In previous versions of firmware, there was an option to set the amount of retries under advanced, PLM communications... which is still there, but now if you try to set the number of retries, you get an error popup with "request failed", yet you see activity in the event viewer scrolling by.  When you check it again, the number of retries updated for the module.

can someone also clarify when someone would want to use "no retries" versus 2 or even 9 retries? Does the higher number of retries "junk up" the messages on the powerline?

Yes it does junk up things since you're potentially sending messages that aren't needed. 

Personally, retries are a bandaid to fix communication issues. If you have issues, you're better off trying to solve them instead. If you can't, that's when retries comes into play
