Research was undertaken to gain a better understanding of Control Engineering subscribers’ applications and needs regarding industrial Ethernet.

Executive Summary

• Among those specifying, recommending, and/or buying industrial Ethernet protocols and products, 70% do so for in-plant requirements and 49% buy for OEM needs.
• The primary plant floor application for industrial Ethernet protocol(s) is supervisory control and data acquisition. About half of respondents mention diagnostic, testing, and maintenance as a primary application on the plant floor.
• Almost two-thirds of respondents are either considering or currently using Ethernet as an addition to their traditional industrial network. The majority of respondents are either currently using or planning to use Ethernet protocol on monitoring / data acquisition activities.
• Network hardware devices, PLC hardware, and PCs are the most common Ethernet connection or planned connection.
• TCP/IP (native) and EtherNet/IP are the most used or planned choice for Ethernet protocols.
• Availability of devices and ability to use Ethernet protocol for control applications are the two most important features when seeking Ethernet protocols. However, most respondents do not consider themselves experts at any of the criteria listed.
• Half of respondents started using industrial Ethernet on the plant floor within the last five years with another 38% having adopted usage over five years ago.
• For those currently using Ethernet protocol, almost all are either very or somewhat satisfied when compared to using their favorite industrial network protocol.
• Ethernet/IP followed by TCP/IP (native) had the highest amount of past and future expenditures for the prior and upcoming 12 months.
• Analog, discrete, and communications are the most widely used I/O modules among those surveyed.
• The average spending per respondent on industrial Ethernet is expected to decline by over 20% within the next year. The past twelve month average spending on industrial Ethernet was $362,645. The anticipated spending average per respondent next year was $265,671.
• Rockwell Automation Allen-Bradley products top the list of Ethernet manufacturers purchased from for Ethernet related products in the past 12 months.
• Over half of those surveyed mentioned their Ethernet installations being done internally by control, plant or operations engineers with another 14% being done by IT departments.
