  2. Hi all, How do i change the channel to acquire from while running. i have 60 buttons laid out each has channel numbers associated with it in another vi not attached here but for simplicity below is wat i have done the numeric to string will be the channel name+number, since the selectionprocedure happens from a numeric control on FP in my requirement. final goal is i need to be able to select a channel and view its graph on FP without stopping the program. problem is i have 60 channels to read from and thought to make each case foreach channel with corresponding name, but is there a better way to doit. any help is much appreaciated, Thanks in advance select channels programmatically LV8.2_modvi(2).vi
  3. Hi ppl, need help I have an application which involves a lot of subvis and all need to be opened once set them to run, minimize or just disappear and give back control to main vi. problems are: 1) since there are many subvis and all needed to be running , the laptop screen fills up and so , if minimized to taskbar it still is a problem to navigate with lots of subvis running, so, can the subvis be made like this-- pop-up when i click button on the main vi and then run/stop my sub vi manually and press button on subvi to disappear while it is still running in the background, If i wish to see it again It should be able to pop it up again when i press the same ok button on main vi. Please see attached, just simple vis, the number on the main vi front panel should be still running after once i start the subvi and make it disappear. I tried with the suspend when called on subvi node setup, when i try to close the window, control is returned to main vi but it stops running and then exits. tried with vi reference, fp.close, fp.state hidden but i cannot get it work as wished This same ok button should be able to bring back the subvi from hidden ,so basically it acts in 2 ways, 1st time for popping up subvi and later just unhide, so that i can view and hide the running subvi whenever i want anyway around this thanks

  6. Thanks for the reply, i will need more time to learn jki state machine, but for now its kind of urgent so, im attaching my vi , please help!! I am using 2 elapsed time vis ideas: 1) I can use a case structure but the 8hrs timer gives out a boolean only when elapsed and instantly changes to false, if some how i can make that boolean to be true for 30 secs and do my operation and change back to false while the 8hrs timer resets at its time 2) I can use the get start time of hrs timer and add 30 sec to it and give it to 30 sec timer's "set start time " and do my operation within that 30 secs and wait for 8hrs again but, i am unable to do any of these may be because both are in the same while loop or something, even if put a while loop around the 30 sec timer and stop the loop when time up, its not working, it still resets, i need something that can start a while loop (programatically) not when we press the run button, 3) if we make the 30 sec timer a subvi and put in a case structure and contol its running/run button... 4) if you can give me in a standard state machine i guess i can understand, but im thinking if the 8hrs elapsed it will wait for the 30 sec thing to happen and then start 8hrs again, but i need to run that 8 hrs,8hrs,8hrs silently in the background and do 30 sec thing simultaneously, not wait for 30 secs any help would be much appreciated??? thanks

  8. Hello ppl, need some help!! please see attached if this is not clear ( 0)----8hrs--------(8)-------8hrs-------(16)--------8hrs------(24)--------upto 14 days 30secs-----------30secs---------------30sec----------------30sec-----------of data @ each 8hr interval every 8hrs i need to able to write up 30secs of data to spreadsheet and continue the operation until the end of expt (14 days), also optionally i should be able to write some 45 sec of data between the 8hrs gap without interrupting the original interval setup I was trying with 2 elapsed time vis, one countsdown 8hrs ,when elapses it should trigger another 30 sec timer which will enable those 30s of of writing and stop.again when 8hrs elapses it should write 30 seconds.( it should not stop, it should reset again and wait for the 8hr timer to set it) but i am very much stuck with these timers, another types or ideas welcome any help would be much appreciated thanks, free mason
