Only in part
There is no direct write access to the customer setting values (D200 - D27F) and the factory setting values
(D280 - D2FF). These holding registers can only be changed by way of the holding registers Customer Setting
Control and Factory Setting Control.
Coding of parameters:
Unless otherwise stated, parameters are coded in "big endian" format, i.e. the byte with the most
significant bits comes first. This applies in particular to parameters covering several holding registers.
