10. Example of Programming
The program stores the temperature data
for 4 channels in the internal output.
Data check
When an error is found, the program turns
M4 on.
The program stores the absolute value of
the temperature difference between the
upper part and the lower part of the liquid
in WR4.
When the temperature difference is
8°C or higher, the program turns R0 on.
When the motor temperature is 100°C or
higher, the program turns R2. on
When the temperature at the upper part of
the liquid is 50°C or higher, the program
turns R3 on. When the temperature at the
lower part of the liquid is 50
the program turns R4 on.
The program stores the difference between the
temperature at the upper part of the liquid and the air
temperature in WR5.
When the air temperature is higher than the
temperature at the upper part of the liquid, the
program turns R5 on. When the temperature difference
is 10°C or lower, the program turns R6 on. When the
temperature difference is 10°C or higher, the program
turns R7 on.
SS0
If R0 or R1 turns on, turn the motor for a
minute.
However, if Y3 turns on, do not turn the
motor.
