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.
i have written the program using ladder logic, but how do i control my counter to stop the water valve, after the counter counts 5 times
