Checksum comparison

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. Start the AdminClient and open the Jobs module.
  2. Select your TIA Portal component in the Project tree.
  3. Click on the Create button in the ribbon or drag and drop the component into the Jobs area.
  4. Check whether the upload type TIA Portal is displayed in the Job configuration area.
  5. Configure the General, Notification, Upload and compare and Create a version automatically after job run sections. The Notification and Create a version automatically after job run sections are only displayed if the required settings have been made. If you are working with Agents and the versiondog server and the TIA Portal software are not installed on the same computer, they must be configured using the communication parameters of the project. The agents must be installed in advance.

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

Info

If the project contains a CPU password, an error message is displayed, since no CPU password can be transferred in the checksum comparison job.
