I have a couple of questions regarding a system I have been tasked to commission the I/O. I have a 5771 controller with ethernet card and 2 remote i/o(Point i/o) via ethernet and a vfd (powerflex) via ethernet. My question is do I have to power up and establish communciations between every device to download to the 5771 controller. Or can I just establish comms between the 5771 and Point i/o and download. The reason I ask is the Drive has not been wired by the contractor and is 2 weeks away from completion. Drive is also been controlled via ethernet 5000 suite. Also if I have to change a IP on the 5771 is a download required to make the Change?
