rpm counter

[TozoM8]

I have a drum that I have to display the RPM. It has 8 magnets and a Hall sensor. I can convert the 8 signal to 1 rpm with linearization, but how do I display it as rpm instead of just an increasing number until I reset it? Any help would be greatly appreciated.

Thanks!

Hi,

   

                 Use High speed inputs. Detailed example is given in Visilogic(if vision series PLC.) as well as U90 ladder(if M90 series PLC).

in U90 ladder. goto: help-> Sample U90 projects-> Motion Control folder-> motor speed.U90.

In visilogic. help-> Examples-> Version 900-> Project Examples-> HSC_HSO folder-> V570_Frequency-precise meter.vlp
