A.1.10 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 values
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 PAC2200CLP will also output an error code if, for
example, a write operation ends in the middle of a multi-register value.
