In the field of industrial automation, the Modbus protocol has become the core standard for communication between devices due to its simplicity and wide compatibility. The Modbus function codes serve as the “instruction set” of the protocol, defining the types of commands between master and slave devices and determining the specific operations performed by the … Read more
Table instructions include the Add to Table instruction (AD_T_TBL), First In First Out instruction (FIFO), Last In First Out instruction (LIFO), Table Find instruction (TBL_FIND), and Fill instruction (FILL_N). They enable dynamic data storage, orderly extraction, precise searching, and bulk filling through standardized parameter configurations and corresponding logical triggers, significantly simplifying the programming process for … Read more
In Python development, defining classes often requires writing a lot of repetitive and cumbersome code, such as the __init__, __repr__, and __eq__ methods. While these methods are necessary, they can make the code appear bloated and increase the likelihood of errors. The introduction of the @dataclass decorator solves this problem by automatically generating these common … Read more
Memory Mapping Techniques and Application Examples in C Language In modern operating systems, memory mapping is an efficient method for file I/O operations. It allows programs to directly map files or devices into the process’s address space, enabling access to file contents as if they were memory. This technique is particularly effective when handling large … Read more
