3.3 Topology
All devices are connected in parallel. The bus must be terminated at each end with a 120 ohm termination
resistor. CANopen limits the number of devices per network to 64.
The maximum possible network size is limited by the data rate. For sample, at 1 Mbit/s a network size of 20
m is possible, at 50 kbit/s a network size of 1000 m. At lower data rates the network size can be increased
with repeaters. Repeaters also enable the configuration of tree structures.
