Dear all,
I am pursuing a project on PLC. i would be using seimens s7 and i would be only simulating the ladder program but i want a help related to valves. My project is chemical dosing in pre water treatment plant.. So the pH meters and turbidty meters take the respective values and the ladder logic brings the pH to 7 while turbidity <2 ntu... So i wanted to know which valves will give me the desired result of openin the valves according to the pH or turbidity will open in steps so that lime or alum (for pH) and polyelectrolyte(for turbidty ) is added .. And how do i program these valves
