Access right of external variable

Description

Write/read access to variables is possible in the basic setting and can be restricted by access protection. If the variable is a variable structure, the access right is inherited to all subordinated structure elements. In addition, for type definition, the access right can be set individually for each structure element (P-EXTV-00019).
