PLC on STM32 idea

Some companies have PLC softwares (like as

IEC 61131-3 Development System CoDeSys

)

that have a runtime core that can be programmed on STM32 micros and we can write PLC programs and download it to stm32 without any C code. If ST sell stm32 with PLC capability inside it ,then we can buy it(PLC runtime  license fee will be added to stm32 price ) and use in our projects. Doing this job for small companies and individuals is impossible. What is your idea?

Why wouldn't you just buy the aforementioned COTS implementation instead of faffing around with a chip level solution? ie If you as a business cannot field a competitive solution, from a licensing/whatever perspective, use the solution that is competitive/available. Presumably all the added value is the unique software you develop under this environment.

''Doing this job for small companies and individuals is impossible.''

Doing what  job, exactly? There are many small companies and individulas that manage to successfully program microcontrollers - including STM32...

It seems from Wikipedia that the CoDeSys is license free ??

I have seen/hear fo umpteen ''we can make a PLC much cheaper'' projects.

They have all fallen by the wayside since when the ''industrial strength'' damage resisting I/O was added (after realizing the necessity) the cost far passed the cost of a ''store bouight'' PLC. Erik
