9011 Alarm Cause From PQ Meter

[kunwoolee]

A. There is a problem with Company G's installed PM8240 and ION9000.
1) 1) Alarm 9011 occurs on installed meters (300 units).
2) 2) After the alarm occurs, the product reboots.

B. Expected Cause
1) We changed the system from PME to PO 3 months ago. I added reset function through Modbus Writing in PO.  (Modbus write: 0,1,0,1 alternately every 2 seconds)
2) The problem of phenomenon A is constantly occurring.
3) I removed the Modbus Writing function every 2 seconds 7 days ago.
4) No A phenomenon occurred on the meter installed for 7 days. Previously, four to five alerts were issued every day.

C.Identify the cause of the problem
1) Can the PQ meter be problematic if the Modbus Writing function is used every 2 seconds in the PO?

The problem has become serious, so the client company is considering not using the Schneider meter.

Hello @kunwoolee , strongly, strongly recommend contacting technical support to start a case to troubleshoot this. Would need to collect more information before we could say much of anything. Would need to know so many more details (include with case to tech support). What registers are you writing to, what value are you writing to the registers. How is the meter configured (template of meter and well as configuration report).

This is not a case I would suggest trying to troubleshoot more on the forums.

Regards,

Charles
