As I have read, POWERLINK is based on the Fast Ethernet standard. I wonder if you could tell who makes the selection of this standard before running a POWERLINK application. Is the stack by default in change of making this selection of standard?
Kind regards,

I guess, your question is how the wire speed is selected in a POWERLINK network.
The answer is that this is up to the connected devices like in any other Ethernet installation (it's actually decided by the PHY and its configuration). So, if your device supports e.g. 1 GBit/s and auto-negotiation and is connected to a pure 100 MBit/s device, it will automatically switch to 100 MBit/s mode. Connected to another 1 GBit/s device it will also use 1 GBit/s.
So, POWERLINK itself does not care about the wire speed, but the industrial components in the market are all based on Fast Ethernet.
Best regards,
Wolfgang
