RPM to Mach via USB

[Userli]

Hi,

I'm currently building an interface for encoders, calipers and an index sensor to get their signals into Mach via USB CDC.
Whilst the encoder part works quite well now, I'm somehow stuck on getting the index signal into Mach to show the RPMs.
On the interface I can preprocess the index signals up to the real RPM information and would be able to output the data at any stage.
However, I can't figure out, where (meaning into which SDK variable) to feed this in.

Does anybody now?

Cheers, Frank.

Hi Frank,

I've been searching for this a while ago. Didn't find anything, too.

Bye, Steffen

I know it has been a while but vistacnc does make a USB tachometer that works with Mach via a plug in.
