Tim,
Good job! I saw your e-mail after sending my response. You can configure
the buttons to execute multiple commands so you should be able to do the
job with a match, clear_page, and stop_match all on one button.

Steve,
You'll probably be hearing soon from Kathy Grace when she gets back from
vacation (she's the #1 resource on ADMC), but what it sounds like you
want to do is use the filter functions of the Alarm Manager.
In the Alarm Manager, you'll want to click on View..Match Alarms. For
the scenario you mentioned in your e-mail, you would check the boxes in
the Priority section for 2, 3, 4, and 5. Then click on Save.. to create
a .ams file (alarm spec file). This gets saved in
/usr/fox/customer/alarms/amspec. =3D20
The next thing you would do is create a button on the Alarm Manager that
invokes this filter, and another one that clears it. Personally, I
would do it by editing the am_def.cfg text file, but the preferred
Foxboro method is to use ADMC. B0193RV does a pretty decent job of
walking you through the various menu options and how to do various
tasks. When you build the buttons, you are looking for adding the
"match" command and the "stop_match" to the buttons. The only argument
for the match command is a filename of what to match against. This
would be the .ams file you created earlier. I think you need to use the
full path name for this file. There is no argument for the "stop_match"
command.
So, when you get it all done, you have 2 new buttons, one that says
"Show Only Pri 2-5 Alarms", or something like that and the other that
says "Show All Alarms". The operator would click on the first button,
and then the Alarm Manager would only show Priority 2-5 alarms, and then
he could use the "Clear Alarm" and "Clear Page" buttons to clear the
alarms that fit the filter. When he's done, he could click the "Show
All Alarms" button to get the Priority 1's back.
It's more steps than you probably want the operator to have to take, and
it's not at all idiot-proof, but that's one relatively simple way to
accomplish your goal. You could probably invoke other commands with the
new buttons that change the Operator's access level only while the match
is active so that the Clear buttons are only active when the filter is
in effect, and not active when it isn't. I'll let you play with that. I
am not aware of any way to make the Clear Alarm and Clear Page commands
do anything other than exactly what they say.

Subject: [foxboro] changing clear button action in CAD
I have been trudging through the documentation around alarming and
haven't quite found what I need.
I want to change the "Clear Alarm" and "Clear Page" button actions in
the CAD. Instead of simply disabling these buttons, I'd like to be able
to have these buttons ignore alarms based upon priority. For example, I
don't want priority 1 alarms to be cleared, but all others can. B0193RV
taunts me with a "hint" that this can be accomplished, but I haven't
been able to discover how.
Hopefully someone knows how to do this (on a UNIX-only system). Thanks!
Steve Shimp
