IO-Link Physical Layer Tester

TEConcept has developed a IO-Link Physical Layer Tester (PLT) for devices to perform physical layer tests in accordance with the IO-Link test specification. The tester is powered by an external 48V power supply, controlled via a USB port, and features a standard M12 connector for connecting the devices under test. A PC software application queries the IODD of the device under test and automatically adapts most parameters of the test procedure to the capabilities of the device under test. The test cases are defined by XML files to which the user has access.

Would you like a reliable inspection of the electrical IO-Link interface?

With the Physical Layer Tester, you can test the signal level, bit timing, and current consumption of your IO-Link device in a standard-compliant and automated way.

Product Data Sheet

Functional Description

The PLT is based on a high-speed multi-channel A/D converter that measures voltages and currents on both the C/Q and L+ lines. For each test case, specific snapshots of signals are captured and stored. To generate these signals, the PLT contains all necessary elements, such as an IO-Link Master, adjustable voltage and current sources, line simulations, etc. These snapshots are visualized by the PC application in an oscilloscope-like view. They must be analyzed semi-automatically by taking measurements through the movement of graphical cursors linked to voltage, current, and time values. The measured data is entered/copied into predefined fields and used for an automatically generated test report.

Additional test systems for your IO-Link device project

In addition to the physical layer test, the protocol 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.
