The DeviceNet cable system uses a trunk/drop line topology
Round shielded cable (thick, mid and thin) contains five wires: One twisted pair (red and black) for 24V
dc power; one twisted pair (blue and white) for signal, and a drain wire (bare).
Flat cable contains four wires: One pair (red and black) for 24 dc power; one pair (blue and white) for
signal. Unshielded 4‐wire drop cable is only designed for use with flat cable systems.
