X: switching device logic nodes, such as XCBR, XSWI
Y: power transformer and related function logic nodes
PRS-7000 series unit uses the corresponding logic nodes according to the functions selected by
user. For the corresponding logic nodes, please refer to the instruction manual for unit of the
specific model.
9.4.4.2 Data object
IEC 61850 7-3 defined common data types, including:
 Status information: such as SPS, INS, ACT, ACD
 Measured value information: such as MV, CMV, WYE
 Controllable status information: such as SPC, INC, DPC
 Status set values: such as SPG, ING
 Analog set values: such as ASG
 Description information: such as LPL, DPL
The PRS-7000 series unit uses the above common data types, and instantiate the specific data
objects according to the need of application functions, to meet the need of application functions.
There are the following common data objects in all logic nodes (except for LPHD):
Mod
The model of logic node. It represents the behavior mode of the logic node, such as normal,
testing and blocked.
Beh
The performance of the logic node, represents the current performance status of the logic node.
the value of the same Mod is read-only and cannot be modified.
Health
Health status, it reflects the status of the relevant software and hardware of the logic node.
NamPlt
The name plate of the logic node
