Control and status indication facilities are implemented in the same package
with CBXCBR, DCXSWI and ESXSWI. When primary components are controlled in
the energizing phase, for example, the correct execution sequence of the control
commands must be ensured. This can be achieved, for example, with interlocking
based on the status indication of the related primary components. The interlocking
on substation level can be applied using the IEC 61850 GOOSE messages between
feeders.
