Specification of the bus cable
The nodes of the bus system must be wired with a fieldbus cable - a DeviceNet thick or thin cable -
according to the DeviceNet specifications (DeviceNet Adaption of CIP, Edition 1.1, Volume 3).
DeviceNet thick and thin cables for instance are manufactured by Belden Inc., Lapp, C&M Corp., and
Madison Cable Corp.
Properties of the thick cable according to the DeviceNet specifications
Note!
If you do not wish to use a thick or thin cable, the cable used must meet the requirements
given in the DeviceNet specifications.
A cable that does not meet the requirements given in the DeviceNet specifications must
not be used!
