Table 5. LONMARK Object NVs for the XFL521B
NV Name Type Range Description
nvoAiValue SNVT_volt_f
0x000 (0.00 mV) to
0x461C4000 (10 V)
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.
nvoAiTemp SNVT_temp_p
0xEC78 (-50 °C) to
0x3A98 (150 °C)
Invalid = 0x7FFF
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).
UCPTSensorConfig
0 = not used,
9 = 0 to 10V with pull-up resistor
4 = NTC20
5 = PT1000
10 = 0 to 10V without pull-up
resistor (default = 8)
Specifies the type of sensor for a particular
input channel.
UPCTSendOnDelta SNVT_count 0 to 4095 (default = 2)
Specifies the difference in the raw value
measured by the A/D converter is required
before the value of the sensor is transmitted.
UCPTWireOffset SNVT_res 0 to 6553.5 ohm (default = 0)
Specifies a resistance value to add to the
resistance measured for a temperature sensor.
