AERASGARD ® RFTM - LQ - PS - CO2 - Modbus | Configuration
READOUT IN THE DISPLAY
By default, the display indicates the following measurements with the corresponding units cyclically and consecutively:
CO2 content in ppm, air quality (VOC) in %, temperature in °C, relative humidity in % r.H., particulate matter (PM) in µg/m
The Modbus interface can be used to program an alternative output variable instead of the standard display:
CO2 content in ppm, air quality (VOC) in %, temperature in °C, relative humidity in % r.H., particulate matter (PM) in µg/m
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. particulate matter (see the table "Function 06 Write Single Register").
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.
