  3. Can USB-A2 connect PLC through PROFIBus? Can profibus connect sub-stations directly for diagnosis?   There is a 3152dp, which communicates with the sub-station through dp, and it is inserted into the dp head of cpu. It is not connected by automatic mode, but can be inserted into mpi port. Do you need any Settings?
  4. Hello all, I'm commissioning a project and connected a 2 wire pressure transmitter Danfoss MBS33 060G3039 to a FX2N-4AD module attached to a FX3U base. When I connect a 4-20mA simulator it all works fine, my signal is correct 0-4000=4-20mA and my HMI shows a correct value however when i connect to the Danfoss transmitter a mismatch occurs. It starts with a 5,5mA signal at 0,0 BAR so my HMI shows already 1,0 BAR instead of 0,0. It seems, when I increase the pressure, that is is a linear up going signal. somehow I think it is a hardware connection because with the simulator at the input it works OK but I can not find an other way to connect than inthe manual. Is there an other way with resistors or something to allign the impedance to the PLC module? Best regards, Theo
  5. FX2N 4AD2DA

    Hi,    Doas anyone have any samples how to configure +10 analog outpu for china version of mitsubishi PLC , and how can i test if configuration work  ?
  6. 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

  13. Dear all, I have a FX2N-20MR chinese semi-clon of a Mitsubishi PLC. It has only a serial DB9 port that cannot be removed or exchanged (which is possible in the Mitsubishi original PLC). I wonder if I can make a simple SCADA system using that port and just one computer. I am reading this post: https://forums.mrplc.com/index.php?/topic/9653-fx-series-and-modbus/ And I am wondering how I can do what it is suggested there in the second message:  to use a free FB block, available in GX IEC (but not in GX Developer), which will communicate modbus via a standard RS232 BD board. Later on it mentions a library called ModbSFX. That message is from 15 years ago so I am wondering if now there is some other way to do it, perhaps some other software has that functionality? I don't have GX IEC. I am a student trying to make a project so I would like a cheap and simple solution. Any help to do so will be very welcome. Thanks Regards Marcelo
  14. GX WORKS 2 with MX component

  15. Dear colleagues, Maybe someone faced with cylindrical grinding machine G32P-100NC model by Belor Co., Ltd or Supertec and have a set of programs for it? The program of A2N-20GM (FX2N-20GM) module has been lost. 
  16.   Good afternoon, dear specialists. Recently, only without preparation, I began to set up communication between the scada and the PLC. The problem is that RSLINX LITE (v3.90.01 CPR 9 SR9) sees both PLCs on the network, but one of them gives a problem with reading data, or rather, the data monitor does not load at all (or shows a red cross (which means there is no physical connection to the PLC)). But it responds perfectly = 1ms. Nearby is an old PC with an old RSLINX LITE (v2.41.00) that perfectly reads data from both PLCs. What is the problem? why doesn't the more recent program read the data? There is an even older PC on Windows XP on the Intouch scad, via OPC the "SMC" application also reads data without problems New PC:                                               Old PC:                                                still the third ancient PC: Windows 10                                         Windows 7                                            Windows XP RSLINX LITE v3.90                             RSLINX LITE v 2.41                             SMC (intouch) Status Not working                              Status Working                                      Status Workinп It was also connected via the "Ethernet" and "Ethernet / IP" drivers. I directly connected a new PC to the PLC and set up only one connection, still the result is negative. I would be grateful for any help! If I apologize for my English, I did it through a translator.    
  17. Mitsubishi FX2N Battery Error

    I got through a mitsibishi FX2N PLC and when i turned it on it was giving battery error. So when i checked it with system and run diagnostic so i found the same error. By visual inspection i saw that there us no battery in it and someone has taken it out. So my question is that how we are going to reset the PLC when the battery was not intact for how long whixh we dont know. I have the copy of program with me to upload it to plc but the actual issue is battery error.

