Log on/log off (PIN)
All device parameters are assigned to one of four user levels. You do not need to log on for
the lowest user level. But write access to parameters always requires the corresponding
authorization for security reasons:
Protected parameters are identified by the symbol . If you want to edit a protected parameter
or start a wizard, you are prompted in a window to enter a PIN of the currently required user
level. The PIN consists of four numbers each of which is represented by a * during input.
The currently selected user level remains set until you log off or select a higher user level. As
long as you are logged on, the device is locked for other write accesses, for example,
SIMATIC PDM via Ethernet.
When you log off (2 x <MEAS>), you can either accept the changes or discard all of them.

Views structure the access to the functions of the device or its components. Only the operator
control options corresponding to the configuration of your device are output on the display.
Logbook
The device has a logbook for logging abnormal events, for example, error messages that
require acknowledgment. Module-specific messages are always stored permanently on the
module itself. With the LUI, the device provides a uniform user interface that logically combines
all the individual logbooks. When a module is replaced, these logbook entries disappear from
the logbook of the device.
The logbook or logbooks are structured as a circular buffer. When the buffer is full, the oldest
entries are overwritten by new ones. This means the logbook entries are displayed in
chronological order. By setting filter functions you can limit the display range to meet your
requirements.
