OPC browsing error (ABB OPC Client and Matrikon)
I am working on a System to a SV6.0.3 version and I got a problem trying to browse the OPC data.
Our system 800xA 6.0.3 is installed and working OK, but it is not possible to browse Control Structure because we receive an error.
The browse function was tested with ABB OPC Client software and Matrikon Explorer software. Please check attached files.
There is a product bulletin : “System 800xA Browsing Error in External 3rd Party OPC Explorer while connected to AfwDSOPCSurrogate and/or AfwOPCDA Server”. But it refers to another system version.
We have read that this happened before in large structures like in this case but there is no information over there about a workaround to this problem.
We tried the solution proposed in the bulletin and also running the OPC Client Software in different nodes, but no success on browsing the tree.

Strange, I assume you have verified that all Alarm List and Event List aspects on the object where browsing fail? It just takes one corrupt list to put you in trouble.
Deletion of referenced Alarm and Event List Configuration objects is actively prevented, but you can still ”create” this problem by importing an ”orphan” list from AFW.
I assume the Consistency Check tool will detect a corrupt list as well.
