Industry Applications
In manufacturing lines where multiple sensors and actuators share a single network, the 170LNT71000 reduces wiring complexity. For example, a packaging facility using DeviceNet can connect up to 64 devices per segment, leveraging the multi-drop trunk topology to simplify installation. The adapter's support for 125, 250, and 500 kbit/s transmission rates allows engineers to balance speed against cable length—critical when devices are spread over 500 meters.
Installation & Setup Guidance
When integrating the 170LNT71000, use twisted pair cables as the transmission medium. Connect via the single 5-pin DeviceNet connector, ensuring proper termination at each end of the trunk. Configure the access method (CSMA/CA, Master/Slave, or P2P) according to your network's control scheme. Verify that the ambient temperature remains between 0 and 60°C in a non-condensing environment to maintain reliable operation.
Maintenance & Reliability
Periodically inspect the IP20 enclosure for dust accumulation, especially in industrial settings. Check cable connections for corrosion or looseness. Store spare units within -40 to 85°C to preserve component longevity. The adapter's lightweight design (0.15 lb) simplifies handling during replacement.
Compatibility & Integration
The 170LNT71000 is designed for the Modicon Momentum automation platform and communicates via DeviceNet protocol. It supports multi-drop trunk topology and can operate at altitudes below 16,404 feet (5,000 meters). The CRC-16 control parameter ensures data integrity across the network.
Selection Guide & Purchasing Advice

Troubleshooting & Common Issues
If devices fail to communicate, first check the transmission rate setting—ensure all nodes use the same speed (125, 250, or 500 kbit/s). Verify that the number of devices per segment does not exceed 64. Inspect the twisted pair cable for breaks or excessive length beyond 500 meters. Confirm that the 5-pin connector is securely fastened.
