Modbus data mapping

There are two types of monitoring data: digital targets and measurands. For
convenience and efficiency, the same data can be read from different data areas.
Measurands and other 16-bit values can be read either from the IR or HR (read-
only) area and digital target values from either the DI or coil (read-only) area. It is
also possible to read the status of the DIs as packed 16-bit registers from both the IR
and the HR area.
Consequently, all monitoring data can be read as consecutive blocks of data from
the IR or HR area.
The register and bit addresses are presented in the tables below. Some register
structures are presented in separate sections below.
The HR and IR values are unsigned 16-bit integers unless otherwise
specified.
