I/O does not exist ERROR message Debug file

Hi,
I was trying to add a handwheel in my work in progress and change the hal file to add the mpg and I can't do it, so I decide to do a restart . And I erase the code in the hal file that I just add for the handwheel. The error says that the output doesn't exist. I create another file using the pnfconf and says the same thing.
I've recently succeed moving a servo and now that happened.

Thanks,

The digital I/O section of the 7I76E was not found

Do you have field power (8V to 32V) on the 7I76E's digital I/O section? (TB1)

Is W8 in the left hand position?

Hello PCW,
Thank you for your reply.
I was trying to config digital input (axis selection and multiplier for mpg), then i got the error. My next step was to deleting code that could cause the error.
I end up to reflash the firmware,board, now it is ok.
