PRESSURE_VALUE module
The process pressure value (IEEE 754 floating point number), including status, can be cycli-
cally transmitted via the PROFIBUS Master (class 1) directly to the measuring device using
the PRESSURE_VALUE module (slot 8).
The process pressure value is used to compensate for large variations in process pressure,
e.g. Ammonid gas applications. The unit pressure selected in the measuring device is used.
More details to the PROCESS PRESSURE function are contained in the "Description of Device
Functions" manual, BA00114D/06/… .
"
Caution!
The process pressure is a non-volatile device parameter. A constant overwriting of this non-
volatile device parameter via the PROFIBUS is to be avoided

!
Note!
The status is not evaluated by the device.
FRACTION_INPUT module
The analyzer input value (IEEE 754 floating point number), including status, can be cyclically
transmitted via the PROFIBUS Master (class 1) directly to the measuring device using the
FRACTION_INPUT module (slot 9).
Gas mixtures are read in from a gas analyzer using the analyzer input value.
More details on the ANALYZER INPUT function are contained in the "Description of Device
Functions" manual, BA00114D/06/…

EMPTY_MODULE module
The measuring device is a so-called modular PROFIBUS slave. In contrast to a compact slave,
the structure of a modular slave is variable - it consists of several individual modules. In the
GSD file, the individual modules are described with their individual properties. The modules
are permanently assigned to the slots, i.e. the sequence or arrangement of the modules must
be observed when configuring the modules. Gaps between configured modules have to be
assigned the EMPTY_MODULE module. A more detailed description is provided on
66.
