1) Basic interlocking functionality: Closing of the circuit breaker can be enabled by a binary input signal. The actual interlocking scheme is
implemented outside the IED. The binary input serves as a "master interlocking input" and when energized it will enable circuit breaker
closing.
2) Extended interlocking functionality: The circuit breaker interlocking scheme is implemented in the IED configuration, based on primary
equipment position information (via binary inputs) and the logical functions available. The signal matrix tool of PCM600 can be used for
modifying the interlocking scheme to suit your application.
