OPC Visual Basic - cant see plc

[AmerK]

Hi,

i'm using SoMachine opc server (CoDeSys) for modicon M238 PLC, and I want to create application in VB (2010 or 2012) but when i try to read tags in vb i cant see my plc i only see some PLC_id23. I was using opcsystem.net and QuickOPC.net in for communication with VB.

In other opc client (example: OFS client) i can see tags.

Can you post code that works and code that doesn't work?

You are really going to have to provide more info.
Or possibly source code.....

thank you both for reply, the problem wasn't in code.
In VB I couldn't see allias of PLC connected to OPC server, but on other opc clients i could see it.

I figure out that problem vas in .ini (settings.ini & OPCsettings.ini) for no reason OPCconfig.exe couldnt save my parametars for OPC server and PLC (example: my plc name vas "MyPLC" but in those files it was "PLC_id52" ) Then i manually edited those files and it all works.

Thank you guys.
