Siemens S7 data block - String

[Guest Safes]

Hi, I am trying to access stings in Data Blocks with "OPC Scout". However I can access only a few of the DBs. For example I can access DB 20 and DB 28 but not 19. What is the reason? More detail: OPC Scout shows the aviable address from 0 to 31 for accessable DBs, and 0 65656 for not accessable DB. I think it is not logical too. Why may DBs differ from each other? if not why OPC shows different values for different DBs and I can not access some of them? Any help?? Thank you =)
