Posted 28 Dec 2015 Hi There i have heard from our local mitsubishi dealer, that there is a Fx3U-ENET module which also supports Modbus TCP. so i ordered one, because i am planning to do a Project using a atv71 FU and a Codesys PLC, so the plan is, that these 3 Devices are able to communicate together over Modbus. has anyone done something similar before? what do i need to setup in FX-Configurator EN, and how can i send modbus commands through that module. i am using GX-Works 2 and have a Structured project. any help would be appreciated. thank you jason Share this post Link to post Share on other sites
Posted 28 Dec 2015 There isn't a FX3U-ENET module that support modbus There is one FX3U-ENET-P502 module which support opening P502. You will still need the FB for modbus from the mitsubishi site Share this post Link to post Share on other sites
Posted 28 Dec 2015 Hi Gambit thank you for your fast reply. yes you're right. i have the FX3U-ENET-P502 and on FX configurator i have one Ethernet open TCP, Unpassive, Send, Procedure exists, No confirm, 502 i've now downloaded that FB library, but not from the Mitsubishi site, cause i did not found it. everything seems to be very confusing cause i did not found any manual or help file according to modbus tcp. if i would have a example, it would help very much.. thank you Share this post Link to post Share on other sites
