Does anyone have experience in programming Parent child alarms on ClearSCADA (Consequential) alarm.
I'm trying to suppress some alarms on our system.

Thanks in advance

Sure.
It's 'weird'.

So the Consequential Suppression system 'works' in ClearSCADA. But only for a limited subset of what other people might call works.
So,
Step 1) Configure Child Object to be Consequentially Suppressed by Parent Alarm (note, this is not by the Parent Object, but only by an Alarm)
Step 2) Generate Parent Alarm
Step 3) Try to generate Child Alarm, you will see that it does not generate... it is suppressed.

If the Child Alarm is reported as occurring before the Parent Alarm occurs... no suppression for you.
If you have a number of Parent Alarms that should all suppress the Child Alarm... umm, nope, not really an option here.

I have submitted a feature request for enhancement of the Alarm Suppression system (to allow some time ranges etc etc). But I can't find the SUP reference for it right now.
Schneider Tech Support should be able to find a reference for you though (just tell them Bevan sent you :P)
You might want to read what I wrote for it before asking to put your name as a +1 against it... but it might be useful to see what I wrote to get an appreciation for some of the limitations also...

Quick question does it have to be displayed in the banner in the suppression count be considered as working ?

Not sure I get what you mean.
The best way to check on the suppression is to look at the event journal for the child alarm. It should show that it's been suppressed.

There's a suppressed alarm count column in the alarm banner.
