Wiring Stack Light to Click PLC

Stack lights are usually modular stackable components that provide a visually illuminated and audible indication for machines, systems, and processes. They are usually located on top of equipment to provide this notification to personnel in the area.

Stack lights are also known as signal tower lights, indicator lights, warning lights, industrial signal lights, tower lights, and light towers.
We will be connecting a Patlite NPS-402-RYGB Super Slim stack light to our Click PLC.

These stack lights come in preassembled units in the most popular combinations of colours with ABS resin main bodies that offer superior impact and heat resistance; double-insulated construction enhances durability and safety. Interchangeable light modules require no rewiring. Let’s get started. Continue 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!

Click PLC Update Firmware

Firmware is usually PLC operating system code that is written into a read only memory. The BIOS (Basic Input Output System) of a PC (personal computer) is a good example of firmware. It provides the low level interface between the hardware and software. The Click PLC firmware comes with the programming software.

We will be updating our firmware of our Click PLC from 2.10 to 2.30. Let’s get started! Keep on Reading!

The 7 Essential Parts of a PLC System

When I was in school PLC’s were just in their infancy. We were taught that the PLC consisted of the central processing unit (CPU), analog and digital inputs and outputs. Everything was programmed with dedicated handheld devices and/or software devices on specialized hardware. We now have modern PLC systems that are capable of so much more. Let’s look at how we can now break up these modern PLC system into the seven essential components.

CPU
Inputs and Outputs (I/O)
Analog I/O
Specialty I/O
Programming Tools
HMI
Networking Continue Reading…

Click PLC Compare and Math Instructions

Compare and math instructions in the Click PLC will allow you to do a number of things. We will use the compare instructions to turn on bits which will indicate production shifts. Using the math instruction we will convert the number of units made to a weight.  Keep on Reading!

Click PLC Installing the Software

Previously we discussed the Click PLC System Hardware – Video. Today we will be installing the free software required to program the PLC. This includes the actual program and communication drivers.  Keep on Reading!

Click PLC System Hardware

Many people ask me what I do when looking at a new PLC model or system. My approach is very straight forward and we will view this in action with this Click PLC series. This series will go from examining the hardware to programming and communicating to the PLC in several ways. If you have questions along the way, please let me know. Keep on Reading!
