Simple design
The SIMATIC S7-300 saves space, and it is compact and modular. It is a stranger to slot rules, and it has no need for fans. The modules are simply hung on a DIN rail and screwed on to form a rugged, electromagnetically compatible configuration. The backplane bus is already integrated into the modules: just plug in the bus connectors and you're ready to go. With the varied range of modules for the SIMATIC S7-300, centralized expansions and simple distributed structures can be configured - for low-cost spare parts management.

Efficient engineering and comfortable diagnostics
The SIMATIC S7-300 is remarkable for low-cost configuring and programming. This is guaranteed by the IEC 61131-3-compliant SIMATIC engineering tools. In addition, powerful, integrated system and process diagnostics functions boost controller availability and thus productivity as well.

A wide range of CPUs
There's everything from the entry-level CPU right up to the high-performance unit. Depending on the task, there are CPUs with integral I/O, integrated technological functions, and integrated communications interfaces. They all have one thing in common: efficient processing speed for short machine cycle times.
