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