The embedded communication module, Anybus-S for Profinet, from HMS combines a Profinet interface with IRTfunctions according to the Class C standard. The intelligent communication module is based on theERTEC-200 technology from Siemens and includes all analog and digital components for an effectiveProfinet IO interface with IRT features, including an integrated 2-port real-time switch. The physical networkconnection is made via two SC-RJ fiber optic connectors.This module is specifically targeted for use within the automotive industry. Many automobile manufacturersare using fiber optic technology in their existing Interbus installations and are now migrating to Profinet withfiber optic transmission. The introduction of Profinet is seen as a natural evolution from Interbus and will takeplace step by step over the next 5 years.
