  1. Hello Mrplc's members I have a Korean version " goldsec Moj2" of Mitsubishi plc A0j2 I need to know the right software for it And how to get it I tried GX Developer but it didn't work because it have only A0J2h type And I tried melsec medoc (version 1.64) but it didn't have A series CPUs
  2. Hi, I have the following configuration where 4 PLC panels, with each having a Q12PH CPU and QJ71E71-100 module. All these QJ71E71-100 are connected to a HUB using straight cable. From the HUB one connection is going to an I-Fix SCADA which is already communicating with all 4 PLCs using MC protocol. I want to send data from 3 of this PLCs to the 4th PLC in the same network using fixed buffer communication. Can anyone provide a sample program for the same. Send and Receive side. I am using GX Works 2 for programming. Your help is very much appreciated.
  3. Hello all, I need to read device memory mostly I need to read R registers from PLC L26. I read device data, but inside of table, I can't find R or ZR registers. Can you help me?  What I did wrong?   BR KS  
  4. Alarm Comments Not Showing on GOT

    Hello! Im trying to set up Alarms on my project using GT Desisgner 3. My GOT is a GS Series, and my PLC is a FX5U. I usually just do a multi state lamp with descriptions for what's happening on the machine, but this system is much more complicated, so id like to do an alarm screen. I found a few sample projects, as well as tried both the Simple and User alarm tools on my own. However once everything is set up, when an alarm is triggered, the comment for that alarm is missing... The alarm time of occurrence, as well as turning green when its resolved all works on the screen, but i cant figure out why my comment doesn't show up. When in my project, all the "previews" of my comments show up great and are all there, just not on the screen itself...   Any help would be greatly appreciated! Thanks!
  5. Hello All,   Semi-noob here with Mitsubishi PLCs. I'm starting a project in which we are upgrading an existing A Series PLC with the Q.  Is there a datasheet somewhere that lists compatible software within Mitsubishi's lineup? I had no luck in searching their site.   Also, (in the same project) the existing network uses DeviceNet. I have the Q series compatible card for that - but within what software does one configure the network?   Thank you.
  6. Hi Everyone,   I have  NT31C-ST142-V2 and it has a prompt of "System Program not exist or incorrect." I am trying to transfer via NT Series System Installer but I am getting a time-out error. I have Xm2S-09 serial cable with ATEN serial-to-USB cable.I know it is not broken since I can still Upload/download on a CJ2 PLC. I just want to know what other things I can do upload a systemprogram. I have seen a comment on this site that he remove the battery then tried to upload again.   NT is almost 15 years old. I have a back-up program.   I can't seem to upload by this time for pictures of theH MI and the screenshots of software .
  7. melsec medoc error

  8. The CC-Link system on a machine has been intermittently dropping out.  Normally the Link Scan Time runs at a solid 87ms.  When the system "drops out", the link scan time will increase.  Sometimes double, triple, or go up 10x. It happens when the machine is running or when it sits idle. There are 33 stations on the network.  The same stations do not always fault but sometimes all of the stations will fault at once (as seen in the attachment pictures.) We have changed the main QJ61BT11N, the processor, the Q62N power supply, the main backplane (base unit), all cards on the main backplane.  Is it possible for one station or one of the cables to create a network wide problem?  Any ideas thrown at us would be appreciated. 
  9. Unable to read comments

    Hello, I seem to be having trouble reading comments from PLC in GX Developer.  The PLC is an ACPU, Everytime I try to read comments using GX Developer I get the following error. "The comment was not read correctly". I found an old project from this PLC that has comments, But im unable to read any current ones. Anyone experienced this before?
  10. GXWorks 2 Comment Translation

    Hello, I was wondering if any of you have experience translating comments. To be more specific, I have been tasked with translating all of the comments in my plant from japanese to english. We have many different series of PLCs, but they are all mitsubishi, and I will be using GXWorks 2 for 99% of them. I had the idea of writing the comments to a CSV file, Translate them there, and then just read them from CSV back into the project. I have tried numerous methods, but it seems the CSV loses format and isnt able to be read back into GXWorks. Some of these comment files have almost 10,000 comments. Do any of you have any suggestions on the best way to translate these comments over, in a more automated way than manually one-by-one.  Thanks in advance for any support you can provide!
  11. Hi everybody; could you please help me;i would like to learn how to convert a sinwave signal with analog input of my R60ADV8 module.How many samples should i convert ? what is the maximum frequency of the input signal? and how to  recover the sinwave signal in the analog output of the R60DA4 module? i can convert dc signals from sensors  and recover them in the analog output;but i have no idea how to do with sinwave signals. Sincerlly yours
  12. Serial comm with FX1N PLC

