Operation principle

The DATAVALID output will be HIGH if the incoming message is with valid data.
The COMMVALID output will become LOW when the sending IED is under total
failure condition and the GOOSE transmission from the sending IED does not happen.
The TEST output will go HIGH if the sending IED is in test mode.

The input of this GOOSE block must be linked either in SMT by means
of a cross or in ACT by means of a GOOSE connection (in case easy
GOOSE engineering is enabled) to receive the measured value.
The implementation for IEC 61850 quality data handling is restricted to
a simple level. If quality data validity is GOOD then the DATAVALID
output will be HIGH. If quality data validity is INVALID,
QUESTIONABLE, OVERFLOW, FAILURE or OLD DATA then the
DATAVALID output will be LOW.
