READOUT IN THE DISPLAY
By default, the display indicates the following measurements with the corresponding units cyclically and consecutively:
CO
2
content in ppm, air quality (VOC) in %, temperature in °C, relative humidity in % r.H.
The Modbus interface can be used to program an alternative output variable instead of the standard display:
CO
2
content in ppm, air quality (VOC) in %, temperature in °C, relative humidity in % r.H.
In this case, the first line indicates the value and indexwhile the second line indicates the corresponding unit statically .
The index indicates the display type, e.g. dew-point temperature (see the table "Function 06 Write Single Register").
Reading: 27.8
Index: 3
Unit: °C
The Modbus interface allows the display screen to be individually configured, both in the 7 and 14 segment range and in
the dot-matrix range. This means that messages such as those from the PLC can be displayed.
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.
