一,Ladder Diagram (LD)
Figure: Ladder Diagram ProgrammingLadder Diagram is a graphical programming language similar to electrical control circuit diagrams, intuitive and easy to understand, particularly suitable for logical control. For engineers familiar with traditional relay control circuits, Ladder Diagram is the most accessible programming method. Through DevMaster, engineers can easily draw Ladder Diagrams to implement complex logical control functions.
In Ladder Diagram, complex expressions can be used as function inputs, and a segment of ST code can be embedded within the Ladder Diagram, further simplifying the logical structure of the Ladder Diagram.

Figure: Ladder Diagram Drag-and-Drop Operations (GIF)Ladder Diagram provides flexible drag-and-drop operations, which can be used to move components or add and replace components, offering simple and convenient operations.
Ladder Diagram displays specific error messages in real-time in the variable table and editing area. When engineers correct errors, the corresponding errors and warnings are cleared. This feature helps engineers identify and fix issues more quickly.

Figure: Ladder Diagram Monitoring (GIF)After enabling monitoring, the variable table displays the values of each variable and internal members in a tree structure. In the editing area, the enabled status of segments and calculation blocks is clearly displayed, facilitating engineers to observe the program's runtime status and identify issues faster. By modifying and writing prepared values, engineers can easily simulate various scenarios to better test the program's reliabilit
二,Structured Text (ST)
Figure: ST ProgrammingStructured Text (ST) is an advanced text programming language with strong expressive capabilities, supporting IF, CASE, WHILE, FOR, and REPEAT statements, suitable for handling complex mathematical operations, algorithm implementation, and control logic.
DevMaster provides rich ST language support to help engineers efficiently write and debug code, including syntax highlighting, folding, indentation adjustment, auto-completion, and real-time error checking.

三,MacroC Scripting Language
MacroC is a lightweight scripting language compatible with G-code, seamlessly integrating with machining program development. Its rich built-in functions can cover HMI script development for various application scenarios. It supports conditional statements, branching statements, loop statements, and their nesting, easily realizing various complex business logic.
MacroC can encapsulate common functions (functions, global variables, etc.) into modules, allowing reuse across multiple files, significantly improving code reusability.
四,C/C++ Development for PLC Function Modules
DevMaster supports developing PLC functions/function blocks using C/C++, meeting the demand for ultimate performance.
