For this I have activated the PLC property daylight saving time. But it didn't work Any idea why it didn't work or how to do it? Thank you very much

Most of the time, if you just press the download button, only software changes are downloaded. Daylight saving time only adjusts the local time, not the system time. So make sure you are looking at local time. Kind regards Stefan
