Logical Nodes

According to the IEC 61850 model logical nodes are the building blocks of an Intelligent Electronic device
(IED). A Logical Node (LN) represents the function within a physical device; it performs some operations for
that function and is object defined by its data and methods. The users view of the logical nodes is the ICD file
of the SWT 3000. A fixed set of ICD files is provided for SWT 3000.
Since the SWT 3000 related settings (communication interfaces, CMD timers) are configured via the service
program PowerSys and thus 'outside' the IEC61850 world only a minimal set of Logical Node (LN) according to
the IEC61850 model is used for the teleprotection signaling with EN100 GOOSE communication and for super-
vision. Refer to the following tables for the major data objects of Logical Nodes used in SWT 3000.
