A rotary encoder (RT) is a device ... the rotary encoder has 2 coding pins that are either HIGH (1) or LOW (0). If you treat the pins as binary, you can read ... of 01, the next reading can either be ...

It is based on some assembler code I wrote for a PIC years ago, and relies on polling the current state of the two input pins from a rotary encoder, and comparing these two binary bits with their ...

Rotary and linear optical encoders are common in position and motion sensing. ... For each encoder position, there is a different binary output -- shaft position is absolutely determined.

Encoder output data is sent to the controller via parallel binary, analog voltage or current, Profinet, Ethernet Powerlink, EtherNet/IP, Modbus, DeviceNet, Profibus, CANopen, or other networks.
