A.1.3 Modbus measured variables with the function codes 0x03 and 0x04
Addressing the measured variables
You can use the Modbus function codes 0x03 and 0x04 on all the measured variables listed
below.
Note
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
.
Example: If a value consists of two registers, a read command applied in
the second register
will generate an error code. The PAC3200T will also output an error code if a write operation
ends in the middle of a multi-register value.
