The article says "Documentation & Rationalization of existing alarms"

If I have a plant that is out of control, what is the use of documenting and rationalizing the alarms that are causing it to go out of control.

Instead, I would think that you would want to take a broader look at the problem and document and rationalize the IO, and thereby creating alarms that are appropriate for the equipment and the operation. The difference being that my plant probably has the wrong alarms in the first place, so spending time documenting those would be like the overweight person documenting and explaining the nutritional value for the Super Sized Double Quarter Pounder with Cheese meal that they have every day at lunch. Perhaps it will steer them towards not having those every day, but what they really need is a salad and 20 minutes on the tread mill.

My thought is let's not document what is already broken and instead design and document what it should be. If the plant is in good shape, then sure, document what you have. But what you are describing above is something that is badly broken.

Or did I just misread what was written?

Anyway, just a thought.



>> ROLAND replies:

The PAS Documentation & Rationalization service does not just document the alarms as they are, but goes through the entire configuration of control system points and alarms to determine which points should have what level of alarm – basically a re-design of the alarm system.

Hope this helps clarify the posting!
