EtherNet/IP Troubleshooting & Diagnostic Tools
Tools for EtherNet/IP troubleshooting and network analysis, built to find faults fast. Pinpoint dropped packets, high network load, jitter, duplicate IP addresses, and failing devices on a live EtherNet/IP network, then certify the repair with a full acceptance report. The INspektor NT is passive and feedback-free, so you can watch the network while the line keeps running.
Use them to:
- Track down intermittent faults on a live EtherNet/IP network
- Commission and certify newly installed networks
- Verify a repair before you hand the line back to production
Need around-the-clock supervision instead of one-time fault-finding? See our EtherNet/IP monitoring tools.
Where EtherNet/IP Faults Start
Most EtherNet/IP problems trace back to one of four areas. Knowing which one you are in tells you which tool to reach for.
Physical layer
Bad terminations, damaged cable, connectors, and EMI-sensitive runs.
EMC and power
Noise coupling near drives and VFDs, poor bonding, unstable 24 V.
Topology and design
Unmanaged daisy-chains, no isolation, and no test access points.
Network behavior
Multicast flooding, wrong QoS, and duplex or speed mismatches.
How to Find an EtherNet/IP Fault
- Map the network with PROscan® Active V2. Discover every device, visualize the live topology, and spot duplicate IP addresses, unexpected nodes, and missing devices.
- Analyze live traffic with the EtherNet/IP-INspektor® NT. Measure network load, packet gaps, jitter, and update times per device, passive and feedback-free, while production keeps running.
- Certify the repair. Generate a full acceptance report from the INspektor NT so the fix is documented before the line goes back into service.
