Time Sensitive Networks for Industry 4.0 Vortragssprache Englisch

The digital revolution in the manufacturing process demands a communication standard which meets the requirements of the manufacturing floor. Additional sensing technology for predictive maintenance adds new quality of service requirements to the industrial network. Managing different communication requirements for motion control, programmable logic control and predictive maintenance is the key challenge of applying the IEEE Time Sensitive Network (TSN) standard to the trends in industrial automation market. This paper discusses the characteristics of a manufacturing system built of machine tools with predictive maintenance and a handling robot with camera based safety monitor. The communication requirements of various applications in this system are mapped to TSN standard modules listed under IEEE 802.1 and IEEE 802.3. It provides a configuration example to combine the various stream classes into a profile for TSN which meets the requirement of modern production cells. The second part of the paper covers the semiconductor requirements to support a deterministic, low latency and minimum jitter networked IO system. The integration of the TSN switching layer into embedded processors is a key element to ensure the quality of service of TSN up to the application layer. Time synchronization aspects for network clock and application clock are discussed in the context of a production cell. A comparison between TSN and various Industrial Ethernet protocols provides more insight whether all legacy fieldbus protocols can be replaced by a single IEEE Ethernet standard.
