Programmable logic controllers (PLCs) are used extensively throughout the world. Over time, they have advanced to become more user-friendly, efficient, smaller, and less expensive. Different types of ...

If your usual tools are the Arduino and the Raspberry Pi, you might find it surprising that the industrial world tends to run on Programmable Logic Controllers, or PLCs. You can think of a PLC as a ...

When learning ladder logic, I was told that some new PLC systems were moving to scripted programming languages. My instructor assured us that we would not need to know anything other than ladder logic ...

Basics of Ladder Logic provides an overview of the basic principles, structure, and symbols of ladder logic programming. This class introduces the components of ladder logic programming language used ...

Old habits die hard. But change is inevitable. And in this case, if proponents are right, change is on the way in the form of an open PLC programming standard known as IEC 61131-3. Promulgated by the ...

As the title suggests, I'm looking for something to help me learn the basics of PLC programming. We're looking to develop the ability to do it in-house rather than wait for a contractor to come in and ...

You can download these software on your Windows PC and practice by creating different logic diagrams. The best part of these software is that you do not require any ...

Researchers have released two new exploits that attack common design vulnerabilities in a computer component used to control critical infrastructure, such as refineries and factories. The exploits ...

Researchers have discovered a design flaw lets anyone carry out commands without authentication on software called CoDeSys, which is widely used in industrial controls. CoDeSys is an IEC 61131-3 ...

On the surface, a programmable logic controller (PLC) might seem like nothing more than a generic microcontroller, perhaps outfitted to operate in industrial settings with things like high ...
