Click PLC HMI Rotary Encoder Dial 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 into the PLC using just two digital inputs. This human machine interface (HMI) has the advantage over touch screens and other methods of control into the PLC. The operator can control the rate and set point with the dial (rotary encoder) without looking at the control. This will allow the operator to concentration on other tasks.

We will be connecting a rotary encoder with 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. Keep on Reading!

Trumeter ADM100 Series Graphical Panel Meter

The Trumeter ADM100 Series Graphical Panel Meters provide the visual representation of an analog meter and the accuracy of a digital meter all in one unit.
These meters feature a programmable bar graph and alarms to immediately alert operators when a parameter is out of range. In addition, a four-character messaging area displays custom messages, alarms and annunciators.

Every meter is configurable to measure voltage, current or frequency. The M100-Lx model is for use with a low voltage power supply, and the ADM100-Hx is for use with mains power. Both models offer two LCD options – positive LCD for bright conditions or negative LCD for dark environments.
We will be looking at unboxing the unit, powering it up, installing the software and setting and communication to the Trumeter AMD100 Series Graphical Panel Meter. Let’s get started. Continue Reading!
