Logical node classes
Logical node groups
Logical nodes are grouped according to the logical node groups listed in Table 1. The names of logical nodes shall begin with the character representing the group to which the logical node belongs. For modelling per phase (for example switches or instrument transformers), one instance per phase shall be created; for modelling protection per zone or level, one instance per zone or level shall be created also.
Table 1 - List of logical node groups

a LNs of this group exist in dedicated lEDs if a process bus is used. Without a process bus, LNs of this group are the I/Os in the hardwired IED one level higher (for example in a bay unit) representing the external device by its inputs and outputs (process image). |