    I need to communicate with a Mitsubishi PLC using Matlab. To do that, I open a serial communication with the appropiate parameters (7,e,1,9600), and write an ASCII message based on the manual I have (attached). I have tried examples as the one in the attached image. The response starts with a 6, that is, the ASCII number for ACK, so something must be working. But the rest of the response is junk (149, 149, 149...), although its length depends on the input length (if I add terminator, the response is longer, and so on). I am completely stuck. Some information that might be helpful: I am using a Serial to USB converter that I have used successfully with other PLC (which used Modbus, so everything was easier) There's a VB application (of which I don't have the code) that is able to connect to the PLC (I need to connect directly without using this intermediate app). I have decompiled it trying to get some info, but was just able to confirm the 7,e,1,9600 parameters, since the rest of the code is too mangled to analyze The attached manual was sent to me by the guy who designed the PLC and its ladder code, so I guess it is the correct one I have tried the echo mode (TT) to no avail, response is always the same I have some doubts regarding the reading of a value (see attached image). Why is there a second message from the PC? Shouldn't I just need to read the response? GX Developer tells me that the address D8120 (which is supposed to define the comm format and protocol) contains a 0, which seems weird. Any help or hint would be greatly appreciated.

  13. We have an application using a Mitsubishi L02CPU-P with a built in ethernet module. At one time the TCP/IP interface became irresponsive and a hard reset was required. The device is configured for binary communication and works fine using a GOT therminal and also operates fine when queried from a GX Works application. During debugging of a custom MELSEC application the TCP/IP interface stopped responding and could no longer be located using GX Works and the GOT terminal also lost contact. The L02CPU-P continued running the control application, but could no longer be contacted. The only way to recover was using the L02CPU-P reset button. I have heard developers being restrictive using the TCP/IP interface remotely over VPN and unstable connection due to the risk of hanging the device and not being able to recover without a personal visit to the device. Any experience from L02CPU-P devices requiring hard reset to come "online" again? Or does it enter some default state due to some internal exception handling?
  14. LOCAL MELSEC COMMAND

    Hi everybody,  Is it possible to send MELSEC commands to oneself, locally, not using the phiysical ports? I would like to use some commands described in the "Communication_Protocol_Reference_Manual_(MELSEC)" to get some self-management functions in my PLC.  For example, in OMRON this is possible using CMND instruction and setting the FINS address to 0.0.0 in the parameters of the instruction. Thank you very much. 
  15. Conversion from A to Q

    Good Evening everyone, I do realise that this has possibly been done before but quite a few years ago and the links no longer seem to work or links to Mitsi pages that are in Japanese, so please excuse me. I have soem A series PLC kit that needs replacing and I have bought all new Q series stuff to replace(where possible). I have been languishing a little on this project now for a few months but need to get moving. I purchased a GOT HMI and got a good deal on the HMI and the complete Mitsubishi Software Suite the local Mitsi guru said that was all I needed to get the job done. But afetr delving into what came inthe box it seems I need a A - Q Conversion Support Tool https://www.mitsubishielectric.com/fa/products/cnt/plca/pmerit/renewal/case/support_tool.html However I cannot find the software on any of the DVD's that I have and I cannot seem to find a download. So I am stuck now. Can anyone help point me in the right directon? Any Help greatly appreceiated. Thanks in advance.

    i have a 800 series vfd drive that when trying to start has the STF function and stop on at the same time, does this sound like a plc issue or a wiring issue?
  17. Wonderware DASMTEthernet Driver

    I have a client who is duplicating an existing Wonderware SCADA/MELSEC Q Series with a Wonderware 2014 R2 configuration, which they want to maintain that version.  The driver they use is the DASMTEthernet, which is no longer available from Wonderware.  I'm looking for any lead I can find to get hold of this driver, or a good solution to resolve the communications.

  20. 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.
  21. Hey everyone! New member here, and this site has always been a big help!  I try to help other folks too, but a lot of guys are super quick on here.   I've got a problem using some obscure components. I inherited a sensor network at work that uses Panasonic S-Link and I need to read them from a Q-Series. Panasonic makes a module that slots into the Q Series called an SL-VMEL-Q that I have.   My question is:  Did I do everything correctly on my Mitsubishi side? I put it into the parameters as an intelligent module with 64 points and I put the correct address in for the start I/O. Is that all I have to do?  This is the first time I used a module that wasn't on the drop down list when you add one in GX Works 2.   I can read and write to the buffer memory, but I can't get the unit to send to or receive from the sensors. I think the problem is that there is no end unit on the S-Link line (I don't know if it's just a terminating resistor or what), but it previously worked without one, so I can't be certain.
  22. Dear sir, i want sample program for modbus tcp for q series plc
  23. Hi everyone,  I am trying to use Kepware to communicate with my PLC setup which is the iQ-R Series R08PCPU.  I read the documentation which is available at https://www.kepware.com/getattachment/3daf1ac3-5c76-49ce-bbfe-f0fb1015f6cc/mitsubishi-ethernet-manual.pdf I read through the setup for Kepware and the setup procedure for iQ-R series but it still didn't work.  From the documentation, it said something about "using special ladder logic to enable ethernet communications is required.", I couldn't find anything about this online.  Here what I did in addition to the documentation: - Enabled IP Packet Transfer - Ping the PLC's IP Address which was successful Does anyone have any idea what I didn't do to establish that communication between Kepware and R08PCPU?  Thank you in advance. 
  24. 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.
