4 Way Traffic Light PLC Program EasyPLC


Traffic lights are used just about everywhere on busy roads around the world. They can help prevent traffic accidents and keep traffic flowing smoothly in the right direction by regulating the flow of cars, trucks, and other vehicles. The most common traffic light uses red, yellow, and green lights, along with arrows or flashes to indicate which lane should proceed when the lights change from green to yellow or red. Now you can visually see the 4-way traffic light by using the EasyPLC software suite. This provides an easy way of learning PLC programming.

Using the five steps for PLC program development, we will discuss how to program this traffic light. Four traffic lights and pedestrian panels with push buttons will be used. We will be using an Automation Direct Click PLC for this application, but the general methods can be used for any PLC. Let’s get started. Keep on Reading!

BRX Do-More PLC Using Modbus IO Scanner Profile


The Do-More Designer Programming Software (2.9) or higher includes a Modbus I/O Scanner with some profiles for Modbus Server (Slave) devices. This will greatly reduce the time it takes to implement and troubleshoot communications in your projects. Modbus communications are done independent of the PLC scan time and will have little or no ladder logic for the program.

Last time we communicated to a Solo process temperature controller via Modbus RTU RS485. (twisted pair) We manually set the Modbus IO scanner, reading the present value (PV) and set value (SV) of the Solo. The writing of the set value (SV) located within the BRX Do-More controller was also done. This was all be done without using any ladder logic code. We will now use the Modbus profile in the Modbus IO Scanner to connect a Click Plus PLC to our RS485 network. Using the Modbus scanner to write and read instructions we will also show how to use the ladder logic code with our scanner. Let’s get started. Continue Reading!

EasyPLC Simulator Robotic Cell Click PLC


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 robotic cell example is one of these machines. This will demonstrate a sequencer example. In this case, an engine is lifted and placed onto a rack. The logic will step through various steps to perform the task.

We will be using a Click PLUS PLC and the Click programming software to program this EasyPLC machine simulator engine loader of the robotic cell. This will be done using Modbus TCP (Ethernet) for communications. The program will allow you to start, stop and jog the sequencer. Using the five steps for program development, we will show how this sequencer is programmed. Let’s get started. Keep on Reading!

Click PLC EasyPLC Warehouse Stacker Example


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 warehouse stacker example is one of these machines. Pallets are loaded and unloaded into the stacker machine. A maximum of 30 pallets can be stored. The stacker will work as a FIFO (First In First Out) device. This means that the pallets are stored in a sequence and retrieved in a sequence.

The Click PLC will be used to program this virtual 3D stacker machine. Indirect addressing (pointers) will be used to track the positions on the stacker to store and retrieve the pallets. Using the Click Plus PLC, we will connect to the warehouse stacking machine. This will be done using Modbus TCP (Ethernet) for communications. Using the five steps for program development we will show how this FIFO is programmed. Let’s get started. Keep on Reading!

Click PLC – EasyPLC PLC Mixer 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 industrial mixer is one of these machines. When the start pushbutton is energized it will fill up a tank until the lower level sensor is detected. The mixer blades will then be turned on until the top sensor is detected. The tank is then drained past the low sensor and the process repeats for 3 cycle times. Once the sequence is complete, the tank is completely drained and ready to start again.

The Click PLC will be used to program this virtual 3D mixer machine. A DRUM instruction will be used in the PLC for the sequencing. Using the Click Plus PLC, we will connect to the mixing machine. This will be done using Modbus TCP (Ethernet) for communications. Using the five steps for program development we will show how this is programmed. Let’s get started. Keep on Reading!

Click PLC Simple Conveyor EasyPLC


The Machine Simulator (MS) is part of the EasyPLC software suite. It has many built-in machines that can be programmed. A simple conveyor is one of these machines. This is usually the starting point for learning about the machine simulator. This conveyor example will use two digital inputs and two digital outputs. A pallet will move back and forth on the conveyor. When the pallet is detected on each end it will stop and reverse direction. If both motors are started at the same time, the motors will burn up. This will be demonstrated. The machine simulator will allow you as the programmer to make mistakes before trying your program in the physical world.

The Click PLC will be used to program this virtual machine. Using the Click Plus PLC, we will connect the simulator to the simple conveyor machine. This will be done using Modbus TCP (Ethernet) for communications. Using the five steps for program development we will show how this is programmed. Let’s get started. Keep on Reading!
