You access the following device information parameters block-by-block only, e.g. read from
Offset 64001 27 Register.
NOTICE
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. SENTRON PAC will also output an error code if, for
example, a write operation ends in the middle of a multi-register value.
