CANOPEN NETWORK INSTALLATION
3.5
CONNECTION IN THE NETWORK
In order to interconnect the several network nodes, it is recommended to connect the equipment directly to the
main line without using derivations. During the cable installation the passage near to power cables must be
avoided, because, due to electromagnetic interference, this makes the occurrence of transmission errors
possible. In order to avoid problems with current circulation caused by difference of potential among ground
connections, it is necessary that all the devices be connected to the same ground point.
Figure 3.1: CANopen network installation example
To avoid voltage difference problems between the power supplies of the network devices, it is recommended
that the network is fed by only one power supply and the signal is provided to all devices through the cable. If it
is required more than one power supply, these should be referenced to the same point.
The maximum number of devices connected to a single segment of the network is limited to 64. Repeaters can
be used for connecting a bigger number of devices.
