OPC Server for AC800M V6 is Browsing Depricated?
Hi,
We create an application that interacts with OPC Server for AC800M V5 there we were able to get all OPC tags by the browsing function (Using Open OPC for Python). The newer V6 does not let the client brwse for all Tags.
Is there a possibility to allow browsing?
Why was it depricated?
Best Regards

AFAIK, AC800M OPC Server is only for internal ABB OPC clients. It is not supposed to be connected with external OPC clients. May be it was working in Version 5.x but it never intendent to do so.
You must use OPCDASurrogate OPC server that encapsulates all the OPC servers in 800xA and presents as a single interface to external OPC client. Only OPCSurragote is approved for external connection for 800xA data.
Which OPC server are you connecting to?
If you want only AC800M controller values, then you should be connecting to ABB.AC800MC_OpcDaServer.3.
Document 3BSE035983-600. AC800M OPC Server system version 6.0.
Hi !
I would guess it is a Windows security (DCOM/authentication) or a firewall issue.
There is a Windows service called "OpcEnum" that supports browsing of OPCservers, is it running (server-end)?
Good Luck!

Tho make the question clearer:
And appart from security reasons. The purpose is for internal testing purposes.
We connect to ABB.AC800MC_OpcDaServer.3
With V5:
it was possible to get all tags from a certain part of the opc tres i.e. ABB.AC800MC_OpcDaServer.3.Applications.TagsToScan.* --> then it returns a list with all tags below...
V6. Just responds with the tags on the same node of the branch... no recursive browsing.
