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 ...

Until recently, programming and the integration of controls and motion components usually required several programming languages. Ladder logic was used for the control logic of a PLC and for the ...
