Use information messages to give the operator messages about the process, prompts or instructions, and information about the current states.
When you create a project, the application creates a default graphic display called [INFORMATION] that contains an information message display object. The graphic display also contains buttons for acknowledging messages and closing the display. You can use the default display, or create your own display for displaying information messages at run time.
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 value does not match any configured trigger value, question marks are shown.

Configure the Value connection at the data source to change to the trigger value that suits the particular message. For example, suppose your plant uses a bag-filling machine that requires the operator to remove the full bag and set up an empty bag between each fill. You might configure the data source to monitor the bag-filling machine, and when the bag is full, set the Value connection to the trigger value. This would trigger a message like this: "Bag filling is complete. Transfer full bag to conveyor and hook new bag in place."
