I am sequencing 13 solenoid valves to collect CO2 concentration readings from composting vessels using a gas analyzer. Each valve will be selected one at a time. After each one is selected, there needs to be a delay of about 10 seconds to flush out the gas from the previous composting vessel that was sampled, and then there needs to be a delay of another 10 seconds to sample each composting vessel and to log it into its corressponding data file.
I am using a case structure with multiple tabs to complete each step in the sampling process. I am having difficulty reseting the elapsed time so that it starts out a zero and counts to 10 every time. It works once, but then it doesn't reset to zero. It will start first at 10 seconds and count to eleven, then it will start at 9, then 8, and then so on. I have tried using feedback from the "Time Has Elapsed" pin back to the "Reset" pin and "Auto Reset" pin, but it will not reset back to zero. How do I correct this? I have posted the VI below
