In our plant we have settled an analisis group to analize all the =
"posible"
alarms when the plant shuts down. Now we have tables with signals to =
change
their priorities to 5 based on Interlocks contitions. The CADs will =
have a
filter to hide priority 5 alarms. So when an interlock trips all the
asosiated alarms change their priorities to 5 and when it is reseted =
alarms
return to their original state. We choose to change priorities insteed =
of
inhibit them because we need alarms to know what is going on when some
equipment doesn=B4t start.=20
