You can right-click on the representation of the tag on the screen to open a context menu. From that menu you can edit the properties of the associated tag to correct such things as I/O addresses and scaling values. If you have a tag that references another tag, such as a custom motor that refers to digital inputs and outputs, you can "drill down" to these component tags simply by clicking on the tag name within the configuration dialog box for the motor. This will allow you to view and edit the parameters for the referenced tag. All this is done without ever stopping the application.
