Abstract
A controller for executing an application program to process control information related to control elements includes one or more main processors that each run the application program; a time synchronization system that synchronizes the time clocks of the main processors; and a voting system that exchanges information between the main processors and compares the information received from the other main processors. In addition, the controller includes one or more rendezvous signals sent to and received by the main processors as well as a mechanism for updating the time clocks based on a clocking midpoint of all processor signals.
