Hello,
Big issue with my LOGO!8 Webserver :

I use the annual scheduler for switching on and off lights.
The settings are :
1 - range of use (for exemple from year 2000 to year 2099)
2 - Day/month of start and day/month of stop.

The issue is that with the webserver, i can change only the parameters 2 (Day/month of start and day/month of stop) but not the range of years.
When I change one of these accessible parameters, the year of end is automatically set to 2000, that mean that the clock definitely becomes unavailable because there is no mean to change the year of end from the web server.
As my customers only have the web server to access their lighting system, their annual clock will become unusable as soon as they will change any accessible parameters (days and months) into the application.
Could you help me please ?

Thank you very much

Stéphane

By a weekly timer you can configure only the time for start / stop and the weekdays. The year is not possible.

Do you want the year also set yet, you need to combine a yearly timer with a weekly timer.

Good morning IXO65,

Looking at the box (see attached picture) and at the documention, it seems that the clock I use (not weekly but yearly) allow to set the day and month of swithing On and OFF.

That is working in the LOGOSOFT COMFORT simulation.

The issue is the date of end (red circle on the picture) that automatically change (come back to 2000) when I change the time (month or day).

I use 5 of these cloks to set the holiday dates of my customer (during this time, the output do not allow the light to be switch ON).

Thanks for your help

Hi.

Find attached a simplified version.
See if you get the same bad result with the attached..
test first then make changes as needed.

Please report your results in detail.

Good luck.

@William_B,

the wants to change the year on/off, not the time on/off.

Hello mexixo,

I'm sorry because I had probably understood something wrong.

The parameter switch-on year and switch-off year year you can use by the Web server only via LOGO! variable change . See Appendix.
You must assign the two parameters in the Logo by

Tools> VM assignment parameters.

My dear friend - please review:

The issue is the date of end (red circle on the picture) that automatically change (come back to 2000) when I change the time (month or day).

My understanding is ** When the month / day is changed, then also the year change. **

Your published solution should however be a positive way to hold the year settings to the values that it need to be.

Dear William,

Please find attached my test report.

I surely made a mistake somewhere but I really do not see where.

Thank you very much for your help.

Stéphane,

A very detailed report! Thank you very much!!

I also do not see any problem with how this has been done.
It is beyond anything I can help you with. I suggest you make a formal request for help with Siemens (please).

My friend ixo65 has made a contribution that is worth looking at. Even if the user do not change the year - at least the year can be forced to the number you want it to be.

Good luck!

Thank you IXO65,

Your solution allow the user to set the year by the web server. It is a good solution. Thank you very much.

The only issue is that the user will have to change the parameters on two different places : day and month on the web site screen and year on the variable list.

It's a pity that we cannot set a customized name for the variable that could allow to manage all the data from the variable list.

Oh, now I know what you mean. This is clearly a mistake of the web server.

Look at times the video in the attechment to. There you will see that you can change the annual figures also via the web server again.

The program, which is attending, you can see how you can program it so.

Is there a way to make PLC code as to make the year setting fixed?
In other words to make use the V-memory but write fixed values to it.
I have tried but failed.

This may help resolve the issue. (thanks)

Thanks a lot to both.
