Tag properties

Each InTouch tag type has a set of properties that describe the characteristics of data associated with the tag. The four principal data types associated with InTouch tags are:

All tag properties are assigned initial values when you create a tag with the Tagname Dictionary. The following figure shows the properties of an I/O Integer tag.

After setting the initial values of tag properties from the Tagname Dictionary, you can dynamically change most tag properties using dotfields. A dotfield identifies a tag property that can be monitored or modified by a script when the InTouch application is running. You append the dotfield to the name of the tag in a script.
