It all started when my system crashed while saving an FB Graph. When I simulate the program, it enters "System Fault". If I enter Diagnostic Buffer this is what I get: FB not loaded FB number: 907 FC number: 72 Module address: 6204 Requested OB: Programming error OB (OB121) Priority class: 1 Internal error, Incoming event. I've tried "saving as" with reorganization, but the simulator still enters "SF" and Diagnostic Buffer is showing the same error. (although when i first open my project it doesn't appear the error message anymore). What should I do, please?

That DB907 was an Instance Data Block for FB807 (Graph). I've deleted both blocks but my problem isn't solved. The blocks aren't called in OB1, or anywhere else. I think there might be a problem in FC72 G7_STD_3.

Sorry you are right, here is explanation Debugging: Close all STEP7 applications and error message boxes. Using the Explorer, browse the project folder for 00*.LOG files and delete them.Start STEP7 and reopen the project. The error should no longer occur.
