Hi everyone,
I am considering implementing Cypress repeater Algorithm for PLC (AN62487). My doubt is if we have 15 slaves and the repeater reaches not just 1 node next to it but 2 or more nodes and if we don't have 100% reach ability node-to-node (less say it could take 1-3 messages before one node reads correctly a message).

Seems to me the algortithim has each node operating as a repeater
requiring acknowlegement, and each node repeats to its neighbor until it
achieves acknowlegement. So the packet propagates to each nearest
neighbor until complete.

I think that with the number of hops value in the packet eliminates my doubt about the message reaching more than 1 neighbour node.
Now I am concern about the case 2 nodes send at the same time a packet. Will the packets collide and be destroyed?
Thank you again, your help is appreciated !!

Use CSMA in the protocol, much like Ethernet, to avoid collisions.
