  1. 1 slave to multiple masters

    Hello everyone. I got the project where plc Q00UJCPU with the module QJ71MB91 connected to the slave device via 485 channel . This plc takes some values (like current/voltage etc). i dont have access to this plc cause he is on guarantee on another service company. So question is... How to connect to this device as a other plc FX3U via 485ADP-MB (and i think RS command) module in parralel to QPLC already working link? Is this possible without harm QPLC and all the data which he takes?

  4. FX3U and FX5U Modbus RTU comparison

    Hello. I have tested different type of communication between by rs485 fx3u and fx5u. On fx3u side used fx3u-485-adp-mb. In case of N:N and Parallel Link fx5u is more comfortable than fx3u. But, modbus rtu not so good. I made 3 tests: 1)FX3u master with ADPRW function; ADPRW in fx3u supports wider count of modbus functions, most usefull for me is H17 (Read/Write multipleregisters). But when i send telegram to Fx5u with this function, fx5u fall in error (recieved unsupports serial com functions). i have checked instruction manual on ADPRW - FX5u doesn't support H17, only H03 and H10. For read/write from fx5u need to use 2 instructions on FX3u side. 2)FX5u master with ADPRW function; In this test ofcourse i tried use H17, but result was expected - error. 3)FX5u master with predifined protocol. In this test using H17 function on Fx5u side was successful. Conclusion: FX5u better use as master for modbus rtu communications via predifined protocols, and if it used as slave need remember that it doesn't support H17. I hope this information will usefull for sombody.
  5. FX3U PLC WITH OPTIDRIVE E3

    Hi can anyone help me to undestand more about modbus RTU between fx3u with optidrive e3 ?? I'm using rj45 with fx3u 485adp-Mb for the connection.

  6. When M8029 off ?

    i try to use M8029 to be able run pulse in sequence, i mean i can't use regular PLSY or DPLSY, it doesn't work. So i add M8029 to help clear it and make the plc able to make pulse again. But the problem, when the sequence is finish and i need to start again, plc doesn't give pulse again because the memory that set it on is already reset by M8029. how to set it on again or reset the M8029? By the way, i'm using FX3U-48MT. Thanks,I would really appreciate your help.    
  7. In general, this control PLC program is written in GX Works. I did a simple visualization on TIA Portal v14 (WinCC RT Advanced) and I would like to now test it on Mitsubishi FX3U driver with ENET Module. I do not have much experience in this kind of thing, I'm still learning. I know that someone previously made a visualization in LabView and downloaded the tags from the PLC using NI OPC Server. Someone also did visualization in iFix and also downloaded tags through server opc. I do not know just how or what program to download tags in PLC so that I can no longer use it in visualization in TIA Portal. Unfortunately I still have a connection problem. The driver is connected to the router. From the connection options with RT Advanced I chose in the connections tab Mitsubishi and entered the appropriate IP. Still nothing. I do not know if the lack of a connection can be related to a virtual machine (VM Vare Workstation 12) on which I have TIA Portal installed. The driver pings but can not connect. I also tried using KEPServer EX to connect and unfortunately also failed. (I have information about the can not connect). Anyone know what program I should use? or had contact with such a problem? I attach a photo of communication from my station to more visualize the problem. Thanks  
  8. 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
  9. 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
  10. 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

    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

  17. FX3u PLC MITSUBISHI CONNECTION PROBLEM

    Hello everybody. My FX3u PLC doesn't turn ON, I connect to 24Vdc and nothing, not even the POWER led :( Any recommendation??????????? PLEASE   
  18. 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?

    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.
