The Micro PLC SIMATIC S7-200 is truly in a class of its own: it’s both compact and highly powerful – especially in relation to its real-time response – it’s fast, features great communications options and comes with really easy to operate software and hardware. But there’s more to it than that: the Micro PLC SIMATIC S7-200 has a consistently modular design – for customized solutions which aren’t too large for the present but open-ended enough to be expanded anytime in the future. All this makes the SIMATIC S7-200 a real economic alternative in open loop control for the lower performance range. For any applications in automation engineering that constantly depend on innovation and optimum customer benefit. SIMATIC S7-200 delivers consistently economical solutions.
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.
An outstanding feature of the S7-400 is its modularity. The powerful backplane bus of the S7-400 and the communications interfaces that can be plugged direct into the CPU allow high-performance operation of a large number of communications lines. This enables, for example, subdivision into one communications line for HMI and programming tasks, one for high-performance and equidistant motion control components, and one "normal" I/O fieldbus. Additionally required connections to MES/ERP systems or to the Internet can also be implemented.
