value assignment inadmissible

[lin-ycv]

Used the "UseController" option for my tool, but when it tries to read the load data it throws an error
If I remove that line everything still works fine, but I'd like to know why it's throwing the error

Find LOAD_DATA[5] in the file R1/System/$config.dat of the controller. Is it assigned to a valid value?
