At run time the graphic display containing the information message display object opens when the Value connection at the data source changes from zero to any non-zero value. If the value matches a message’s trigger value, the corresponding message is shown. If the non-zero value does not match any configured trigger value, question marks are displayed. The display opens on top of the current display.
If the Value connection value changes to 0, the display closes.
Tip: |
Use the Information Setup editor to specify the graphic display to use for information messages, specify the file containing the messages to display, and assign the Value connection. |
The application creates a default graphic display called [INFORMATION] that contains an information message display object and these buttons:
If you modify the default display or create your own graphic display containing an information message display, the display might contain different buttons.
When the operator presses the Acknowledge button, the Ack connection 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. Assign the Ack connection and specify a hold time in the Information Setup editor.
Tip: |
To close the display when the operator acknowledges the message, configure the data source to set the Value connection to 0 when the Ack connection is set to 1. |
