ExBlo 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 Fc=active".

Rvs Blo Fc
Activate (allow) or inactivate (disallow) reverse 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
