Node flash test
If you use more than one IO device, the "Assign device name" dialog also displays more than
one IO device. In this case, you should compare the MAC address of the device with the
indicated MAC address and select the proper IO device.
The identification of IO devices in a system is facilitated by a node flash test. To activate the
flash test:
1. Select one of the indicated IO devices from the "Assign device name" dialog box.
2. Select the flash period you want to use.
3. Press the "Flash on" button.
The LINK LED flashes on the selected IO device. If PROFINET IO is looped, both LINK LEDs will
flash.
