I got this error and my PLC stopped. I found another thread here with the same error, but it is related to C++. I don't use C++ but C#.

 

What does that error mean?

 

23.09.20 11:06:45.223 Arp.System.Commons.Runtime.SignalHandler                     FATAL - Signal SIGSEGV occured.

Stacktrace:   at: /lib/libc.so.6(+0x28980) [0xb6a0e980]

 

Thanks

    Hi Alex,

    This is a segmentation fault signalled from the operating system, indicating that an application tried to access memory that it shouldn't have, probably because of a programming error.

    There is some information about this type of error on the internet, including this discussion on Stack Overflow:

    https://stackoverflow.com/questions/1564372/what-causes-a-sigsegv

    In your case this may be related to the issue that Tyler is helping you with. If you are able to give Tyler a minimum working example that demonstrates the error (not necessarily your complete FB), then we can reproduce the error here and advise on a solution.

    Regards,

    Martin.
