  4. Crouzet Millenium 3

    Recently had to get a program out of a millenium 3 plc which I had programmed a few years ago but the cable would not connect.The only difference this time ,as my laptop no longer had a rs232 port,was the use of a USB to rs232 converter. Having trawled the web I managed to find the circuit of the interface cable below. It looks like the signal from the computer uses the negative going part of the pulses which aren't present on most usb to rs232 converters. Is this correct?
  5. Hello, Good Day All. I am facing this issue while I am going to copy old plc to new plc. but old plc having 4965 steps, once going execute this program to new plc its showing more than 8000 steps. please suggest on this. PFA.
  6. 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

    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  ?
  8.   Hello, I downloaded the program from the M251 PLC program, using the SoMachine4.3 environment. However, the downloaded program does not compile because the library is missing. The library is from a different manufacturer. Is it possible to find this library on the M251 PLC device? is there any way?
  9. 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
  10. Dear Experts I have Compact Logix L33ER processor for Hot Backup Redundancy Purpose in WTP application. Iam using Flexlogix 1794-OB16 DO outputs. Flex adapter for IO communication. Iam trying for Soft Redundancy from main processor to peer and peer to main processor . During Switchover from Main to Peer and Peer to main Processor, the DOs are cut off. While in the middle of the process if the Switchover of PLC happens due to failure of Main or Peer PLC, if the DOs are cut off, Should i Start the process sequence logic from beginning? I tried configuring the DO properties of  Communication Fail Behavior in output modules properties as "Hold Last Output but still the DOS are cut off during switchover. Then also Iam facing the problem of DO cutoff whle switchover. Iam having same program and IO configuration in main and peer plc generated through HotBackup tool. Please let me know if there is any way to Prevent DO cutoff while switchover . Also in Panelview HMI iam using 2 screens for Main and Peer PLC. While switchover the screens in HMI are showing in boxes. Please advise. Regards Krithik.K

  15. Hello everyone,  I have a Panelview plus 600 ( I know it’s old but I’m trying to get it to work). It’s on a yogurt bucket filler, I don't have any application to run or to do anything. What software do I need on a computer to be able to transfer it to the panelview. Is this even possible?  There is nothing in the memory right now but how to I program it and what program do I use?  I’m in the Los Angeles area and even willing to pay for someone to come and do it.  I need to get this to work, thank you so much.

  17. I am trying to online edit a program in a MELSEC QCPU, using GX Works2, but I keep getting this error "A file which does not exist in the PLC was specified" <ES:010a4022> Few weeks ago I had just online edited the same program in the same PLC with the same steps with no problem. There had been no changes to the PLC after that. Just all a sudden when I try to edit yesterday I get this error. Not an expert in Mitsubishi, just started learning the basics. Connection to PLC is by USB cable. Steps I followed to connect to PLC:    -Online > Read from PLC    -Select PLC Series: QCPU (Q mode)    -Select PLC side I/F Serial Setting: Serial USB    -Select all target program to Read, then Execute I am editing the file that I had just read from PLC Steps I followed to online edit:    -Online > Monitor > Monitor (Write mode)    -Execute the function below when mode is changed: Checked all    -Edit the program (basically just deleted one -||- contact and drew back the line)    -Compile > Online Program Change Then Bam! error get! "A file which does not exist in the PLC was specified" <ES:010a4022> I had tried Verify with PLC, but all results match. Is there something I am missing? Help much appreciated!
  18. Hi fellow PLC veterans, I am new in the PLC world so please forgive me if my questions read dumb to you..   I am just wondering if there are any newer PLC machines that can: 1. keep the program even after its battery is completely flat or faulty  (Is this even possible?) 2. allow users to copy and save the program somewhere so one can install the program again without the need/presence of the machine supplier What tools/software may be required?   Thank you for reading and look forward to your response :)

  20. Unconverted Ladder Code?

    Hi All, Please see attached screenshot: Whenever I want to save the ladder program or start simulation, this window pops-up. If I press 'yes' I loose the whole work. I tried to open existing program and modify it, but it did the same. When I clicked 'yes' I lost all modification and just the original program remained. (I made the program in the morning, opened and saved many times but it started popping this window later.) I work with FXCPU series, FX3U/FX3UC type, simple project in ladder. This worked well but now is not anymore. I use Melsoft GX Simulator! Can anyone advise why this is happening? It is very annoying! It is pointless to work on anything now! Many thanks

Help would be greatly Appriciated. Thanks
  22. 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
