*1 Terminator resistors are needed at both ends of the trunk line. (121 Ω)

*2 These values may apply when a special thick cable is used as a trunk line. If a special fine cable is used, the maximum network length is 100 m or less.

I/O Allocation

The port numbers of DeviceNet slave terminal are 512 to 767 for input ports and 768 to 1023 for outputs port.
