MyPro display.
Various symbols are displayed depending on
the instrument settings.
4.5 Locking concept
Access to instrument operation and write pro-
tection for field operation can be disabled via
the keypad or the communication interface.
The keypad has priority over the interface, i.e.
an instrument which has been locked in the
field cannot be unlocked via the communica-
tion interface.
Note:
•
The previous locking status is
retained after a power failure or
reset.
•
The factory setting (status at time
of delivery) is ‘unlocked’.
Unlocking / locking via interface and field operation (operating level 2):
See chapters 4.7 and 5.
