Modbus data mappings
2.1
Overview
This document describes the Modbus data points and structures available in the IED.
The point list describes a superset of all data available through the standard
configuration/s including the optional functionalities.
The majority of the Modbus data points are valid for all standard configurations. Some
data points are standard configuration or optional application dependent and thus not
available in each IED. The unavailable, that means unused, data points always return
value 0 when they are read. The configuration dependent and optional data do not
overlap.
