# Add OPC Tags to a Job File

Although every In-Sight vision system that supports OPC UA has predefined System Tags for use by OPC UA clients, these tags most likely do not expose everything you would like to access from the OPC UA client. For this reason, you can add a Job A job is a user-configured program in In-Sight 3D EasyBuilder consisting of functions and designed for specific applications. You can create and edit jobs using the In-Sight 3D EasyBuilder interface, and load them on a vision system for deployment in a live environment. Tag to any non-empty In-Sight 3D EasyBuilder cell so the value in that cell becomes available to the client.

1. Log on to a vision system and load the job file you want to use.
   Note:

   OPC Tag names cannot be equal to any of the predefined System Tag names used by the In-Sight OPC UA Server.

2. Name the cell to publish the Symbolic Tag.

3. The Symbolic Tag has now been associated with the named cell.

   Note: The cell now has a blue triangle in the lower-right corner as a visible indicator that the cell has a Symbolic tag. If you hover over the cell with the mouse, notice that the Symbolic Tag name is displayed in a tool tip. This symbolic tag name is the Job Tag name displayed in the OPC UA client.

4. Once you load the camera with the updated job by going online, the OPC software discovers the tags.
