  1. Hi everyone, did anybody do rs485 communication with Non-Protocol Communication of Mitsubishi type FX3G-485-BD via sensor supppor rs485 ..help me,thanks  
  2. Hello. I am trying to make a serial RS 232C connection between Schneider Magelis HMIGXU3512 and Omron PLC CP1E. However, there seems to be a communication problems between both of the equipment. I am using cable XBT Z9740 for the serial communication cable. The format used is 8.2.N for both equipment. The baud rate is 115200. No Flow Rate is choose. Anyone can help with this kind of problems?
  3. Device point error between Parameter and PLC

    Hello all, I am a beginner with PLCs programming. I have an issue on GX Developer programming software from Melsoft trying to program my Mitsubishi Q-series PLC. CPU is Q03UDCPU. When the program is written and I try to upload it to the PLC, with the write to PLC window, I check -Program -- MAIN and -Prameter -- PLC/Network/Remote, click EXECUTE and a message appears : "Device point that is set in parameter is not match the device point in PLC". I can't fix it. In Parameter - PLC Parameter - Q parameter setting (window) - I/O assignment tab : I have (see image). Whe I use CHECK button it says there is no error. The X41 input device is plugged on slot 1/00. I am making this folowing the instructions a PDF I found on the Mitsubishi electric's wesite : Q-series basic course (for GX Developer). Thanks for the help, A. S.
  4. Greetings everyone. I'm new here. Hoping to get help to operate the Omron V400-R2 barcode to the Mitsubishi QJ71C24N so that they can communicate the two devices with the correct method. PLC: Mitsubishi: Q03UDVCPU; barcode: Omron V400-R2; serial communication module: QJ71C24N. I use RS 232 communication cable, I have tried using predefined protocol and non protocol procedures but still can't communicate the two devices. I really appreciate your help.
  5. Here is a link to a thread on a recent post showing how to communicate serially to an Omron PLC using VB.Net. This uses the Omron Host Link serial protocols. (C-Mode Commands) It will read 10 DM registers and display them on the form.   http://accautomation.ca/implementing-the-omron-host-link-protocol-vb-net/ Here is the source program that can be downloaded.

  6. Please assist me with the following; regarding the ME96SSHA-MB Power meter data transition with Melsec-Q series PLC; We acquire to read various values on dedicated Modbus storage address registers at the simultaneous into a Melsec-Q series PLC via Modbus (TCP or RTU)  for calculation purposes. Naturally, since the reading of these variables are to provide accurate instantaneous results, it is a requirement that these values are to be read at one scan.   However, as can be seen below, there is a gap in address register range – of which, if all of these are scanned simultaneously, yields an exception error when read. This error is only avoided by scanning these data sets separately – which is not ideal for our application – since accuracy in calculations is imperative.

  8. CX-Simulator

    Hi guys, Do you have experience or know any good guides to set up a simulation case like this: - Simulating a PLC program such that the "PLC" is accessible on the Ethernet (for example just locally). - In addition, setting up the PLC settings with FINS protocol such that it is possible to write to the PLC with FINS protocol from another device. The first part is  most important. Best regards PC_VS_PLC
  9. Hi, I have a omron PLC in a FINS network. Should there be any problem connecting another PC to that network and ping the PLC?   I somehow don't get any response when I try to ping the PLC from a PC.   Best regards
  10. Hello Everyone, I am studying the overview of the CIP Message Communications in Omron's "NJ/NX-series CPU Unit Built-in EtehrNEt/IP Port User's Manual"  but not all is clear for me. Could anyone suport me with the WireShark's capture of the PC <-> Omron NJ  CIP communication session  ? I'd like to see in 'real' world the CIP packets used to read/write of Omron's NJ Global variables.   Thanks in advance Zbyszek  
  11. Profibus Function Blocks for Q2ASCPU for Melsec ST Lite RIO inter-connection. Please assist in advising the attainment of such blocks - if any existing. Thanks
  12. MES interface IT

