This dialog box informs you that the reference data are out-of-date.
The reference data are generated by the language editors directly during compilation. As generating reference data is optional, it is possible that the data are not complete or are out-of-date when you select a view.

Examples

· If a block is deleted, the reference data for this block are retained although they are no longer valid.

· If a block is generated again in the SIMATIC Manager, there are not yet any reference data for this block.

· If a block is modified using editor and the option "Generate reference data" was not activated in the "Customize" dialog box of the LAD/FBD/STL Editor, the reference data for this block are out-of-date.

You can select one of the following options for the reference data:

· Update the blocks, or

· Regenerate blocks.

Select the option "Update the reference data" if you want to generate data for modified or new blocks. The data for deleted blocks are then no longer displayed.

Select the option "Generate the reference data again" if you want to delete any existing reference data and generate the reference data completely again.

Note:
If no data are available, only the option "Generate the reference data again" can be selected.
