Has anyone tried using encoders on normal I/O points on that Plc? The application will run a 360 ppm encoder at 3 rpm. That's 1 pulse per 56ms. The scan time and on-off I/o times are much lower, like 4-8ms. If I am thinking correctly it should be fine, my only worry is if the machine stops right on a pulse edge and it flutters I might get phantom pulses. The reason I am asking is because I would like to use the high speed output for a stepper and I need to read this slow encoder and possibly another higher speed one, and my expansion ports are quickly filling up. (Budget minded too)

counter
Doesn't the 06 allow X0 and X1 to be programmed as high speed counter.

It allows 1 HSIO, it can be either the input or output but not at the same time i believe.

That sounds feasible. I 've never done it with an 06, but have with other PLC's with good results.
