READOUT IN THE DISPLAY
A static display of dew point (in °C), mixture ratio (in g ⁄ kg), absolute humidity (in g ⁄ m
relative humidity (in %) and temperature (in °C) can be preset via MODBUS.
In the first line of the display the measured value and in the second line the corresponding unit is displayed.
The index indicates the display type, e.g. dew-point temperature (see the table "Function 06 Write Single Register").
The Modbus interface allows the display to be individually configured in the 7-segment area and in the dot-matrix area.
For the individual display, the register 4x0001 (physical value displayed) must contain the value 10.
The registers 4x0002 to 4x0012 contain information about the characters and segments to be displayed.
The dot-matrix area is also programmable in the default setting (register 4x0001 contains the value 0).
In this case, the current measured value is automatically displayed in the 7-segment area
