  1. 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 :)
  2. Hello all, is anybody out there who may read out a program that is stored on a telemecanique cartridge (more or less of 1993)? Program is still running on a TSX 47 40, but have an identical second cartridge. I would send it to him/her even if international post and do not necessarily require the cartridge back. Would be great to have the program as a text file / pdf / hardcopy. Any help appreciated!! Best regards Stefan
  3. Hi all  I need help with communication between Mitsubishi L06CPU-P with Siemens S7-1500 by Modbus TCP. It's necessary to send data from L06CPU to S7-1500, but I don't know anything about mitsubishi and gx works2.  Picked up some pics how I did it, but I didn't verified how it works. Can anybody help me with this? https://ibb.co/8KDmg5x https://ibb.co/Jm8shCx   edited: I also found LQnUDEModbusTCP_GW2_with_FC_V120 library, but how it works I dont know
  4. Hello, I'm trying to use Mitsubishi GX Works 3 version 1 for the first time and get a 'memory is insufficient' error window when I try to open/start a new project or if I try to open a PLC project a co-worker made. I am using Windows 10/64-bit, company we purchased the software from says they are using it on windows 10 without issue. I get the error with no other programs running, have 6 GB RAM, and have 90% hard drive space available. I have monitored Task Manager while opening a file, RAM usage seems fine, and have tried opening with "Run as storminess".  I have tried uninstalling the program using the window "uninstall or change a program" - is the a different way to uninstall this program that will wipe it more completely? The install CD has Disk1, Disk2, Disk3(DocFX) sub folder , Support folders - I ran the .exe file from all 3. Does anyone have any suggestions? I am able to open an HMI project in GT works 3 without issue. I attached a screen shot of the error. Thanks so much!!
  5. Hi All, Have recently embarked on a project that has required me to change over to GX Works 3 in order to link an IQ-R120PCPU to a Citect 2018 SCADA package . In days gone by under IEC Developer and GX Works 2 it was quite easy to establish communications between the programming package running in simulation mode and a running Citect system using the MXCOMP driver via MX Components to perform offline testing. Can't seem to find a way to get it to work under GX Works 3 though, has anyone tried a similar setup Simulated logic in GX Works 3 is running fine and can modify the IO from inside MX Components "PLC Monitor Utility" program so there is no issues there, just cant get Citect to communicate. MX Component comm's has also been proven reading/writing variable to an excel sheet with GX Works 3 in simulation mode also. Attached are the files for getting GX Works 2 up and communicating to Citect 2018 via the same method i am trying to get working in GX Works 3 in case anyone ever needs to use that method. Any help would be appreciated.     GXWORKS 2 & CITECT 2018.zip
  6. Dear all, I am trying to convert project from GX Works2 ( FX3U) to new GX Works3 (FX5U). Problem is that I am using disabled Compile conditions2 in GX Works2.

  7. Password for GX3 Files

    Hello We use to protect our files from GT Designer3 with a username and password. So, I can only open the project if I know the user and password. Very handy. I found that function not in GX Works 3. The field "User management" in "project" menu is disabled (grey). So, I surely miss something.  Can somebody help? The manual only tells about Block and CPU security.  Thanks!  
  8. I am looking for how others have set up vertical axis motions using the Kinetix 5700 servo system. I have a 2 axis pick/place unit with a horizontal axis (X @ 2500mm) and vertical axis (Z @ 1200mm) that works as designed during normal operation. X axis has no holding brake and Z axis has a factory installed 24vdc to unlock brake. There is a GuardLogix L81ES control system that handles the safety and control. On pressing E-stop/opening Gates the vertical axis will stop the motion, apply the brake and hold with no problems. (2198-D032-ERS3 Drive, 2198-P031 Bus Power, MPL-B430P-MJ72AA X Axis, MPL-B330P-MJ74AA Z axis) The issue that I ran into was an accidental download of the program without activating the e-stop and the vertical axis dropped unexpectedly when entering program mode on the processor. I am aware that this instance was my fault as the programmer, however I am also concerned that this might occur again in the future if the controller ever enters fault mode or someone else completes a download. I have done some investigation with the "ProgrammedStopMode" parameter on this single motion axis and attempted all 5 options and the vertical axis still has a free fall drop for a second before the brake grabs hold - so evidently this is not working for me. (Page 24 of Vertical Load/Holding Brake manual - https://literature.rockwellautomatio...t003_-en-p.pdf) I am curious if there needs to be something done elsewhere as the X and Z axis are set up as coordinated axis? I also am unaware if I need to preform some action/parameter with the bus power supply for this? The current state of the machine as it sits now is preforming a MSF in manual mode after 5 seconds of inactivity or 30 seconds in auto mode. This axis is usually in demand every ~22 seconds. This will shut down the axis after preforming a brake test on the vertical load and seems to function OK, however it is still in the back of my mind the issues mentioned previously if we ever enter a controller fault while indexing. Thanks for your insight

  11. Hi Guys   I am trying to change a profibus module on a Q02CPU from a QJ71PB92D to a QJ71PB92V, but when I try to download I keep getting the error Flash ROM writing could not execute rightly.   Now I can download and upload code thus I think the Cable and PLC power OFF is a null.

  12. GX Works3 problem

      Hi Guys, Can you help me out with this question The servo motor connected to axis-1 rotates in the forward direction when the M1 button is pressed, and in the reverse direction when the M2 button is pressed.

  13. What Is a PLC Communication Error?

    PLC doesn't respond to communication requests or responds negatively to such requests. A PLC communication error can occur between the programmable computer and the devices it controls or when the technician attempts to program the device. If anybody have idea then share i am fresher now i learn it from CETPA INFOTECH. I think this is the best place to ask.

  25. I am trying to get produced and consumed tags set up between 2 1756 racks with different ip's. The 1st rack has an ip address 172.28.6.3. The 2nd rack has an ip address of 10.81.105.8. Would this be as simple as adding an EN2T card to one of the racks and setting the ip of one onto the same network? Or is there a better way to do this?
