# Enable the OPC UA Server

If using OPC UA, you must first enable the In-Sight OPC UA Server on the vision system and then connect to it from the OPC UA client.

1. Start up the In-Sight Vision Suite.

2. Select a vision system and click Industrial Ethernet utility on the Home Screen. The Industrial Ethernet Configuration dialog pops up.

3. In the Industrial Ethernet Configuration dialog, check the Enable OPC UA Server checkbox.

4. Click OK.

5. When prompted, click Yes to reboot the vision system. Once rebooted, the OPC UA server is initialized and the discovery endpoint listens for OPC UA client requests.

6. Launch the OPC UA client.

7. From the OPC UA client, you must enter the endpoint URL to connect to the OPC UA server. The endpoint URL must be in the following format, where <IP Address> is the IP address of the vision system: opc.tcp://<IP Address>:4840 For example: opc.tcp://192.168.0.8:4840.

Note: You can establish a maximum of two client connections at the same time.