    Can I use just QJ71MES96 without the Q12DCCPU-V in MES interface? I am not sure if Q12DCCPU is still needed when monitoring only 1 PLC(Q03DVCPU) and sending data to a database.
  13. Is there a list of words, particularly d0000- dxxxx, used by got hmi that is not apparently found in gx works program but cannot be used since it will affect the hmi, like turn off hmi screen. For example i cannot find d14 in program but it is being used in hmi but not in buttons, rather configuration. Plc and hmi Connected via ethernet, udp protocol
  14. Hi, I'm trying to set up a TCP communication between a Q03UDECPU and a Beijer E110 panel  I've tried both TCP and UDP as "communication mode" in E-Designer. nothing seems to work.  What I'm I doing wrong Se attached files from E-designer and Gx IEC Developer
  15. Hello all, I have 7 Q series PLCs on a Melsec net/h network, Ladder Programming none of that fancy smancy ST stuff LOL. Were running the QJ71LP21-25. Now to keep it short I have used all most all my devices in my Network Range Assignment. I can not set up low speed range as I do not have enough Link relays and registers at all stations. No memory for more devices just trust that I can not do it... However I have an abundance of File Registers ( no I cant buy B or W in the PLC File params, well I can but it wont help because only one CPU is UDE the rest are H.) I have a project in which I must see about 50 words for each Station at every Station. I figured while I am setting up a Transient Transfer I will make a bunch of extra room for future updates and junk. My answer good or bad, is to set up some Send/Recv commands and do some Transient Transfer. I think I have it just about all figured out just a few questions. I have two manuals I have been getting my info from Q MELSECNET/H Network System Reference Manual ( I think SHNA080049)  and the Melsecnet/h training manual.  1.Any one have any better manuals that better cover transient transfer? Or that are new enough to mention GX Works2 instead of Developer? 2. Is there a max device for each send/recv? (I keep thinking it is 980 per station but no idea where I got this number)( I will increase the max # of transients in the supplementary settings under network range...) 3. Any precautions or advice like, Hey don't do this, I did this once and.... 4. It looks like as long as I use different logical channels for each station I should be able to send and receive multiple "messages" at once with no error?? (I will test this and look for the "no room in receive buffer area f222 error)  5. Will this slow down the Cyclic transfers (I will be watching the SW006D and so on to make sure it does not slow my regular transmission down.) 6. I will be using several special relays and registers in the program of course. Any I should use that are not obvious?  
  16. latch clear operation

    what is latch clear operation and how is it triggered? Q03UDCPU connected to AB contrologix via ethernet sends data to L or latch relays and i read that it is only reset via latch clear operation. will for example L02 turn off if the bit is not triggered in the contrologix side?
  17. overwrite linked word

    is it possible to overwrite the linked word coming from the other station as stated in this refresh parameter?  http://prnt.sc/etejvj I will do OUT W703.11 which is written in the station 3 but I dont have access to it so I am asking if this is possible.

  20. MC protocol and SLMP protocol

    Hi everyone Is SLMP protocol and MC protocol are same?? what is the difference between these two protocols??   Thank you in advance
  21. Hello all, I'm using MC Protocol Format 4 to communicate with a VB6 application on a PC. I want to make some slight modifications, and I am getting a sum check error being returned by the module to my application. I believe (haha) I am calculating the sum check code correctly for Format 4 as most commands do work (reading for example). I was wondering if anyone knew of the buffer memory location on the QJ71C24N card that stores what the card is calculating for the sum check? This way I can have a troubleshooting tool to see what I am calculating wrong. I have looked through the manuals (application/basic) for the C24 already as well as the Melsec Reference Protocol manual.  I have attached the error code for reference, again, I am only looking for what the C24 calculates as the sum check code. Thanks  
  22. F-MPC04 RS-485 Protocol

    Hello! Anyone here know about Fuji Electric power monitoring unit F-MPC04? Does anyone have the Communication Manual for this unit? I need to find the F-MPC Protocol which it used with RS-485. I know it is accessible via MODBUS RTU, but there is already a system exist using this F-MPC protocol. It seems Fuji doesn't publish this protocol for public, but there should be a document somewhere :D   If anyone knows please kindly reply here. Thank you

    MC Communication Protocol
  25. communication with PC

    I have a project where I have to read I/O, and potentially initiate programs on the Mitsubishi PLC. Seems I can use the Melsec Protocol but I have some difficulty getting started. I can communicate via Ethernet using GXWorks 2 so hardware-wise there shouldn't be anything wrong. I'm using QJ71E71, Q06HCPU, QX42, etc. Initially I open a UDP socket to the correct IP address and port (copy the port from GXWorks) and attempt to issue a request 3E/Binary, specifying the network, PC, Module IO, and station and it always times out. Is there any source code that just does a basic read of a memory location? I'm using C++ but I should be able to understand any code sample in VB, C, C#, or others. Also, is there any issue with multiple connections to the PLCs. Right now I quit GXWorks before I test but is this necessary. Thanks, Jeff
