Did anyone ever get you an answer on this? I've got the same situation that I've been checking into OPTO-22 ethernet "repeaters".
So far, I haven't gotten very far short of ordering these babies in, and connecting them to my SL 5/05 and just "wingin it", like I always do.
Just curious if you had gotten anymore information, cause I'd like to know too.

Oh **** I got in a hurry again, I thought you wrote communication with Wago Ethernet to Ethernet SLC 5/05...sorry for any confusion, please disregard my post.
