Posted 18 May Has anyone done a Mitsubishi FX5U PLC Modbus interfacing with an Omron NX1P2 PLC? Trying to find that since no manuals exist on the Mitsubishi site as well as Omron. Share this post Link to post Share on other sites
Posted 18 May First I put your question into it's own topic rather than on a three year old post to hopefully attract more relevant attentions. Second - I found this Mitsubishi Manual which talks about Modbus - https://www.mitsubishifa.co.th/files/dl/jy997d56101d_FX5(MODBUS%20Communication).pdf Third - I found this Omron Manual which talks about MODBUS - https://assets.omron.eu/downloads/manual/en/v4/w506_nx_nj-series_cpu_unit_built-in_ethernet_ip_port_users_manual_en.pdf Fourth - From what bare little I know of Modbus you'll first need to decide which PLC is master and which is slave. Then you'll map Native I/O of each to modbus registers and the modbus comms will transfer the data. Beyond that it's time for you To RTFM and post your success or failure for others to guide you. Good Luck! 2 people like this Share this post Link to post Share on other sites
Posted 22 May The Mitsubishi US guys did a webcast on Simple PLC with omron but canlt find it anymore. Do have this screenshot file though. It's with an RPLC but the setings would be the same screenshots.pdf Share this post Link to post Share on other sites

Posted 25 May Good info @mike but the FX5 support direct comm to a lot of other brand controller via ethernet.Called simple plc comm So you do not have to use modbus or write any code Share this post Link to post Share on other sites
