Programmable Logic Controllers: Ladder Logic and Symbology

5.0 1 Review SKU: ELPLLS0CENDuration: 60 Minutes

Ladder diagrams have been used to symbolically describe electrical control (PLC) systems for many decades. Early in the development of PLCs, it was decided to use ladder diagrams in their programming interface as well. This was done so that users of PLC systems would be able to see the program in a form that they were familiar with. Virtually all PLCs still use ladder diagrams. This course examines how PLCs use ladder diagrams to perform logic functions and the symbology involved.
