> DCB_Access:LPDCB := DCB'Access;

  This says you want the variable DCB_Access to point to DCB, which is
a *type*.  You probably meant it to point to an *object* of type DCB,
in particular, the object DCB_1, so you need to say:
  DCB_Access:LPDCB := DCB_1'Access;
Also, in order to have anything point at DCB_1, you are required to
announce in public that there may be ways to modify object DBC_1
other than via the name "DCB_1", ie, DCB_1 may have aliases.  Say
  DCB_1: aliased DCB;
and then the compiler will let you make pointers to DCB_1.
