Program to manage 5 Compressors

hello ,

I have to control 5  Compressors  3 for boge and one for atlas copco and their sequence related to Pressure transmitter for controlling the presssure of refrigeration system. the change over between the compressors base on running hours and if any of them not healthy should be change to other.

is there any idea to start the program with s7300

the below for more information :

I need one program to manage the sequence of compressors as the below:
1- the compressor index should be change base on running hours.
2-if any compressor in not healthy should run the next one.
3- if the pressure high/low must compressor came start or stop .the compressor index should be change base on running hours.the compressor index should be change base on running hours.the compressor index should be change base on running hours.

4-if the compressor no#1 reach to stage no 4 should be locked and run the next Compressor..

your response is highly appreciated....

hello norimane,

what do you want now?

A program for an S7-300 or a program for a LOGO! ?

I think similar topics were discussed on the Forum few times.

Hello norimane,

sry, we aren't here to make program for you. This is your business. You can make your program and ask in case of some problems, then we can probably help you or point you to solution. I don't have your Money from project, sry.

I only asked because you opened your topic at the LOGO! conference.

Hello norimane,

thank you for infos about your situation, I believe if you prepare some code and then you'll have problems we can help you as I said my friend. Simply you must start your investigation and study, no other way. Good luck.
