One of the core entities in the center of Industry 4.0 are cyber-physical systems. By definition, these systems require a representation in cyberspace. For that, the operations technology (OT) networks which connect the production equipment and the information technology (IT) networks from the upper factory layers will need to converge.

However, most of the industrial Ethernet standards from the current generation require proprietary hardware. This makes the convergence of networks close to impossible. The consequences are island networks that need gateways to be connected to other hierarchies.

To meet these trends, Renesas is working on realize Time-Sensitive Networking (TSN).

TSN contains all the ingredients to overcome the current limitations of the proprietary implementations. It offers a truly unified network architecture and unlike most of the current industrial Ethernet standards, it is not limited to 100Mbps. The TSN technology is defined by the IEEE 802.1 TSN task groups which combines a set of IEEE standards in order to achieve real-time deterministic behavior, while being both vertically and horizontally scalable.

Renesas is a leading supplier of industrial network solutions for the relevant industrial Ethernet standards of the current generation. Renesas will be able to combine the current generation industrial network technology with TSN.
