S7-300 is a modular small PLC system that can be used to directly control equipment and can monitor multiple next-level programmable controllers. It is also suitable for the control of medium or large control systems and can meet medium performance requirements. application.

s7-300 is aimed at small and medium-sized systems. Its module can be expanded up to 32 modules. The backplane bus is also integrated into the module. Its network connection is relatively mature and popular. There is mini and industrial Ethernet for communication and programming. Becomes simple, more selective, and can be configured and set parameters with the help of tools.

s7-400: The difference from 300 is mainly in the hot start (worst) part, and the others are basically the same. It also has an external battery power interface, which can provide backup power to the ram when the battery is replaced online.

S7-1500 is a new generation of large and medium-sized PLC, which has greatly improved the indicators of S7-300/400. It is specially designed for medium and high-end equipment and factory automation. Sufficient resources and ultra-high-speed computing processing are available to users. Speed has excellent system performance and integrates a series of functions, including motion control, industrial information security, and fail-safe functions that can realize convenient and safe applications
