Use the information acknowledge button
When the operator presses the information acknowledge button, if the Ack connection is
assigned, the connection value is set to 1 at the data source. The value is held as long as
the operator presses the button, or for the acknowledge hold time, whichever is longer.
Then the connection is reset to 0.
Create your own information message display
You can create your own graphic display for showing information messages, containing

If you create your own graphic display, use an On Top display and select the Cannot Be

For more information about the information message display graphic object, see

information message display. For information about setting up a Goto display button and
specifying the display to open, see Help.
Close the display
The information message display closes when the Value connection’s value changes to 0.
To automatically close the display when the operator acknowledges a message, set up the
data source to set the Value connection to 0 when the Ack connection is set to 1.
