I'm more a language programmer than a PLC developer so I'm a bit lost in all this stuff...
Is the OPC server part provided by every manufacturer or is it something you may need to buy/program?
If OPC standardizes, does it mean an OPC client could communicate with any OPC compliant server?
Is there any source code in VB6 for programming a OPC client (free of charge)? I just want to dump some of the PLC values to a database using the VB6 program.
