Description of MODULE PRESSURE XD
The TxPDO Derived Value (equivalent to the data point 0x60n0) provides the volume flow determined from the differential pressure.
The configuration object Volume Flow Display ( 0x80n0 ) sets the display behaviour of the bar graph and LCD. In this case, the value
range of the bar graph can be defined using the start point Bar Graph Minimum Value and the end point Bar Graph Maximum Value,
and its colour (standard white) edited. Refer to the bar graph module for the colours Level OK, Level WARN and Level ERR. If it is not
available, green, yellow and red are used as specified colours. A system-specific display text (7 characters) for the lower line can also
be specified.
In the Volume Flow Configuration ( 0x80n1 ) object, the K-value and the calculation formula for calculating the volume flow
from the differential pressure are defined.
The Volume Flow Description ( 0x90n0 ) object contains the module description in text form, the Volume Flow Unit ( 0x90n1 )
object displays the measurand unit.
