Claim 0:
1. Controller service module running an event-driven control process in a digital twin domain for control of process entities operated in a process domain, wherein in the digital twin domain the behavior of process entities is modeled through execution of state machine models, the controller service module comprising: a memory;
an inbound interface adapted to asynchronously receive event data created with respect to process entities in the process domain and/or event data created through execution of state machine models in the digital twin domain;
an inbound buffer adapted to distribute received event data to a process cycle buffer such that every distributed event datum is represented as an input state according to an instance of a state in a relevant state machine model that maps to the event datum;
a model-based process controller adapted to read at least one input state from the process cycle buffer in processing cycles and to control selected process entities by operating a state machine execution module adapted to operate at least one relevant state machine model to reflect the input of at least one input state;
a process control module adapted to check whether the operation of the at least one relevant state machine model triggers generation of an external control command to instruct an external control operation in the process domain; and
an outbound interface adapted to output every generated external control command to at least one process entity processing the external control command.
