3.7.3.2.1
Setting authorization for parameter change
If device parameters need to be changed, the user must activate the access mode (“log
in”). Changes become active when the access mode is set back to “Run” (“log out”).
Log in and log out must be done separately for each parameter. It is not possible to
change several parameters with a single login.
Executing a special command is required for permanent saving of the changed parame‐
ters before logging out,
see "Special functions", page 24
.
Previously activated continuous data is interrupted by the “Activate access mode” func‐
tion. Continuous data output is restarted with the “Deactivate access mode” function.
