Hello Community,

I have a brand new PLC CPU M340 P342020, and I have a transfer program that I get from a Premium PLC. We have to make an upgrade from premiun to M340, but I'm having some issues with the real time clock, after I set the PLC Date and Time from the PC, after a couple of hours it beggans to delay some seconds from the PC Date and Time, It really concerns me because I need that the PLC to have the exact time because of the Generator Exercise, the whole reasone we are changing the Premiun to M340, is because also with the Premium we were getting the same trouble with the time, but as you all can se also with the M340 the time is no stay the same.

Is there a way that I can change some configuration or something to maintain the time in the PLC?

Thanks in advace.
