The IDE for these PLCs actually has VCS integration! It's SVN, but it's still better than nothing.

Its on-disk representation of graphical 61131-3 languages (FBD / SFC) is text-based and somewhat human readable, so there's nothing technically preventing the developers from keeping all of this in any other VCS of their choice.

There is nothing wrong with SVN, it's just that Git allows for some workflows that are better suited to larger teams and more complex projects. But for your average PLC project with a team of 10 and one binary as the output it should be more than enough.

You likely won't see any 'feature branches' or frequent merges in this kind of environment.

Except merging things, and handling a lot of files...

There are lots of small things wrong with SVN. But it's indeed usable.

I'm aware of repos with a few million files in it that have been going since 2003 and not a single issue.

Merging things is different than in Git but it works. I use both, and I'm not religious about either, some things are easier in Git, some are easier in SVN. Git provides more footguns. And loads and points them too.
