Parameterization
User parameters
Lock and key
8-4
In principle, parameters are firmly assigned to the menus. However, the
"User parameters" menu has a special status. Parameters assigned to
this menu are not fixed, but can be changed. You are thus able to put
together the parameters required for your application in this menu and
structure them according to your needs. The user parameters can be
selected via P360 (Select UserParam).
In order to prevent undesired parameterization of the units and to
protect your know-how stored in the parameterization, it is possible to
restrict access to the parameters by defining your own passwords with
the parameters:
♦ P358 key and
♦ P359 lock.
