STEP: ACTION

[stemag]

I'M A NEW USER OF TEST STAND (3.1) AND MY QUESTION IS, PROBABLY, VERY SIMPLE FOR YOU:

IN A STEP "ACTION" I NEED TO GENERATE, WITH LABVIEW 7.1, A SQUARE WAVE FROM THE AO0 OF MY PCI-6071E; AFTER STARTING GENERATION, I NEED TO VERIFY SOME NUMERIC LIMIT TEST AND, AFTER THAT, I NEED TO TERMINATE THE GENERATION.

THE VI I CALL IN THE "SPECIFY MODULE" USE A WHILE LOOP FOR CONTINUING GENERATION (DAQMX) SO, TO PROCEED WITH THE SEQUENCE, I HAVE TO STOP THE VI AND, THEREFORE, THE GENERATION.

I NEED SOMETHING SIMILAR A GPIB CALL, WHERE THE INSTRUMENT "LATCH" THE COMMAND I SEND IN THE STEP "ACTION" AND RETAIN THIS STATE UNTIL I WILL SEND ANOTHER GPIB COMMAND.

CAN YOU KINDLY HELP ME? I NEED URGENTLY A SOLUTION!

THANK YOU VERY MUCH IN ADVANCE

BEST REGARDS

Hi, You could split your AO generation VI in two steps, one to configure and start your task and the second to perform error checking and stop the generation.
I realized a little example, take a look at it and tell me what you think!
(Don't look too much at details... I realized it on the fly!! 😉

Write back if you need more help.
