Issue Details

I am using multiple register item readings of a unique register in many loops inside FPGA VI. Do the readings block each other?
 

Solution

No, multiple readings of a unique Register Item do not block each other.
Register Items in FPGA are not working as a Shared Resource.
 

Additional Information

Although the Register Items Reading is not a Shared Resource, a race condition can occur running multiple Writings of the same Register Item in parallel.
