mb2hal & ethercat master on same rj45 port

someone have never try it ... some special config on to ethercat config file? .... because never find port number only mac adress and ip adress on that file .... so not sure can work.

regards

Isn't MB2hal require a  RS485  connection (serial port)? In that case, you need a RS485 port (like a USB to RS485 interface) 
Ethercat master requires a network port
These two interfaces are totally different

@rodw ... I use mb2hal from year .... most time tcp-ip .... now the problem is that  I have only 1 cable avaiable ... So I think I can configure same rj45 port with 2 different ip adress ... other side I use a managed switch for to obtain 2 different cable ....but I ask here before to loose too mutch time to try for discover ethecat lcnc or mb2hal not permit these ......
