In our latest industrial Ethernet survey, we found that our readers use a wide array of protocols. EtherNet/IP and Modbus TCP/IP figured most prominently at 70% and 62%, respectively; but standard Ethernet and Profinet were also high on the list at 28% and 21%. Add to those the currently lesser-used EtherCat, Foundation fieldbus HSE, Powerlink and Sercos III, and it’s no wonder users need devices that will help their various protocols communicate with one another.
Wireless protocols also should be figured into the mix. Of those surveyed, 37% planned to deploy wireless Ethernet within the next year, with usage expectations spread between 802.11b/g, 802.11n, WirelessHART, 802.11a, and proprietary protocols.
In a separate survey conducted this year about wireless networking, respondents told us that their wireless networks need to communicate with a wide range of Ethernet variants, plus Modbus, Profibus and Foundation fieldbus.
