The IO-Link Spy

As the year comes to a close, many service and commissioning teams face the same question:

Which tool truly makes everyday work easier—and is still missing from many service kits?

The IO-Link Spy from TEConcept was designed precisely for this purpose. It makes IO-Link communication visible without interfering with ongoing operation, effectively serving as the modern equivalent of the classic test light for industrial communication.

Check Communication Without Disruption

The IO-Link Spy is simply clipped onto the IO-Link cable. Using capacitive coupling, the signal is captured, processed, and transferred to a PC-based software application. Throughout this process, the existing IO-Link communication remains completely unaffected.

This is a decisive advantage in service situations:
Errors that occur only sporadically or under real operating conditions can be analyzed without causing machine downtime.

Designed for Service, Commissioning, and Troubleshooting

Recorded IO-Link communication can be analyzed at multiple levels:

• Byte and frame level

• M-sequences

• Protocol and application level

Powerful filtering, search, and analysis functions make it easy to quickly isolate irregularities. This makes the IO-Link Spy equally suitable for field service technicians as well as commissioning and development teams.

A Tool That Belongs in Every Service Case

Just like the classic test light in electrical engineering, the IO-Link Spy is not a tool needed for every task—but it is invaluable when the situation demands it. For this reason, it belongs in every service case supporting IO-Link systems.

As a last-minute Christmas gift, the IO-Link Spy is not only practical but genuinely useful: a tool that makes problems visible before they become critical.
