Today, the connection from the sensor device to the embedded cloud takes place via real-time data communication, on sensor and edge level - for example Industrial Ethernet or fieldbuses - and gateways , which provide the transformation of real time data into the informational area.
In the future Ethernet-based real time traffic will be converted into Ethernet based TSN (Time Sensitive Network, IEEE 802.1) and OPC UA or similar standards and the interfaces between IT and OT are beginning to merge, allowing a seamless connection and communication.
TSN recently closed the missing real-time capability gap of Ethernet. It is an official IEEE extension to Ethernet, and allows for converged Ethernet-based networks, where time-synchronized, deterministic communication is possible parallel to IT traffic.
This is indispensable for time-critical machine control and processes.
The TSN specifications (IEEE 802.1) guarantee real-time, delivery of data in industrial environments, such as machine control applications in production processes from the sensor to the cloud. TSN offers guaranteed latency and quality of service (QoS) with time synchronization.
OPC-UA, a vendor independent, widely accepted and standardized Machine-to-Machine (M2M) Software protocol allows to seamlessly connect a wide variety of industrial components and machines in a unified manner and finally including security and high performance real-time capabilities when running over the fully standardized TSN Ethernet as the common transport layer.
On the basis of OPC UA, the common language, and TSN, the standardized real time transport mechanism, industrial applications can be seamlessly integrated without any need of a gateway between OT (operational technology) and IT (informational technology) . Even more, computer virtualization can be used for process control in time critical applications.
That reduces not just costs, but also the need to understand all existing technologies in the future.
