(0)  I recently set up a S7-1200 system with a magelis HMISTU855 touch panel from Schneider Electric. All was great apart from the time sync between the PLC and HMI. I think the HMI has no battery backup to keep the time setting, so at each poer cycle it loses the time. I did not need time sync for my project but I gave it a go for future reference. I didnt manage to make it work though. I read the time from the PLC in Date_n_time format, then split it in seperate integers. In the HMI software (Vijeo designer) I set up the dialog table "Set terminal clock" function to the addresses I set up in the Datablock. I didnt do anything more in the HMI side, as time was pressing for the startup. From that crude set up though I saw that the time between the PLC and HMI was not the same, after cycling the power in the HMI, when the time sync takes place. So did anyone use that panel before, having set up the time sync successfully?

(0)  Hi there, I'm not a Magelis expert, but does the Magelis have a function to set the time? In that case maybe it's possible to obtain the actual time from the S7-1200 and set the time with some sort of scheduler for executing system functions at regular intervals. Or maybe you can use NTP and Ethernet to set the right time on both the Magelis and the S7-1200? Can the MAgelis also be NTP client? Do you have an NTP server available?
