工业以太网在工厂自动化中的新已安装节点方面已经过于传统现场总线。这是HMS工业网络对工业网络市场的年度研究的主要发现。工业以太网现在占新安装节点的52％（去年46％），而现场总线则在42％（48）。Ethernet / IP现在是最广泛安装的网络15％，其次是Profinet和Profibus，均为12％。无线技术也强大，市场份额为6％。
现在HMS工业网络提出了他们的年度analysis of the industrial network market, which focuses on new installed nodes within factory automation globally. As an independent supplier of products and services for industrial communication and the Internet of Things, HMS has a substantial insight into the industrial network market. Here are some of the trends they see within industrial communication in 2018, also looking back on the network market share evolution during the last 5 years.
Industrial Ethernet – growth powered by IIoT
工业以太网的速度比传统现场总资本快，多年来，现在已经超越了现场总线。增长率为22％，工业以太网现在占全球市场的52％，而去年的46％。以太网/知识产权已成为最大的网络，拥有15％的市场。全球以太网竞赛者是PROFINET，EtherCAT，Modbus-TCP和以太网PowerLink。
“We have seen the transition to industrial Ethernet for a long time, but it isn’t until now that it has actually overtaken fieldbuses when it comes to number of new installed nodes,”says Anders Hansson, Chief Marketing Officer at HMS.“对工业以太网的过渡是通过对高性能的需求，工厂安装和IT / IOT系统之间的集成以及一般的工业互联网。”
Fieldbuses still fighting, but expected to decline
Boosted by a strong industry and cyber-security concerns in the industry, fieldbuses are still growing slightly. However, despite an increased growth rate at 6% (4 last year), the number of fieldbus installations are expected to decline steadily over the next few years. The dominant fieldbus is still PROFIBUS with 12% of the total world market, followed by Modbus-RTU and CC-Link, both at 6%.
Wireless is redefining the network picture
Wireless technologies are also growing by 32% (32) and accounts for 6% (6) of the total market. Within Wireless, WLAN is the most popular technology, followed by Bluetooth. “Wireless is increasingly being used by machine builders and system integrators to realize innovative automation architectures. Users can reduce cabling and create new solutions for connectivity and control, including Bring Your Own Device (BYOD) solutions via tablets or smartphones,”说Anders Hansson。
区域网络变体
In Europe and the Middle East, PROFINET and EtherNet/IP are leading and PROFIBUS is still widely used. Other popular networks are EtherCAT, Modbus-TCP and Ethernet POWERLINK.
The US market is dominated by the CIP networks, with a clear movement towards EtherNet/IP. In Asia, no network stands out as truly market-leading, but PROFINET, EtherNet/IP, PROFIBUS, EtherCAT, Modbus and CC-Link are widely used, with the Ethernet version CC-Link IE Field also gaining traction.
Looking back at 5 years of industrial network growth
A special feature in this year’s study is that HMS is looking back on 5 years of steady industrial network growth. HMS concludes that during 2017, industrial Ethernet finally passed fieldbuses in terms of market share.“在过去的5年里，工业网络的增长已经稳定，有趣的是，现在正在通过现场总线，目前使用以太网/ IP作为领先网络的52％的市场，说Anders Hansson。“尽管如此，我们的研究证实，网络市场仍然是分散的 - 用户继续要求连接到各种网络，具体取决于应用。展望未来，很明显，工业设备将越来越联系，由工业物联网和行业4.0升级。从我们的角度来看，我们非常适合随着这些趋势而增长，因为HMS都是关于“连接设备”的。“
