PLC high redundancy Ethernet

Hi im going to be using 2x PM573 to do high redundancy. and the i have been told by our rep that to do this we need 2x CM579 (ethenet comication modules) but when i look in the manual (link below) it show that i can use the on board ethernet to run the high renduncy link. is this correct ?
