John,
Is this what you want to do?
The PATALM block compares the logical combination of up to 16 Boolean inputs
to a user-specified 16-bit pattern. For a pattern match, an alarm message is
generated and a match indicator is set. A state name and message text can be
assigned to the alarmed point as part of the alarm message. The pattern
match indicator can be connected to other blocks or into control schemes.
Standard Features
* Manual/Auto control of outputs
* Up to 16 Boolean inputs
* Alarm message or pattern match
Optional Feature
* State name and message text are both part of the alarm message

> Subject: Can alarms be grouped to give a single alarm?
>
> I would like to know if alarms from different blocks can be grouped

>
> For example, a pump stops working. I could get a pump status alarm,
> a
> lo flow alarm, a hi output alarm, and a hi level alarm. All of these
>
> alarms represent one condition. Is there anyway to make these give
> just one alarm without using logic blocks all over the place?
>
> Or, if logic blocks are the only way, what is the most efficient way
> to accomplish it?
>
> Or, should I just consider getting rid of some of those alarms?
>
> I looked in B0193RV - Workstation Alarm Management, but didn't see
> anything obvious.
