__VARINFO from string name

[aFouraker]

I have an older application in which I used SysLibGetSymbolAddress to get the pointer to a variable. That was in the SysSymbols23 library that is only support with 32 bit applications. Ideally, I could get all of the info about a variable from its name passed as a string. Is there a library solution for this?

Any thoughts on this one?

• The library SysSymbols23 seems not part of the ctrlX PLC engineering anymore
• I wonder on your headline __VARINFO which is similar but different
  • __VARINFO is a compiler command which provides many information based on a PLC variable name
  • SysLibGetSymbolAddress provided the the variable address based on a symbol name

What do you want to do? Maybe there is a different solution like:

• __VARINFO
• datatype ANY
• or anything else

otherwise CoDeSys must say if therer is a replacement for the library.

Thanks @HmiGuide, I was able to get some sample code from CoDeSys and a sample project is attached.  This is an archive that has been zipped up.

Thanks for the example. It is helpful for me, too.
