3. Instruction Set

3-459

Program Example 3:

1. Assume the source value S

, D100 = F500, max. source value D0 = F3000, min. source value

D2 = F200, max. destination value D4 = F500, and min. destination value D6 = F30. When X0

= ON, M1162 is set up to adopt floating point operation. DSCLP instruction executes and the

result of proportional calculation will be stored in D10.

2. Equation: D10 = [(F500 – F200) × (F500 – F30)] ÷ (F3000 – F200) + F30 = F80.35. Round off

the result into an integer, D10 = F80.

Points to note:

1. Range of S

for 16-bit instruction: max. source value ≥ S

≥ min. source value; -32,768 ~

32,767. If the value exceeds the bounds, the bound value will be used for calculation.

2. Range of integer S

for 32-bit instruction: max. source value ≥ S

≥ min. source value;

-2,147,483,648 ~ 2,147,483,647. If the value exceeds the bounds, the bound value will be

used for calculation.

3. Range of floating point S

for 32-bit instruction: max. source value ≥ S

≥ min. source value;

adopting the range of 32-bit floating point. If the value exceeds the bounds, the bound value

will be used for calculation.

4. When adopting the slope equation, please note that the Max. source value must be larger than

the min. source value. However the max. destination value does not need to be larger than the

min. destination value.
