Re: [foxboro] alarm inhibiting vs. alarm disabling - process summary reporter

My daughter wanted the following for her 16th birthday (last year):

1) A car
2) A trip to France
3) A pony

She got:

1) A 1990 Toyota Camry Stationwagon with about 120K miles on it
2) An exchange trip with classes 8 hours a day for three weeks to Nice
3) A 1/2 lease on a horse at her barn that requires her to be there 3
days a week taking care of the hay burner.


There are several morals to the story:

1) Be careful what you pray for, you may get it. Pray for strength=20
   and you'll get opportunities that test your strength and build it.
2) Project requirement definition is very important.
3) Things often sound better (more glamourous) than they are:=20
   "I got a car, a pony, and a trip to France for my 16th birthday!"

Merry Christmas. I've got shopping to do.

Me!

Going beyond that, I'd like to see a comprehensive alarm management
mechanism incorporating flood suppression, grouping, and other
techniques, built in to all I/A blocks that are capable of generating
alarms, so that we don't have to roll our own with scripts that are
difficult to develop and maintain. =3D20

I also want a 60" Plasma TV with a surround sound system for Christmas.
And a pony.

Hmmm....sounds familiar :)


So let's take a poll: who would like to see connectable alarm
destination=3D20
group (*GP) parameters?

Good one Michael,
The annoying thing that I find is that as soon as you
use INHIB or INHALM to configure logically driven alarm suppresion the
block automatically appears as "inhibited" on the inhibited alarms
report. What I have done is to use INHALM for logically supressing
alarms, so that the operators can still overide the logical inhibits by
using INHIB. I have walked away from the Foxboro inhibited alarms
reports and used a script which looks for INHIB =3D3D3D1, and combined =3D
with
another script which extracts alarm inhibiting actions from the operator
action logs. This gives me a time stamp of when an alarm was operator
inhibited. The other annoying thing is as part of my overall alarm
philosopy I want to reduce alarm traffic to the operator during abnormal
situations. There is important data which can be used in post event
analysis which would be lost if a blanket inhibit of non immediately
important alarms are suppressed, so I have a desire to divert many
alarms to an "historian only" alarm group. This would be easy to do if
the alarm group paramaters on any block which produces alarms was
connectable, but....(hope Alex is looking!). At the moment what I am
doing is run two blocks, one for the operators, and one for historian,
and use block names which are as close as possible to each other.
regards,
Alan  =3D3D20

You can also toggle the HEX bits individually from block detail in
Select. For example, to inhibit only the HI alarm, 1. Call up block
detail for the AIN. 2. Click Alarms 3. From Select pick the HIABS
parameter. 4. Click Toggle

A black INHIBITED should appear indicating that the HEX bit to disable
HIABS has been set.
