Can I use protocol KNX in LabVIEW?


While there is no specific Communication API for KNX in LabVIEW, you can use OPC Servers to connect with your device.  The OPC Foundation has released three major versions of the OPC specification. LabVIEW currently supports the following versions of the OPC DA Specification:


  • Version 1.0—DataSocket Client.
  • Version 2.x—DataSocket Client, Variable Engine OPC Server, (DSC Module) DSC OPC Client.
  • Version 3.0—Variable Engine OPC Server, (DSC Module) DSC OPC Client.


If you look up the OPC foundation site you will find that this server uses DA 2.0. So you should be able to access it using Datasockets or DSC.
