The profile UDF looks fine. if there is any compilation issue, please check for errors.
if there is no compilation issue Please see below:
1. since your velocity profile is dependent on time, if you plot at the beginning it will give Uinlet=30. but as the time gets updated, you will see a nice sine profile curve at your velocity inlet.
