Explanation:
1. The input value in S
output value in S , and the comparison result is stored in D.
2
If the minimum output value in S
D is equal to the minimum output value in S
If the maximum output value in S
D is equal to the maximum output value in S
If the input value in S
maximum output value in S
If the minimum output value in S
is not executed.
2. Only the 32-bit instructions can use the 32-bit counter.
Example:

When X0.0 is ON, the state of X1 is converted into the binary value, and the conversion result
is stored in D0. Besides, the value stored in D0 is compared with 500 and 5000, and the
comparison result is stored in D1.
