Re: UDP
That was a joke I made, because your "Location" is Mars, which meant a light time transfer time, of a few seconds, for every message, which in turn would mean that a delay would be added for the built-in ACK for each and every packet if TCP is used, so a UDP-based protocol would work better, where there could be a different protocol e.g. send several packets and then ACKnowledge with a single packet for all of them, which would lessen the loss of time in a light time delay.
So I guess everyone here is not a "bit-head", and jokes are not so funny when they have to be explained, eh?

I thought it was funny enough to tell to my wife, who promptly gave me that "i'm glad you're happy, dear, but you're talking gibberish" eyebrow.

I thought it was relative. On my home planet, Tor-Poul, out inter-planetary comm's are UDP.

This is incorrect, legacy comms dropped from the L8 redundancy only
That's good to know.
That is for redundancy.

Again, you are taking a side from L8 redundancy presentation from ROKLive.
None of these are applicable for a standard L8 controller.
Do you have a link to the new stuff for standard users?

Where are you guys getting this information?
I am currently implementing dozens of L8x controllers, utilizing the onboard Ethernet Port.
Based on the post above, can anyone clarify for sure that Rockwell is not discussing the elimination of this port - along with the USB port?
I'm sure that there would be a storm of angry developers out there if Rockwell committed to the removal.
