Posted 8 Nov 2010 Hello, I am currently doing a project where I needed to add output expansion. I have never used these units before. I have a FX2N-16EYT. I cant seem to find any manuals to set up the module. I am using a FX3U PLC. Is there any setup code for this unit? Can someone point me in the right direction to a manual? Thanks in advance, plcdp Share this post Link to post Share on other sites
Posted 8 Nov 2010 You don't need any code, the addresses starts at the first octal after the BaseUnit address. E.g. FX3U-16 has Outputs Y0-7, then the extension starts at Y10. Share this post Link to post Share on other sites
Posted 8 Nov 2010 (edited) There's no configuration needed. You just need to address your output starting at the next octal block from the main cpu. If the last output on the main was Y27, your first new output would be Y30. You do need a converter to go from FX3U to FX2N extensions (p/n FX2n-CNV-IF??? not sure). All manuals can be found at www.meau.com Edited 8 Nov 2010 by bobtalbot Share this post Link to post Share on other sites
Posted 8 Nov 2010 Hello, Are you sure a converter is necessary? I currently use FX2n extensions with FX3U CPU's with no converter. i.e. Analog in/out, CC-link etc... Thanks for the input, plcdp Share this post Link to post Share on other sites
Posted 8 Nov 2010 (edited) Sorry for the late answer. No, you don't need anything for a FX3U. I think botalbot is thinking of FX3UC (Mark the "C" for compact), which needs an IF converter to be able to connect extension modules (both the FX2NC and FX3UC needs this converter).
