Logical node prefixes

116
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" may have the
name prefix "abc". The full logical node name will then be "abcMMXU1". Valid characters
for the logical node name prefixes are upper and lowercase letters, numbers, and the
underscore (_) character, and 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 parts
6 and 7-2. It is recommended 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.
