Abstract

A communication process and system for communicating between communication participants (S1, S2, S3, S4) that are provided for control and/or monitoring of a technological process, the communication participants connected in communication with each other by way of a bus system (B) and can be identified using their addresses. Each communication participant manages a first group of references as so-called service access points (SAPs), and for at least one of the service access points, a second group of references is managed. Access to an individual reference from this second group of references is carried out using the address of the accessing communication participant. A source address lookup table may be provided to convert participant addresses into a unique natural number corresponding to a particular reference.
