I am considering a stepper application via Flex I/O. We have done this locally (steppers close to the PLC). Now we would like to move these steppers out next to our machine. To reduce wiring we have suggested Flex I/O. We already are using Ethernet/IP for a couple other devices.
There cannot be any delays (1-2 seconds is too long) when the stepper is told to go. I know about network collisions with Ethernet. But, this being Rockwell's Ethernet/IP (supposedly a good choice for control applications) is it reliable within my time constraints to get it to work.
If not any other alternatives without adding any specialty cards(i.e. Sercos) to the PLC?
Anybody's opinion or experience with Ethernet/IP would help.
Thanks
