Hi...
I want to measure machine position using 2000 PPR inc encoder that connect to 1769-HSC module.
How to configure the 1769-HSC to read the machine position?
Thank you for help...

what processor are you using?

We used 1769_L35E processor.

First you should configure your 1769-HSC by add it to your projet. You can use up to 4 encoder on this card (depend of configuration). You can select a multiplier, for example with your 2000 PPR encoder X4 mean 8000 pulse per revoltion (card use rising and falling edge to do this). When your done, you'll get access to tag in your controller tag. HSC:0.currentcount is the high speed counter value, you can read it in your program.

For more detail I suggest you some reading (about 170 page on 1769-HSC) at rockwell web site:
