Click PLC HMI Rotary Encoder Dial Input

We will now look at the programming and wiring of a rotary encoder to the Click PLC input. Rotary encoders are modern digital devices that have taken over from the potentiometer in stereos and many other applications. This is because of their fine digital control, and they can fully rotate without end stops. We can connect the rotary encoder to the PLC using just two digital inputs. This human-machine interface (HMI) has the advantage over touch screens and other control methods in the PLC. The operator can control the rate and setpoint with the dial (rotary encoder) without looking at the control. This will allow the operator to concentrate on other tasks.

We will be connecting a rotary encoder with a dial into the Click PLC. The signals being sent from the rotary encoder will be explained. Different methods of programming this input in our PLC will be discussed. Let’s get started.
