  1. Hey Everyone,   My company decided to purchase a piece of equipment from China, and I have the pleasure of updating its terrible existing controls. We were given the PLC program by the manufacturer, so I was able to make my changes pretty easily - or at least that would be the case if I could actually connect to the dang thing. The source program is indeed openable and editable via GX developer (the original configuration shows it as an FX3). I figured connecting should be straightforward, but I was wrong.    I initially used a serial/usb converter that I've used on some older Allen Bradley equipment (which worked fine for that). However, after no luck using it on the "Mitsubishi", I purchased a different cable that I found recommended on this forum (Tripp Lite USA-19HS - https://www.alliedelec.com/product/tripp-lite/usa-19hs/70101537/?gclid=Cj0KCQiAj9iBBhCJARIsAE9qRtB_n8TVAnJdFyYokoEu42W6H6LaT4kVsgJQI1qvPUsUF3rFviKpbt0aApLHEALw_wcB&gclsrc=aw.ds). Still, no luck. I've tried 7E1 and every baud rate possible, as well as some other bit/parity configurations (and yes, I've verified that I'm using the right com port, as well as tried moving the converter to different ports and trying those). Nothing seems to go through.  I have almost no experience with Mitsubishi beyond a couple of FX5s (which have worked fine, but I connect to those via ethernet). Any help would be greatly appreciated; if I can't make these changes, I'm going to end up rebuilding the whole cabinet with a PLC I can rely on.   Thanks in advance.
  2. Hi,     I'm trying to communicate Omron CP1E unit with PC via serial port using hostlink protocol.  I need to read the Timer/Counter SV value and write the timer/counter SV values to the PLC.  I'm able to use other C mode commands (like RC (timer/counter PV read), WC (timer/counter PV write) etc.) but when I give the command for Timer/Counter SV Read 1 which is R#, I get the response as IC (Undefined Command).   How do I write or read the timer SV Values?  Example command and response : @00R#TIMH001028*  (TIMH is the high speed timer, 0010 is the timer number and 28 is the FCS) Response: @00IC4A* Is is that CP1E doesn't support these commands? If so what is the equivalent command that I should send inorder to perform this? Please help.  
  3. Hi guys, so i'm trying to send data to plc omron cp2e-n40dra via RS232C, I use RXD and TXD but it looks like my programs are wrong, the indicator of RS232C are on everytime i send the data so it looks like PLC receive my data but when i see it in memory PLC D i can't find any data stored. Can anyone help me please?

  5. Hello,  When i get error 2003 with sktTCPAccept what is causing it? Can it be caused if something was left open from previous session, is something wrong on server or client side? From F1 help i think error causes can be narrowed down to either open/close processing is in progress for SrcTcpPort although it doesnt specifically state that it causes error 2003. After closing port is there delay needed before i can use sktTCPAccept again?

  9. Error Indicator on FX3U-ENET-ADP

    Hi all, I have finished installing ethernet adapter module FX3U-ENET-ADP on the FX3U-48M PLC. From the ethernet module, i connected it to a wireless router and then i am planning of connecting to the ethernet module using GXWorks 2 on my laptop through wireless router. On the ethernet module, the error indicator LED is on (red). From the FX3U-ENET-ADP, it means that there might be setting or hardware errors.  I am asking if i have missed some steps on the installation process and if any of you have experience with similar problems. Thanks in advance for the answers.

  12. 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!!

There is no error on the slave evices.
  14. 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

  16. 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!

  18. GT Designer 3: Label import error

    Hello. When trying to import the labels from GX3, i keep getting an error saying the project cannot be opened. Has anyone encountered this error? Cheers
  19. Folks, we have a set of Mitsubishi Q12PRHCPU (redundant) running effortless since many years. CPU-A as standby and CPU-B as Control. Recently we noticed BATT low alarm on CPU-B. So we arranged for a spare battery Q6BAT and started the procedure as per manual(attached procedure and flow chart). We did memory copy from Control to standby (as prescribed precaution) and did the Reset of Standby PLC CPU-A. Memory copy from B to A completed successfully 100%. But the BACKUP LED did not turn Green from Red & Error LED kept flickering on standby CPU-A. CPU-B remain in Control but backup LED turned RED. From system monitoring we found that there is a Error 6000 (FILE DIFF.) observed in One of the .QPG (program 00-MDBUS.QPG). We tried to reset it but were not successful. We are surprised that why does the program differs when it was copied from CPU-B to CPU-A using the memory copy. Still we did the VERIFY and found no difference between the programs in CPU-A & CPU-B.  Can anyone explain the cause of this issue and the solution. Please note that the CPU-B is still in control and plant is running. Backup LED on both CPU are red which means (redundancy loss) and error LED on standby CPU-A is flickering RED. There is no error in the CPU-A (Control) -we checked this using the GX Developer. Also attached here are the image of the error and error help. Thanks in advance.

  23. Hi everyone! I got this machine with a CP1H PLC and NS8-TV00B-V2 as PT. I was told that they were working fine, but suddenly, It appeared a communication issue: black screen and "connecting..." at right bottom. I dont know if It is a configuration problem or some hardware damage.  These are the configuration in the PT and the PLC. The communication is through RS232 Serial.  I tried to communicate another PT screen with the same communication settings and IT WORKED!. ' I've been thinking that, perhaps, the serial port A is damaged, I have tried to set port b, but I havent could. How can I configurate PORT B??   THANKS...
