Configure Siemens TIA Portal Checksum comparison jobs

By using the upload variant Checksum compare only, the individual checksums of the blocks are compared. Changes to the code of the blocks are recognized and the block is displayed as "changed". A detailed view of the changes is not possible.

Info

No backup is generated. This means that you cannot perform a detailed comparison or restore. The actual values cannot be saved or compared.

All controllers from the project are always compared.

Procedure

  1. Create a job with the TIA Portal upload type.

  2. Under TIA Portal settings, select the Checksum compare only upload variant.
