Adsolute Encoder to Unistream

[Jose Gilberto]

I need to connect a Rotary Encoder Absolute (Omron E6CP-AG5C-C) to the UniStream I plan to use high speed module, who has experience with this application

[Joe Tauser]

That encoder has 8 data lines - you use digital input (not a high speed) module with npn inputs and decode the Gray code it outputs in your logic.

Unitronics does not have a built-in Gray Code decoder function that I'm aware of.  Here's link on how convert 4 bit Gray Code to binary-

You can extrapolate this to handle 8 bits, and then use the Bits to Num function to turn that into a value.

What is your application that you need an absolute encoder?
