Functionality

The circuit breaker control function CBXCBR is intended for circuit breaker control
and status information purposes. This function executes commands and evaluates
block conditions and different time supervision conditions. The function 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, CSWI and XCBR.
The circuit breaker control function has an operation counter which counts the number
of circuit breaker openings. The counter value can be read and written remotely from
the place of operation or via the LHMI.
