Signal and event processing engine

A signal and event processing, SEP, engine deployed on a target device of an industrial system, wherein the SEP engine includes at least one hardware processing unit, and wherein the SEP engine comprises:

• subscriber nodes adapted to receive at least one of signal and event, SE, data streams from sources of the industrial system;
• processing nodes adapted to perform signal and event processing language, SEPL, functional operations on the received SE data streams according to an SEPL script of the SEP engine, wherein the SEPL script includes predefined stateful event or data pattern matching operations to generate result SE data streams;
• and
• publisher nodes adapted to forward the generated result SE data streams to sinks of the industrial system;
• wherein the SEPL script of the SEP engine includes one or more predefined stateful functional SEPL delay operations each adapted to delay SE data streams received by subscriber nodes of the SEP engine with configurable delay time periods to generate delayed SE data streams output as result SE data streams by publisher nodes of the deployed SEP engine.
