3.5.4 System logical device
The Ctrl logical device contains logical nodes that model UR power system devices: breakers, switches, CTs, and VTs, and
including interface to these such as AC inputs and contact I/O.
The System logical device is available when the Advanced IEC 61850 option is purchased with the UR device.
3.5.4.1 Logical node zero (LLN0)
LLN0 is instantiated in all UR family devices implementing the System logical device.
