10.3.5.3 Addressing a temperature sensor
To address a temperature sensor, use the following structure:
DEV:<UID>:TEMP
where <UID> is a unique identifier that is allocated to each board, based on its SPI location.
The configuration settings for a temperature sensor are DEV:<UID>:TEMP followed by:
COMMAND OPTIONS Read/Write DESCRIPTION
MAN HVER R
Reads the hardware version of the daughter
card
MAN FVER R
Reads the firmware version of the daughter
card
MAN SERL R Reads the serial number of the daughter card
NICK R/W Sets the name of the device
STAT R
Reads the alarm flags for the device (Hex
Format)
TYPE DUM:PTC:NTC:TCE:DDE R/W Sets the sensor type
EXCT TYPE UNIP:BIP:SOFT R/W Sets the excitation type
EXCT MAG 0 - 1000 R/W Sets the excitation magnitude
CAL OFFS 0 - 1000 R/W Sets the offset of the calibration curve
CAL SCAL 0 - 1000 R/W Sets the scale of the calibration curve
CAL FILE R/W
Sets the calibration file to use to calculate the
temperature
CAL INT NONE:LIN:SPL:LAGR R/W
Sets the interpolation method for the
calibration file. SPL and LAGR options not yet
implemented.
CAL HOTL 0 - 2000 R/W
Set the maximum value for temperature
setpoint (hot limit)
CAL COLDL 0 - 1000 R/W
Set the minimum value for temperature
setpoint (cold limit)
CAL CAL R/W
Calibrates the hardware. Reads the time of
the last calibration (seconds since 1970-01-01
00:00:00 UTC)
RSMP R/W Signal filter buffer length (number of samples)
The signals for a temperature sensor are DEV:<UID>:TEMP followed by:
COMMAND Read/Write DESCRIPTION
SIG VOLT R Sensor voltage
SIG CURR R Sensor current
SIG TEMP R Measured temperature
SIG RTMP R Raw temperature
SIG POWR R Sensor power dissipation
SIG RES R Measured resistance (PTC/NTC)
