3.5.2 Protection (Prot) logical device
The Prot logical device contains logical nodes that model protection and protection-related functions.
The Prot logical device is available when the IEC 61850 option is purchased with the UR device.
3.5.2.1 Logical node zero (LLN0)
LLN0 is instantiated in all UR family devices implementing the Prot logical device.
