Tags are JSup variables used to handle / exchange / store / process data. They hold a data of some type and can be used directly or in expressions in graphic object Animation or other JSup code.
Some system tags are always defined and not changeable, the others are created by the JSup application developer as necessary or imported by external systems.
A tag has many properties/attributes that define it:
- The domain it belongs to.
- The name: an unique name that identify it.
- The type, which determines the type of data the tag will hold.
- The tag class that determines many behaviours and properties of the tag.
- The alarm group that let you to group tag and their related alarms by physical or logical areas (or other kind of category).
- I/O hook(s) that connect the tag with some remote device item.
