Ok VinTan. looks that people in CODESYS forum are a bit slow in providing the info you want or it is not the proper thread.
I sujest to write direct to 3S the company that invent CODESYS.
At the end you will find what you are looking for. I understand what is that, but I can not help you on that.
Keep looking on that because CODESYS is a must for automation engineers.
Do not forget if the PLC supports IEC 61131-3 is a success. And CODESYS is a stable platform with a huge installed base.
Do what other manufactures did. Be a CODESYS member as a manufacturer. Then you can support and sell your product trough other channels. You will find recognition.
Now another soluton you have to examine on top of the CODESYS solution is open source program Beremiz (http://www.beremiz.org/
When I fist started this thread my idea was to use Beremiz with Raspberry. So you could have both hardware and software open source.
I ever use 3 years ago a commercial PLC with Beremiz (Smarteh's MC8)
I still have Smarteh's MC8 in my desk. That was a working comercia PLCBeremiz. Stll is The company has developed it more.
I even had a privet chat with the a great guy Edouard TISSERANT who started Beremiz. High knowledged engineer and whiling to help me.
But that time Beremiz was not fully ready on Smarteh's MC8 and i needed solution fast for the company I am working so I choose CODESYS instead with ABB.
If you look back into this thread there are people that started beremiz with raspberry but then do not know what happened.
Anyway as far as I see koreans started a ne vertion 2 years ago and project is still allive if you see here: http://sourceforge.net/p/beremiz/mailman/beremiz-devel/
Have a look. Beremiz is not a joke ! It is a serius project
Beremiz looks abandonded but it is not
look discutions at: http://sourceforge.net/p/beremiz/mailma ... nth=201511
So I suggest go for Beremiz as well for CODESYS. Whichever comes first. Both environments support all IEC 61131-3 languages
Raspberry is a little miracle and deserves more effort to bring your interfaces into 61131-3 support .
I already use a CODESYS automation in my home. Even my dishwasher is using CODESYS!
So keep trying...
Still what is the suggested price for I/Os?
