Yer, it's pretty good. A codesys runtime can be brought for £50 but but it's easily prograable in any IEC language.

You can even get commercial products based on it too. Which then look more like PLC and have relay modules 24V etc so can slot right in as a cheap PLC. And you still have a pi at the heart to do anything else you want.

Such as:
Piextend
Revolution pi
Unipi
Controllino
