Problem with data x y displaying and encoding

[202228013@inu.ac.kr]

We have a LabVIEW programing for motor controlling designed based on 32bit dll. and 32bit Labview software from a long time ago. However, we want to adapt this programing to a 64bit dll. to run in 64bit Labview. We tried to recompile it, but there is 1 problem in the X Y displaying (figure), no matter how much the motor move. the position remained the same (=0) and encoding part turned crazy. We have checked and compared 2 source code (32 bit and 64 bit) for dll. libraries, nothing is different, and parameters in labview setting in the Call Function Node of the related VIs also are same. What are other reasons we need to consider and how to solve them?

Thank you!

You can attach LabVIEW to the debugger and debug the DLL. See Debug DLL with Labview and Visual studio

Thank you for your suggestion, we have checked it but still couldn't find the reasons for now. So, currently, we are using the 32 bit version (32 bit dll) instead and it is working fine.
