NanoJ objects 2400h NanoJ Input and 2500h (NanoJ Output) are, like the process image, mapped to the Modbus register:
2500h with 32 x 32 bit values is mapped to the Modbus register address beginning with 2000d (BB8h) and can only be read in this way.
2400h with 32 x 32 bit values is mapped to the Modbus register address beginning with 3000d (7D0h) and can only be written in this way.
To access, commands with function codes 03h
can be used. For purposes of data consistency, the restriction that the address must be 32-bit aligned and that at least 32 bits must always be written during a write operation applies.
