  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? 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

  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?

  7. Hi, I have problem with 5069-obv8s, trying to use it for a first time just to power relays and contactors. All outputs are in internal fault, even if their are not conected. The card is set to use single output as safety outputs. Additional power on LA+ and LA- ports is connected. I don't know what else should I checked to fix this problem. There is no problem in controler or this specific module just on all of outputs. Hope someone will be able to help.

  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.
  10.

I don't know what I have to do when I replace Module 1761-NET-DNI? Thank you very much
  11. I'm a young Controls Engineer at an integration company, and I need assistance.   I have a client that has about 330 different alphanumeric product numbers broken down by length and width. The operator must be able to select the product number at the HMI to pass along to the robot we are integrating. Is there a way to be able to have the operator select the product number simply, without having to scroll over 300 items in a single control list. The HMI is not chosen yet, so it can be GE, Rockwell/AB, or Automation Direct, but we are using a AB ControlLogix Processor. Racking my brain and I have little VBA/Scripting experience.
  12. I'm an automation tech in a tool and manufacturing facility.  Lately, we've quoted a few projects for customers that include tooling (stamping dies usually) as well as some partial automation.  The automation is fairly simple usually...motor, drive, actuator to transfer material in 2 axes, e.g.  The company president and quoting engineers don't think it's a big deal for us to do this, but I'm a little wary to agree to these projects.  I have 2 years experience doing all sorts of small programming tasks, wiring, control panel design and build, troubleshoot, etc. However, I also know that there are a lot of industry and safety standards to follow when you start machine building/integrating for customers.  The tooling build is straightforward and is our forte.  But we have no electrical/controls engineers, and we have no standards really for automation "builds".  I've done smaller projects for us and I'm trying to develop some sort of standards, but there was nothing like that when I came into this position.   Anyway, should I undertake these sorts of projects in your opinion or not? And if I would, what sort of knowledge/standards should I master in terms of liability and safety, and where would be a good place to start in developing a wiring/electrical schematic standard? Thanks for your assistance. Andrew

  15. 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.

  17. 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...

    Hello, I need to connect remotely to an OPC Server DA. In my PC I have installed several OPC Clients but when I try to connect to the server (therefore located on another machine) I get an "access denied" error. How can I authorize the exchange of information between the 2 machines? Thanks
  20. Panasonic servo drive

    HiI have a Panasonic Minas A5 servo drive trying to test in free run a Panasonic A6 servo motor, But as there is a mismatch between the motor and the drive, error 95.0 appears, which declares "motor automatic recognition protection". I'm looking for eliminating this error. (saying that cause in other brands like Yaskawa or some mitsubishi drives this error, known as combination error, can be cleared). I think maybe by changing some parameters this error can be cleared.Any idia?Regards
  21. Hi, I wanted to run an SMC linear actuator and found this error in axis settings: No device is assigned to the required item. More strange is that I checked one of my old programs in which I ran a Fastech motor (with Ezi driver) by Omron Nj501 series. Everything is OK and the system works. But, If I change "output device 1" in "axis basic settings" to "<not Assigned>" then re-select again my Ezi driver it does not work and I get the same error message. I checked everything. There is no change in the axis settings.

  23. I have done some digging and cannot find an alternative.  I need a Multi-State Indicator for my NA-Series HMI that functions like the "Data Lamp".  I do not like the "Data Lamp" because of the darker shade to the color scheme.  Does anyone know of an alternative?  I know I can simply use several "Labels" of different text/color and then only make "visible" the state I want the operator to see...…. Thanks,
  24. Hi, I've been having a problem with my Schneider setup, and I can't seem to figure out the problem. I'm using Machine Expert Logic Builder and Vijeo 6.2, and I can't seem to download to my PLC. I can download to my HMI just fine, but my HMI comes back with the message as mentioned in the title. Also when I perform a full download, machine expert comes up with the message "Could not connect to the device for item "xx", selected target system "PLC name" is different from the connected device "HMI name". The weirdest thing is that machine expert shows my PLC just fine, but doesn't show my HMI. I have no idea what to do, as I feel like I've tried everything. The IP range is fine, subnet is fine. The driver in IO manager in Vijeo has the PLC nodename in it, so that shouldn't be the problem either. Does anyone know what to do in a situation like this? Thank you in advance!
