CBXCBR is intended for circuit breaker control and status information purposes. The function executes commands and evaluates block conditions and different time supervision conditions. CBXCBR performs an execution command only if all conditions indicate that a switch operation is allowed. If erroneous conditions occur, the function indicates an appropriate cause value. The function is designed according to the IEC 61850-7-4 standard with logical nodes CILO and CSWI.
The circuit-breaker control function has an operation counter for opening cycles. The counter value can be read and written from the setting Operation counter.
