Color-highlighting of Ladder Diagram components only works, of course, when the computer running the program editing software is connected to the PLC and the PLC is in the "run" mode (and the "monitor" feature of the editing software is enabled). Otherwise, the Ladder Diagram is nothing more than black symbols on a white background.
The circuit shown in Figure 1b is termed a ladder diagram. Figure 1 – Ways of drawing the same electrical circuit. With such a diagram the power supply for the circuits is always shown as two vertical lines with the rest of the circuit as horizontal lines. The power lines, or rails as they are often termed, are like the vertical sides of a ...
