Apparently the IO-Link master of the S7-1500 is correct. The channel LEDs are solid green, so the configuration sent over the PCT seems fine. I do not have the three-phase network connected, since I am trying to test it without power and without a motor. But I understand that this does not affect the IO-Link bus, right? The IO-Link device is: 3RA2711-2BA00 The IO-Link master is: CM8xIQ_Link to S7-1500
