Browse Tags

After the device status changes to Connected, the Opto 22 groovEPIC and SNAP PAC Driver automatically discovers all variables and I/O points configured as Public in PAC Control.

You can browse these tags from either the Ignition Gateway or Ignition Designer.

Browse Tags in the Ignition Gateway​

  1. In the Ignition Gateway, navigate to OPC Client > OPC Quick Client.
  2. Expand Ignition OPC UA Server.
  3. Expand your configured Opto 22 device to browse the available tags.

Browse Tags in Ignition Designer​

  1. Open Ignition Designer.
  2. Select View > Panels > OPC Browser.
  3. Expand Ignition OPC UA Server.
  4. Expand your configured Opto 22 device to browse the available tags.

Troubleshooting​

If expected tags do not appear:

  • Verify the device status is Connected.
  • Confirm the PAC Control strategy is running on the controller.
  • Ensure the variables or I/O points are configured as Public in PAC Control.
  • Check that the controller is reachable on the network.
  • Review the Ignition Gateway logs (Status > Diagnostics > Logs) for communication or driver errors.
