Posted 8 Feb 2016 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. Share this post Link to post Share on other sites
