hi all,
i'm new to plc programming and i was looking for some help with a project. i have 2 pumps pumping out water from a tank . one pump start at a level low level say 1 m the other pump starts at 2 m. Both of the pumps are to stop at 0.5 m level .
There are two level switches for minimum and maximum . analog input range is 4-20mA corresponding 0-4 m of water level
if one pump fails the other should cover ,pumps to change priority of starting every week and two pumps can not start at the same time.
pumps should be running on automatic.
anyone who can do this program on tia portal . thanks
