Panel map: default base address of the available tables, organized by object type
Note: The default base addresses listed above may not exactly match the
addressed of your system. Before using them for any related configuration,
please check the current settings of the Modbus master station in the Composer
tool.
For more information on the Composer configuration, refer to the NK8237
Installation, Configuration, and Commissioning Guide (document no.
A6V10316241).
WARNING
The convention of Modbus base addresses frequently found, namely 3xxxx for
input registers, 4xxxx for holding registers and so on, is not followed by NK8237.
Note that some tools strictly based on this convention will not work properly with
NK8237.
