工业物联网（IIOT）显示了对自动化中的大数据的生成和使用的承诺，但它正在提供很少的额外。这部分是因为部署成本很高，益处不明确。这也是因为概念没有明确定义。更重要的是，通过商业IOT解决方案，不容易解决自动化的独特需求。
So just what are these demands that are not easily address with commercial IoT? They can be summarized as:
- The need for real-time communications.
- 严格遵守网络安全标准和实践。
- 能够利用新的和不断发展的标准，例如时间敏感的网络（TSN），开放平台通信（OPC）统一架构（UA）和MQTT。
- 用于云连接的路径。
- 采用基于云的自动化和IOT解决方案。
在这个问题的列中，我们将仔细研究上面列出的前三个要求。在11月的问题中，我们将讨论第四和第五个要求：利用云为下一代自动化系统。
需要实时网络
数据通信是现代一个的基础utomation. The digital age first welcomed fieldbus and then Ethernet, bringing device-to-controller and controller-to-controller connectivity. Deterministic—that is, predictable—performance is essential and real-time requires additions to the Ethernet specification. Note the word “additions.” If the nirvana of plant-floor to top-floor communications is to be successfully reached, a real-time solution has to be compatible with raw Ethernet.
已经开发出来的几种实现和工业以太网已成为现代自动化系统背后的驱动力之一。但是，有几个版本的工业以太网，均不兼容;这导致与现场总线相同的解决方案多样化。
由于结果，用户通常会发现自己在特定的通信宇宙内捕获。这并不是本质上的糟糕，因为所有供应商都支持产品范围 - 来自现场设备的顶部设备逻辑控制器（PLC）和指定控制系统（DCSS） - 那么提供出色的结果。然而，两个困难的结果：第三方必须支持所有宇宙和最终用户没有开放的领域来处理。
Hilscher realized that the market needed to support all universes equally, so a flexible adapter solution was developed. The company launched its own family of netX chips that enable a product to be configured for any popular protocol via a simple configuration change. Gateways and adapters, like the netTAP and cifX PC card families, offer single-solution interfaces capable of serving all protocol universes, whether built into a device by the OEM or implemented in the field by the system integrator or end user.
防弹网络安全
基于云的系统的开放性和透明度带来了大的安全风险。但是，存在的几种方法可用于防止恶意攻击。IEC 62443定义了一系列可设计系统的标准。Hilscher的NetX 90和Netx 4000芯片通过提供一系列保护数据完整性的机制来支持IEC 62443策略。例如，芯片架构划分在面向网络的部分和面对从属段之间。这些是逻辑隔离的，将通信功能与应用程序任务分开。如果发生网络侵入，这种隔离会限制恶意攻击的效果。
Cryptography based on FIPS 140-2 is used to support authentication and verification. Hardware-accelerated cryptography is employed in the netX chip to significantly improve I/O cycle times by reducing CPU load and memory footprint. Software upgrades cannot match the performance of this hardware-accelerated solution.
支持标准：TSN，OPC和MQTT
由于各种通信宇宙不太可能与单个协议解决方案合并，因此可能使数据传输的同步方式可能有所帮助。这是TSN的潜在前提。
TSN是供应商中性的。它是一组IEEE 802以太网子标准，用于实时以太网体系结构。TSN通过使用时间同步和网络组件共享的计划实现确定主义。通过根据时间定义队列，TSN通过交换网络保证严格的延迟（即，延迟）。TSN用户的承诺是一个常见的物理层，各种现场总线协议成为应用层问题。完整的TSN规范仍在涌现。Hilscher最新的Netx芯片已符合最新的TSN版本，并准备好完成完成完整规格。
Two standards that have been around for a couple of decades are becoming important for IIoT: OPC UA and MQTT. OPC UA, with its clever information model concept (and now with TSN included via OPC UA TSN), promises network transparency literally from plant floor to cloud. And not just for raw data but also for information (i.e., data that carries meaning). MQTT is a light messaging protocol that will also be important in this context, though probably linked with middleware products that can add the semantics needed by higher-level systems. Hilscher netX chips support both OPC UA and MQTT.
The future of automation will be profoundly different, but the changes will be evolutionary rather than revolutionary.
