  1. Hi all. I am new to Autonics and Mitsubishi. I am trying to read and write the data of an Autonics TK series temperature controller using RS-485 with QJ71C24N-R4 coupled with Q00UCPU. I have the hardware setup as attached images. Software setup are as follows:  TK4 Settings: Communication address: 01-99 Communication speed: 38400bps Communication parity bit: none Communication stop bit: 2 Communication Response waiting time: 20 Communication write: Enable Mitsubishi Intelligent Function Module: CH2: Operating: Independent Data Bits: 8 Parity Bit: None Even/Odd parity: Odd Stop bit: 2 Sum Check code: None Online Change: Enable Setting Modifications: Enable Communication Rate Settings: 38400bps Communication Protocol Settings: Predefined protocol Task to be carried out: 1. Read SV 2. Read PV 3. Write SV I have the address for the modules but I am not sure how to communicate or the program which allows to reading/writing. I had tried to follow the attached PDF but i cant key in the first line as there is a bit with "G450" which has an error stating "the device No. is over usable range" and  "An unusable device has be designated". I hope someone here could guide me in writing the program, or any reference for me to follow.  TK-Q02H_RS485_EN_Technical_support_180823_W.pdf
  2. Hi! We have a GOT2000 HMI with a Q06UDVCPU system. During an investigation, I found that the address on the HMI (for example D10120) and the address in the PLC (D10020) are different. The value is the same, it appeared instantly during monitoring, but when I searched for it, didn't find it (I couldn't find the D10120 in GxWorks2, and couldn't find D10020 in GtDesigner3). The HMI's address is 100 higher. I never saw anything like that. Where is this difference can be set? Knowing this, I can navigate in the program..it's just annoying.
  3. FX5U Modbus-TCP Server (Slave)

    Hello everybody. I need a solution for Modbus-TCP server on the PLC. With the FX3U it would work with the FX3U-ENET module. The internal interface of the FX5U should actually be able to work with the library of the FX3U (FX3GModbusTCPServer_GW2_V100) or not? Because a socket connection is now possible. I would be happy about suggestions. Dave
  4. How can i limit MRJ4 servo load?

    Hello, I am beginner at servo and its driver. i am using MRJ4A driver and HG SR102 servo motor. i want to make my servo stop or alarm when the load is over the maximum load that i set by my self. what parameter should i set to limiting servo load even if the servo motor strength enough to lift the load.?

  6. Simulation of FX5 in GX Works3.

    Hello gentlemen. I am working in a company that makes SCADA software, and needed to do reading/writing tests on MitsubishiPLC's, In this case I needed to do tests on FX2, FX3 and FX5. I saw that Mitsubishi makes available the GXWorks 3 software that is possible to do simulations of FX5 and FX5u in it, but I can't connect in any way to the PLC being simulated on the company network. I put the correct IP in the ModuleParameter\EthernetPort configurations, I write a simple read/write program in ladder, and I use Star Simulation, but when I try to ping the PLC, I can't find it, much less talk to it via VisualStudio . How can I connect this PLC that is being simulated in GX Works3 in an external program?
  7. serial input string

    Hi  I'm quite new to plc but very new to mitsubishi.   I have an input string eg G+002.7 which represents a weight. I wish to take in the input string then move/convert to int omitting first char,   On other plc's i have been able to use a modifier like d200[2] then the no of chars. How do i achieve this in gx works3   Any feedback gratefully recieved   Paul  
  8. Alarms Acknowledge

    Hello experts, I have a problem with Mitsubishi, specifically about alarms and their acknowledge. Basically I would like to follow Siemens logic, i.e. when I have an alarm, I acquire it and only after this step can I reset it, so every time I have an alarm and want to reset it I have to acquire it first, but this means that every time I reset it and for some reason the alarm comes back to me, its acknowoledge has to come back working.  I hope I have made myself clear.  Does anyone know if I need to set something on GT Designer3 or do I have to adapt to Mitsubishi logic and do some programming on GX Works3? Thank you very much

  10. GX Works3 Projectlib Locked

    Hello, I have a problem that I need to solve in a PLC program has it's projectlib locked.  I work for a company that contracted a PLC programmer before my time to program their new version of their control cabinets. The company did not write any specific contract with the contractor and just relied on his work. The guy later delevered a buggy software that is kind of functional (the bugs came up at the commissioning after the guy was paid and now he refuses to help or to provide more consultations). I have as a task to freshen this up and make it work without bugs, the problem is that the Projectlib is locked and I cannot access the source code.  The only thing that I can changes that I can make to the code is to put some logical circuits between the I/O of the already existing function blocks, which solved some problems, but not all and it keeps one of the most important ones as well. Anyways, that's my story, so now my question is, is there and possible way of unlocking the projectlib? Any feedback would be highly appreciated. Thanks in advace!

