PLC programming languages

“

- [Instructor] Simply, PLC programming languages are used to program the automation devices within industrial field. The controllers that are used in industrial automation need to be programmed to perform certain tasks like moving products or sorting them. In industrial automation, devices are connected through PLCs that are programmed using softwares. There are five programming languages for PLC that are divided into two main sections, text based and graphical. The two common methods for PLC programming are ladder logic and block diagram. All these languages are defined by the international standard for PLC programming languages and concepts. The standard explains the format, syntax, and display for the five PLC languages available. Each language is used and best suited for certain types of applications. We will be learning the basic principles for ladder logic programming, how to read, write, assemble ladder logic. Ladder logic is one of the languages used to develop software for programmable logic controllers, PLCs, used in industrial control applications. A PLC programmer is the person responsible for coming up with the logic needed and programming the controller to solve the required task.
