Thermocouple Temperature Measurement System
1. Description
y
Measuring temperature with a thermocouple temperature sensor.
2. Addresses
y
M0: set the number of samples.
y
M1: select the temperature units for the average and present temperatures
y
D20 ~ D23: average Celsius temperature for CH1 ~ CH4
y
D30 ~ D33: average Fahrenheit temperature for CH1 ~ CH4
y
D40 ~ D43: present Celsius temperature for CH1 ~ CH4
y
D50 ~ D53: present Fahrenheit temperature for CH1 ~ CH4
3. Program
Description
y
M0=Off, set the number of samples for the input signals for CH1 to 10, M0=On set
the number of samples for the input signals at CH1 to 1.
y
M1=Off, temperature units = °C; M1=On temperature units = °F.
y
M0=Off, M1=Off, Store the average Celsius temperature for CH1 ~ CH4 into D20 ~
D23.
y
M0=Off, M1=On, Store the average Fahrenheit temperature for CH1 ~ CH4 into D30
~ D33.
y
M0=On, M1=Off, Store the present Celsius temperature for CH1 ~ CH4 into D40 ~
D43.
y
M0=On, M1=On, Store the present Fahrenheit temperature for CH1 ~ CH4 into D50
~ D53.
y
ELCM-TC04ANNN module also stores the average temperature values to special
registers (D9900-D9999). The contents of these special registers can be read with
MOV instructions in the program to obtain the temperature values.
