Hello!
I am using the drivers that are available online for a PID system, SIM960 from Stanford Research Systems. I made the VI attached here and am using the default subVIs "Configure Setpoint" and "Read Measurements" inside two loops. The issue is that whenever the number of the loops is sufficiently large, while the VI would function as intended for maybe >100 iterations, after which Read Measurements would suddenly throw an error: Scan from String(arg1) error 85 and the VI would stop working.
Now I am finding this extremely hard to debug as I have to run the code for quite some time before such an error occurs.
I am using the sub-VIs as intended and while they do work well, it's really puzzling as to what may cause them to suddenly start throwing an error out of nowhere.
