Ann, you have hit the nail on the head by mentioning protocols like EtherCAT.  There are applications where standard Ethernet/IP can be used, but to replace the more specific bus standards like Fieldbus, you need a deterministic protocol.  These have now been developed.  In the IP realm, the increase in speed to gigabit and beyond helps mitigate some of the determinism issues.

I see a parallel here, sort of, between control and machine vision. In control there's been a gulf separating the functionality and usability of Ethernet/IP versus the control-specific protocols like EtherCAT and Ethernet Powerlink. In machine vision, there's been a parallel guilf, perhaps not so large, between  various open-sourced protocols like USB or GigE and their vision-specific versions like the very new USB3 Vision, and the not so new GigE Vision. And the gulfs all about that pesky determinism issue.
