data logger

[wcchung33a]

Hello

I'm quite fresh with compactrio. I try todesign the embedded data logger system to measure the voltage in solarenergy car. The compactriomust stand alone without pc and save the data in the real time controller.

I need The compactrio can wait for an operator start command from apush button and stop when the operator pushes the button again. I know the compactrio canauto run when the power on or reboot but I want to know other methods toachieve this function.  

I usethe crio-9022, ni 9104, ni 9201, ni 9263

Best regards

Andy

Hi

Autorun works OK

only in your program in the rio you should check buttons to determine when to start logging.

You could implement a digital trigger by reading a digital line ( push button ) and react when the button switches to true.

I apologize, I see now that you have an analog input module, however the same method applies, just react when you read a voltage on the line ( for example your push button could be a switch).
