ABB.afwopcdasurrogate Process - OPC Comm v/s Data Direct

Hello,

We have 800xA 5.1 Fp4 system running with Redundant combined ASCS and also we have got one Information management server.

There are 2 excel reports running in IMS server, ABBGetOPCDASimple function used to retrieve data from 800xA system.

Recently we established Third-party OPC communication on IMS node (using Matrikon OPC Tunneller). And successfully communication established.

After OPC communication establishment, my reports started getting failed (Scheduler is aborting due to time out mentioned in scheduler).

When we tried to get only one value in fresh excel sheet using ABBgetOPCDAsimple function - its getting hanged. (throwing error/warning message - MS Excel is waiting for another application to complete an OLE action)

Then we tried to retrieve data using data direct Industrial IT process value - its getting hanged.

Tried to retrieve data through Test AIP client - also getting hanged.

Tried to access ABB.afwopcdasurrogate process through matrikon opc explorer - also getting hanged.

Through excel i am able to retrieve Historical values (ABBGETOPCHDA).

Excel not able to retrieve any data - is this because of opc communication ? (i guess both excel and opc communciation happens through surrogate process).

Does any one faced similar issue ?

Regards

Poorna

Sounds like the tunneler is blocking ADSS (the engine servicing Data Direct) OPC DA dataprovider.

Try this;

Search registry below HKLM\Software\ABB

(on 64-bit key name starts with SysWow64) for a key named something similar to "\OPCToolkit\...\UseSame" and set it to zero (0). Then restart OPC tunneler and ADSS OPC DA provider from ADSS Control Panel (in Windows control panel).

Now ADSS should spawn a separate surrogate process (AfwDsOpcSurrogate.exe in Task Manager).

If this does not work; please contact your regional ABB support center.
