hello

i have preject step 7, with cpu 315-2dp 315-2ag10-0ab0,

have 6 card 7mh4910-0aa01, mounted on 151-1aa05-0ab0

I did not create this project, I received a copy of the original.

from tests performed I can not read the weight and no data from these cards. I would like to know if I have to install an optional package for these weighing cards
