Can you please share your experience using the 1756-HSC? We are having difficulty to filter the noise from the input signals.

 

I have had very good results using a 24vdc incremental encoders on both channels simultaneously. The only issues I had were that to set preset values in the counters (on first scan) you need to verify that the card is communicating with the processor and then message the preset values to the card. Other than that initial issue all seems well.
