5.7.2 Control blocking example
The physical outputs to process can be blocked with “Blocked” mode. If physical
outputs need to be blocked, the application configuration must block the signals or the
function blocks that affect primary apparatuses. The blocking scheme needs to use
BEH_BLK output of Control function block.
