    Hello, I have a question?
    I want to know if I can connect an absolute encoder to a PLC BRX
    and how to do it

    Yes. Depending on the encoder type you might use discrete inputs. The inputs need to be in sequence preferably starting with the first input. Then use the Gray code instruction to decode the inputs into a value. See help topic DMD0024

        Also keep in mind you don't have to use all the bits from the encoder if you don't need them all. It just depends on your resolution and how many I/O you have available.

          the encoder that you use is not of a high resolution 250 PPV and has an 8-bit output
