4.8.7 Mapping for IEC61850 communication
The user can operate the DPOS function over IEC 61850 communications following mapping
using GR-TIEMS. Note that the DPOS 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 DPOS01 function. Figure 4.8-52
exemplifies the editing of a LN; the LN “Common Switch controller (CSWI)” is chosen for the
DPOS01 function. After the user has defined an object “DPC”, the DPOS01 logical node can be
saved with the name “CSWI” plus “LN Instance”. Create a definition of the object “DPC” in the
DPOS01 logical node. Either the SBO mode or the DIR mode can be chosen in the editing for
the LN.
