9.2.2.2 COM15 module
Interface adapter for:
- converting csignals to PROFIBUS-DP signals and vice-versa
- for draw-out circuit breakers:
detecting the circuit breaker position in the cradle with auxiliary signaling switches S46, S47 and S48, and emitting the corre-
sponding signals to the cand the PROFIBUS-DP.
- providing special functions via additional inputs and outputs (e.g. to control the circuit breaker and for parameterization)
