CRC checksum for Program validation

[MST]

Hello ctrlX team,

I'm trying to compare the actual CRC checksum of my safety program with the sum shown in my validation report.

Yet, I somehow cant find it in my offline program nor online on the controller.

According to the documentation i would assume to find it underneah the Configuration checksum in the Diagnose -> "Systeminfo" as shown in the picture attached.

Thanks for your support 🙂

Hello MST,

besides inside the validation report, you can see the CRC first in the Compilation report directly after compilation (either explicitly or implicitly when connecting and uploading to the SAFEX-C):

The Message Window - Compilation is stored in a file <configuration>.log in the directory where the configuration (*.spl2) is placed. It is another place where the offline CRC can be checked.

You then want to compare it with the CRC inside the controller SAFEX-C.1x.

As soon as you are connected to the SAFEX-C in the "Device" mode, you can switch the connection into state "Diagnosis". You get there another window called "Diagnostics" with various tabs. The tab "System Info" shows the Device Config CRC amongst other central information.

Please mark this as "solution" if it helped to fix your problem!

Hello MST,

now I understand. You see a mismatch between documentation and ctrlX SAFETY Engineering or the behaviour of the SAFEX-C.1x.

You refer to the Program CRC. This is a remainder of earlier versions. It does not exist anymore. It will be removed from future documentations. There is only one CRC, the device config CRC!
