function in a system, that is, either in a complete delivery system as an acceptance test (FAT/
SAT) or as parts of that system.

If a block/unblock command is sent from remote to function, while the IED is
shut down, this command will not be recognized after the start up, thus the
command that was sent prior to the shut down is used. In such cases, where
there is a mismatch, the user is advised to make a complete cycle of block/
unblock operations to align the statuses.
