Hi,
I was looking for information on Siemens web-pages, but official response of Siemens is to keep winter time in plc all the time. My process depends on local time, so I must to know when was time change done. Synchronization time is not supporting daylight saving change.
cheers

Hi,
For DCF77 You need hardware.
There is some functions in OSCAT library
link:
http://www.oscat.de/component/jdownload ... l?Itemid=0
there You can find
oscat_basic_332_s7 Step7 library with various functions. In manual
oscat_basic333_en there is one function DT2_TO_SDT which are able to check if daylight saving time is active or not.
kind regards
