Logical node prefixes

130
The IEC 61850 logical node name prefix settings are used to create name prefixes to
uniquely identify each logical node. For example, the logical node "PTOC1" can have the
name prefix "abc". The full logical node name is then "abcMMXU1". Valid characters for the
logical node name prefixes are upper and lowercase letters, numbers, and the underscore
(_) character. The first character in the prefix must be a letter. This conforms to the IEC
61850 standard.
Additional details regarding the logical node naming rules are provided in IEC 61850
standard parts 6 and 7-2. GE Digital Energy recommends that a consistent naming
convention be used for an entire substation project.
Select the Settings > Communications > IEC 61850 > Logical Node Prefixes menu item to
open the IEC 61850 logical node prefixes configuration window.
