PRODUCT SETUP
Figure 5-20: Default IEC 61850 Logical Devices panel with devices middle and nodes right
To configure logical devices and nodes:
1. Right-click an entry and edit an existing device, add a new one, or move a logical node. The rest of this section
explains the window and how to perform these actions.
The default logical device categories are as follows:
• Master — Communications, including GOOSE, reports, Remote I/O, Virtual Inputs, Modbus, DNP, and setting group
control
5
• System — Power system devices: breakers, switches, CTs, VTs, and so on, including interfaces to these, such as AC
inputs, contact I/O, transducer I/O, HardFiber I/O
• Prot — Protection and protection-related functions
• Ctrl — Control and monitoring functions
• Meter — Metering and measurement functions
• Gen — FlexLogic, Virtual Outputs, non-volatile latches, FlexElements, recording (for example oscillography), security,
front panel, clock
For the Master logical device, the following logical nodes have fixed assignment:
• The LLN0 in the Master logical device, which includes setting group, GOOSE and report control blocks, and datasets
• LPHD1 — Models common issues for physical devices
• GGIO1 — For unmapped FlexLogic operands
• GGIO2 — For Virtual Input control
• GGIO3 — For RxGOOSE Inputs
• GGIO4 — For unmapped FlexAnalog operands
• LGOS logical nodes — For GOOSE subscription
The Logical Devices panel has middle and right panes. The middle pane has a list of the instantiated logical devices in the
sequence that they appear in SCL, with one device selected. The right pane has a list of the logical nodes presently
assigned to the selected logical device in lexicographic order by logical node name.
In the middle pane logical devices are shown with their product-related name, followed in brackets by their function-
related ldName, and followed by the value of their confRev. In the following example, by right-clicking and editing, the
Protection logical device has been set to instance name "Prot", the function-related name "Feeder1Prot" and the
configuration revision "2016-03-07 08:46." The text is clipped on the right if the line is longer than the available width. The
next paragraphs explain how to do this setup.
