Signals to channel (DB21, ...)

DB21, ...
Synchronized action off
DBX1.2
Edge evaluation: No
Signal state 1 All synchronized actions in the channel are locked. This means that no synchronized action is exe‐
cuted.
Signal state 0 Synchronized actions are executed in the channel.

Request / acknowledgment: accept synchronized actions to be inhibited / synchronized actions to
DBX280.1
be inhibited are accepted
Edge evaluation: No
Signal state 1 Acceptance of the inhibit signals from the interface in the channel of the NC has been requested by
the PLC user program.
Signal state 0 After the request to accept the inhibit signals from the interface in the channel, the NC acknowledged
the acceptance by resetting the request:
