Hi all
I am using Trnsys 17, and I have tested weather file including the Beam Normal Radiation and Horizontal Diffuse Radiation. 
According to help of type 99 :
Type 99 needs two components of solar radiation (e.g. beam and diffuse horizontal) in order to calculate the radiation on a tilted surface. It can use different combinations:Ib (Beam radiation on horizontal surface) and Id (Diffuse radiation on horizontal surface)I ( Total radiation on a horizontal surface )andId  ( Diffuse radiation on horizontal )I ( Total radiation on a horizontal surface ) and Ibn  ( Beam radiation at normal incidence)
my question:
Is there way or type I can use to input the weather file as it is " Normal rad.& Horizontal Diff.? 
Thanks

Best Regards
