System tags store information generated while the system is running, such as the name of the logged-in user, system time and date, and the like. FactoryTalk View creates system tags when you create an application. The system tags are stored in the folder called system in the HMI tag database, and their data source is system. You can use system tags anywhere you would use any other type of tag, but cannot create or edit them. For example, you can create a string display object on a graphic display and assign the system tag, system\Time, to the object. At run time, the object shows the information stored in the system tag, which is the current system time.
Open the system folder in the Tags editor to see the system tags.
System tags provide the following types of information:
About system alarms and time tags
About system graphics and user tags
