ETHERNET IN INDUSTRIAL USE

4.4. TSN

The term OPC UA over TSN has brought together manufacturers of proprietary industrial Ethernet solutions such as Siemens, Rockwell Automation, Mitsubishi Electric or Schneider Electric to develop pro- ducts based on the TSN standard.

TSN stands for Time Sensitive Networks and has the goal of connec- ting all layers of the pyramid from the field level to the ERP / MES level with a uniform communication technology. Various real-time extensions within the Ethernet standard allow TSN to largely replace existing proprietary Industrial Ethernet solutions. The following me- chanisms are used: • Each participant in a TSN-based communication network has its own clock, with all clocks needing to be synchronized with each other

• Priorities can be defined to influence different bandwidth and timing requirements

• The way in which 2 participants can communicate with each ot- her can be determined
