Support of the new SIMATIC Open Controller

The CPU 1515SP PC is a robust, PC-based system that makes use of the new S7-1500 Software Controller. The CPU implements the function of a classical S7-1500 controller in ET 200SP design on a PC with Windows. Additional HMI functionality is provided by the CPU 1515SP PC + HMI with pre-installed WinCC Runtime Advanced. This enables both control and visualization functions in one unit (planned 01/2015).
