Write a LD program to control the temperature of the fluid in a
process tank close to 400°C. Assume that the heater contactor is
connected to PLC 5 output 0:001/01, a temperature low switch set at
395°C is connected to input 1:000/00 and temperature high switch
set at 405°C is connected to input 1:000/01. The temperature low
switch is closes if the fluid temperature is below 395°C and opens
at a temperature of 395°C or higher. The temperature high switch is
closes if the fluid temperature is below 405°C and opens at 405°C
or higher temperatures.
