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 ...

Have you ever found yourself deep into a complex PLC program, struggling to decipher the logic behind it? Frustrating, right? Well, what if I told you there’s a powerful tool that can not only ...

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 ...

Once again, a new hack shatters the myth of the air-gapped industrial network. Researchers have devised a sneaky reconnaissance attack that drops rogue ladder-logic code onto a Siemens programmable ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...
