Hello Fabio,

I've quickly checked the zip file attached to this thread.

1) I only see "OnDataChange", i.e. OPC server sending updates to active subscription.

2) I count 15684 OnDataChange. Most items seem subscribed twice?

Line 8: CConnector::OnDataChange - data: item(936448), quality(c0), 7/28/2016 9:10:29 AM, value(VT_R4) = 40.9144
Line 18: CConnector::OnDataChange - data: item(38656), quality(c0), 7/28/2016 9:10:29 AM, value(VT_R4) = 40.9144
Line 28: CConnector::OnDataChange - data: item(38144), quality(c0), 7/28/2016 9:10:31 AM, value(VT_R4) = 60.1852
Line 38: CConnector::OnDataChange - data: item(935936), quality(c0), 7/28/2016 9:10:31 AM, value(VT_R4) = 60.1852

3) 5526 updates have GOOD quality (c0)

4) 10000+ updates have BAD quality (18, 20, etc)

I see no evidence of "refresh", etc. and frankly speaking I doubt it to origin within the process graphics layers of 800xA.

Can it be the tunneller itself performing the refresh? Can you try with another tunneller?

I will be back in office in two weeks from now, can you send me an email and we can continue with this through a regular support case?

I guess you should file a case with regional support (Italy -> DE L3 in Minden).

Hello Stefan,
i already opened a SL case: # ABB2016072800013.
Unfortunately i think i've to fix it before you come back.
Thanks for your support.

OK.
I did not have time to cross reference between the Matrikon log and the AppLog.
I suggest simultaneous logging while performing minimal, but well documented actions in 800xA. All other subscriptions through tunnel should be stopped while performing this.

Comparing actions made in 800xA with logging in Matrikon and AppLog should tell if refresh, etc origin in 800xA or in tunneller itself.

Hello,
Without the tunneller the communication is working fine.
So it is not an 800xA issue...

Other Question:
When the OPCServer is down the service provider goes in "error" status and doesn't try to reconnect itself anymore.
I remember that in such cases the status should be "undefined". Isn't? Which is the difference? Tks

What error code do you get in afwservicestatus.exe? Error state require manual intervention (disable/enable).

Undefined occur (afaik) only when service is intentionally disabled (on service, group or provider level)

State is: error

I'm out of office, can you translate that with afwerrorlookup.exe (onboard 800xA) and add the text here as a comment?

E_AFW_OADP_INVALID_CLSID
The OPC server class ID is not valid

Unable to verify with R&D at the moment but here is my estimate of receiving 8ABB1440:

800xA OPC DA Connector "expects" the OPC server (CLSID) configured to be constantly available. Connector will (if enabled) keep connection with the CLSID, or wait in "Synchronizing" state until OPC_STATUS_RUNNING is exposed by server (Connector then assume Service state and accept clients).

If CLSID is removed, it is considered a fatal, nonrecoverable error. The Connector will then fault itself with 8ABB1440 and wait for system administrator to fix the OPC server (CLSID) problem.

I believe Matrikon tunneller can issue several parallel tunnels, each with unique CLSID. However, 800xA can not automatically recover when a CLSID is temporarily removed and recreated, something I suspect can happen while working with the tunneller configuration or user interface.

I've removed the tunneller.
Now the 800xA is direrctly connected to the end OPCServer (WinCC) via DCOM.

OK
Maybe a problem with DCOM then?
I suspect that 8ABB1440 is received when CLSID is unavailable and for that there is currently no "retry until success" function made/available.
