The infrastructure components for data transmission via the CANopen and DeviceNet protocol are now available from Phoenix Contact with DNV approval. The converters, repeaters, segment couplers, and bridges based on fibre optic technology can therefore also be used in shipbuilding and offshore applications. With these components, important requirements such as segmentation, network expansion, and electrical isolation can be implemented. Almost any network structure is therefore possible. Transmission media such as modem or DSL paths, wireless connections or Ethernet networks can be used as an alternative. Even different data rates in both segments are not a problem.
