Whats the problem?

when you have this error, may be you have to check the configuration of you I/O device in Control Buider.
The configuration in the project need to be the same as the hardware where you download the program, during Codesys session.
If not, you can have the descripted error.
If you give as more information, we can help you better
Yes this is because you have done some wrong configuration and actual IO module is different as you configured..
So what you can do for the time being as you can Ignore all the modules and download the PLC program and restart the PLC again.
Check attached snap shot.
Selet Ignore module as yes.
