I hate giving any attribution to ARC Advisory Group, a well respected and worthy competitor of VDC's Industrial Automation Group (legend has it that founder Andy Chatha worked at VDC in 1985), but I must concur with their recent findings that EtherNet/IP usage is growing and that it is likely the leader of Industrial Ethernet application layer network protocols in the industrial automation space.
Based on VDC's recently published Global Wireline Industrial Networking Products market intelligence, the largest share by far and away of the ~$2.6 billion in wireline networking product (i.e. connectors, cables & cordsets, device servers, gateways, routers, switches, etc.) shipments by type of network were shipped with standard Ethernet (TCP/IP, etc.).
However among networking products shipped with industrial Ethernet application layer network protocols by type, EtherNet/IP edged out ProfiNet on the worldwide basis. However ProfiNet dominated usage among networking products shipped in EMEA and, not surprisingly, EtherNet/IP dominated usage in the Americas. EtherNet/IP networking product usage edged out ProfiNet in the Asia-Pacific region based on extensive discussions with 55 of the leading wireline networking product suppliers.
I am not going to discuss or debate the technical aspects of each industrial Ethernet application layer network protocol in this blog and which one provides greater performance over another, rather I am going to simply state that our end user data collected from over 600 respondents did not provide any information that would not support our supply-side findings. Perception is reality and it appears that Rockwell Automation's dominance in providing industrial automation solutions in the Americas slightly outweighs Siemens' similar dominance in EMEA on a global scale. Both companies offer high quality and industry setting standard products and solutions. Both companies are clients of VDC Research Group, I almost wish the data showed a dead even tie, and I am pretty confident that both companies are clients of ARC.
To show that I am completely unbiased, our data shows that Cisco is the industry leader in wireline networking products followed by Belden in 2nd, Harting in 3rd place with Siemens close on their heels in 4th and Phoenix Contact rounds out the top 5 in worldwide shipments.
