Alarm cannot acknowledged, or Can not sync the Red. CS.
Hi.
We have a 2 oo 3 Aspect and 4 connectivity servers.
Separate the 2 project.
2 CS servers are parallel redundany.
Problem is alarm cannot sync the red. servers.
Please check the attached file.

Additionally, verify that Event Collectors within a redundant OPC server pair SHARE same service group.
With two pairs of CS I assume you have two Control Networks, or have split one large over an extra pair of servers for load sharing, security, etc purposes?
Services
- Event Collector
-- Service Group AC 800 Net 1
--- CS1A
--- CS1B
-- Service Group AC 800 Net 2
--- CS2A
--- CS2B
- OPC DA Connector
-- Service Group AC 800 Net 1
--- CS1A
--- CS1B
-- Service Group AC 800 Net 2
--- CS2A
--- CS2B
Given the above service config, "1" and "2" servers shall NOT connect same AC 800M CPUs.

I assume you noticed the E_INVALIDARG return code in the Acknowledges log.
For AC 800M OPC server to grant acknowledge the alarm's state must be "unacknowledged" and a number of the passed parameters MUST match:
- EventTime
- SrcName
- ConditionName
- Cookie (a serial number)
Cross check the contents of the HMI vs OPC server.
- Use "DumpAlarm" operation on the Alarm Manager.
- Dump OPC server content as you have done already, or use a 3rd party OPC AE client.
Are they in sync?
The AC 800M Alarm Collector config in the 800xA HMI must have the "Support Refresh" feature enabled. This is important, or else sync issues may arise.
Sometimes you need to restart OPC server and/or cold restart the controller.
Ask regional ABB support center to open a support case if you can not figure out what has gone wrong (and fix it by yourself)
This my configuration.
