READOUT IN THE DISPLAY
By default, the display indicates the following measured values with the corresponding units cyclically and consecutively:
temperature [°C], relative humidity [% r.H.] (Resolution: 1/10 °C or 1/10 % r.H.)
The Modbus interface can be used to program an alternative output variable instead of the standard display:
dew point [°C], mixture ratio [g ⁄ kg], absolute humidity [g ⁄ m
relative humidity [% r.H.], temperature [°C]
In this case, the first line indicates the value while the second line indicates the corresponding unit statically.
The index in the third line indicates the display type,
e.g. dew point temperature (see the table "Function 06 Write Single Register").
The Modbus interface allows the display screen to be individually configured, both in the 7 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 display value) must contain the value 10.
The registers 4x0002 to 4x0022 contain information about the characters and segments to be displayed.
The two left-aligned positions are represented by the register 4x0003 (range -9...99). The value 0 switches
off the display of both positions. The display is only active if the register 4x0002 has positive values.
In the default setting (register 4x0001 contains the value 0 for the standard display),
even the characters I-Q (registers 4x0014 to 4x0022) are freely programmable in the dot-matrix range.
In this case, the current measured value is automatically displayed in the 7-segment area.
