Test bed consists of TSN-capable network bridges, embedded device prototype gateway boards and CIP Motion capable end nodes (PLC and Drive) with prototype firmware supporting TSN. Based on evaluation results, the text bed demonstrated feasibility of integrating EtherNet/IP into networks deploying TSN.

TSN technology is already able to address the demands of Industry 4.0 that are emerging now by maximising the use of the increasingly common gigabit bandwidth. In addition, it holds the promise of being able to evolve accordingly to meet future demands while protecting existing investments.

Most Time Sensitive Networking (TSN) standards developed so far are solutions based on Ethernet technology. However, given the nature of wireless communications, enabling TSN capabilities that maintain interoperability and compatibility with existing wired TSN standards is challenging.

The automation community is continuing to champion the introduction of OPC UA (Unified Architecture) over Time Sensitive Networks (TSN). B&R Automation provides its take on the importance of the technology, benefits for applications and how it fits with POWERLINK and other fieldbus technologies.

TSN is an important building block in meeting the targets set for Industry 4.0. But TSN-based solutions have not yet really arrived in the portfolio of automation companies. The reason for this lies in the current discrepancy between the actual goals of TSN introduction and those currently achieved.

Leveraging the combination of a real-time-capable communication technology (TSN) and real-time-capable language (OPC UA PubSub) makes it possible to realize real-time capable applications in an industrial environment based on standards and 5G technology.

Looking at the impact of Time Sensitive Networking, two key points clearly come out. First, industries should consider what open network technologies are available to help them migrate current industrial Ethernet systems to TSN compatibility. Second, any assessment needs to combine TSN and gigabit Ethernet.

Time Sensitive Networking enables the convergence of networks and systems that were previously separate for reasons of operational integrity, real-time performance, safety or security. Breaking down communication barriers between critical and noncritical systems is a foundational concept of the IIoT and Industry 4.0.

Industry 4.0 evolution demands interoperability and simplicity in communications. TSN is new generation Ethernet designed expressly to meet those requirements. A NIC card and evaluation kit are a way to get started that will simplify the network infrastructure and enable the coexistence of OT and IT.
