Operation messages options
If you have selected this variable via the check box, the fault message is sent to a connected printer.
Each message can have a Priority allocated. Priority levels range from 0 to 15, where 15 stands for highest, 0 for lowest priority. If several messages are in a queue, their priority determines the order in which they will be displayed.
A number can be allocated to every message for easier identification. This message number is issued together with the message. If you design a project in several languages, you can use the message number for exact identification of a message regardless of its language.
