Question details

Alarm not working for NEW created object on the system or edited

I was troubleshooting on a running DCIM system which having issue on alarm. Most of the alarm in the system is configure with Alarm Expression which map to Expression code on Control Connection OPC Properties data.
Existing object alarm is working fine and I did checked all Afw services Connection Status in GREEN.

It was not working on new create object alarm, I was then try to "Override" the Alarm Expression from a single working object which the alarm is working. The weird thing is the alarm of the "Override" object was then not working anymore. I was then try to release by "Delete Override" on the Alarm Expression, and it remain not working after all. This is really something abnormal...

I did tried to restore the backup to a virtual machine and setting all the services to run "Strictly Local" and all alarm is working fine...

Is there a limit for Soft Alarm?? Will it be services problem?? This is a running system which I am not allow to simply restart on the Aspect System for try an error...

You are likely suffering from an overloaded SoftAlarm Service / Property Translation function.

There are no finite numbers I can convey; the maximum possible expression based alarm conditions is depending on a number of factors, not only "number of Alarm Expression aspects" and "number of alarm conditions within those expressions". CPU and memory are also restricting factors.

Reducing the total number of expression conditions, less OPC properties, less complex translations and applying more CPU GHz have been successful in other cases.

Please make sure you do not have any constantly written/updated General Properties; this can be monitored on the Aspect Directory's Statistics objects in the Service Structure. There should NOT be constant transactions ongoing; the typical reason to see never a zero number is improper use of General Properties (e.g. as targets of Property Transfer)


Please speak with the body / entity delivering the system to you.

Hi Stefan,

Great thanks on your advise. I cannot paste image by comment on your reply so I create new answer under my question.
I cant really find the Statistics Objects that you describe above. Below from the Service Provider Status from Aspect Directory:


And I did check on the C Drive usage as below:


Please help.

Regards,
Michelle

Transaction rate look OK if I recall the algorithm correct (I’m on vacation unable to verify): 0.0001165 * 86400 equals 10 transactions the previous 24 hours.

The symtoms you describe deserves a professional examination. Please get in contact with the delivery project or their organisation to obtain assistance.

Overload in soft alarm is unfortunately something we commonly notice in Datacenter applications. The final application design must heed available computation resources.

Hi Stefan,

Will it be the reason because they adding more and more inactive node to the system? As I found the engineer is upgrading the system by adding several new node.

As refer with your reference, it can verify that at least this is not the CPU problem.
Sorry to bother you during your vacation, I was trying hard to get any relate from project deliver team as too many parties was involved on this system past 3 years (MYABB, INOPC, 3rd party SI).
Currently this system is upgrading from another third party SI (not ABB) and found this issue. I will ask them to remove those inactive node first.

Adding more computers is likely not the reason.

What counts (but not limited to) is:
- The total number of Alarm Expression aspects
- The total number of Conditions embedded in these AE aspects
- The expression syntax used to compute the state of these Conditions
- The number of OPC DA properties in use by AE
- The speed by which the source OPC DA servers can deliver data to the expressions
- The CPU speed and available resources in the computers hosting the SoftAlarm feature
- The Modus Operandi of engineering (inheritance, use of override, etc.)

Please file a complaint with the body/entity delivering the system to you.

Many thanks on guide and advise Stefan!

Sorry for confusion, the inactive node I mean the tag that they added for the Kepware OPC communication.
I created an Event list in Services and found Failed to collect a lot of logs due to the inactive tag.
Event also shows the Soft Alarms Service Provider left and reached in some how.

Please remove of deactivate Log Configurations on Properties out of service. However, this will not improve the SoftAlarm problem, merely clear the System Event List and make it more useful.

What remains after clearing out the Basic History events?

In particular, from SoftAlarm and Kepware?

I recommend using the following two event lists that both reside on the [Workplace Structure]Web System Workplace object:
- System Event List
- Operator Message List (actually, its OPC DA events you see here)

Do you get ”Poll Timeout” events? Such indicate deadlocks or severe overload/resource exhaution leading to an automatic ”kill & restart” of the indicated service.

[Workplace Structure]Web System Workplace object:
- System Event List
I checked back on the SoftAlarm left and reached service state below with attached Event Detail as updated Event list mostly showing Messanger Device Info and Failed to collect logs...


- Enter Synchronize State due to failure condition.


- Service Provider left service state



2) Operator Message List - OPC DA events
