Hello,

did you try use CPU 226? Can you on other side going Online with your CPU now?

Update: ok, try Online connection to your CPU via CPU type. If detection will be successed, you can have your CPU recognized by MicroWin probably. Then you click on it and select for next work.

I tried but its not work

Hello,

sry, what's not work? Select CPU226 or go Online and select right CPU? You can try go Online with your CPU and MicroWin can recognize right CPU type, then you can start work with it as new prj.

Update: what connection type you're using? Adapter, interface on PC?
