17.2.3 Setting guidelines
Redundant communication is configured with the Ethernet configuration tool in PCM600.
Redundancy: redundant communication is activated when the parameter is set to PRP-0, PRP-1 or
HSR. The settings for the next access point will be hidden and PhyPortB will show the second port
information. Redundant communication is activated after a common write to IED is done.
