LED Guide
- HOST LED
- Flashing green: linking to drive
- Green: drive link OK
- Flashing red: drive link lost for a moment
- Flashing orange with MODULE orange: file system error. Cycle power. Call ABB if it stays.
- MODULE LED
- Off: no power
- Flashing orange: blink mode for ID
- Flashing green: waiting for PROFINET link
- Green: normal run
- Flashing red twice per second: link is down. Check cables.
- Flashing red once per second: data does not fit the message type. Check group B and C settings.
- Red: port disabled or duplicate address. Check IP or cycle power.
- Flashing red-green: self test
- Flashing orange with HOST orange: file system error. Cycle power. Call ABB if it stays.
- NETWORK/NET LED
- Off: not on-line, or address check not done, or no power
- Flashing green: sending or receiving data

Expert Review
- The FPNO-21 is a small part with a big job.
- It turns a stand-alone drive into a network node.
- Two RJ-45 ports allow daisy chains.
- That saves switch ports and cable runs.
- Ring mode adds a path for fault tolerance.
- The LED codes are clear and fast to read.
- Setup is simple for trained staff.
- It suits both new builds and upgrades.
Manager’s Insight
- Keep one spare module per site.
- Label station names on each drive.
- Plan ring size before you add nodes.
- Long chains need a longer cycle time.
- Train techs on the LED codes.
- Fast swaps cut downtime a lot.
Warranty and Shipping
- 12-month warranty on this module.
- Orders ship in 12 to 24 hours.
- Delivery by FedEx, UPS, or DHL.
- Tracking number sent after dispatch.
FAQ
- Q: Does the module set its own network speed?
- A: Yes. It auto-detects 10 or 100 Mbit/s.
- Q: Can I link several drives in one line?
- A: Yes. Use X2 to chain units. Keep it to 50 nodes or fewer.
- Q: What does a red MODULE LED mean?
- A: The port is off, or two devices share one address. Check the IP, then cycle power.
- Q: How do I pick the right cable?
- A: Use CAT5e/6 shielded cable with RJ-45 plugs. Keep runs under 100 m.
- Q: Is a spare unit worth the cost?
- A: Yes. A spare module can restart a line in minutes.
