3.7.5 Mapping for IEC61850 communication
The user can operate the GCNT function over IEC 61850 communication following mapping
using GR-TIEMS. Note that the GCNT function is designed for the class of “Integer Status
Controller (ISC)” 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 GCNT01 function. Figure 3.7-15
exemplifies the editing of a LN; the LN “Integer Status controller (ISCSO)” is chosen for the
GCNT01 function. After the user has defined an object “ISCSO”, the GCNT01 logical node can
be saved with the name “GIGO” plus “LN Instance”. Create a definition of the object “ISCSO”
in the GGIO logical node. Either the SBO mode or the DIR mode can be chosen in the editing
for the LN.
