The text box at the top of the “Message Viewer” screen can be used to send custom messages to the
middleware from the HMI for diagnostic purposes. This can be used to replay a series of actions carried out by
the user. Use the “Send Message” button to send the message to the middleware after entering a valid
message into the text box. The "Export Message History" button will export the last 1000 messages of the
message history as a text file to a USB drive plugged into the HMI computer USB port on the side of the
machine.
