EasyPLC Simulator Productivity PLC Robotic Cell


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. The logic will step through different steps in order to perform the task. In this case, an engine is lifted and placed onto a rack.

We will be using a Productivity Suite Programming Simulator to program this engine loader of the robotic cell. This will be done using Modbus TCP (Ethernet) for communications. 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!

BRX Do-More PLC High-Speed Input Counter


The BRX Do-More series of programmable logic controllers have built-in high-speed inputs. These inputs can function in Counter, Timer, or Pulse Catch modes. Every CPU will have either 6 or 10 high-speed inputs (HSI) available depending on the model. These inputs can be used for input frequencies from 0 to 250Khz. 250Khz represents 250000 input counts per second that can be coming from devices connected to your PLC like an encoder. Due to the speed of the inputs, they function on the BRX Do-More PLC asynchronous with the PLC scan time.
BRX Do-More High Speed Input Counter
We will be looking at the wiring of an incremental encoder to our BRX Do-More PLC. The A, B, and Z phases will be connected. Using the high-speed input menus in the Do-More Designer programming software we will specify the counter mode of operation. We will also scale the input so we can determine the revolutions per minute (RPM) rate. This will be monitored on our data view window. Let’s get started with the BRX Do-More PLC High-Speed Input Counter. Continue Reading!

EasyPLC Software Suite – Quick Start


The EasyPLC Software Suite is a complete PLC, HMI, and Machine Simulator. The purpose of this quick start is to help you quickly learn this software suite. The manual that comes with EasyPLC Software Suite can always be referenced when required.

We will be using the simple conveyor in the machine simulator. The EasyPLC PLC will be used to program the ladder logic for this simple conveyor. Compiling and transferring the program to the EasyPLC Virtual CPU, we will then demonstrate the control of the conveyor. An HMI will also be programmed to indicate the direction of the conveyor. Let’s get started. Keep on Reading!

PLC Learning Series – HMI – Interfacing


A human-machine interface (HMI) is present in some form for every PLC. The HMI connects a user to a machine system to exchange information or control data. This interaction with the system can be through hardware or software.

HMIs offer different people information and control in many ways for the automated system. Operators, supervisors, mechanics, electricians, engineers, and programmers all have different needs. The machine HMI(s) must provide or make the information easy for all the people who use the system.
We will now look at some of the ways that human-machine interfaces (HMI) are used in automated systems today. Let’s get started. Keep on Reading!
