Chapter 10 DeviceNet Communication Module AH10DNET The terminal resistors must be installed to the two ends of the trunk cable only. Since the blue wire and white wire are for signal transmission, the terminal resistor must be installed between blue wire and white wire. 10.3.5 DeviceNet Network Supply Power The network just needs one or multiple supply powers which supply the power to each piece of network equipment via the bus cable. Delta DeviceNet bus cable consists of five wires, among which the power wire and signal wire occupy two wires respectively and the left one is the shielded wire as the above figure shows.
The supply power for the bus is optional and could be a single supply power or multiple supply powers according to the actual demand. Single Supply Power Multiple Supply Powers 10-13
