Different Values in Shift Register subVI call

[Luis_R.]

Hello,

I have a subVI to add a trim condition in a system, I am using shift registers to save the final value, I am using this VI 3 times in the program, but the problem is that the value saved in the shift register it's the same in the 3 locations, I was wondering if there is a way to call a subVI multiple times indicating different values in the shift registers.

Thanks.

If I understand your questions correctly, you need to make your VI reentrant and that will give each clone it's own data space. You can do this by navigating to File»VI Properties and select Execution from the Category pull-down menu. If you have any questions, post back.

Hello,

That solved the problem, but just another question, I didn't get the meaning of the options under reentrant execution, Share clones between instances and Preallocate clone for each instance, I leave it in preallocate clone and it is working fine. Does that has to do with memory??

Thanks.

Yes, leave it to the default specified. I would suggest going into Help from that window to understand what's going on; they have provided an excellent explaination. If you have questions, post back.
