Templates are a simple but a very powerful feature in Ignition that you can use with the Vision windows. The power comes from the ability to modify only the template in one location while affecting all of the instances used throughout the project.

HMI and SCADA systems typically have a lot of repetitions in their screens. You might use a group of the same components over and over within your project. The data driving each set of graphics is different, but the graphics themselves are copies of each other. You can make a single template and use instances of the template over and over again.
