Hello Every one.Please help me in my Final Year Project.I am getting Current Data from current sensor wirelessly through myrio.If that current is more than my set point for 3 seconds than i want to isolate that part from the system ,if currrent becomes less than my set point before 3 seconds than i want no output.Please please i really need help.I am attaching my VI please I want logic for this.I already use delay,flat sequential structure but than current data becomes wrong.Please help me.

Hi Zahidkhan,

I can show you how to take care of the timing portion of it. I couldn't open your VI, but it will be best if you can implement it into your application yourself. The boolean control that I called "Condition" can be any condition you desire, in this case whether a "Current" value is less than your "Set Point".

Test it out and let me know how it works out for you.

Thanx sir..The solution you provided me is working right for any condition.Now I will interface this VI with my Vi and hardware then I will tell you again about the results.My hardware is in university.Once again thank you very much sir.But now I have checked this VI by the following condition.Please stay in contact.

Sir thank you very much for your help.I interface your VI with my current VI and hardware and is working.Sir I am working on my Final Year Project using MYRIO.But I am also new to myrio so I will need your help and ideas in future days.So please help me so that I can present the best project and much more tasks than I proposed in the last semester.Thanks Sir.

Sir I am connecting my myrio wirelessly to laptop through wifi and I am getting the data when my laptop is connected to that similar wifi,how should I access that data when I am connected with other wifi or how I can send that on internet.I want IoT in my project.Please guide me.

For a new question, please start a new thread. It will help you get more attention and better organize the forum.

Please send me the VI of seconds that you used in the above solution.

It's called "High Resolution Relative Seconds.vi", but you can do the same thing with the "Tick Count (ms)" function. You can get it, as well as other functions, by installing "Hidden Gems in vi.lib" through VIPM.
