3.5.2.84 Wattmetric ground fault (Watt)
This element is instantiated in the following products: D30, D60, F35, F60, L60, L90.
Table 3-134: Wattmetric ground fault data objects
3.5.3 Control (Ctrl) logical device
The Ctrl logical device contains logical nodes that model UR control and monitoring functions.
The Ctrl logical device is available when the Advanced IEC 61850 option is purchased with the UR device.
3.5.3.1 Logical node zero (LLN0)
LLN0 is instantiated in all UR family devices implementing the Ctrl logical device.
