To obtain the value in
S
2
, users have to use the slope equation below,
round the result to the nearest integer, and get a 16-bit integer. To obtain
the value in
S
3
, the users have to use the offset equation below, round
the result to the nearest integer, and get a 16-bit integer.
Slope
equation:
S

are 500, 168, and -4 respectively.
When X0.0 is ON, the instruction SCAL is executed, and a scale is
stored in D0.
Equation:
D0=(500×168)÷1000+(-4)=80
