How can I switch from daylight saving time to wintertime with LOGO!?

This can be done semi-automatically.
The deadline settings can be done easily at any time. The daylight saving time and wintertime periods can also be adapted to the individual annual deadlines.
According to the diagram the wintertime or daylight saving time setting becomes effective when both the time window condition and the date condition are "true".
If it is necessary for the switchover to be at 3 a.m., then an on/off switching delay of 3 hours per path must be used.
The preset timer makes it possible to create a time window.

Semi-automatic, deadline-independent daylight saving time/wintertime switchover

The date of the annual timers must be set each year.

The program does not change the LOGO! time, but starts the process linked with M1 one hour earlier or later. The system clock however remains set to wintertime.

The download contains the sample program described above for LOGO!Soft Comfort V2.0.


Copy the "sowi_umstellung.exe" file into a separate directory and then start it with a double-click. The LOGO! project is unpacked automatically with all its associated subdirectories. You can then open and process the unpacked project with LOGO!Soft Comfort V2.0.
