Activate (allow) or inactivate (disallow)
blocking of the module/stage. This
parameter is only effective if a signal is
assigned to the corresponding global
protection parameter. If the signal becomes
true, those modules/stages are blocked that
are parameterized "ExBlo TripCmd

Meas Circuit
Superv Activates the use of the measuring circuit
supervision. In this case the module will be
blocked if a measuring circuit supervision
module (e.g. LOP, VTS) signals a disturbed
measuring circuit (e.g. caused by a fuse
failure).
Only available if "VX Source" ist set to
"calculated".
