Purpose:The main program calls the subvi to realize the following functions: input a column of array, and divide each element in the array by the maximum value of the array, and display the divided results in real time. firstly,I write a subvi：input a column of array, each element in the array divided by the maximum value of the array, and form a new array. picture1.the subvi panel picture2.the subvi program. then i call this subvi in the main program. picture3. the main program(Add a delay function to observe number changes). thirdly,i run the main program in highlight way. The main program can run normally as well I I can see the number change from 0 to 0.25. picture4. Screenshot when the number is 0.625 but when i run the main program normally, the result number always stay in the last value. picture5.The number is always kept at 0.25!!! Add probes at positions 24 and 25 for testing.During the first normal operation, there is no data at the probe. picture6.Not performed at probe. but Click run again. At the moment of running, the array at the probe is passed in, and 0.25 final data is obtained. picture7.Data at probe.(The number is directly displayed as 0.25！！) So how to achieve my goal and what's wrong with me？thank you!

If you want to divide the input array by the maximum value , then display it element by element every 500ms until all elements are displayed, here's how I would do it. (Note that if you want to delay the output of each element, the wait belongs inside the loop. dataflow principle!) (Make sure that the array is not e.g. negative and the max is exactly zero!) I strongly recommend to go over the learning resources listed on the top of the forum. You currently don't really have the skills to go much further by just throwing things on the diagram and randomly connect things according to some misunderstanding of LabVIEW principles. Words like "real time" have a specific meaning and if you consider the behavior correct under execution highlighting, this has nothing to do with real time at all! Unreal! 😄

Hi DK, there are a lot of images in your message, but no VIs at all! Mind to attach your code? (We cannot debug/edit/run images with LabVIEW!) What's the point of FOR loop set to iterate just once? What's the point of FOR loops set to iterate as many times as the array input contains elements? Ever heard of "autoindexing"? Why are there two uninitialized shift registers??? Is that intended behaviour? That whole "sub VI" can be replaced by this: @DK_Zero wrote: but when i run the main program normally, the result number always stay in the last value. picture5.The number is always kept at 0.25!!! Add probes at positions 24 and 25 for testing.During the first normal operation, there is no data at the probe. When there is an empty array output then the loop will not iterate. And os it will not update the indicator within that loop…

Highlight execution succeeded, but normal execution failed

Solved!

I'm glad to communicate with you. Maybe I should say learning from you.I'll keep your warning in mind.

For a newcomer, I am very grateful for such guidance. Although my English is not good, some words can not clearly explain my intention. Moreover, there is no systematic labview programming idea, and there is no good grasp of various components of LabVIEW. However, I still think LabVIEW can be used as a useful software on my way to become a measurement control engineer.I hope I can enjoy the fun brought by LabVIEW, although there must be a lot of pain.

Finally, I wish you every success in your work 🙂
