Click to Click PLC Communication – Remote IO

We will connect two Click PLUS PLCs and communicate in three different ways. Using the send and receive commands, we will set up one PLC to be the master (client) and communicate with the slave (server). WiFi, Ethernet, and Serial communication will share common memory areas between the Click PLCs.
Click to Click PLC CommunicationThe send and receive commands have been covered before in our Click PLC Series, but we will look further at the timing of the communication. Detecting and correcting communication errors will be discussed and implemented. We will also create a heartbeat for the remote Click slave (server) PLC. This will allow the remote controller to determine if communications have stopped with the Click master (client). Wiring a pushbutton and some ladder logic code will allow us to time the throughput of each of the communication methods. Let’s get started.

How to Connect Pushbutton Switch to PLC

We will connect a lighted pushbutton switch to a programmable logic controller (PLC). Using our Click PLUS PLC, we will be assembling, wiring, programming, and testing our pushbutton switch system. The Fuji Electric pushbutton, normally open (NC) contact, will be wired to the first PLC (X1) input. The LED light will connect to the Click PLC (Y1) first output.
How to Connect Pushbutton Switch to Programmable ControllerFerrules will be discussed and demonstrated as a method of wiring any stranded wire. The use of ferrules applies to any automation devices with screw terminals. A ladder logic program will be developed to start and stop this lighted pushbutton light using just a single input. The output LED will turn on if the button is pressed for three seconds. Pressing the button again will turn the light off. This is the safest way of using one input to start and stop output. Let’s get started.

EasyPLC Solder Robot PLC Programming

The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that are used to show different programming techniques. The solder robot example is one of these machines. This will demonstrate a sequencer robot example. In this case, four rivets are welded using a robot. The logic will step through various steps to perform the task.
EasyPLC Solder Robot PLC ProgrammingWe will use a Click PLUS PLC and the Click programming software to program this EasyPLC simulator solder robot. This will be done using Modbus TCP (Ethernet) for communications. The program will control the stopping and welding of the boxes. Using the five steps for program development, we will show how this sequencer is programmed. Let’s get started.

Learn PLC Programming Free Now – Video

We can learn plc free by using the Do-More Designer simulator. This is free, fully functional programming and simulator software. The PLC simulator also allows communication through the Ethernet and Serial ports of the computer to help you learn about HMI and communication. This video series will take you through the simulator’s basics of installing, programming, and testing your ladder logic programs.
Learn PLC Programming Free NowNo physical hardware is required to learn how to program programmable logic controllers (PLC). This series was initially released six years ago but is still relevant today and is part of our PLC beginner’s guide.
We will briefly discuss each of the videos in this series and provide the URL links. Let’s get started.

Building a PLC Program that you can be Proud of

Building a PLC program series will take you through developing and programming PLC logic. This six-part series was released almost seven years ago but is still relevant today. Each part will add and build upon the previous step. This series will look at different ways to solve the same machine logic.
Using discrete inputs and outputs to control traffic lights and cylinders, we progress we introduce additional methods to solve logic. We look at sequencers in a new way and learn how to write programs to allow users to teach the new sequence. This will develop your PLC programming skills. The Do-More Designer programming and AdvancedHMI (VB.Net) software are utilized without purchasing physical hardware. Let’s get started.

PLC Programming Mixing Tank – EasyPLC / Do-More

Previously we looked at the easy PLC machine editor design simulation. We created a mixing tank simulation using the EasyPLC machine editor. The tank included a control panel and operation indication.EasyPLC Machine Editor - Design a Simulation We will now use the Do-More designer programming software to program the ladder logic for this EasyPLC mixing tank application. The built-in simulator of the Do-More Designer programming software will be used to actually run the program and control our EasyPLC mixing tank machine. Development of this program will be done using the five steps for PLC programming. Let’s get started!
