Siemens supports TSN down to the field level


Siemens supports TSN down to the field level

Siemens welcomes the initiative previously published by the OPC Foundation to further enable OPC UA adoption throughout industrial automation by extending standardization and harmonization activities for OPC UA, including TSN-enabled Ethernet networks at the field level. Siemens, as a founding and board member of the OPC Foundation, is a strong supporter of the OPC UA technology and has been active in core standardization working groups for many years.

The latest example of Siemens involvement is the foundation of the international IEC/IEEE 60802 standardization group by Siemens. This group will standardize the so called "TSN Profile for Industrial Automation (TSN-IA Profile)" to ensure a multivendor converged TSN network approach for industrial automation where different applications and protocols like OPC UA, Profinet, EtherNet/IP, etc. can share the same TSN network infrastructure. Additionally, an appropriate set of IEEE basic standards will be selected to run the different protocols on one and the same hardware base.

Joint working groups between PI and OPC Foundation members were started several months ago. These working groups are addressing topics such as the standardization of Safety over OPC UA based on Profisafe mechanisms for controller-to-controller communication, and the mapping of Profinet into the OPC UA information model for multiple use cases, e.g. asset management and diagnostics. Customers can shortly benefit from these features without waiting for TSN by simply running the OPC UA protocols on existing Profinet network installations.