  15. QD77GF Error D304

    Hi. I am using PLC Q06UDV wit QD77GF to operate 11 servos, it is my first time using QD77GF and CC-Link IE Field. I've done the parameter setting. but the qd77gf error lamp started to blinking. i try to check it in cc link ie field diagnostic and didn't find anything except the error lamp blinking in monitor view. then i checked system diagnostic , no error showing up but, only historical error when i started the power of plc. it show D304 error.  in manual book the solution are lengthen the operation cycle qd77gf, check the cable, and shorten plc scan time. where can i find this setting sir?

  17. weight batching system

    Hello everyone, i am making a weight batching system , my system consists of 9 tanks each tank have a specific raw material , the user should be able to add a formula through scada system so he will be able to specify each weight of each ingredient to add to the formula. i have managed a connection between my weight indicator (pt650d) and my plc (fx3g) through fx3g232bd module (RS232 communication) , the weight indicator send data in ASCII to plc that we can show on the scada system .  so how can i change the ASCII numbers that come from the weight indicator to Decimal number without changing the value so i can control a barrel that will add raw material from the tank to the scale untill it reaches what the user specify in the scada ??   
  18. SLMP Failures

    Hello all,  I am new to using Mitsubishi and I am having issues communicating with my Cognex Camera. I have the camera configured in Datamn Setup Tool. I have the Ethernet card configured and validated. I am able to ping both devices and get a response on the network. However, I received an SLMP failure in Dataman and there's no communication between my camera and the controller.  Please see the attached photos to view how I have the camera and PLC configured.
  19. File Transfer Protocol

    Hello I have a FX5U PLC that is performing some data logging (D-reg and Bit) through the CPU module logging configuration tool, sample time of 5 minutes. Currently the client is physically swapping the SD cards to retrieve the data. I wish to set up a File Transfer Protocol function to transfer the logging data to the C drive of a local PC. They will be connected via ethernet cable through a network switch but independent of any other networks or internet. Desired function of FTP: 1.      Data transfer every 24 hours 2.      Confirm SD card not in use (either pause logging function or carry out in between 5 min samples) 3.      Read logging data from SD card 4.      Write data to local drive on PC 5.      Delete transferred files from SD card to leave capacity for further logging operations 6.      Data logging instruction file (.llp) must be left on SD card 7.      Recommence data logging function I have configured the PLC as FTP Server and managed to view the contents of the SD card through windows file explorer on laptop with limited success (connection is intermittent and when access is possible, it does not always show updated/latest SD card contents) Is it possible to achieve the automated FTP using Mitsubishi and Windows software or do I need 3rd party software as well? Any advice on this would be hugely appreciated.   Many thanks.

  21. PLC Reset?

    Hi guys, I always wondering, what is reset when reset button is click? Does the setting from address D from HMI will be lost? Does internal memory of PLC is reset? Anything thats not reset? Or just reset sequence? Thanks.
  22. Hi, I'm currently working as an intern, and my job is to transfer the program from a schneider twido twdlmda20rt to a mitsubishi fx5u-32mr/es. The thing is, i've been in trouble trying to understand and "translate" from one plc language to another certain things, like the %MW, %SW and blocks, so if any of You could give me some advisory I'd bee fully thankful (I can't upload all the pics, so theres's the link to the folder) https://inacapmailcl-my.sharepoint.com/personal/nicolas_gonzalez206_inacapmail_cl/_layouts/15/onedrive.aspx?id=%2Fpersonal%2Fnicolas%5Fgonzalez206%5Finacapmail%5Fcl%2FDocuments%2Fscript
  23. Hi everyone,  I am new to Mitsubishi PLC. I am trying to see from where Run or speed commands goes to Servo. I have MELSEC FX2M-32MT with FX2N-1PG cards for the Servo and I am using GX Developer 8.91v  Also, I would like to mention that initially I found out that BATT V light was lit so here what I didi. >I replaced the battery within 20 second while powered ON. Before changing the battery I took upload of the program successfully.  >I have cleared PLC memory and re downloaded the program.  > Checked Memory addresses M8005 8006 both are Low.  Now, when I am trying to run  my machine it is not giving output to two Servos while a conveyor operates when started from the HMI so it means program is inside PLC, right ? Program is attached if someone wants to have a look.  labeling mc 300322.rar
  24. Selecting alternate POUs on FX5U

    I've to modify this program I wrote back in 2015 and modify the sequence in Seq100Bins. I'd like to work on a copy Seq101Bins during development and toggle between the two POUs. I can't find or remember how the various POUs are called. In most other systems I've used they'd be called from the MAIN / Program but the logic isn't in there. Can anyone jog my memory or correct my understanding?
  25. I would like to send ascii data  to other devices using RS232 interface. and the example format is "0009" (it is product counter machine marking). how can I do this? I am using q03ude, I usually convert 1001 to ascii using BINDA and use the last data (01). but, when it double word data e.g. : 100009 the last data is 9 and null, not 09
