Function:

This communication object can be used to disable or enable the input of the channel.

If an input is locked (lock object = 1 with no inversion or lock object = 0 with inversion of the lock input), signal changes are not transmitted at this input nor is the signal state sent.

The communication object "A Lock input” can be displayed. The read value corresponds to the actual state of the lock (not the state of the lock object). Inversions of the communication object "A Lock input” are taken into account.

Note:

During initial commissioning or after resetting to the delivery state, this communication object has no value. This means that after the initial download of the configurations made in the ETS, the communication object must receive a value. This is done, for example, by sending a telegram to the group address assigned to the communication object or by actuating the connected switch, which can be used to switch the lock on and off.

Availability:

The "A Lock input” communication object is displayed if the following configurations have been made:

  • Parameter "Function channels A + B” on the "device settings” parameter card
    • Setting: "Single” or "Pairwise"
  • Parameter "Object lock input” or "Lock first channel input object” on the "functions, objects” parameter card
    • Setting: “enable
