The SIMATIC ET 200 SPS Open Controller is the first controller of this type to combine the functions of a PC-based software controller with visualization, PC applications and central I/Os in a compact device.

The already installed and preconfigured SIMATIC S7-1500 Software Controller, the PC-based version of SIMATIC S7-1500, is used for control. This controller is operated independently of Windows and thus ensures high system availability. This facilitates the controller's rapid start-up and supports Windows updates and reboot during ongoing operation. Even a failure of Windows does not have any impact on the controller.
