Time switch interruption
If “time switch interruptible” is enabled in the IO 420 configuration, the “time switch” state can be interrupted using
the “lock” command. The state then changes to “locked” and the flag “time switch aborted” is set. No further change
in state can take place when the flag is set. The flag is reset again when the door is unlocked and locked. The message
“time switch” has to be enabled.
5.3 Module type “2 doors”
The “2 doors” module type can be used for controlling two mutually independent doors. The connection of door
contacts and lock feedback to the inputs is possible. The connection of a release switch is not designated for this
