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.

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.
Click PLC EasyPLC Warehouse Stacker OperationThe 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.

Productivity 2000 Series PLC First Program

We will be creating our first Productivity 2000 Series PLC program. This will be done in ladder logic. The default physical IO and PLC task management will be discussed. Previously we communicated to our productivity 2000 PLC and automatically created the hardware configuration. We also set the hot-swap feature of our physical input and output cards on the controller.
Productivity 2000 Series PLC First ProgramWe will now write our first PLC ladder logic program in our Productivity 2000 Series controller. This will be a simple start-stop circuit. We will download and then run the program, monitoring the ladder logic using the Productivity Suite software. Let’s get started.

Productivity 1000 Series PLC Math Instructions

Math instructions are used to perform mathematical calculations. The Productivity 1000 Series PLC has math instructions that can be used in a wide variety of applications. We will be looking at the Data Statistics (DATA) and the Math Editor (MATH).
Productivity 1000 Series PLC Math Instructions
The automation system that you implement may involve these instructions. As a system integrator, you will require the use of these instructions in your commissioned programs.
