I make the settings of the date and time via the menu Date/time of the control panel; I save them with Apply and OK. They are well taken into account. If I power down the OP277 (24V removed) then I power on it again, then date and time are initialized to 19 Mai 2009 and 12:00:00. Could somebody tell me how to avoid that if possible ? Thanks

So when power is lost, and come back, you will have an old date and time. One possible solution is to synchronize the Date and Time with the CPU. Here is a link which might help: how do you synchronize the date and time between an operator panel and an S7-300/S7-400 controller with WinCC flexible? Best regards, Wizard
