Posted 15 May 2020 (edited) Hi Thang, In the manual instruction of FX3U-485-BD, this board don't support to connect GOT2000. You should use the ethernet adapter FX3U-ENET-ADP + converter board FX3U-CNV-BD to connect to any GOT HMI.

Posted 18 May 2020 (edited) Be careful, when you change some settings in this page (FX parameter-PLC system2). Take a look to reg. D8120! When you do changes - it only take effect after reset the PLC! I tried with this (look at pic attached) but unfortunately. At last - I took 232-BD and it works now!))), but without!! any settings in FX parameter-PLC system2 ! So, I think you should clear D8120, uncheck CH1 and try. Good luck). And question - is it really FX3U-485-BD ?? Or maybe FX3U-485-ADP?? Edited 18 May 2020 by eziccc Share this post Link to post Share on other sites
