Parameter access level and security

The parameter access level determines whether the user has access to
Menu 0 only or to all the advanced menus (Menus 1 to 22) in addition to
Menu 0.
The User Security determines whether the access to the user is read
only or read write.
Both the User Security and Parameter Access Level can operate
independently of each other as shown in table Table 5-5.
