IO-Link Device Tester
The TEConcept IO-Link Device Tester has been reviewed and recommended by the IO-Link Quality Working Group. The test system largely automates all protocol tests. Besides the Device IODD, only a few manual settings are required for performing the protocol test, which largely runs autonomously.
As a condition for using the IO-Link word and figurative mark, the IO-Link community requires that every manufacturer who brings an IO-Link device to market submits a manufacturer’s declaration confirming the successful completion of the prescribed conformity tests.
Protocol tests, in particular, are very complex and practically impossible to perform without appropriate test equipment.
The Device Tester is powered by 24V DC, and the device is connected via an M12 connector. Control is performed using PC software.
The tests themselves are defined by included XML files. Users can add their own tests, such as range checks for parameters.
Would you like a standard-compliant protocol test for your IO-Link device?

Additional test systems for your IO-Link device project
In addition to the protocol test, the physical layer test and the EMC test are also required for full IO-Link certification (Test & Quality IO-Link Community). To achieve this goal with as little effort as possible, TEConcept offers additional diagnostic & test tools that members of the IO-Link Community can use directly to obtain the required certifications. For non-members, TEConcept, as an accredited IO-Link Competence and Test Center, carries out the certification tests.

IO-Link Physical Layer Tester
Tests the electrical interface of IO-Link devices: signal level, bit timing, and current consumption according to the IO-Link specification. Automatically generates a report — a prerequisite for IO-Link certification.

IO-Link EMC Test Master
Supports the EMC conformance testing of IO-Link devices and ensures that devices can operate free of interference even in industrial environments.

IO-Link Diagnosis Tool
Enables parameterization, process data evaluation, and device diagnostics for IO-Link devices directly on the PC — ideal for commissioning, field use, and technical support.
