Do you have Netsight Manager?
If you configure the traps, you can also configure scripts to be executed when
a trap is triggered (ie. link down) and switch an alarm block for the switch.
That will turn up in the process alarms *CAD*.
That is only for the switches case.
Remember that in some cases the switches reboot faster or a link goes down/up
faster than the device monitor takes to declare it failed. So you might have
switches problems and they are not even recorded on smon (or Foxray for that
matter). Thats why Netsight is useful.

Hi list,
I/A 8.7 with ZCP/FCP270
We've had an issue recently with a redundant A2 Mesh switch
going down, causing a network burst 5 hours later. Our plant
was "blind" for some 20min due to this event. Luckily no
losses or damages. Invensys service responded very fast,
providing a replacement switch, and everything was soon back
to normal.
Now for my question:
Our control room operator didn't notice the red blinking sys
button because it's blinking most of the time. (we have some
time synch errors on profibus FBM's which we can't
find any solution for). Off course in the ideal world no
system alarms are generated, but a 20 yr old plant isn't
exactly the ideal world....
Invensys doesn't really make any distinction between system
alarms, yet some of them are "harmless" and some require
immediate action.
I can use a query in foxray to filter on "SYSMON -00043
Equipment failed" or something similar and send an email to
engineering, but this is useless outside office hours. I can
buy some fancy cell phone messing stuff or I need to find a
way to tell the control room operator to call engineering
when a certain system alarm exists. I prefer the latter, but
basic I/A doesn't have anything which can do that it seems.
I'm currently checking to see if I can have our Cisco Call
manager, which has a sim box connected to it, to
forward a mail as an SMS to a designated cell phone number,
but no idea yet if this will work.
How are you handling this?
Thanks & Rgds,
Dirk
