NOTICE
Error in the case of inconsistent access to measured values
Please ensure the start offset of the register is correct when making read accesses.
Please ensure the start offset and the number of registers are correct when making write
accesses.
If a value consists of two 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.
