Functionality
The circuit breaker position information can be communicated with the IEC 61850
GOOSE messages. The position information is a double binary data type which is fed to
the POS input.
T_POS_CL and T_POS_OP are used for extracting the circuit breaker status information.
Respectively, T_POS_OK is used to validate the intermediate or faulty breaker position.
