RAMI 4.0 based digitalization of an industrial plate extruder system: Technical and infrastructural challenges

摘要

The paper presents the major steps done for migrating the ICT-infrastructure associated to the management and control of an industrial plate extruder line to a RAMI4.0-compliant digitalized industrial system. An MES serves as a core edge where Operational Technology (OT) of the shop floor meets Information Technology (IT) located in the information and management levels of the factory. Responding to a major requirement for guaranteeing connectivity and interoperability between these two levels of the enterprise architecture, the vertical communication is created using a service-oriented MES that takes over the administrative functions from the subordinate OT components, implementing the layers 3 and 4 of the RAMI4.0-based digitalization dimension.
