Need someone to program a little lighting project

Dear Mr. Computer Wizard :-)

Need help with a lighting project.

I have 4 lamps to light a room.
In the summer when it gets hot, I would like to have the lamps gradually turned off at a certain temperature.

Here is a checklist of the requirements:
- At a certain room temperature the lights should gradually go off one after another.
  --> Eg.: 30°C first light off, 32°C second off, 34°C third off, 36°C all off
- if a light is turned off, it should not go on for a certain time (Eg. ~ 1h). To protect the light bulb.
- if all of the 4 lamps are turned off, then a separate lamp should go on.
- each lamp can be turned off manually
- The lights are bound to two timer with different time settings so I can switch from one timer to another.

Tell me if and how many money units do you need to accomplish this project.

Looking forward to your answer

Are you interested?

 Dear,

 Should anyone work for you?  In this forum we do not accept money !! 

Hello Seekinganswers;

You can delete your own posts on the forum; as long as you are the author, a Delete button is available when you open the post, see the screencapture below.

On the other hand, why do you not try to program the function yourelf? As Stefano replied earlier, we are not programmers for hire on this forum. We are a community of Siemens users that gets together to provide help to programmers who are in need of a suggestion or a correction.

The logic you posted seems very basic, with a minimum of work and reading you could develop a Logo! logic that could cover your requirements. If you do and are willing to share your code here we will be happy to examine and advise.

This manual shows you how to setup, configure and wire a LOGO! unit, with a special chapter on programming instructions for the unit,and another on sample applications you can use to develop your program.

LOGO! System manual

Note that you can either purchase LOGO! Soft Comfort software (and a programming cable) to prepare and download the program from a PC, or you can program it directly on the LOGO! keypad (this is kown as "the hard way", but for a logic suchnas yours it can be done).

Hope this helps,

Here's a start.

The quoted point but you have to explain more exactly ....

- The lights are bound to two timer with different time settings so I can switch from one timer to another.

 

 wow, thank you ixo65!

I need two different timer settings for the lights (Summer and Winter) so instead to manually change the timer settings two times a year, it would be easier to have a a physical switch to change from one timer to another ...

But I still do not have the explanation, for which the switchable time value is used.
For the timers that prevent the lamps from being switched on again (cooling down time) or for another purpose?

 Thank you ixo65, looks great!

The light should be on in summer during office times from 8.30 to 17.00h.

In Winter time the light should be on from 6.00 to 15.00h.

Also, the light that did go off at a certain temperature can go on again when it drops under the temperature  ...
