Can use the signal by defining a register in SIPROTEC and write on it through profibus?

I dont remember if this is PPM (pulse per minute) or PPS (pulse per second) for this case. you must adjust the internal clock manually once (via Digsi) and then the pulse will keep the clock synchronized Hi Mike, For Pulse via binary input mythologies, can I use the sginal by defining a register in SIPROTEC and write on it through profibus, or shall I use hardware input? Thanks, ------------------------------------------------------------------------------------------ Split from SIPROTEC 7SJ80 time sync.

We use Siprotec with Sicam via ethernet and time synch with NTP. Time synch via BI has a high precision, if you use any workaround you will loose the precision, maybe it is not important for your application but you should know. in the manual for communcation you can check if it is possible to adjust the time directly via Profibus., I know that for Modbus this is possible. You have to set regularly some setpoints, which are actually the current time. This is not actually time synch, because there are not mechanism to ensure high accuracy, but normally for industry projects this is ok.
