Object NVs for the XFL521B
The value of the input channel connected to a
0...10 V signal after it has been filtered. Voltage
is transmitted in mV. When configured for a
temperature sensor, the channel transmits the
measured resistance.
The value of the input connected to either an
NTC20k or PT1000 sensor with a resolution of
0.1 °C. If the sensor channel is configured as a
voltage input, the temperature value is invalid
(0x7FFF).
Specifies the type of sensor for a particular input
channel.
Specifies the difference in the raw value
measured by the A/D converter is required
before the value of the sensor is transmitted.
Specifies a resistance value to add to the
resistance measured for a temperature sensor.
