4.2.7 Mapping for IEC 61850 communication
The user can operate the DPSY function over IEC 61850 communications† following mapping
using GR-TIEMS. Note that the DPSY function is designed for the class of “Double Point
Controller (DPC)” in the IEC 61850 standard for communication. The user should follow these
steps, each of which is discussed below:
Step1: Editing Logical Node
Step2: Mapping output data
Step3: Mapping input data
(i) Editing Logical Node
The user will need to create a logical node (LN) for the DPSY01 function. Figure 4.2-52
exemplifies the editing of a LN; the LN “Common Switch controller (CSWI)” is chosen for the
DPSY01 function. After the user has defined an object “DPC”, the DPSY01 logical node can be
saved with the name “CSWI” plus “LN Instance”. Create a definition of object “DPC” in the
DPSY01 logical node. Either the SBO mode or the DIR mode should be chosen in the editing
for the LN.

Defining SBO mode
Figure 4.2-53 exemplifies the DPSY01 logic node saved as “CSWI1”. In the SBO mode, the user
should select the following items for the “CSWI1$Pos” using GR-TIEMS:
