PLC Programming was based on Relay Logic, and Relay Logic was based on—well, the fundamentals of logic. Logic circuits are digital, so they produce outputs that arediscretein nature. This means that it’s either “True or False”, “High or Low”, “Yes or No”, “0 or 1”. Nothin...
If you're familiar with industrial automation, you probably know that Programmable Logic Controllers (PLCs) are industrial computers that can be programmed to perform specific tasks in industrial environments. To interact with them, you need to know how to program PLCs. PLC programming is a ...
First and foremost, you need to get your very own PLC to work with. Computer programming of any kind is not a spectator sport, and can only be learned by a significant investment of time and effort at the keyboard. In many ways, learning to program is like learning a new spoken or wr...
PLC programming is one of the most popular skills among automation engineers. With this skill, automation engineers can communicate with PLCs and tell them how to interact with sensors and actuators on the factory floor. So, to be able to communicate with a PLC, you first need to know the...
Advanced features such as programmable limits, diagnostics, and remote configuration are available with IO-Link devices. Learn how to connect an example IO-Link block into an actual PLC project.
Standardization has long been considered an industrial automation best practice when programming programmable logic controllers (PLCs, PACs). Implementing and documenting PLC standards is crucial to achieving the most outstanding value from this investment. Nevertheless, why does standardization bring value,...
Object-oriented programming capabilities allows more structured and modular code. Unit Testing enables speedy tests of PLC programs without the need of a real PLC. This saves days of engineering time because they no longer need to test the program at the real PLC on the shopfloor. ...
Boolean. Boolean was fine for the computer-experienced engineers, but average plant engineers and electricians understood ladder logic and could work with the 084. It didn’t take other PLC makers long to emulate the Modicon ladder logic and this mode of programming has become a fixture with PL...
picture 1. Add PLC to our project. As you can from the PLC we just added, the PLC already has some centralized IOs, but in this article, we assume that we have a part of the machine that is far away and I need to connect to thePLC, in that case, we would use a Distributed IO...
