Rock Crusher Plant EasyPLC BRX Do-More


A rock crusher (jaw crushers) is also known as “rock breakers” and is used to break up larger, more complex materials into more manageable pieces. The EasyPLC simulator rock crusher plant will show you how you can control this process through a programmable logic controller. We will be using Do-More technology to control this plant automation.
Rock Crusher Plant EasyPLC BRX Do-More
Using the five steps for PLC program development, we will discuss and show you how to program this rock crusher plant. An Automation Direct BRX Do-More PLC will be used for this application, but the general methods can be used for just about any PLC on the market. Let’s get started. Keep on Reading!

Don’t Get Caught Without These 3 PLC Requirements

If you are looking to purchase a PLC system, there are three key components that you should look for. If your current system does not contain these features, you need to replace it with one that does as soon as possible. The three most important features you should look for in your new PLC system are the open communications protocol, the ability to integrate easily with other methods, and the ability to have remote access. Without these three essential requirements, your PLC system will be far less effective and will be more expensive to operate than it needs to be.

We are all data companies that need the information for continued improvement. The industrial internet of things (IIoT) is essential, and the ability to take advantage of this starts with the hardware you specify for your PLC control. PLCs are now considered edge devices. This means that information should be able to be sent and received to the PLC controller when it is required. Keep on Reading!

Productivity 2000 Series PLC Tag Database


The Productivity Suite Software allows us to use tags in the PLC. Tags are a method for assigning and referencing memory locations (numbering systems) within the programmable logic controller. They allow a more structured programming approach and are stored within a tag database. The tag database is stored in the memory of the Productivity Series of PLCs from Automation Direct. Do not overthink tags. Tags are just names assigned to variables of any data type stored in the PLC memory.

We will now look at the tag numbering systems and database used with the Productivity 2000 controller. Let’s get started. Keep on Reading!

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!

Productivity 2000 Series PLC Online Programming


The Productivity Suite Software allows us to modify our existing program and execute the new code without stopping the scanning of the PLC. This is referred to as online programming or editing. We change the ladder logic code and when we save it to the PLC, the current scan of the PLC is held until the new code is written into the unit. It then releases the scan and our new program starts to execute. This happens in milliseconds so our process can continue to operate.

We will be taking our existing Start / Stop circuit from last time and add a Jog input using online programming. Changing the program online is a common method of programming. The documentation will also be changed during this online program change. Let’s get started. Keep on Reading!

EasyPLC Simulator Robotic Cell BRX Do-More 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 BRX Do-More PLC and the Do-More Designer 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. Modifications of the EasyPLC Robotic Cell will include controls for this operation. Using the five steps for program development, we will show how this sequencer is programmed. Let’s get started.
