PRESSURE_VALUE module
The process pressure 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
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, BA114D/06/en/… .
"
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.
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 to the
EMPTY_MODULE module. For a more detailed description, see
