Shenzhen Weiyousheng Technology Co., LTD. Is specialized in the sales of spare parts for large imported systems (distributed control systems, programmable logic controller, redundant fault-tolerant control systems, robot systems) for many years. We provide many types of industrial control components and industrial control devices. We products include ac servo motor, servo drive, Servo Amplifier, power inverter,etc.
In programming, the programmable control module is that complete a function to require the program or subroutine, or an independent program unit that can be handled by the compiler and assembler and so on, or is a part of the large software system.
The module is also known as components that can be named separately and perform certain functions independently. There are two basic features: external features and internal features. External characteristics refer to the interface between the module and the external environment (it is the way that other modules or programs routine call this module, including input and output the parameters, referenced global variables) and the function of the module.
Internal characteristics refer to the characteristics of the internal environment of the module (the module's local data and program code). Modules have various plc module types, such as the mitsubishi plc module, siemens digital input module, plc communication module, unit operation module, the calculation method module and the physical and chemical properties module and so on. And now the plc module price is relatively cheap.
