  1. Hello everybody. I am looking for a solution for an FX3U with mounted FX3U-ENET on the right, to communicate with an FX3GE. I need to read and write some device in the FX3GE from the FX3U. I have made a paired connection in the FX3U-ENET module and made an MC connection in the FX3G. But how can I send or read data? Is there another solution apart from the MC-Protocoll? I am using GXW2 version 1.551z. Languages: ST or FBD Thank you in advance Dave
  2. Indirect addressing FX3U

    Hi, I have a FX3U-16MR/DS with 485ADP-MB + 232-BD. The 232-BD is linked to a radio modem and the 485 to frequency drive. There is also an additional IO card attached. This is my first project with mitsubishi and with modbus RTU. I'm supposed to add a couple of data to be sent over the radio modem attached to 232-BD connection but I can't figure out what it is already sending. I think the write data is to a registed D2000 which is an array and then sen't over the radio modem. But I can't for the life of me figure out where in the program something is written to the register so I could find out how much free space there is in the Array and I wouldn't be over writing something. So I'm just guessing here and indirect addressing is used but I don't understand how it is done in mitsubishi? The program has been written with IEC developper and I'm only familiar with GX works2. Any examples or help would be much appreciated. Thanks
  3. Has anyone discovered a laptop that will connect to all mitsi PLC types (and Melfa Robots) via MELSOFT TCP connection. My Dell 5510 seems to have the most random dislike for this kit. at the moment it is happy to link to Q series but wont touch FX at the moment (this has not always been the case). I have checked all basics I know; 1. Pinging 2. Port setting to Melsoft 3.  Direct connection to FX3U-ENET avoiding the unmanaged switch (altering settings to suit). 4. Using FX Configurator to try and diagnose,checking the module settings in the project. 5. Disabling laptop wifi connections 6. Disabling firewall and AV. 7. Trying to setup a UDP connection (this seemed to work on Q series) Pffff..... Any thoughts?....I am obliged to use a site networked laptop so there maybe IT issues....however due to my ongoing frustration I will order a laptop and use offline like a wild man
  4. FX3U-485ADP-MB

    Hi! I have some concern dealing with the FX3U-485ADP-MB device which will be plan to install and a total of 17 modbus devices(Chinese brand converter 4-20mA to RS485) where going to communicate. I'm new to this feature of FX3U family and I'm using GxWorks2. Is there anyone that can guide me through this device/development? Is there a program block for this like the one I have been use for analog modules(FX3U-4AD)? Looking forward to your help!   Thanks a lot! Marky

  8. Unable to Monitor in GXworks2

    Hi! Anyone can help regarding this issue. I'm not able to monitor the Motor Block that I have created. there's no error either in the output screen but i'm thinking what is the cause of not running in the simulation which shows the Motor Folder RED  even it was compiled. thanks for the help!     Note: I'm new in mitsubishi.
  9. FX3U Analog Programming

    Hi,  Anyone can help how to program a analog coming from a level transmitter? I have 8 analog inputs (2 unit of FX3U-4AD) to be read out into the plc program. how can this be possible.

  10. Temperature controling with module

    Hello to everybody! This time I need to make a program to control temperature ... Some help? I don't know how to use an analog module, I'm just starting to working with them. The PLC I have a FX3u-32MR/ES (Mitsubishi), and I have the modules; FX3u-4AD-ADP and FX3u-4AD-PT-ADP for temperature measurement. PLEASE HELP? Have a good day!

