Click PLC High Speed Counting – Part 2

The Ethernet Click PLC high speed counter has seven different modes of operation. In Part 1 we discussed the High Speed Count Mode, Interval Measurement Mode,
Duration Measurement Mode and Frequency Measurement Mode.

This 100 KHz counter can accept Up, Down, Up/Down, Pulse/Direction or Quadrature (with Z) inputs.
We will be looking at the last three different high speed counter modes available in the click. (External Interrupt, Pulse Catch, Filter) This is all setup through a user friendly graphical user interface. We will also combine the Frequency Measurement and the High Speed Count in one application. Let’s get started! Keep on Reading!

Click PLC High Speed Counting – Part 1

The Click PLC family has been updated, and now has the ability to use high speed counting. This is available on all of the Ethernet units that have DC inputs. The faster processor on the Ethernet unit (3 to 10 times faster than the basic unit) allows this capability. There are seven (7) different modes of operation for the high speed counter available so adaption to your automation solution is easy. The input can count Up, Down, Up/Down, Pulse/Direction or Quadrature (with Z). Maximum speed on the high speed counter inputs are 100 kHz. That is 100,000 pulses per second.

We will be looking at the different high speed counter modes available in the click. This is all setup through a user friendly graphical user interface. Let’s get started! Keep on Reading!

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!
