What this chapter contains

This chapter contains a short description of the DeviceNet network
and the FDNA-01 DeviceNet adapter module.

DeviceNet network

The DeviceNet network has a linear bus topology. Terminating
resistors are required on each end of the trunk line. Drop lines as
long as 6 metres (20 feet) each are permitted, allowing one or
more nodes to be attached. DeviceNet allows branching structures
only on drop lines.
The maximum length of the trunk cable depends on the data rate
and on the type of the cable used (see chapter Technical data).
