Industrial Ethernet and wireless growth are steadily growing – fieldbuses have fallen for the first time in terms of new nodes. HMS Networks is now releasing an annual analysis of industrial network market share, with a focus on newly installed nodes in global factory automation. As an independent supplier of industrial communications and industrial Internet of Things (IIoT) solutions, HMS has deep insight into the industrial networking market. The following are some of the trends they saw in the field of industrial communications in 2019.
More and more industrial equipment is constantly connecting to industrial networks. In 2019, the number of new connected nodes is expected to increase by 10%. Industrial Ethernet and wireless continue to grow rapidly, and the fieldbus will decline for the first time in 2019. This is the main finding of HMS Networks' annual research on the industrial networking market. Industrial Ethernet now accounts for 59% of new installed nodes (52% last year), while fieldbus accounts for 35% (42% last year). EtherNet/IP accounts for 15% and is still the most widely installed network, but PROFINET is also very close, accounting for 14%. Wireless technology continues to grow strongly and continues to steadily occupy 6% of the market (compared with 6% last year).
Industrial Ethernet continues to grow
Last year, HMS concluded that industrial Ethernet surpassed traditional fieldbus for the first time, and this evolution will continue to emerge in 2019. Industrial Ethernet now accounts for 59% of the global market at a steady growth rate of 20% (22% last year) (52% last year). EtherNet/IP is the largest industrial Ethernet network, accounting for 15% of the market, but PROFINET has almost no gap, now accounting for 14%. The world leader in Ethernet is EtherCAT, which accounts for 7%, Ethernet POWERLINK accounts for 5%, and Modbus-TCP accounts for 4%. These are showing steady growth.
Fieldbus is falling
For the first time in history, the fieldbus dropped by 5% (and last year was 6%) and now accounts for 35% of the newly installed nodes. The dominant fieldbus is still PROFIBUS, which accounts for 10% of the global market, followed by CC-Link, which accounts for 6%, followed by Modbus-RTU, which accounts for 5%.
Thoughts on Industrial Ethernet Growth and Fieldbus Falling
"The transition to Industrial Ethernet continues, driven by the need for high performance and integration between plant facilities and IT systems/Industrial Internet of Things (IIoT) applications," said HMS Chief Marketing Officer Anders Hansson. . "As far as installing the nodes, we saw the first real decline in traditional fieldbus. When it comes to industrial Ethernet, we have seen good growth in many networks, such as mature Ethernet/IP, PROFINET, EtherCAT, POWERLINK and Modbus- TCP, other Ethernet has also grown. This fragmented Ethernet map is very interesting, it proves that Industrial Ethernet has never been standardized on a network, just as many people first developed Ethernet-based networks in the 1990s. As predicted, just like fieldbus, various Ethernet networks have different uses depending on the industrial application."
Wireless solutions continue to grow strongly
Wireless technology has also shown steady growth, up 30% (32% last year), accounting for 6% of the entire market (6% last year). In the wireless world, wireless local area networks (WLANs) are the most popular technology, followed by Bluetooth. “More and more machine builders and system integrators are using wireless technology to implement new, innovative automation architectures. Users can reduce cabling and create new solutions for connectivity and control,” says Anders Hansson. “We also see an increase in global activity around cellular technologies (eg private LTE/5G networks) as a catalyst for smart and flexible manufacturing in the factory.”
Regional network change
In Europe and the Middle East, EtherNet/IP and PROFINET are mainstream, and PROFIBUS is also widely used. Other popular networks are EtherCAT and Ethernet POWERLINK. The US market dominates the CIP network and is clearly inclined to EtherNet/IP. EtherCAT is also constantly gaining market share. In Asia, there is no real market-leading network, but PROFINET, EtherNet/IP, PROFIBUS, EtherCAT, Modbus and CC-Link are widely used, and the Ethernet version of CC-Link IE Field is also in the market.
The study is based on the number of new installation nodes for the 2018 factory automation and is an estimate of HMS for 2019. A node is defined as a machine or device that is connected to an industrial network. The current data represents a unified view of HMS, taking into account the insights of industry peers, our own sales statistics and overall perception of the market.
