  1. CP1E won't connect or run program

    Hi there! Today a CP1E-E10DR-D suddenly stopped working. RUN led was off and I couldn't connect to it via USB getting this error: "Selected port does not exist. Select proper port number from Change PLC dialog and press OK button", and automatic online function didn't work as well(it's not a cable/driver problem since I successfully connected to a CJ2 CPU using same cable and PC). Since I also tried to connect with the CPU outside the control cabinet with no success, I asume there is something wrong at hardware level.  My question is, have you ever faced something like this? My plan is to try to revive it somehow (maybe trying to locate any defective component in the PCBs or something). So I was just wondering if you have any advice in order to achieve it.  Thanks in advance!
  2. Trying to log into NA HMI, NA5-7U001B  Direct, using USB or Ethernet.  All attempts failed .. tho, it was easy to log into the NJ Controller, direct, with USB or Ethernet using the same PC. Then a window popped up.. saying the firmware needed updating in the HMI, and suggested launching the "update" from the same window... Then, after a few minutes.  a "update failed" was displayed on the window.. and the HMI screen changed to this: ..and the green LED went RED ... aaaaagh!   HMI no longer works... any idea why this happened, or the failure to log in happened.. or, what it will take to fix it? Please tell me it was something Omron did .... Thanks Much, Regards, ,Michael PS:  additional info..  I was using Sysmac Studio Version 1.1 .. because I could log in to the CPU (USB and Ethernet) and not the HMI.. I changed to another PC with Sysmac Studio Version 1.17 .. Now I was only able to log into the CPU with Ethernet.. USB login failed. .. and, so did any attempt to log in to the HMI (USB or Ethernet) It looks like if you use a new version of Sysmac.. better not have a device with  "old firmware" ..  I think it was the V1.17 that presented the window suggesting the Firmware Update ...  sigh!
  3. Hi there! I was working on EPLAN Electric P8 when suddenly, the program stopped working (mouse didn't barely move, couldn't click) which resulted in a blue screen after trying to close the program (didn't manage to force stop of the VMWARE process where I execute it).  So, the thing is I can open projects and all, but everytime I close a component window I get this error window: (S275024) Couldn't find setting USER.SYSTEM.GUI.Control.MGGrid.DeviceTagGUI.116.1002.LastIndex.index. And it happens when other different windows (for example when opening Layer Manager I get the same error with LayerManger instead of DeviceTag. Also, if I try to close Eplan by clicking the red X of the window, It won't close. What can I do? There's very little info about this error code in the net and I'm running out of ideas. Thanks in advance!

  6. CX-Designer || Get error history

    Hello ! I am an beginner automation engineer and my new task is to export all alarm/events that occured from NS5 HMIs. Is it possible to do this using the pc? I am currently using a card to get those. (using the "hidden'' HMI's menu, accessed by pressing and holding on the display).  Thank you very much!
  7. Hello, has anyone noticed that plenty (not all) forum posts are changed to quotes from TWControls? What is happening here?  Hopefully only a momentary breakdown  
  8. Greetings everyone, I have a TIA V16 project in which I set up 7 drives to communicate with an S7 1500 controller via RS485 using USS protocol. The drives are Simatic V20s daisychained to the bus and are properly terminated with resistors. I use the USS DRIVE CONTROL 31 function block for each drive all located in a single FC and all using the same single instance DB as recommended by Siemens. I then call this FC containing the FBs every 120ms from the MAIN OB. I then call the USS PORT SCAN 31 function in a cyclic OB set at 70ms cycle time. In each V20 i use PZD word length of 2 and a PKW of 4. Both setpoint and commands are sent through USS. What I have observed is every time take out incoming power to any one of the VFDs, the rest of them get F72 comms error and fail to communicate with the PLC. Is this behaviour normal? What causes it? I use an RS485/ 422 PtP BA module sending data at 19200bps. Strangely enough it doesn't show any fault even though the diagnostics interupt setting is enabled on it. What I noticed is that as I was setting up the VFDs one by one, the F72 fault on the BOPs only pop up on an already configured drives. So, the VFDs that hadn't been commissioned yet for RS485, but were already physicaly terminated/ connected to the PLC, didn't fault the bus when they were powered down. They only faulted the bus upon switching them off only after RS485 activation (post commissioning).
  9. Hi Everyone, I have FX3U 60MR PLC and TP1200 Comfort HMI, communication perameters on HMI are 9600,7,even,1 stop bit. The problem we are facing is, communication drops after approximately 12 hrs. Analog tags become ### and HMI also dont respond to digital change in plc. Then we Power Reboot HMI and communcation get established. After few hours, same error occurs. we have change the HMI. But issue remained same. HMI is programmed through TIA 13 and TIA 14. HMI also dont allow to change communication parameter. Any one can help please?
  10. Hello, I've connect CP1E with PM2120 with RS485 and already make ladder program to read voltage, current, etc. But the problem is the binary value (D1354&1355) are not appear, and there's error in D1352 with error code : 88 hex. Which is the description of error code is "Exception response", and i already doing some experiment by just making a simple ladder with RXD/TXD instruction and put D1352 addresses and still error, which is same like before (88 hex.). Can i just still do something with this error? Please help me to solved this error problem. *Sorry for bad English Regards, Steven.

