技术亮点

Steindl 表示，TSN 工具箱扩展了以前的现有机制来控制以太网网络的服务质量。但是什么是不知道如何处理它们的工具呢？

这就是为什么 IEC/IEEE 60802 提供的即插即用支持是可用性的关键。集中式网络控制器配置站点，以建立安全的融合网络。客户只需说明他们对通信关系的服务质量要求。

他补充说，工业自动化市场将适应 TSN 工具箱提供的功能。IEC/IEEE 60802 安全融合网络将与 PROFINET 和 OPC UA FX 一起提供工业 4.0 所需的即插即用功能。

工厂自动化、过程自动化或运动控制，所有垂直领域都可以由这种网络和工作站处理。

IEC/IEEE 60802 规定了将通信和连接配置与 PROFINET 和 OPC UA FX 配置分开的程序。这种分离是 IT/OT 融合的先决条件。

他表示，与当今典型应用程序相比，TSN 的采用具有许多特定的应用程序优势。
“IEC/IEEE 60802 安全融合网络以及即插即用是关键，”Steindl 说。此外，使用 TSN 工具箱将推动有线和无线网络之间的互操作性。假设其他垂直领域，例如专业音频/视频，共享相同的安全融合网络。”

TSN 技术

上层工业协议支持

根据 Moxa Europe 的说法，上层工业控制协议需要采用 TSN 并将 TSN 真正集成到整个系统中。这将促进 TSN 技术的发展，企业将开发和推出越来越多的商业 TSN 相关产品和解决方案。
“在未来 1-2​​ 年内，我们认为，由于 COVID-19 大流行导致供应链中断以及材料和人力短缺的情况仍将是更大规模采用 TSN 的挑战，因为公司将更不愿意并且保守地进行新站点和新技术投资，“他们说。

Moxa 表示，当前制造业自动化和数据交换的趋势，也被称为“工业 4.0”或“工业物联网”（IIoT），是基于数字化的。通过将模拟信号、声音、图像、文本和其他信息转换为计算机可读格式，数十年来，数字化一直在改变行业。为了让制造商理解所有这些信息，数据必须从工厂车间的众多传感器和设备中传输出来，并为人类或其他机器进行处理，以便实时做出明智的决策。

在当前的 Purdue 模型中，工业自动化形成了一个金字塔，其中隔离的专用协议在不同的层中自动执行特定任务。然而，这种模式给现代工业网络带来了许多基础设施挑战。这些协议本质上讲的是不同的“语言”，当需要实时通信时，这通常会导致困难。

随着时间敏感网络 (TSN) 的出现，标准以太网现在能够提供确定性服务并集成以前被众多专用协议隔离的“自动化孤岛”。

TSN 是一组标准，可通过标准以太网实现确定性消息传递。正如电气和电子工程师协会 (IEEE) 所定义的，TSN 涉及一种网络流量管理形式，以确保端到端传输延迟的不可协商时间框架。因此，所有 TSN 设备必须相互同步时钟，并使用公共时间参考来支持工业控制应用的实时通信。

换句话说，TSN 提供了一个标准和统一的基础架构，用于在正确的时间将数据传送到正确的位置。

Steindl stated that the TSN toolbox extends the previous existing mechanisms to control quality of service for Ethernet networks. But what are tools without knowledge how to handle them?

That’s the reason why the plug & produce support provided by the IEC/IEEE 60802 is the key for the usability. Centralized network controllers configure the stations setting up the secured converged network. Customers are only required to state their quality-of-service requirements for the communication relations.

He added that the industrial automation market will adapt the features provided by the TSN toolbox. IEC/IEEE 60802 secured converged networks will provide, together with PROFINET and OPC UA FX, the plug & produce feature required by Industry 4.0.

Factory automation, Process automation or Motion control, all verticals could be handled by such kind of networks and stations.

IEC/IEEE 60802 specifies procedures for separating the communication and connectivity configuration from the PROFINET and OPC UA FX configuration. This separation is the prerequisite for an IT/OT convergence.

He stated that there are many specific application benefits that will enable adoption of TSN, versus what is possible with typical applications today.
“IEC/IEEE 60802 secured converged networks together with plug & produce are the key,” Steindl said. In addition, using the TSN toolbox will push the interoperability between wireline and wireless networks. Other verticals, for example professional audio/video, are assumed to share the same secured converged networks.”

Impact of TSN technology & timeline

“Plug & produce and interoperability between wireline and wireless networks are a precondition for smart manufacturing,” he added.
He also said that IEC/IEEE 60802 secured converged networks are addressing plug & produce. 3GPP / 5G and IEEE802.11 are addressing interoperability between wireline and wireless networks. IEC/IEEE 60802 secured converged networks specification will be available in 2023, 5G and IEEE802.11 specification at a later date.

TSN Technologies

Support by upper layer industrial protocols

According to Moxa Europe, the upper layer industrial control protocols will need to adopt TSN and truly integrate TSN into the overall system. This will enable the development of TSN technologies, and companies will develop and launch more and more commercial TSN-related products and solutions.
“In the coming 1-2 years, we believe that the situation with supply chain interruption and the shortage of materials and manpower due to the COVID-19 pandemic will remain the biggest challenges to more large scale adoption of TSN as companies will be more reluctant and conservative to do new site and new technology investment,” they said.

Moxa stated that the current trends of automation and data exchange in manufacturing, also referred to as “Industry 4.0” or the “Industrial Internet of Things” (IIoT), are based upon digitization. By converting analog signals, sounds, images, texts, and other information into a computer-readable format, digitization has been transforming industries for decades. For manufacturers to make sense of all these bits of information, the data must be transported from numerous sensors and equipment on the factory floor and processed for humans or other machines to make informed decisions in real-time.

In the current Purdue model, industrial automation forms a pyramid where isolated purpose-built protocols automate specific tasks within distinct layers. However, this model gives rise to a number of infrastructure challenges for modern industrial networks. The protocols are essentially speaking different “languages”, which often results in difficulties when real-time communication is required.

With the advent of Time-sensitive networking (TSN), standard Ethernet networks are now able to provide deterministic services and integrate the “islands of automation” that were previously isolated by the numerous purpose-built protocols.

TSN is a collection of standards that enables deterministic messaging over standard Ethernet networks. As defined by the Institute of Electrical and Electronics Engineers (IEEE), TSN involves a form of network traffic management to ensure non-negotiable time frames for end-to-end transmission latencies. Consequently, all TSN devices must synchronize their clocks with each other and use a common time reference to support real-time communications for industrial control applications.

In other words, TSN provides a standard and unified infrastructure for delivering data to the right place at the right time.
