Programmable Logic Controllers Programming Methods and Applications
Mostly PLC programming methods start with the basic of ladder logic, Boolean algebra, contacts, coil and all the other aspects. To get more deeply into the subjects, it will generally narrow the field of view to one particular manufacturer’s unit or mostly the more popular brands.
According to IEC 61131-3 defines two graphical and two textual PLC programming language standards.
The graphical PLC programming languages are:
1. Ladder diagram, It is a programming language that represents a program by a graphical diagram based on the circuit diagrams of relay-based logic relay. It is primarily used to develop software for PLCs that used in industrial control applications.
2. Function block diagram, it is a diagram that describes a function between input variables and output variables. A function is described as a set elementary blocks. They are connected to blocks by connection lines.
The textual PLC programming languages are:
1. Structured text, it is a high level language that is block structured and syntactically elements so different languages can be used in the same program.
2. Instruction list, it is a low level language and resembles assembly. The file format has now been
There are a lot of PLC application in industrial, such as, industrial automation, water treatment, recondition control panel, system control of air conditioner and chiller, system control of automatic loading machine, system control of the packing of goods conveyor, and many more.
