Real-time control process for a controller of an industrial technical process, and a real-time operating process for a computing device
First Claim
1. A real-time control process for a controller of an industrial technical process, comprising the steps of:
- a plurality of measuring units measuring state signals of the process, wherein the measured state signals represent a complete image of the process;
each of the measuring units transmitting the measured state signal measured by the measuring unit to a single logical device;
the logical device transmitting at least a portion of the complete image of the process via a transmission medium to a computing device;
the logic unit receiving via the transmission medium from the computing device at least a portion of a control state for the process, wherein the control state comprises control signals for a plurality of control devices; and
the logic unit transmitting to each of the control devices the control signals intended for the respective control devices, wherein each of the control devices affects the process in accordance with the control signals transmitted to the corresponding controller.

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.
