F-Blocks collective signature detection

Hello,

Is there a way to know , track or be notified every time the F-blocks Collective signature (Safety checksum) has changed?

I haven't found any information that i could use. I would really apreciate any help.

Thanks a lot.

Hi ,

you have the possibility to read out the collective signature .

Here at page 128 you can find more about it. Once you've read out one.
you can program two fields which must be constantly the same , if not you can program an alarm (which will be logged) which will tell you time, date and both signatures.

By hand you can check the logbook (and even print it out)

This will be the value you need : "F_GLOBDB".F_PROG_SIG (display format is HEX)
