SCADA – communicator – unable to browse

[nejcb]

Hello!

I am trying to set up tags with SCADA communicator but I am unable to. I can normally add and see tags with MatrikonOPC explorer, see and add tags in Matrikon OPC Simulation server, but not in Matrikon.OPC.Siemens. When I open device configuration and browse to PLC, click to “Data Block” i get eerror “Error browsing data items node: E_UNKNOWN_ITEM_NAME IOPCBrowse.Browse”. Please see the error –

I know I cannot browse tags, but I need an interface to add them to the SCADA communicator.

Thank you for help

Hello,

Does this error appear for any folder of the OPC server?
Could you try the same with Matrikon.OPC.Simulation server?

[nejcb]

Yes, it appears for any folder on the Matrikon OPC Siemens PLC server, but not on the Matrikon.OPC.Simulation. I can normally browse anything on Simulation server.

Do you have any suggestion what is wrong?

I think, you should try tuning DCOM configuration. How to open the config is described at the end of the article.

Also you can add items to the configuration file manually and watch whether it works or not.
File path: C:\SCADA\ScadaComm\Config\KpOpc_XXX.xml

I saw that suggestions with DCOM, but nothing helped. Now I got it working with entering points manually in configuration file. Thank you.
