First, there is no configuration required.  The addressing is automatic.

Second, you can't change it.

Inputs address as X, starting at 0, addressed in octal.  So your base unit has X0-X7.

Outputs address as Y, also starting at 0, independent of the inputs.  So your base unit outputs are Y0-Y7.

Your extensions would start at 10, and are also independent.  So no matter which way you connect the 16EX and 16EY cards, they will always be X10-X27, Y10-Y27.

Error 1010 says you have an address error starting at 10 (that's the second part).  The first 10 indicates input or output, and I don't recall which is which, it's in the manuals.

There is no such thing as an FX2N-14.
