Sorry, I have no idea what a "parallel" or "serial" shift register is.  Could you elaborate on what it is you are trying to do?

Thanks!  🙂

Are you talking about extending the length or "history" of the shift register? You can drag the node down to expose a shift register buffer for more than one element.

thank your reply! what my meaning is just like I have an array of input of the shift register 1，2，3，4，5，6，7；In the calculation process, I would like to achieve in a row ：after 1 finish  the calculation ,2 begins,later 3,4,5,6,7，this is Serial;but in labview is Direct the entire array operation，this is  

Parallel，can you help ?thanks!

Are you using the shift register in while loop? Try using it in for loop, I believe you are looking for "Auto indexing" operation.

If I didn't understand your problem correctly, please attach the code you have developed.

I want to achieve ：Each element of the array in the shift register Compare with 5，If less than 5, the output is 1, otherwise 0；but as you can see the vi is wrong ;Error reason is because of the shift register only for computing the entire array but not Single element，any suggestion?

better to use for loop with auto indexing enabled ( by default ) for input array.

you will get array values one by one.

then compare it with desired value and you can use bollean to 0,1 to get the out array of 0 and 1s.
