Posted 18 Sep 2015 Does anyone know if the FX2N modules such as FX2N-EX can be used with the FX5U? The plugs are compatible - and the colour is the same ;^) - but I suspect that they may have upped the speed of the bus, or made other changes. Thanks.

Posted 19 Sep 2015 Don't know exactly, but this doc hints that the FX5-CNV-BUS must be between. Share this post Link to post Share on other sites
Posted 19 Sep 2015 Thanks, Inntele. Further searching shows that to be FX5 CPU to FX3 bus converter. It looks as though my FX2N modules are two generations back so I'm unlikely to be able to use them with the FX5U. Share this post Link to post Share on other sites
Posted 19 Sep 2015 Transistor, before to give you the advice above, I looked docs carefully. My intuition and the deductive logic say that the FX2N I/O can be used with this bus-converter. I'm pretty confident in it. If you'd like to ask, why they didn't write about it, can answer that they want to sale FX5 I/Os. It's a simple commercial interest + some advertising issues + some manufacturing issues + some technical issues. Share this post Link to post Share on other sites
Posted 20 Sep 2015 I'm certain that if the converter exists a manual for it also exists, and that manual would contain a list of the modules which can be used with it. Share this post Link to post Share on other sites
Posted 21 Sep 2015 The manual has not applicable module list, it refers to FX3 only. My logic is following. The FX5-CNV convert FX5-bus to FX3-bus. The last bus allow to connect FX2N modules directly. So there should not be a problem... Meanwhile, a Ferrary car, equipped with wooden dray-wheels, will look strange.

Posted 20 Dec 2016 Yes it can work. No it's not suggested. I have run a quick bench test and a fx2n-8ey works with no issues. However, a 16ey seems to miss some outputs. I would suggest this is the same for the ex. Sadly I don't have any ex units to try as they are quite outdated now. Hope this helps anyway. Share this post Link to post Share on other sites
Posted 20 Dec 2016 Thanks for the follow-up. We used the correct FX3 modules in the end. Share this post Link to post Share on other sites
Posted 21 Dec 2016 There is official letter from Mitsubishi, but on Russian.Fx5 can work with fx2n special modules with fx5-cnv-bus, and this bus take one address' point. So if you have FX5U + fx5-cnv-bus + fx2n-4ad. Address of Fx2n-4ad will 2. Share this post Link to post Share on other sites
