5 Display and function buttons
The device and process parameters can be viewed and edited (if available) on the display using
the function buttons. For device parameters, see section 6 “System menu”.
To view or edit the process parameters, display forms have to be programmed with different dis-
play elements. Jump conditions have to be created to let an operator to switch between the display
forms using the function buttons. Jump condition can be a button event of a variable event. For
further details about display elements and jump conditions use Help in akYtec ALP.
