IO-LINK Physical Layer Tester

The PLT is based on a high-speed multi-channel A/D converter that measures voltages and currents on both the C/Q and the L+ line. For every test case, specific snapshot of signals are taken and stored. In order to generate these signals, the PLT includes all necessary elements, such as an IO-Link Master, adjustable voltage and current sources,  and line simulations. These snapshots are visualized in an oscilloscope-like view. They are mostly analyzed in a semiautomatic way where measurements are taken by moving graphical cursors that are linked with voltage and current values. The evaluated values are entered / copied into predefined fields and used for a automatically generated test reports.
