Connecting to Kepware via OPC-UA Guide (5.4 and later)

Step 1: Configuring Ignition

2. Click “Create new OPC Server Connection…”
3. Choose “OPC-UA Connection” from the list of connection types.
4. If KEPServerEX is installed on the local machine use the actual IP address of the machine. Do not use localhost.

   If there are more than one items in this list named 'Ignition OPC-UA Client', delete all of them and wait for Ignition to recreate one. You may have to close this screen and reopen it.
