Many of these objects can be set up to manipulate tag values using expressions, and show
the expression result rather than the original tag value. For information about expressions,
see Chapter 23.
You can also attach visibility animation to these graphic objects, to show or hide the
objects based on changes in tag or expression values. For information about visibility
animation, see page 22-9.
For information about creating graphic objects, see Chapter 20. For information about
setting up graphic objects, see Chapter 21 or Help.
Show the date and time
To show the current date and time, create a time and date display. This object uses the
operating system’s date and time, in the format of the application’s current language, and
therefore does not require tags or expressions.
View alarms and messages
The operator can view alarms and other messages at run time using these graphic objects
and graphic displays:
The default alarm and information displays open automatically when the assigned tags
match messages’ trigger values. The default diagnostics display opens automatically
when system activity occurs. If desired, you can set up your own graphic displays to open
automatically, instead of the default displays. You can also set up any of the displays to
open when an operator presses a Goto display button or selects a display in the display list
selector.