  19. connection to omron CJ1M PLC

    I have an omron PLC (CJ1M type) at home which I would like to connect to, however, lately, I can't anymore.  I'm trying on two different PC's a newer and an older one, both running on windows 10. 1 is just mentioning a DLL error and I can't even start cx-programmer, the other one seems to work, however, when I try to go online it always fails I'm using a usb to serial device and after some searching on the net, I thought the issue was with the prolific driver.  I tried all kind of fixes, but nothing seemed to work.  I have now purchased another device, the XS8801 from usconverters and installed the latest driver.  I have checked if cx programmer is set to work with the correct port and this is the case. My knowledge is very limited but I would really want to connect to that PLC again, so hoping someone out here is able to help me. Thanks a lot

  21. Hi Guys I am currently configuring a profibus configuration using Gx Configurator DP. I need to 3 IO modules through a FX2N-32DP-IF. The modules I need to add are: FX2N-48ER(Intputs), FX2N-16EX and another FX2N-48ER(outputs). Do I need to download these modules GSD files and add them individually to the node?  If so, can you provide me with a link to these GSD files, as I am unable to find it?   Kind Regards Morne
  22. FX2n incorrect latch range

    Hello, I have an FX2N that got a corrupted program after the battery went flat. The PROG-E led is lit. I don't have a copy of the program, but I managed to read it from the PLC. Attached is the read program, it reports an incorrect latch range plus a bunch of errors. Any hints are appreciated. Thank you. Kind regards. backup_fx2n.zip
  23. Hi,   We have a company that is specialized in bandsaw machines, this is one of those machines: What we have done is hook up a wire encoder to the saw bow and the other end of the wire on the base of the machine. You can see a picture of it in the attachment. I have followed the manual of the FX2N-2AD module, the wire encoder requires the current input from 4-20mA, and I am getting a digital output, but this needs to be converted to show in millimeters on the HMI. Unfortunately I am only learning how to do this, and am not an expert in Mitsubishi PLCs (yet). Currently the only code we are using in PLC for reading the 2AD module is found in attachment. TLDR: Wire encoder giving a digital output, but now need code that can convert this value into mm.    
  24. FX2N-32MR Prog/CPU Error

    Hello. I first off I wanna say that I am completely new to PLCs and am trying to help fix my Uncles hydraulic die cutting machine that uses a Mitsubishi FX2n-32MR plc. It has CPU version 3.10 and ram memory and is giving him the error 6402. This machine was working perfectly fine up until a few days ago. I already know that the backup battery is toast. It was only reading 0.1 volts. I am trying to figure out if the plc is fixable, if this is a software or a hardware issue and if so, how to fix it and help save him $$$.  I have successfully communicated with the PLC using a usb to sc09 cable and have the following software installed: GXWorks 2, GXWorks3, GX Developer and MT Developer 2. I got the error 6402 from GX Developer. I have attached what I believe to be the Program that it has installed to the PLC, but all I did was save it after the program read it(it had an error while reading it) so I dont know if there is actually any data.  Any help or direction is greatly appreciated. I have attached 2 images as well. Not sure how helpful they may be. Default Program.rar
  25. FX3U Stop Reading Channel Data

    Hello Everyone,  Need help with reading channel data of FX2N-4AD with FX3U Cpu. I have added all the logic and it works also. Problem is that, FROM function stop reading/fetching data from FX2N-4AD after some time i.e couple of hours and value just hang. Like 502 or something, untill you reset the whole PLC. What could be the problem. For the further info, -I have connected the FX2N-4AD on the right of fX3U-64M. -There are two extension blocks FX2N-16EX and FX2N-16EYR also added to the right of FX3U-64M -Order of mounting....FX3U-64M > FX2N-16EX > FX2N-16EYR > FX2N-4AD > FX2N-4AD   I have tried using the 2nd special module connected at the end, but It showed similar problem after few hours of running. THis shows that both Special blocks fx2n-4ad are okay. There is something wrong with PLC maybe? Please help
