extract numbers

Hi smm,

you should use some DAQ(mx) functions - I don't have much experience with them...

Thats what I figured. Could I ask you  one huge favor. If I attach my VI here, could you probably take a look and let me know if it looks alright. In terms of, do you think there might be an error anywhere?

I can't still test it completely becuse I haven't received the DAQ unit cables and I don't hv the hardware fixture ready.

I'm attaching the VI. Not that I expect an answer but it'll be great if anybody could tell me if there are any inherent flaws.

Thanks

 strange but the VI does not get attached. i can't see an add button. Only a browse to insert the file but nothign to attach it

Hi smm,

the "attach file" can be found under the box containing switches like "email me" and "keep the message..."!

I definitley need to tie up the Start and Stop buttons to a hardware button. Thats how they want it around here.

If you have hard Start and Stop buttons that you want to detect, then you will need extra contacts on those buttons and can wire them to the digital inputs of the DAQ card.  Whether the buttons are momentary, or latching might affect how you write the code.

If you want to replace the hard Start and Stop buttons and have your software start and stop buttons operate the hardware, then you will need to use the digital outputs and connect them to relays that replace the hard start and stop buttons.  Again, whether they are momentary or latching will affect how you program Labview.  Look at connection diagrams for the DAQ card to see what its voltage and current output can be.  Your relays will need to be compatible with that.

I need to now actually totally replace the soft start and stop button with one hard start and stop button. So the same process instead of being performed by soft buttons will be performed by hard start and stop button. I have actually posted a new msg asking the same thing.
