In the basic module you can use (I3, I4, I5, I6) as high speed input. The normal input is max. 4Hz. The high speed input is max. 5kHz. Please make sure to avoid exceed this limit of 5kHz. Besides of it, you can use the program normally. Hope it helps.
	Rgds, Padre Pio Automation

I'm thinking more about how the programming would look in LOGO! and whether it can be done or if a larger PLC is needed for this. I've tried using a counter to count pulses and would like to be able to compare them with a fixed RPM, also with plus or minus 5%, but that's where it goes wrong for me.

All other funktion block relates on the LOGO! cycle time. This also cannot be simulated. You have to test it at a real LOGO! Hope this helps
