partial and total indicator with counter

[devil80]

Hello guys,

I'm  implementing an application using counter timers.

I created a Vi that read a counter from a sensor of water ( each liter give me an impulse), and I use it to analyze the  partial and total  consumption of water in the laboratory.

I wants to create a front panel that the customer can observe the current consumption of water ( last 24 hours) ( last 7 days ) and ( total ).

I can read correctly for a partial last 24 hours and reset the indicator  correctly after 24 hours, but I can't do the same thing with indicator of  after 7 days because when reset the indicator of partial 1 ( last 24 hours) is resetted also the indicator partial 2  ...    while the total indicator is ok..

Do you have any ideas to solve this problem,. any suggest are precious for me..

P.s I think a good workaround is to use another counter timers to acquire the same impulse and use the same programm, but i think there is a tip to solve this  problem by programm

Thanks in advance

Dave

Hi,

Can you downconvert your vi into 2009 and upload it. Then I can take a look now.

Hi,

If you debug your code, you will see the following in your lower True/False case

  - When it's true you are changing Partial2 to zero.

  - When it's false you are changing Partial2=Partial1 but JUST after change Partial1 to zero (that's in your upper True/False cycle).

Basically you will see in Partial2 the value of Value1 or Zero.  You need to change your code to add to the value of Partial2.

PD: "Quotient & Remainder" function and "Select" functions are not doing anything in your code

Hi Nitzz

Thanks for your precious help.. here below i attached the VI with a partial and total counter..

I ask  you only an advice how to reset the total counter after 30 second because the partial counter is ok ( is able to reset after 10 seconds ) while the loop is running..

thanks again for any suggest you can give me.. 🙂

Hi,

I still couldn't run your vi as I don't have the necessary tool kits:) but i guess i figured out what was wrong with the code. I have edited your second code a bit and have attached here. Have a look. The explanations are also included in the block diagram so that you can understand the concept well.

Hello Nitzz

I read your code..it's so similar  as  "C code concept " first istruction is reset partial and second istruction reset  total keeping the shift register the same..

Thank you very much for you big help and your precious explanation..

you'll have  a good Kudos..

Good Evening
