Industrial Ethernet Tester

The Fluke LIQ-100-IE is a digital test instrument designed for technicians who install or maintain industrial Ethernet networks. It validates cable performance up to 10GBASE-T using frequency-based measurements and supports EtherNet/IP, PROFINET and EtherCAT protocols. The tool also displays cable length, wire map and distance to open or short faults.

Sustained Load Behaviour

The tester performs a PoE load test that verifies the actual power available from a connected switch under real conditions rather than a brief pulse. It detects the PoE class from 1 to 8 and measures delivered power to confirm the link can support the attached device continuously. Nearest Switch Diagnostics report the advertised data rate, switch name, port number and VLAN information.

Practical Interface Limits

Cable performance testing is specified up to 10GBASE-T, so links requiring higher bandwidth fall outside the verified range. The unit supports the listed industrial protocols but does not claim compatibility with other fieldbus or proprietary standards. PoE verification covers classes 1 through 8 only.

Questions about this item

How much power does the LIQ-100-IE draw when running continuous cable tests all day?

The tester performs PoE load tests up to class 8, verifying available power from the connected switch during extended use.

What cabling or switch ports must I already have for the LIQ-100-IE to function?

It requires an Ethernet link supporting up to 10GBASE-T and a switch advertising data rate, name, port number and VLAN for nearest-switch diagnostics.

Will the LIQ-100-IE work with older 100 Mbps or 1 Gbps industrial switches I keep in service?

Yes, it displays cable length, wire map and distance to faults on legacy links while still reporting the switch's advertised capabilities.
