OPC DA2 driver - Ini file configuration [Citect Scada 2018 R2 ]

Rune

Hi,

I see in the driver help file that default OPC server is DA1.0, I would like to change to use OPC DA2.0. The "Ini" file parameter description help sections does not list the parameter 'UseOPC2', can I still just add it to the driver as shown below in the print screen? 

Thanks

Rune

  • Your second screenshot should work if the name of the IODevice (the name of the PLC, set in I/O Device configuration) in your project is "OPC_driver".
    The section should only contain the text OPC.

    However, this complex syntax is only needed if you have more than one PLC that uses the OPC protocol and you want to connect one or more PLCs using OPCv1 and other PLCs with OPCv2.

    If you have only one PLC, or all PLCs use OPCv2, you can use this simple syntax:
    Section: OPC
    Parameter: UseOPC2
    Value: 1
