If COUNTS is selected as pressure unit, the switchover pressure can be calculated
by means of the following formula (PV is the abbreviation of Process Value):
PV
mbar
= 10 (6 × COUNTS / 4000) - 42.5
The following settings can be made with the five possible switch positions.

This parameter represents the setting of the calibration switch "CAL ADJ", which is
used for adjusting the sensitivity of the gauge (
→ [4], [6]).
The value output corresponds to the marking on the switch.
The following parameters (ID 204 … ID 209) present copies of elements
of the Exception Detail Alarm (ID 27) or the Exception Detail Warning
(ID 28). These parameters are made available in order to allow masters
that do not support the Profibus DPV1 to access the elements of the
Exception Detail Alarm and Warning via the parameter channel. Since
the parameter channel has a limited actual data length (4 bytes), the
attributes ID 27 and ID 28 cannot be read via the parameter channel.
This parameter corresponds to the Common Exception Detail Alarm of the
Exception Detail Alarm (ID 27).
This parameter corresponds to the Device Exception Detail Alarm of the Exception
Detail Alarm (ID 27).
This parameter corresponds to the Manufacturer Exception Detail Alarm of the
Exception Detail Alarm (ID 27).
This parameter corresponds to the Common Exception Detail Warning of the
Exception Detail Warning (ID 28).
This parameter corresponds to the Device Exception Detail Warning of the
Exception Detail Warning (ID 28).
This parameter corresponds to the Manufacturer Exception Detail Warning of the
Exception Detail Warning (ID 28).
