CHAPTER 4: 3 SERIES IEC61850 GOOSE
SR3 SERIES PROTECTIVE RELAY PLATFORM – COMMUNICATIONS GUIDE
The 3 Series IEC61850 Device Configurator allows the user to build the GOOSE
transmission by dragging and dropping digital and analog values from the 3 Series logical
nodes directly into the GOOSE transmission message. The 3 Series IEC61850 logical nodes
include five General Generic Input/Output logical nodes referred to as GGIO X where "X"
represents an index (from 1 to 5 in the case of the 3 Series) used to differentiate between
different GGIO logical nodes.
The 3 Series Contact I/O, and Virtual Inputs, and the status of Logic Elements are not data
types defined within IEC61850. The GGIO logical nodes are used to map none IEC61850
data into IEC61850 as "general generic" data which is defined within the IEC61850
standard. The 3 Series Contact I/O, Virtual Inputs and the status of Logic Elements are
mapped into GGIO2, 3 and 4 respectively.
Let's take a moment to examine this further before moving on. We will take Virtual Inputs
as our example:
