation: no
Signal(s) updated: Jobcontrolled by NCK
Signal state 1 or
edge change
0 → 1
One M, S, T, An D, H, or F function has been output to the interface with a new value together with
the associated change signal at the beginning of an OB1 cycle.
In this case, the change signal indicates that the appropriate value is valid.
Signal state 0 or
edge change
1 → 0
At the start of the next OB1 cycle, the PLC basic program resets the change signals.
The value of the data concerned is not valid.
