The function detects the transition from TRUE to FALSE at the CLK input. When the
falling edge is detected, the element assigns the Q output to TRUE. At the next
execution round, the output is returned to FALSE despite the state of the input.

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.
