In the paper Complex Event Processing Systems are considered. Complex Event Processing denotes algorithmic methods for making sense of events by deriving higher-level knowledge, or complex events, from lowerlevel events in a timely fashion and permanently. The survey of problems and approaches to their solutions associated with this technology that was done by the author with co-authors in their earlier paper led to the development of the mathematical model of such systems. This model is called a CEP-machine. Some properties of CEPmachines related to regular languages are considered in the paper. It is shown that for some classes of complex events that can be represented as a regular language a CEP-machine can be transformed to the automaton that is able to recognize these events.
