Abstract: An event manager for filtering safety and security events of a system including an event sequence list including predetermined event sequences in which each sequence includes at least one event identifier identifying a corresponding one of multiple monitored events, an event sequence array that stores a received event sequence in response to received event notifications, and a controller that stores an event identifier into the event sequence array and that determines whether the received event sequence matches at least one of the predetermined event sequences for determining a composite event and a response for each received event notification. The matching determination may be made with or without consideration of chronological order. A suspected composite event may be identified when multiple possible matches may exist, and a final composite event is ratified when only one match is found. An exception may be generated upon timeout of a timer.
