Qualification and Verification

After you download the application project that contains the imported safety Add-On Instruction, you must compare the instruction signature value, the date and time stamp, and the safety instruction signature values with the original values you recorded before you exported the safety Add-On Instruction. If they match, the safety Add-On Instruction is valid and you can continue with the validation of your application.

Next, test the application program. This step consists of any combination of Run and Program mode, online or offline program edits, upload and download, and informal testing that is required to get an application to run properly.

To validate the project, perform an engineering test of the application, including the safety system. For more information about requirements, see Validate the Project.

An independent, third-party review of the safety system can be required before the system is approved for operation. An independent, third-party validation may be required for functional safety certification. For more information about safety assessments, see the Machinery SafeBook 5 Reference Manual, publication SAFEBK-RM002

or Process SafeBook 1 Reference Manual, publication SAFEBK-RM003
