What are the electrical support PLC programming language that 5 large electrical language you will it

PLC software programming language, compared with common computer language has distinct characteristics, it is different in a high-level language, it is also different from the general assembly language, and to meet the requirements of easy to write and debug.

only supports the early PLC ladder diagram programming language and a programming language, instruction list is according to the international electrotechnical commission established five can support the PLC programming language, simple small make up today to talk about this several languages, as well as their characteristics and application.

ladder diagram language is commonly used in the PLC controller program design of programming language, it is similar to relay circuit of a programming language. Familiar for personnel engaged in electric relay control, so the ladder diagram programming language application more widely.

:

1, intuitive, vivid and practical, with electric operation schematic diagram corresponding to the

2, ladder diagram program is similar with the relay control system, easy to master electrical workers,

3, the relay use of ladder diagram is implemented by the soft component, convenient use and modify more

2, instruction list Delete ( IL）

instruction table programming language is a mnemonic similar to that of the assembly language programming language and assembly language is composed of operation code and operands.

:

1, often mnemonics are used to indicate the operation function, is easy to remember, easy to master

2, have corresponding relationship with ladder diagram, under the PLC programming software can convert some software do not have this function ( Such as: mitsubishi's GX Works2)

3, easy to operation, on the keyboard of handheld programmer USES the mnemonic representation, in the absence of the occasion of computer can realize programming design

three functional module chart, Delete ( FBD）

function module diagram language is similar to digital logic circuit of a PLC programming language, for a person with a digital circuit basis is relatively easy to grasp.

:

1, in function module, analysis to understand the control scheme is simple and easy to

2, function module is in the form of graphic expression function, intuitive is strong, has good operability

3, to scale, because of the function module chart can clearly express the function relations, make programming, configuration and commissioning time greatly reduce

4, order function flowchart Delete ( SFC）

sequence function diagram language is designed to meet the sequence logic control programming language. With graphics expression, can be simple and clear description of concurrent system and complex system of all phenomena, on the basis of the model can directly programming, so has been widely used.

:

1, in order to function as the main line, distribution in accordance with the order of the function process, clear, easy to understand user program

2, for large programs can design division, adopt a more flexible program structure, can save the time of programming and debugging time

ST)

structured text language is to use the description of the structured text to describe the application of a programming language, it is similar to a programming language of high-level languages. In the large and medium-sized PLC system, often structured text is used to describe the relationship between the different variables of the control system, complete the required function or operation.

:

1, with high-level language programming, can complete complex control algorithms

2, the demand is higher, need to have advanced computer language programming skills and knowledge of

3, because the visual and poor maneuverability, commonly used in other programming languages is difficult to achieve the user program compiled

in PLC control system design, different models of PLC programming software for more than five types of programming languages support is different, so not only to understand PLC hardware performance, also want to know the PLC type of programming language support.
