The arrows beside the connection names indicate the direction data flows between the tag
or expression and the object:
 A right arrow indicates that data flows from the object to the tag or expression only. In
other words, the object can write to the tag or expression.
 A left arrow indicates that data flows from the tag or expression to the object only. In
other words, the object can read from the tag or expression.
 A double arrow indicates that data flows in both directions. In other words, the object
can write to, or read from, the tag or expression.
Adding tooltips to graphic objects
To provide information about a graphic object to an operator, add a tooltip to the object.
By default, an object has no tooltip. If you add a tooltip, it shows at run time, when the
operator positions the pointer over the object for a few seconds.
The Connections tab is blank, if multiple objects are selected. You can only assign a tag or
expression to one object at a time.
Type a tag name or
expression in this column.
The arrows show the
direction in which data
flows between the
object and the tag or
expression.
This box describes the
selected connection,
and the type of data it
uses.
