Pipeline for the use of eTSN

01

Integration

In this integration, OPC UA PubSub leverages the TSN infrastructure to ensure that data is transmitted with precision and determinism across the network. For implementation on end devices and sensors, we have developed a low-footprint version of the market leading OPC UA stack from Matrikon, adding PubSub support.

02

Data Publication

OPC UA PubSub-enabled devices act as data publishers. They gather data from sensors or processes and encapsulate it into OPC UA PubSub messages. These messages are then published onto the network, usually through Ethernet connections.

03

TSN Network Components

Within the TSN network, network switches and routers play a critical role. They must support TSN standards to provide TSN features. TSN mechanisms such as time synchronization, time-aware shaping, and scheduling are implemented within these network components. Several vendors now provide TSN switches.

04

Time Synchronization

IEEE 802.1AS, also known as Precision Time Protocol (PTP), is used for time synchronization in TSN networks. PTP ensures that all devices on the network share a common and highly precise time reference. This is crucial for ensuring synchronized data transmission. As part of eTSN, we have developed an own PTP implementation for better portability to different hardware, including wireless components.

05

Data Subscription

Devices or applications that need specific data subscribe to OPC UA PubSub messages. These data subscribers specify their areas of interest and the types of data they want to receive.

06

Deterministic Data Transfer

TSN mechanisms like time-aware shaping and scheduling come into play to guarantee that data packets reach their destinations within specified time bounds. This deterministic behavior ensures that critical data arrives on time, meeting the real-time requirements of industrial applications.

07

Data Processing

Once data subscribers receive the data, they can process it as needed for control, monitoring, analytics, or further distribution within the industrial automation system.

08

System Testing

The test suite is based on an Intel i210 NIC and Linux platform and acts as TSN device in the network. It provides benchmarking capabilities for time synchronization accuracy (up to 8 devices), scheduled traffic diagnosis, network jitter, 8 types of traffic class generator, network latency and packet drop analysis.
