Hi, I´m also having issues with the battery backup of the RTC. Currently finishing a project with 20 LOGO units, (12/24 RCE, 6ED1052-1MD08-0BA1). Initially no of the units was working regarding the backup of RTC after power down, after trying with 24h power on, 3 units is now "fixed" and keeping time after power down..... Does any one know if there is a battery, or a capacitor inside the unit for RTC-backup? Makes no sense if you have to charge a RTC-backup battery for more than 24h before it starts working properly! Leaving the rest of the units to bake an additional 24h before call it quits on this. ------------------------------------------------------------------------------------------ |
