3.5.6 General (Gen) logical device
The Ctrl logical device contains logical nodes that model UR FlexLogic, Virtual Outputs, non-volatile latches, FlexElements,
and recording (for example, oscillography) functions.
The Ctrl logical device is available when the Advanced IEC 61850 option is purchased with the UR device.
3.5.6.1 Logical node zero (LLN0)
LLN0 is instantiated in all UR family devices implementing the Gen logical device.
