Section 2
Modbus data mappings
2.1
Overview
This document describes the Modbus data points and structures available in the
IED. The point lists describe 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-dependent 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.
