Cable specification
The nodes on the bus system have to be wired with a fieldbus cable (DeviceNet thick or thin
cable ) complying with the DeviceNet specification (DeviceNet Adaption of CIP, Edition 1.1,
Volume Three).
Manufacturers of DeviceNet thick and thin cables for example are Belden Inc., Lapp Group,
C&M Corp., and Madison Cable Corp.