    Hello everybody. My FX3u PLC doesn't turn ON, I connect to 24Vdc and nothing, not even the POWER led :( Any recommendation??????????? PLEASE   
  12. Hello PLC guys. I need some advice for developing project. We have aim to rework mobile crushing complex. There are have 8 VFDs ABB acs 800 with CANopen Adapter Module RCAN-01. We plan to use mitsubishi fx3u plc. I haven't work before with CanOpen protocol. Is it passable to programming communication between Fx3u-can and ABB drives or easier way to buy modbus or profibus communication options for inverters? Before create topic, i have read RCAN-01 (3AFE64504231), fx3u-can (JY997D43301) manuals and sheet about canopen protocol. I have also downloaded:  1)Fx3u-can eds from mitsubishi. 2)RCAN eds from abb. 3)FX3CANopen_GW2_V120 libreary. But i didn't understand how using eds files for configurating network. As i know mitsubishi haven't special software for it like profibus dp configurator for gsd. PDO it is like PPO for profibus? I need just send to inverter CTW,Setpoint Ref and recieve from inverter STW,Feedback Ref, Current and alarm word. For modbus and profibus it is easy configurating via inverter's parameters. What types of PDO better use for this task and how it prepare? Need i use NMT,SDO,Hearbeat? Can someone give me example projects with canopen communication with any vfd in gid/gw2 or step by step explain what need to do?

  16. FX3U-ENET and Modbus

    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
  17. Modbus client problems with FX3U

    Hello, I have the following problem, I have two PLCs FX3U-16M, with a communication module FX3U-ENET-Port502 in both PLCs have built a server under Modbus TCP and a client to read the registers of the other PLC, my code of Modbus TCP client presents the error code C017 and errors in the channels for reading and writing the registers. Of course grateful for his help.
  18. FX3U-232-BD

    Hello, everyone. I have FX3U-32M PLC with expansion board FX3U-232-BD. I successfully can read and write program through programming port (RS-422 mini-din 8pin) at GX Works2. Now I am trying to connect through FX3U-232-BD, but I can’t. I have a task controlling PLC with OPC server. And I must to connect through FX3U-232-BD, because to the programming port connected touch panel. What should I do, to do it correct. At the program I see, that H81 is writing to the D8120 register. Which means that channel 1 settings is: 9600 speed, 8 bit, no parity, 1 stop bit. But I can’t connect with this settings. Cable which I use: PC PLC 1 1 2 3 3 2 4 6 5 5 6 4 7 NC 8 NC 9 NC I am new in this type of PLC, and I need fast solution. So you are my last hope. Sorry for my English.
  19. Non-volatile memory GX Works2

    Hi all, Im trying to figure out how to create non-volatile memory tags in GX Works 2 (using a FX3U controller), so that the values stored in the D registers won't keep zeroing out every time the controller powers down. Does anyone have any helpful tips on how this is done? Thanks

  22. Good Day, I would like to know how FX3U-64DP-M will keep cyclic data exchange running even if one of its active slaves is disconnected or shut off. Thanks.
  23. Hi everyone! I have this simple problem, but cant get over it. I have structured ladder/FBD Project and i use GX works2. As topic tells I use analog signal from field. Now, i need to compare this value X (from field) to Values X1 and X2, meaning if value X is between values X1 and X2 then M1 is true. Ok, but what function i need to use for this? Best regards, Juha.

    Hi all, Im new with plc programming and now I need some help. As topic says, I have FX3U plc and gx works2. Now, I need to tell stack heigth as positions by output. We all agree, that you can tell ten different situations when you have four outputs (Y1 and Y4 = position five). Is there any practical/ reasonable way to do this when you need use outputs. For example, is there any Functions for this, or? Best regards Ultra.
  25. PLC->OPC->Labview

    Hi, I have been trying to communicate between a PLC(Mitsubishi FX3U) and Labview (using Data Socket) through a KEWserverEX OPC-server (using a RS232C COM Port cable). I have been successful at that by using baud rates ranging from 9.6kbits/s to 115.2kbits/s, with average reading time into Labview ranging from ~40ms to ~10ms (of course depending on baud rate) per value. However, this is too slow for our purposes, and we need it to be in the area of 1-3 ms per value. Are there any tricks to decrease the reading time between the PLC and Labview, or do we perhaps need an ethernet module? Kind regards Bjørnar
