Validation and Documentation of the Safety-Related Project

General Information

After commissioning and completing the safety-related project, an acceptance procedure must be performed. Once this procedure is passed, any additional project modifications lead to further project reviews and re-validations. To help avoid this, Machine Expert - Safety provides the possibility to certify the validated project. A certified project is protected by password against particular modifications and has to be unlocked before re-editing.

Validating the Safety-Related Project

The following procedure is only possible if the safety-related project has been compiled successfully.

Defining a project as validated:

Step	Action
1	Select Project > Project Certification... Result: The Project Certification dialog opens.
2	Define a certification password by entering it twice into both input fields and confirm the dialog. Result: The project is now certified and locked. Only particular operations are possible. The validation (certification) is displayed in the status bar.

Step

Action

Select Project > Project Certification...

Result: The Project Certification dialog opens.

Define a certification password by entering it twice into both input fields and confirm the dialog.

Result: The project is now certified and locked. Only particular operations are possible. The validation (certification) is displayed in the status bar.

Refer to the chapter Project Certification in the EcoStruxure Machine Expert - Safety - User Guide for further information on the operations which are possible while a project is locked.

Removing the validation and re-editing:

POU Verification Flag

For marking validated POUs, Machine Expert - Safety provides a POU verification flag. After verifying the code of a POU, the verification flag can be set for this particular POU by selecting the Set verification item from the context menu of the POU icon.

Refer to the chapter POU Verification in the EcoStruxure Machine Expert - Safety - User Guide for more information.

Project Documentation

Machine Expert - Safety helps you to document the safety-related project. For that purpose, the dialog Project Info is provided which you open via the Project > Project Information menu command.

Dialog fields with a colored header must be filled out each time a new project version is developed. Fields with a gray header are optional. However, you should enter data in the fields, even if they are optional.

The Project area in the Project dialog tab is read-only as these data are polled by Machine Expert - Safety. Some of these data can be copied to the Clipboard.

The Project dialog tab displays various checksums for certain parameters or data which have been calculated by Machine Expert - Safety. You can use these checksums to find out if projects differ in their parameters or data. By comparing the checksums that are calculated separately for the various parameter and data groups, you can see which parts of the projects are different.

The data in the Checks dialog tab are part of the acceptance test procedure.

Refer to the chapter ‘Project Info’ Dialog in the EcoStruxure Machine Expert - Safety - User Guide for more information and detailed description of the various CRCs.

Printing the Project Documentation

After the successful commissioning of the safety-related application and editing the project documentation, it is mandatory to print the whole project. The File menu in Machine Expert - Safety provides commands to define printer settings, display a preview and to print the entire project or parts of it.

Refer to the chapter Printing and Preview in the EcoStruxure Machine Expert - Safety - User Guide for more information and detailed description of the various CRCs.
