The conditional checks that should be conducted before execution of a switching
command can also be defined:
• Substation interlocking: interlocking of substations is carried out (configuration via
a substation)
• Zone controlled (Bay Specific Interlocking): Logic functions in the device created
with CFC are processed for interlocked switching.
• Switching direction check (scheduled/actual): The switching command is negated
and a corresponding indication is issued if the circuit-breaker is already in the
scheduled position. As soon as this check is activated, the switching direction check
will not only be enabled for interlocked, but also for non-interlocked switching.
• Blocked by protection: CLOSE commands to the switchgear are blocked as soon
as one of the protective functions in the device picks up a fault. TRIP commands,
in contrast, can always be executed.
