Hello! I have the same problem in TIA Portal V16, the block is closed and the right click menu don't show the "know-how protection" option, and in the block properties the protection section is disabled. When I try to open de block, the password dialog never appears. ------------------------------------------------------------------------------------------ |

Hi there, I just want to add one further thought to this: With all that being said by alizon, do NOT just come to the conclusion that it is a nice idea to put your code within these Pre- and Post OBs! Make sure you really, really have understood the OBs, their operational sequence, how overflows are handled, and what this means: https://support.industry.siemens.com/cs/de/en/view/109781848/132235432587 Otherwise you'll probably run into issues, very likely because of overflows of the OBs, then have to either change the whole timing or your program structure, and both has further consequences in most cases. So yes, there are things that really need to be called in those OBs, there is stuff that is nice to be called there, but there are also many, many other things that do not need to be called in there, or should be solved in another way. (All that being said by someone who had to deal with such issues way too often ) Regards, |
