Setting acquisition blocking and the subsequent manual updating are also possible via the IEC 61850
system interface.
Acquisition blocking can also be set via a binary input. This way, acquisition blocking can be set for an indi-
vidual or several switching devices in a feeder simultaneously with an external toggle switch in order to
disable the feeder. For this purpose, every switching device in the Switch function block (circuit breaker or
disconnector switch) has the input signal >Acquisition blocking. This signal can also be set from the
CFC.
