The robots are the same model. We lost NCP01 and had to swap to a new board and it does look like the software versions are different. The version in the robot the cmos is taken from is NS3.11.00A(US)-27 and the controller we are trying to load onto has version NS4.64.00A(US)-00.
Talked to Yaskawa and they are sending me the NS3.11.00A(US)-27 version to load.
