Temperature PWM and PID Control related commands
The 12V/1A PWM output may be used for dew-heaters and in conjunction with one or more tem-
perature sensors, for the precise PID temperature control of instruments.
3.6.1
TEMPX
Temperature of sensor nb. X.
GET TEMP0
Get the current temperature from the temperatur sensor plugged into the stepper motor unit (float).
If no sensor is attached (or the sensor is defective), this will read ”-128.0”.
$BS GET TEMP0\
r
\n
Example answer:
$BS STATUS TEMP0:17.01\
r
\n
GET TEMP1
Get the current temperature from the sensor plugged into the controller board (float). If no sensor is
attached (or the sensor is defective), this will read -128.0 .
$BS GET TEMP1\
r
\n
Example answer:
$BS STATUS TEMP1:22.56\
r
\n
3.6.2
TEMPX OFS
TEMP0 OFS and TEMP1 OFS hold a constant offset for the measured temperatures TEMP0 and
TEMP1. May be used for precise temperature calibration.
GET TEMP0 OFS
Get the temperature offset for temperatur sensor plugged into the stepper motor unit (float, DEFAULT
= 0.0).
$BS GET TEMP0_OFS\
r
\n
Example answer:
$BS STATUS TEMP0_OFS:0.00\
r
\n
SET TEMP0 OFS
Set a constant temperature offset for temperatur sensor plugged into the stepper motor unit (float,
decimal point MUST be given!).
$BS SET TEMP0_OFS:-0.43\
r
\n
Example answer:
$BS OK\
r
\n
GET TEMP1 OFS
Get the temperature offset for sensor TEMP1 (float, DEFAULT = 0.0).
$BS GET TEMP1_OFS\
r
\n
Example answer:
$BS STATUS TEMP1_OFS:1.12\
r
\n
