Within weeks of announcing the ‘OPC UA including TSN down to field level’ initiative, the rapid engagement of leading automation suppliers proves the resonance of this initiative with the emerging needs of the automation users. Committed contribution to the initiative reads like a “Who’s Who�? of leading suppliers, including ABB, BECKHOFF, Bosch-Rexroth, B&R, Cisco, Hilscher, Hirschmann, Huawei, Intel, Kalycito, KUKA, Mitsubishi Electric, Molex, Omron, Phoenix Contact, Pilz, Rockwell Automation, Schneider Electric, Siemens, TTTech, Wago, Yokogawa.
Significant progress has already been made on the initiative set-up with charters created and workgroups being incorporated into the OPC Foundation organizational structure. A steering committee has been formed and is open to all members making appropriate resource commitments. This committee will manage the technical and marketing working groups and ensure alignment with OPC Foundation Technical and Marketing Control Boards.
OPC Foundation’s approach to several of the existing fieldbus organizations for joint work within this initiative has received positive response. Initial technical evaluation indicates that best practices from these organizations can be combined to enable critical functions like connection management, motion and safety.
Technical work should commence within the next two months with working groups open to all OPC Foundation members. Initial work will focus on the core functionality of field device communication, developing a next generation architecture and general model for devices which can be adopted as easily as possible by automation suppliers. This architecture and general model will be expanded with device-type specific functionality by specialist working groups. Extended OPC UA standardization documents will be published including test scenarios and certification procedures to ensure that the wider community can build compliant devices.
OPC UA shall be able to share a multi-vendor converged network infrastructure with other applications including the existing and updated Industrial Ethernet solutions. To achieve this goal, the TSN Profile for Industrial Automation standardized by the IEC/IEEE 60802 committee will be used and all working groups will closely align with this for TSN related specification sections.
