Siemens presents the Simatic S7-1500 software controller with integrated safety functions. The new CPU 1507S F is designed to provide fail-safe PC-based control independently of the operating system. According to the manufacturer, it also eliminates the need for a safety controller. The combination of PC-based control and high-level language programs makes the 'Simatic S7-1500 Software Controller' suitable for special machine construction. It is operated independently of Windows. The Simatic ET 200SP Open Controller distributed controller has also been equipped with safety functionality. With the new CPU 1515SP PC F, standard and fail-safe automation tasks can now be solved in a single device. According to the manufacturer, the controller combines the functions of a PC-based software controller with visualization, Windows applications and central I/Os (input/output) in one compact device.