  14. OMRON NS5-SQ10B-V2

    Hello, I have an issue with NS-5 HMI. During transferring new program into HMI, after rebooting I get message: ERROR No.10: file system error: please recover the system program. What is procedure from where I can recover this HMI? I didn't find  folder on CX-Designer under C:\Program Files\OMRON\CX-One\CXDesigner\RecoverUpdate. Is there other way to fix this ERROR? I download firmware and copy it to the CF card. When I insert CF card into NS-5, and after power on unit, RUN LED light become steady orange for 10seconds and than it become steady green. Screen is black and there is not possible to do (chose) nothing. CF card is original OMRON card and wasn't formatted. How to solve this issue???

  16. PanelView 1400e Download Issue

    I'm trying to transfer an application file to a PanelView 1400e and I'm having some difficulty. We currently have 4 of these in operation on machinery and we acquired a spare that I'm trying to get ready. All use the same exact application. I tried using a memory card but none of the PanelViews recognize any of the cards I do have at the moment so that option is out (though at one time we did transfer the applications this way so we did have at least one card that worked in the past). I was able to extract the application file from one of the PVs via Transfer Utility 32 on Windows XP. I am unable to transfer it back to the spare PV. I am using a 9 for 9 straight through serial cable on COM1 of the laptop to the 9 pin DB connector on the back of the PV. I match settings between the PV and the TU32 (baud rate, parity, error). I put the PV on Transfer Application screen on the Serial tab. I open up TU32 and choose the application file (approximately 86kb in size). If I select memory partition 1 for the destination, I get a dialog that pops up telling me that partition 1 is full and it shows me the size and free space on both partition 1 and partition 2. The size for partition 2 matches what I see on the PV on the Terminal Information screen (approximately 2200kb in size and same is free). When I then select partition 2 for the destination and click OK, it asks if I want to format the destination. If I click NO, the transfer fails because "User did not format the destination". When I click Yes to format, the PV starts formatting partition 2 and the progress bar goes up to 100%, then a message comes up that the format is complete, waiting for application transfer. On the TU32 screen, the format progress goes up to 11% then hangs and eventually reports that the format failed. I've done this a number of times and it is always 11%. However, when I click OK and then go back to the main screen on TU32 and once again select to transfer, the PV screen goes into transfer mode with a progress bar as does the TU32. No progress is ever made and eventually I get the 4209 error. 4209 error means the TU32 and PV are not communicating, basically. But I'm confused as to why they initially do communicate but only get to a specific point each time before communications stop. Any ideas? EDIT: Once I get the 4209 error, I click OK, and go back to the main TU32 screen. If I immediately click to transfer again, the progress bar on the PV disappears and a message comes up saying File Download failed-Ready for Transfer. If I click to Transfer again, the progress bar reappears but still no progress and this process repeats. Thank you in advance for any help you can offer.
  17. 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.
  18. 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.  
  19. 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? I attach my Gdrive for pictures since i can't upload pictures in here *The data that i sent is in ASCII https://drive.google.com/drive/folders/1GPXa1U1PLMU2WKmo4YRPe32wHHyVCGUv?usp=sharing

  21. 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?
  22. Hi all, New to the forum. I've been pretty much able to do the things I wanted with Beckhoff, but now I'm finally running into a problem I can't seem to solve alone. I'm trying to set-up Modbus RTU RS485 communication in Twincat3, using an EL6021. I've implemented a sample program from the Beckhoff website, but can't get it to work. I've got the feeling I need to properly set up the EL6021 but most information on the Beckhoff website is about the KL-series IO. Does anybody have experience with this? The strange thing is that, when I enable the function to read some slave's registers, BUSY is set and remains set. No timeout is triggered. I don't have a slave connected yet but I would at least expect to see something on the output of the terminal, and then a timeout. I've bridged TxD+ and RxD+, and TxD- and RxD- and set 8000:06 of the EL6021 TRUE, half duplex mode enabled). A scope connected to TxD+ and TxD- shows nothing. Code added below. I've added a GVL called 'Variable_Configuration' with the following: VAR_CONFIG     Main.MB.InData AT %IB0 : MB_KL6inData5B;     Main.MB.OutData AT %QB0 : MB_KL6outData5B; END_VAR And then the MAIN: PROGRAM MAIN VAR     bIoSyncMaster AT %I* : BOOL;     MB : ModbusRTUmaster_KL6x5B;     MBLedDriver : ARRAY[1..10] OF WORD;     tmpExecute : BOOL;     bError : BOOL;     bBusy : BOOL;     iErrorId: MODBUS_ERRORS;     iNoDatByteRead: UINT;     count: INT;     freebyte: INT;     TxError: INT;     TxBlocked: BOOL; END_VAR MB(     UnitID:= 41,     Quantity:= 4,     MBAddr:= 16#0020,     cbLength:= SIZEOF(MBLedDriver),     pMemoryAddr:= ADR(MBLedDriver),     Execute:= tmpExecute,     Timeout:= T#5S ,     BUSY=> bBusy,     Error=> bError,     ErrorId=> iErrorId,     cbRead=> iNoDatByteRead);      MB.ReadRegs(); count := MB.MBMaster.com.Buffer.Tx.count; freebyte := MB.MBMaster.com.Buffer.Tx.FreeByte; TxError := MB.MBMaster.com.Buffer.Tx.Error; TxBlocked := MB.MBMaster.com.Buffer.Tx.Blocked; tmpExecute:=FALSE;

  24. I have a Siemens HMI 6AV2 124-0MC01-0AX0 in my machine. I want to clone the display on the HMI to PC/Laptop. My question is: 1. What software that I need for this task? 2. What kind of interface that I need between the HMI and PC/Laptop (for example ethernet cable, etc)? 3. Do I need to communicate with PLC connected with HMI or can I just connect with the HMI? Thanks in advance for the answer.
