Re: RE: Can alarms be grouped to give a single alarm?
Jack, In a similar vein, if you have alarms that are less important when the pump (or other piece of key equipment) is down you can connect the alarm priority -- ie. gland seal is a priority 1 alarm when the pump is running, but a priority 5 alarm when the pump is off. You can also use the alarm inhibit mask to selectively inhibit alarms -- ie. pump box level hi-hi is never inhibited, but hi, lo, and lo-lo are inhibited when pump is not running.

Hi Jack, what about inhibiting the flowon alarms? Like when the pump stops you inhibit the low flow etc with the pump status bit or so. We here at NZSteel are implementing, where ever we can, an alarm inhibit scheme to the extent that halve a plant could be inhibited when appropriate. You have to think of a smart scheme of lifting the inhibit without regenerating nuisance alarms. There is nothing worse than nuisance alarms from equipment that is turned off or being started. I've found that, with a lot of input from operators, you can set up a really good working alarm inhibit scheme. Cheers, Frits Schouten.

RE: Can alarms be grouped to give a single alarm?
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 Harry W.
