{"Image DocumentName": "PLC Programming Ladder logic is the main programming method used for PLCs [39]", "Image ImageDescription": "It is a visual and symbolic programming language that resembles relays logic diagrams. Ladder logic has been developed to mimic relay logic to reduce amount of retraining needed for engineers and trades people [39] PLC programming is called ladder logic. It\u2019s not the usual type of programming you may have seen before such as BASIC, C or assembly. It is a graphical programming language that uses graphical symbols to provide the PLC with the logical instructions needed to perform control operations. Learning how to use and implement PLCs is basically learning ladder logic. When PLCs first arrived they were made to replace relay hardware. It was preferred that a minimum about of retraining would be necessary for the engineers and trades people to operate and implement the PLCs. As a result ladder logic was developed to mimic relay logic. Ladder logic programs resemble relay logic schematics.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
