Description
nvoAiValue
SNVT_volt_f
0x000 (0.00 mV) to
0x461C4000 (10V)
The value of the input channel connected to a 0
to 10V 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
NTC20 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.
