how to send a stop to a DAQcard from a pressure transducer

[dave2222]

Problem,

i have two while loops running seperatly on a VI.  One controls a motor (hard wired to a DAQcard 6009) and the other recieves volts from a pressure transducer which i have calibrated (also wired to DAQcard 6009).

DAQmx read function sends the signal from the transducer to a greater than function.  which im hoping to use the signal from that to stop the port that controls the motor on the DAQcard. 

if you have any suggestions they would be greatly recieved

Hi dave2222,

to send data between two or more loops you can use queues, notifier or in your case a local variable.

hi Mike thanks for your help,

The local variable wont accept the data as it is a scale type not an array. 

I tried attaching the signal to a (data to write) function.

any other suggestions?

Hi dave2222,

can you attach your code. What about Queues?? Did you tried it?

hi mike,

not sure what my code is?  (assume you mean error code).  Just a broken wire probably cause im sending boolean to the local variable.

trying that que function now, no luck so far

Hi dave,

can you show a piece of your code?

sorry,

dont know what the code is, Do you mean error code?

Hi dave,

Mike wants to see "code" - that means your program!

Please attach your vi(s) to your message, so we can see what you have done so far...

[dave2222]

ok, thanks and sorry for the confusion.

cheers

Hi dave,

no need for locals, globals, queues whatever - just put your two tasks into one loop...

Hint:
Use shift registers for error clusters...
