Anybus B40 Profinet Flashing LED indicator


In Profinet, it is common to request the device flash its LED’s so operators can identify the device.
I can see that the expect flash pattern occurring on LEDA1 over the SPI interface when I trigger this from a master interface. Is there a more programmatic way to detect this? I’d like my host MCU to detect this so it can flash its own LED’s.

To answer my own question:

I finally found the Profinet IO object command, Indicate_Device (1Eh).
This solves the problem exactly.
