Configure tags

InTouch HMI applications use tag values and properties to visualize values, store, and retrieve information about the process and the state of the process. For example, tags are used to receive values coming from field devices and to send commands and set points to the field device.

Tags can be used to visualize the present value, and past value, and to control a process by changing a set point through these tags.

In this simple application, tag data will be shown and used to set the state of the graphics that represent the equipment of the mixer.

Create the following tags for the Mixers application using the procedure provided in this topic.
