Abstract
Measuring units measure state signals of an industrial technical process. The entirety of the state signals represents an image of the process. The measuring units transmit the state signals to a common logic unit which transmits the image of the process at least partially via a transmission medium to a computing device. The computing device executes a control program to determine at least a portion of the control state for the process and transmits the portion to the logic unit via the transmission medium. The control state includes control signals for a number of control devices. The logic unit transmits to each of the control devices the control signals intended for the respective control device. The control devices affect the process accordingly. The above steps are repeatedly executed in real-time with a cycle time in a range of milliseconds or less.
