In North America, more than 90% of control programming is done in Ladder Diagram, said Yerger. “It's great for discrete logic systems that use a lot of Boolean algebra and have a lot of limit switches ...

That comes from operators doing the wrong thing, or from automation designed the wrong way,” says Woll. “One thing I’m seeing is a trend toward state logic control and away from block-oriented ...

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 ...

Programmable logic controllers (PLCs) provide an inexpensive and noise-free method of motion control. Ladder-logic programming has been a staple for PLCs, with newer models featuring human-machine ...

In parallel with its motion control definitions, PLCopen developed standardized safety functionality that can be integrated into logic and motion applications. The ability to incorporate these safety ...

What You Need to Know. In the graduate certificate for Automation and Controls in Mechatronic Systems program, students learn about advanced concepts in programmable logic control, including sensors ...
