Answer

This error occurs when the system configuration set by the loader software differs from the actual configuration.
For example, a defined module is not mounted on the base board, or the module type registered by the loader software differs from the actually mounted one.
To solve this error, specify an error part by using the configuration check function and correct the mismatch part.

[How to use configuration check function]
   For Expert (D300win):
   In the [Online] menu, select 'Project Control,' and then click the [Failure diagnosis] button.
   On the 'Failure diagnosis' dialog box, click [Check Configuration] button.

   For Standard V3:
   In the [Online] menu, select 'PLC Operation (Run/Stop, Load),' and then click the [Failure diagnosis] button.
   On the 'Failure diagnosis' dialog box, click [Check Configuration] button.
   By using the above configuration check function, you can detect mismatches between the system configuration set by the
   loader software and the actual configuration.
