What happens if two devices share the same Node Address on DeviceNet?

Duplicate node addresses are not allowed on DeviceNet. If two devices share the same address, the network will experience a communication fault and the devices will not operate correctly.

What is the correct resistance for DeviceNet termination?

DeviceNet requires a 121‑ohm termination resistor at each end of the trunkline, installed at the ends of the cable that are not connected to a device.

Can you use an Ethernet cable for DeviceNet?

No. DeviceNet requires industrial‑grade shielded twisted‑pair fieldbus cable designed for both power and communication. Ethernet cable does not meet DeviceNet electrical or shielding requirements.

What does a solid red error light on DeviceNet indicate?

A solid red indicator typically means a critical fault such as power loss or a duplicate node address on the network.

What are Electronic Data Sheet (EDS) files?

EDS files are standardized text files that describe a device’s capabilities, parameters, and communication settings. If an EDS file is missing, RSLinx may display a red X or show the device as a generic icon.

Who developed DeviceNet?

DeviceNet was originally developed by Rockwell Automation.

How does DeviceNet differ from Ethernet?

Both DeviceNet and Ethernet use the Common Industrial Protocol (CIP), but Ethernet is significantly faster and supports modern network topologies. DeviceNet delivers both power and communication over the same cable and commonly uses a trunkline‑dropline topology, while Ethernet uses star, ring, or linear topologies and requires separate power.

Which should I use, DeviceNet or Ethernet?

Most new installations use Ethernet due to its speed, scalability, and integration with plant networks. DeviceNet remains common in legacy systems and will continue to be supported for many years.
