DeviceNet Connectors
DeviceNet allows different connectors, which may be grouped into open and
sealed connectors. The open connectors are available with screw or with crimp
connectors. The sealed connectors are available in mini-style and micro-style
sizes. See '$( and 94%$(.
Figure G-4. DeviceNet Connectors
Termination of the DeviceNet Network
The DeviceNet network uses the Controller Area network (CAN) bus as the
physical layer. This requires that the trunk line of your DeviceNet network be
terminated with a resistor at each end. This terminates the signal lines.
The terminating resistor:
• Prevents reflection of communication signals on the network.
• Connects the two signal conductors.
• Must be sealed if the end node uses a sealed tee.
• Must be open if the end node uses an open-style tap.
