Rung 1: The get instruction at address 200 multiplies the temperature 100
0
C by
9 and the result, 900 is stored in address 203.
Rung 2: The get instruction at address 203 divides 5 into 900 and stores the
quotient, 180, in address 205.
Rung 3: The get instruction at address 207 adds 32 to the value 180 which is
located at get address 205. The sum of 212 is stored at address 210. Thus
100
0
C = 212
0
F.
Rung 4: If the displayed temperature is less than 180
0
F, the timer initiates
timing for 3 seconds.
Rung 5: If 3 seconds have elapsed, an output at address 01115 will energize a
heating device which will bring the temperature back into the desired range.
