Operation
6.1 Local User Interface (LUI)
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:

Service
Protected parameters are identified by the symbol
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.
Logbook
The device has a logbook for logging extraordinary device-specific and module-specific
events, for example, error messages that require acknowledgment. Module-specific
messages are transferred to the replacement device in case the module is replaced.
The logbook is 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.
