the method used by the plc to write a ladder logic program is called

Because the input and output sections look so much like rungs on a ladder (-| |-( )-), this programming method is referred to as the ladder diagram. In a ladder diagram, the output is to the right and the 'power line” is to the left. The diagram for the wiring schematic of a relay circuit is representative of a ladder diagram.

Regardless of personal style, the following five programming methods are the most commonly used. Likewise, PLC programmers develop their own unique way of doing things. Each programmer has their own style and method to accomplish the job. If you are familiar with computer programming, you know the basic processes are the same. This article will discuss the advantages and briefly explore the programming methods used for PLCs. Most professionals in the industry say modular PLCs have many distinct and important advantages over fixed PLCs.

There are two main types of PLCs - modular and fixed. Originally developed to replace relay circuits, PLCs have taken on a life of their own, and working with them can be exciting and rewarding. From roller coasters at a theme park to traffic lights on Main Street, PLCs are the unseen, crucial component to automated life as we know it. Whether you know it or not, you come into contact with PLCs on a regular basis. Programmable logic controllers, or PLCs, are industrial and/or commercial computers created to run automated systems.
