Siemens announces support for OPC UA with TSN networks https://www.automation.com/files/pluginfiles/item_99819/field_376/siem_reg.jpg
5. December 2018 - Siemens has welcomed the initiative already announced by the OPC Foundation to enable the introduction of industrial automation into OPC UA, including TSN-enabled field-level Ethernet networks, by expanding standardization and harmonization activities for OPC UA. Siemens supports the OPC UA technology as a founding member and board member of the OPC Foundation and has been active in standardization working groups for many years.
Siemens has experience and experience in the development and standardization of industrial communication systems. Siemens actively participates in all relevant standardization bodies such as IEEE, IEC, IETF, PI, OPC F and many others, not only as editor, but also as organizer and leader of the entire working group.
The latest example of Siemens Leadership is the foundation of the international IEC / IEEE 60802 standardization group from Siemens. This group will standardize the so-called "TSN Profile for Industrial Automation (TSN-IA Profile)" to provide a converged TSN network approach for different vendors of various applications and protocols such as OPC-UA, PROFINET, EtherNet / IP etc. can share the same TSN network infrastructure. In addition, an appropriate set of IEEE base standards is selected to run the various protocols on the same hardware basis.
Siemens shares the OPC Foundation's vision to extend the scope of OPC UA to field-level communication I look forward to contributing to standardization activities in the upcoming OPC Foundation working groups focusing on information models for devices, necessary adjustments to OPC Refer to UA Core Standards, Application Profiles, and so on.
Use Cases Not Well Addressed in Today's Industrial Communications Systems, such as controller-controller-to-controller communication or device-to-top-system vertical communication through OPC UA, are initially being adopted by the market. Therefore, a few months ago, joint working groups were established between PI and OPC-F members. These work groups address 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, eg Asset Management and Diagnosis. Customers can benefit from these features soon without waiting for TSN by simply running the OPC UA protocols in existing PROFINET network installations. The PI organization brings its technological know-how to the OPC Foundation.
Communication at the field device level with cyclic I / O communication, motion control and security becomes an established ecosystem with stack providers, certification procedures, tools and more. Organizations such as PI, ODVA, and others have sought completeness and quality of specifications, conformance testing, and the maintenance of a dealer and user community.
Siemens bears responsibility to the installed base and will therefore continue to renew Profinet to protect its customers' investments and take Profinet to the next level based on TSN. The converged TSN network and the common hardware platforms for Profinet and OPC UA enable a smooth migration into the new TSN world. In addition, we ensure that with OPC UA, including TSN, the basic principles of communicating field devices, engineering workflows, conformance testing, diagnostics, etc. remain unchanged.
