Most of the automated metering projects procuring meters with built in IEC1107 driver and an optical port.
In this case while reading data from meters, its very difficult to process if meter is not in time synchronization with the data concentrator unit. But its possible synchronize the time between meter and DCU through IEC1107 protocol .Most of the meter support time sync facility. The sequence of steps include normal iec1107 procedure,
/?!<0D><0A> could be the first command for initiate the data read.
Then meter will respond with identification response and it may like ,
/LTA4L0506272
After that we have to give a command to enter in programming mode and command will be like
<06>041<0D><0A>
and meter will respond with an acknowledgement and after that it should follow the sequence of procedures specified by meter manufacture.
