100% agree with this. IMO there are a few efforts to modernize PLC programming but I feel like they are still stuck in the 1990s software development. Take a look at Codesys, got Git support few years ago and in very bad shape. How do you test your code, in the field or buy another Codesys testing plugin....which is in rough shape.

The issue is as machines get way more complex this issue gets worse. Also there are generations of PLC devs that still want to stick with ladder logic. Huge fragmentation.

Ladder is a fine choice for visually animating Boolean logic

The fact is the unmodernized plc platforms deliver working machines and plants. The projects are built, commissioned, and unlike modern software they are finished and left to operate instead of constantly modified With no benefit to the end user

... sort of. Past a certain level of complexity you get into trouble with just PLC programmers alone.

Don't get me wrong. <PLC programmers> tend to also have electrical skills and some are pretty good at their jobs, and you can learn a lot from them!

But ... they're not programmer programmers. It's a different skill-set with only so much overlap.

Then why is nobody using assembler for modern software projects?
