6.7 Locking the Programming of the Sensor 

(man. 6.3.12)

The function parameters of each measuring point are protected by the locking
mode up to an adjustable locking level. Before any programming is performed
the locking mode must be correspondingly lowered. If a dot is indicated
following the locking mode on the display then a modification is not possible.

If programmed, the element flags and the multiplexer settings are indicated on
the display next to the locking mode (see manual 6.10.2/3).
Keyboard locking and a locking code can be used to protect against
unauthorised modification (see 5.4) during a measurement and to protect the
programming and the process control.
