Can anyone help me with this project(chemical dosing pump) using logo siemens software:

When you press the start push button, it should actuate a solenoid valve and a flowmeter and discharge 98litres of water into tank A, and also actuate another solenoid valve and a flow meter and discharge 2 litres of chemical into tank A. when the low level sensor in the tank A is activated, the counter should reset back to zero and start the process all over again.

The components: A start push button, stop push button, high level sensor and low level sensor in tank A, a flow meter and solenoid valve for water, a flowmeter, solenoid valve and pump for chemical,  a low level sensor in the chemical tank.

What information do you need

Please allow some forum usage hints:
The volunteers that answer you are not notified when you modify your postings. The changes (06/10/2023 18:55:55) made to original question is unknown to Mr. ixo65 until he discovers it.

The volunteers are not here to do your work for you. Explaining your whole process without saying what specifically we can assist with, makes it less likely for someone to get involved. Keep in mind also that pictures speak better to our international community. Consider making a diagram indicating the I/O on the diagram.

Share the program you already have. Anything you can share to speed up the team effort will be helpful.

I have observed that the an EATON processor is indicated in the electrical drawings. Do you still plan to use that? The reason is that I would suggest strongly that you use FBD instead of LAD programming when utilizing the LOGO. Also tell this forum which LOGO (part number) is planned for your solution.

Good luck.
