Abstract
A control system for executing an application program is disclosed herein. The control system includes a plurality of main processor modules. The control system further includes a plurality of input/output modules for providing input process data to associated ones of the plurality of main processor modules. A voting system is operative to compare the input process data associated with first and second of the plurality of main processor modules to the input process data associated with a third of the main processor modules. This results in generation of voted input process data utilized by the third main processor module in executing the application program. In certain implementations the system includes a high-speed bus for distributing the voted input process data to the first and second main processor modules, each of which also executes the application program based upon the voted input process data.
