Device configuration data (parameters and setting values from register

42001, as well as the "factory setting" command) are directly stored in the

EEPROM in non-volatile memory when writing via Modbus. As the write

cycles of an EEPROM are limited, the write operation with these registers

or this command must not be cyclic.
