I'm not familiar with these programs, so I can't give you specific
advice about this.

Although git is not very picky about the contents, it is optimized to
track text files. Things like showing diffs and merging files only works
on text files.

Git can track binary files, but there are some disadvantages:

- Diff / merge doesn't work well
- Compression is often difficult, so the repository size may grow
  depending on the size of the things stored

These disadvantages are not limited to only git, other SCM systems also
have to deal with these problems.

So if the Ladder logic is represented as text source, there is no
problem with it. If it'sbinary, there might be other sollutions better
suited.
