Abstract (en)
[origin: WO2012022362A1] The aim of the invention is to design a highly available system especially for automation technology, which allows for a platform-independent diagnosis. The device for controlling a machine comprises a first controller (1) which can process a first program code (7) for controlling, a parallel second controller (2) which can process a second program code (8) for controlling, and a synchronization device for synchronizing the first controller with the second controller. The first program code (7) is a coded program code in which operating instructions and/or data structures are coded with respect to an underlying source code (9). The second program code (8) is an uncoded program code in which operating instructions and/or data structures are not coded with respect to the source code (9). The synchronization device (3) has a coding device (12) for coding or decoding data that are communicated during synchronization according to the coding of the first program code (7) depending on the communication direction.
