Functionality

CBXCBR and DCXSWI are intended for circuit breaker and disconnector control
and status information purposes. These functions execute commands and evaluate
block conditions and different time supervision conditions. The functions perform
an execution command only if all conditions indicate that a switch operation is
allowed. If erroneous conditions occur, the functions indicate an appropriate cause
