Siemens SENTRON PAC4220 - A.1.4 Measured Variables without Time Stamp

A.1.4 Measured variables without a time stamp with the function codes 0x03 and
0x04
Addr
essing the measured variables without a time stamp
The PAC4220 Power Monitoring Device provides measured variables with or without a time
stamp.
Note
Err
or in t
he case of inconsistent access to measured values
Please ensure the start o󹪜set of the register is correct when making read accesses.
Please ensure the start o󹪜set and the number of registers are correct when making write
accesses.
If a value consists of 2 registers, a read command applied in the second register, for example, will
generate an error code. The PAC4220 will also output an error code if, for example, a write
operation ends in the middle of a multi-register value.
