The Fraunhofer Institute for Integrated Circuits IIS is developing the IoT-Bus with IPv6 support and integrated security concept. It is a communication bus based on EIA/RS-485 and the IEEE 802.15.4 standard, which enables a secure and reliable data transmission of measured values and control commands and connectivity to the Internet of Things. The IoT-Bus forms a cross-media communication protocol and unites the two worlds of WPAN and fieldbuses without complex protocol conversion. The novel technology IoT-Bus is developed as part of the SEEDs project.
CAN Range Extender
With its data container concept it is possible to transfer various protocols. This allows the IoT-Bus to be used as a range extender. This function is already available for the CAN protocol. A packet filter can be used to select which messages are to be transferred from one CAN domain to another.
