Configuration
READOUT IN THE DISPLAY
By default, the following measurement
is displayed
statically
with the corresponding unit in the first line of the display:
Temperatur
in °C (the resolution is 1/10 °C)
Sensor breakage and sensor short circuit are detected and reported as an
error
, which is indicated on devices equipped with
a display. The error status can also be retrieved by means of a bus query
Sensor breakage
Error message:
Err1
Readout in the display:
999.9 °C
Sensor short circuit
Error message:
Err2
Readout in the display:
– 99.9 °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.
