How to Edit an Existing UDT
If you make a change to a UDT, all your instances will automatically get updated because they are all of the same UDT type.
To make a change to your Motor UDT, go to the Tag Browser and double click on Motor. This example adds a new Memory Tag.
The Tag Editor will open. Click on the green + button on the top-left of window, and select New Memory Tag.
Configure the following properties:
Data Type: String
Now, each instance automatically gets the new Memory Tag. Expand each of your Motor Tags to see the new MotorType.
You can make rapid work of making changes to instances using a UDT.
