IEC61850 to Areva relays fails after 800xA upgrade
We have recently upgraded an old 800xA system (2010) from version 5.1-0 to 18.104.22.168.
The IEC61850 server is upgraded from version 1.1.2 ALPHA 4, Build 3 to version 6.0.3 (with roll-up 5 and TC15).
From the server (redundant pair), we had communication to some P139 relays.
After the upgrade, we still have connection to all the relays, but the values are not updated continuously, meaning that they are only updated when asked for by the server (refresh, opening of faceplate etc.).
An investigation of the setup shows, that no are assigned to the server. This was also the case before the upgrade, but how it could work before is a mystery for me. Sadly the guys that did the configuration in 2010 is not here anymore, so I can't get input for how/why it was done like this.
In order to get it to work, I assigned the to both of the servers, resulting in a loss of communication to all relays. This because of there is only 1 client allowed per .
If the redundant server is disabled, I have connection to some of the relays, and the values from these are updated correctly. Though some of the relays apparently don't allow the server to read it's .
The last try was to only poll for the signals, and not read the , but strangely polling is not working at all.
Maybe it's a long shut, but hopefully somebody has experienced this or not a thing or two about upgrade problems or relays, so the following questions can be answered:
- How could the IEC61850 communication on the old system work without having any assigned to the servers?
- Can the upgraded system communicate with continuously updating signals without reading the and poll for the signals? If yes, are their specific parameters that needs to be set?
I've attached a .zip file with the . and . files, in case you want to look at those.
In advance thanks a lot for any answers, it is much appreciated!
We have faced similar issues while working with 800xA 5.1 RevA systems.
The solution to this problem is that you need to add RCB's and their Clients in the icd files and create a fresh scd file. We use IET600 tool for the purpose.
This scd file you can upload in OPC server. The Areva relays must also be written with the new icd/scd files so that they get updated with the RCB's and their clients. In case you have redundant servers, you need to add two Clients for each RCB's.
And I do not see the .pcmp/.icd files here as mentioned by you.
Revert for further clarifications.
