Program Example 2:
1. Assume source value S
1
= 500, max. source value D0 = 3000, min. source value D1 = 200,
max. destination value D2 = 30, and min. destination value D3 = 500. When X0 = ON, SCLP
instruction executes and the result of proportional calculation will be stored in D10.
Equation: D10 = [(500 – 200) × (30 – 500)] ÷(3000 – 200) + 500 = 449.64. Rounding off the result
into an integer, D10 = 450.
