Indicating errors

Error indication
Parameter assignment errors that result in compilation errors (e.g., limit violation) are
indicated in the Parameter view.
Every time a value is input in the Parameter view, a check is made for process-related and
syntax errors and the result is indicated.
Bad values are indicated by:
● Red error symbol in the "Status of configuration" (offline mode) or "Compare result"
(online mode, depending on the selected comparison type) columns
and/or
● Table field with red background
If you click the bad field, a roll-out error message appears with information of the
permissible value range or the required syntax (format)
Compilation error
From the error message of the compiler, you can directly open the Parameter view
(functional navigation) containing the parameter causing the error in situations where the
parameter is not displayed in the configuration dialog.
3.10.5.6

Editing start values in the project

With the Parameter view, you can edit the start values in the project in offline mode and
online mode.
● You make value changes in the "Start value project" column of the parameter table.
● In the "Status of configuration" column of the parameter table, the progress of the
configuration is indicated by the familiar status symbols from the configuration dialog of
the technology object.
Boundary conditions
● If other parameters depend on the parameter whose start value was changed, the start
value of the dependent parameters are also adapted.
● If a parameter of a technology object is not editable, it is also not editable in the
parameter view. The ability to edit a parameter can also depend on the values of other
parameters.
