MultiTagViewer - Advanced Object

Description

The MultiTagViewer Object (MTV) was designed to display data from different types of tags mostly used to display arrays of data types or simple arrays.  It can be used to visualize all index values of a float array or if the tag is a Data Type, it will be possible to add columns for all members of that Data Type.

Tip1:  It is not possible to add information from 2 different tags.

Tip2:  Screen tags, such as #var, can be used to configure a MultiTagViewer but its type must be different than generic.

The configuration is very simple.  The user must open the Properties Window and define the Tag, Columns and appearance.
