FAQ
Q: Can the NU-PN1 work without a PROFINET master?
A: No. It is a PROFINET I/O device. You need a PLC or master to exchange data. For standalone use, look at other NU series units.
Q: How many sensor amplifiers can I connect?
A: Up to 16 N-bus amplifiers. Keep total passing current at or below 1,200 mA.
Q: What cable should I use?
A: Cat 5 or higher UTP or STP. Keep the run under 100 m. Use shielded cable in noisy cabinets.
Q: Which update time should I set?
A: Start at 8 ms. Lower it for fast sensor response. Raise it if the network shows jitter.
Q: What should I verify on a used NU-PN1?
A: Check the RJ-45 lock, test PROFINET connection, and confirm the device name can be set. Ask for a communication test report and warranty terms.
Q: Does it support other fieldbus types?
A: Not on this model. The NU-PN1 is PROFINET only. Other NU series units cover different networks.
