(For line topology or redundant ring/MRP - Media Redundancy Protocol)
Profinet connection is made individually by means of a safe Ethernet-capable
insulation displacement connection.The colour coding of connection terminals are
matching the Ethernet cable according to Profinet (white/blue/yellow/orange).
