Daylight Saving time on PLC

10/16/2007 5:49 PM	Rate (0)
ET_Oscar Posts: 19 Rating: (0)	Hi! Is there any way to tell the PLC (315-2 DP) to use daylight (european) saving time? I have some operation data coming out of the PLC to a MES system on a server machine, and the dates have to be right. If the PLC doesn't do Summer/Winter time adjusts, is there any way to synchronize the PLC date and time to WinCC? I'm assuming WinCC uses Windows time, and Windows time is timezone aware. This would solve my problem. Any ideas? Many thanks in advance!

Then ,therearespecialblockstochangesummer<->winter. Check for Standart Library->Standart Blocks->Miscellaneous Blocks. There is BT_LT function. There was a FAQ on this site about changing times, but i can't find it now....
