The Operation Panel is displayed after the set return time has elapsed, provided that at least one measured value has been configured.

The user can select which of the measured operating values will be displayed on the Operation Panel by means of an “m out of n” parameter. When more measured operating values are selected for display than the LC display can accommodate, then the display will either switch to the next set of measured operating values at intervals defined by the setting for LOC: Hold-time for Panels or when the appropriate key on the local control panel is pressed.
