View tag data
This section gives an overview of the graphic objects you can use to show tag data. For
information about setting up the objects, see Chapter 21 and Help.
The operator can view tag data at run time using these graphic objects:
Drawing object with horizontal
or vertical slider animation Control the value of a tag by dragging the slider object with a
mouse. The pixel position of the slider is translated into a value
that is written to the tag.
If the value of the tag is changed externally, the position of the
slider changes to reflect this.
Control list selector Select from a list of states for a process or operation. The list is
highlighted to show the current state, and the operator can scroll
through the list to select a different state. The value assigned to the
selected state is written to the tag.
If the value of the tag is changed externally, the position of the
highlight changes to reflect this.
ActiveX object A third-party object, connected to an analog, digital, or string tag,
including both HMI and data server tags. When the object’s
property value changes, the new value is written to the associated
tag.
