Modbus device information with the function codes 0x03, 0x04 and 0x10

Addressing the device information parameters
You access the following device information parameters block-by-block only, e.g. read from
Offset 64001 27 Register.
Note
Error in the case of inconsistent access to I&M data.
Please ensure the start offset and the number of registers are correct when making read
accesses and write accesses. Always read or write the entire block.
Please ensure the start offset and the number of registers are correct when making write
accesses.
If a value consists of several registers, a read command applied in the second register, for
example, will generate an error code. The PAC3200T will also output an error code if, for
example, a write operation ends in the middle of a multi-register value.
