LoopEdge DeviceHub Configuration

To configure DeviceHub for OPCUA, take these steps:

  1. DeviceHub > Add Device
    Type: OPCUA 
    Driver: OPCUA Client (Beta)



  2. Enter details specific to your environment and click Add Device.

    • Certain device drivers will not have a list of Register Names in the DeviceHub Add/Edit Tag form. These are Free Tag PLCs. For Free Tag requirements, see Troubleshoot Device Connectivity Status.
    • For the Register Name, in the DeviceHub Add/Edit Tag form, map the OPC server tags to the client using this format, where the semicolon is significant: ns=1;s=tagname
      • Example: ns=2;s=Channel1.Device1.Tag1
    • Only Anonymous security mode is supported.
    • Server Name currently is not used, however, an entry must be made in this field.
