scaling

[cool]

Hi all,

I have limmited programing ability and need help to setup a counter with scaling.
for example each input from X 1 needs to be multiplied by 2.55 and then placed into D 1.
I use mitsubishi FX PLC's

I don't know mitsubishi at all, but i would just let the counter count, and multiply its accumulator value by 2.55, depositing the result in D1

Count=0 D1=0
Count=1 D1=2.55
Count=2 D1=5.1

etc.

D1 would need to be a floating point register, or you will get

Count=0 D1=0
Count=1 D1=3
Count=2 D1=5
Count=3 D1=8
Count=4 D1=10
