The SIMATIC S7-1200 is the controller for open-loop and closed-loop control tasks in mechanical equipment manufacture and plant construction.
Due to the compact modular design with a high performance at the same time, the SIMATIC S7-1200 is suitable for a wide variety of automation applications. Its range of use extends from the replacement of relays and contactors up to complex automation tasks in networks and within distributed structures.
The S7-1200 also increasingly opens up areas for which special electronics was previously developed for economical reasons.
Application examples include, for example:
Elevators and escalators
Material transportation equipment
Freshwater treatment plants
Wastewater treatment plants
Electricity distribution stations
Room temperature control
Heating/cooling system control
Fire protection systems
Security/access control systems
The S7-1200 is characterized by:
Easy getting started: Special starter packages including simulators and documentation facilitate familiarization.
Uncomplicated operation: Powerful standard commands which are simple to use, together with the user-friendly programming software, reduce the programming overhead to a minimum.
Real-time properties: Special interrupt functions, fast counters, and pulse outputs permit use even with time-critical processes.
