Hello all, I write some values from my standard program into a safety DB, more special into an array of Integers in a safety DB. The next I do is to compare the values in these arrays in the safety program and switch on an off some safety-critical OSSD in dependence of these values. I already wrote with the Technical Support who said, that the safety program should trigger if the manipulated element of the array would be used in the safety program, but that dosn't happen. How can I check in the safety program if my F-array was manipulated? (It's necessary in the safety program, because when someone would manipulate the safety programm there would be another checksum, than I generated) Is there maybe any checkbox I have to activate? Or other question: Is it possible to compare the actual value with the start value or only use the start value? - CPU 6ES7 518-4FP00-0AB0 V2.5 - TIA Portal Version 15.1 the possibility to use F-Arrays read-only in the safety program with TIA V15: Original Text of the Technical Support: die Möglichkeit F-Arrays im Sicherheitsprogramm lesend zu verwenden mit TIA V15: Beim Anlauf des Sicherheitsprogramms werden im Gegensatz zum Es gibt keine Möglichkeit im F-Programm auf das F-Array zu schreiben. |
