Section 2 Modbus data mappings
2.1 Overview
This document describes the Modbus data points and structures available in the
protection relay. 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 protection relay. The unavailable, that means, unused,
data points always return value 0 when they are read. The configuration-dependent
and optional data do not overlap.
