DIN SPEC 16593

Abstract

Scope: This document focuses on basic concepts of interactions between system components, and clarifies what the concepts “service” and “protocol” stand for. As an initial document on this topic it facilitates the consensus finding within the Industrie 4.0 initiative. The scope of this RM-SA DIN specification is given by the following three determinants: 1) the DIN SPEC of the Reference Architecture Model Industrie 4.0 (RAMI4.0) (section 1.1); 2) the purpose of a reference model dedicated to service-oriented architectures (SOA) (section 1.2); 3) the value chains to be considered in Industrie 4.0 (section 1.3). RAMI4.0 dimensions Looking at the RAMI4.0 and especially the three RAMI4.0 dimensions (see Figure 2), Industrie 4.0 services shall be applicable — to all architectural aspects (RAMI4.0 Layers), — to all hierarchy levels and, hence, all types of assets (from “product”, “field device”, “control device” up to the “connected world”), and — to the whole lifetime of both asset types and asset instances. NOTE A “service” is considered as an asset itself, e.g. in order to enable service management in the same sense as the management of assets of other types. As a consequence, a service needs a specification of a manifest (service meta-data). This specification categorizes the structure and the mandatory information of such a manifest which enables service identification, discovery, orchestration and choreography.
