2.6 Securing the values (access rights)
Within the DL210 a setting can be made for each existing value of whether it can be read
and/or written by the appropriate access parties. This enables the DL210 to be used in a
very flexible manner. In the field subject to calibration regulations, the rights are
appropriately preset.
The following "access parties" are defined in the DL210:
Ø
Calibration official "P"
Access via calibration button located in the DL210.
Ø
PTB logbook:
"PL"
Access via supplier's combination when the
PTB logbook is not full.
Ø
Supplier
"S"
Access via supplier's combination
Ø
Customer
"C"
Access via customer's combination
For each value it can be defined whether the above-mentioned access party may read the
value or write to it. Under which lock the desired value (for the factory setting) is located is
described in the following chapters (refer to Chap. 3 and following pages).
These are to be followed, because WinPADS can be installed as a testing station,
supplier's or customer's version and access to the device occurs accordingly.
F
If, for example, the supplier's lock is open (factory setting), the customer can
also change the supplier's values!
Depending on the application, an input which is not to be used as an input subject to
calibration regulations can also be placed under the supplier or customer lock to be able to
use it, for example, as a signalling input. A change is however only possible with the
calibration lock open.
2.6.1 Calibration lock and calibration switch
The highest ranking lock for securing the calibration parameters is the calibration lock. All
values, for example which are used for the processing and storage of volume counters,
are subject to this lock. The calibration lock applies both to entries via the keypad as well
as for access via the optical or internal modem interface. If the lock is locked, all attempts
to set values are acknowledged with an appropriate error message (see Chap. 2.5.3).
The calibration switch is realised as a pushbutton and is located inside the DL210 next to
the battery and is sealed with a sealing label.
The calibration lock is opened by actuating the button once (a flashing "P" appears in the
display under the membrane label "Status") and also closed again (flashing "P" goes out).
The parameters protected under calibration regulations are each identified with "C" in the
lists in the functional description.
2.6.2 Access lock "PTB logbook"
The DL210 has a calibration logbook in which changes of parameters subject to the
calibration lock are saved. Parameters which are written into the logbook during a change
are identified in the menu list of the function description (Chapter 3) with the access right
"PL". When the PTB logbook is not full, these parameters can only be changed with the
