Dear malik0101.
The example from Micky is based on
NetId1 : Easy819-AC-RC
NetId2 : Easy819-AC-RCX
For the connection of both PLC's you need 2 terminating resistors at the first and last
location and a network-cable with RJ45 - connectors.
You may either use the parts from Moeller
resistor Easy-NT-R
cable Easy-NT-... with different length, for example Easy-NT-150 with length 1,5 m
or you are using standard patch cables and modify a RJ45 plug with a resistor.

Maikky
