I've got a Siemens S7 200 connected to a TP177A touch panel. Is there a way that I can can set the touch panel date and time to the PLC time of day? I am displaying the PLC date and time on the touch panel but the system time of the touch panel is different. Therefore the time stamp of an alarm is incorrect. At the moment I've got a date/time field (input/output) on the display which I can manually change to the correct date and time, but the problem is that it resets with a power down.
