8.1 Communication Cable
For the DeviceNet communication cable, use a dedicated 5-wire DeviceNet cable conforming to the
DeviceNet Specification. There are two types of dedicated cables: large size and small size.
(Note) Take note that if a small-size cable is used, the maximum network length becomes 100 m or less
regardless of the baud rate setting.
