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.

Incoming data with q=oldData 0 0 1 0

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 (if
easy GOOSE engineering is enabled) to receive the binary single
point values.
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.
