﻿The forced position communication object can be initialised after bus voltage return. The switching state of the output can be influenced when the forced position function is being activated.

*No forced position*: In case of bus voltage return, the force-independent parameter "After bus voltage return" (parameter page "Relay output... -> SO... - General") will be executed on return of bus voltage.

Forced position active, switch on: The forced position is activated. The switching output is switched on under forced control.

Forced position active, switch off: The forced position is activated. The switching output is switched off under forced control.

*State before bus voltage failure*: The forced position state last selected and internally stored before bus voltage failure will be tracked after bus voltage return. An ETS programming operation deletes the stored state (reaction in that case same as with "no forced position active"). If the tracked state corresponds to "No forced position", the force-independent parameter "After bus voltage return" (parameter page "Relay output... -> SO... - General") will be executed on return of bus voltage.
