can be used together in the same network, as shown in the figure above.
Terminators
Both ends of the trunk line must connect to terminating resistance to decrease signal reflec-
tion and ensure stable network communications.
Communications Power Supply
The communications connectors of each node must be provided with communications
power supply through the communications cable for DeviceNet communications. Commu-
nications power supply, internal circuit power supply, and I/O power supply must all be pro-
vided separately.
1 Use only DeviceNet cables as communications cables.
2 Always connect terminators to both ends of the trunk line.
3 Do not connect lightning arresters or any devices to the network other than the 260IF Module and
DeviceNet-conforming products.
