HYGRASGARD ® xx - Modbus - T3 | Configuration
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 3 ], enthalpy [kJ ⁄ kg],
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”).
Reading: 13.8
Unit: °C
Index: 1
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.
