Example
Thermocouple Temperature Measurement System
1. Description
•
Measuring temperature with thermocouple temperature sensor.
2. Addresses
•
D20 ~ D23: average Celsius temperature at CH1 ~ CH4
•
D30 ~ D33: average Fahrenheit temperature at CH1 ~ CH4
•
D40 ~ D43: present Celsius temperature at CH1 ~ CH4
•
D50 ~ D53: present Fahrenheit temperature at CH1 ~ CH4
3. Program
description
•
When the ELC goes from STOP to RUN, set the number of samples for the average
temperatures for CH1 ~ CH4 to 10.
•
Store the average Celsius temperature at CH1 ~ CH4 into D20 ~ D23.
•
Store the average Fahrenheit temperature at CH1 ~ CH4 into D30 ~ D33.
•
Store the present Celsius temperature at CH1 ~ CH4 into D40 ~ D43.
•
Store the present Fahrenheit temperature at CH1 ~ CH4 into D50 ~ D53.
