Solution

The VISA Write and viWrite are exactly the same. The reason you see NI I/O Trace differently in development is because LabVIEW and NI VISA are publishing information to NI I/O Trace at the same time while executable file is just NI VISA publishing information to NI I/O Trace. 

You could disable the LabVIEW API in the Tools >> Options >> View Selection to show NI VISA calls only as shown below:
