Data mapping

The process of data mapping is used for defining which Modbus registers read or write to
which inverter parameters.
Details
There are fixedly defined Modbus registers for common control and status words, which
•
are located in consecutive blocks, in order to facilitate communication with OPC servers
and other Modbus masters. In order to access all relevant data of the inverter, only a mini-
mum number of commands is required.
In addition, 24 registers are provided for variable mapping, i. e. free assignment to inverter
•
parameters.
Predefined Modbus control registers
These registers are provided with write and read access.

The cross-reference in column 2 leads to the detailed parameter description.
