You might be able to read the time from each device using the Local_Date (56) and Local_Time (57) in the Device object (8). As for writing the time, currently the only standard method is TimeSynchronization request (UTC or Local). Perhaps some vendors permit writing to the Local_Date (56) and Local_Time (57) properties. Note that the bacts example application simply grabs the time from the PC, and broadcasts a TimeSynchronization to the network. It could be enhanced to send a unicast directly to a specific device, or even send alternate times or even send UTCTimeSynchronization request, but that has not been done yet. Best Regards, Steve |
