Re: [foxboro] Alarming inconsistencies

Thanks to Neil and Jim!

I implemented both of their suggestions and the alarming is working
properly again.  I know I had effectively done these steps earlier, but
apparently that was prior to running dm_recon on the AW.  It seems
awfully elementary, but I have to wonder why it is necessary.  If I can
see that the parameter is what I want it to be, why doesn't it work like
I expect it to?  I suppose that is just asking too much.

For what it is worth, I suspect that the problem originated when the
entire facility in which the test system now resides (the administration
building) had a power outage the middle of last week.  It appears that
the device master was somehow switched to a P92 box that is connected to
the nodebus which we use as a backup historian for our live system.

Subject: [foxboro] Alarming inconsistencies

We have a test system set up and recently had to relocate the whole kit
and caboodle.  Once the WPs were up and running, I noticed some odd
behavior with the alarming.  Our service engineer recommended that I run

 

dm_recon t

dm_recon d

dm_recon

 

on the AW which helped quite a bit, but there is still a problem I
haven't been able to clear up so I thought I would toss it out to the
group.

 

The system is a bunch of CP60's hosted by a P80.  The WPs are P81's and
P79's.  We are running I/A 7.1.4 with FV 9.0.3.

 

In two different CPs I have similar compounds that contain station
blocks with essentially identical definitions, i.e. group 4 has the same
set of devices defined and the same hex value for selecting which
devices from group 4 for alarm notification.  Within the two compounds I
have essentially the same AIN block with the same alarm limits.  Both of
the blocks are in alarm but only one of them is distributed to all of
the selected devices in group 4.  The other block is sent to a few of
the devices (printer and one of the WPs) but not all of them (AW and
other WPs) - or at least it doesn't show up on any of the AM displays.
I know that there are other blocks in other compounds and other CPs that
exhibit similar behavior, but with a differing set of devices their
alarms show up on (though group 4 and hex value are all identical).
There is one WP they all seem to reach and they all show up on LP01 of
the AW.

 

Any ideas about how to make alarms go to the selected devices?

 

Thanks
