outputs (primarily function blocks of function block groups
CONTROL and COMPARATORS) are set to logical 0.
Fault S Severe Fault

outputs go to safe state

Remedy cause of fault to ensure that
system continues operating regularly. Then acknowledge fault
message after input of parameter or configuration password.
