To All,
I again, want to encourage list members to use the Foxboro
Documentation available online at:
http://ips.csc.invensys.com/
if at all possible. This is a great source of information from "The Horses
Mouth". If it doesn't give you the answers or you can't find what you are
looking for contact them at:

Recognizing that it is possible that many of you may not have access
to their website, I am including an example of a working Common Alarm Group
(CAG) Configuration File from our system. As mentioned in the previous
note, you must reboot affected workstations for changes to take effect. In
this case, the commgrp.cfg file would need to be copied to 04WP02-4 and all
3 workstations would need to be rebooted!! In the example below 04WP03
would be able to ACK, CLEAR ALARMS, SILENCE HORN for both 04WP02 and 04WP04
because it is a member of both groups. 04WP02 could do the same but only
with alarms in common with 04WP03, not 04WP04. 04WP04 could do the same but
only with alarms in common with 04WP03, not 04WP02. It should also be
understood that Compound Group Devices must be configured to send alarms to
all WP's in the same CAG group. In the example below for CELL1G1CAG
Compounds would need to send to 04WP02 "AND" 04WP03. For CELL1G2CAG,
Compounds would need to send to 04WP03 "AND" 04WP04. One problem with this
configuration is that picking the "Alarm" on top menu bar of a DM or Foxview
opens the Alarm Manager and issues a "Horn Silence" to both CAG Group WP's.
In the configuration below, a pick from 04WP03 silences the horns on both
04WP02 and 04WP04. That may or may not be desireable.
Example of CAG File
# Common Alarm Group (CAG) Configuration File
#
# (CAD Redirection)
# WP CAG Backup BLK TOP USER CAG
# LBUG NAME1 LBUG DTL PRIO DISP NAME2
04WP02 CELL1G1CAG ------ ------ ------ ------ ------------
04WP03 CELL1G1CAG ------ ------ ------ ------ CELL1G2CAG
04WP04 ------------ ------ ------ ------ ------ CELL1G2CAG
Below are excerpts copied directly from Foxboro's website as an example of
the information available there.
Workstation Alarm Management - Foxboro Document (B0193RV)Rev D
Section 2. Alarm Subsystem
Configuring Common Alarm Groups
You must initially run /usr/fox/alarms/CAGinit to create the configuration
file for CAGs (/usr/fox/alarm/commgrp.cfg).
To run CAGinit
Type:
cd /usr/fox/alarms (on a UNIX workstation)
cd \usr\fox\alarms (on a Windows NT workstation)
Type:
CAGinit (on a UNIX workstation)
sh CAGinit.ksh (on a Windows NT workstation)
The commgrp.cfg file then contains a list of all workstations throughout the
system and the information for these capabilities:
CAG-related common horn silence
CAG-related common horn mute
CAG-related alarm clear (using the CLR ALM button)
Workstation alarm recovery
Process display call-up
----------------------------------------------------------------------------
----
NOTE: A workstation need not be a member of a Common Alarm Group to
configure WP alarm backup or process display call-up.
----------------------------------------------------------------------------
----
The following information may be optionally configured for every workstation
listed in the configuration file:
The name of the CAG with which the workstation is associated.
The name of a second CAG with which the workstation is associated.
The letterbug of a backup workstation from which to recover the current
alarm list and annunciator panel LED settings, should a reboot be required.
(Reboot clears alarm information.)
The names of DMs to which the following alarm displays may be redirected
when accessed from an alarm display: Block Detail Display, top priority
alarm display, and user display.
Each workstation's alarm alert database initially contains default
attributes. These attribute in the init.user file that affects Common Alarm
Groups is:
Attribute Default
Clear alarm button option (CLR_OPT) Clear the alarm from the database only
on the workstation initiating the action. The associated annunciator light
or any control block is unaffected.

When last I used them, the edits to commgrp.cfg did exactly
what you describe. Don't forget that both stations need a
reboot to 'install' the edits, though.

Subject: [foxboro] Annunciator Keyboards - CAG
hey List...
I have 2 WPs (51) with 1 annunciators keyboards each...and I'm trying to
operate them as one...
I mean, when an alarm arises, the horn is activated, and I want to be able
to mute both of them when I acknowledge it (or press silence bouton).
I've been told that CAGinit, and editting commgrp.cfg with group definition,
does the job...
but it's not working.
Does someone have a solution for this...
thanks in advance
