  1. Hi All, I am doing an application that use servo motor to feed plastic film to a target length (set by operator), and it need to stop immediately if marker sensor is ON. This application is control by Omron CP1E PLC. It will feed plastic film in 500-1000mm/s depends on the target length set by operator. It is require to stop immediately if the servo feed length more than 90% of the target length and the marker sensor is ON. However, is there any possibility for the servo to stop immediately once the condition is meet? As I am using PLS2(887) to feed with target length, and INI(880) to stop immediately, however, it cannot get the desired result as servo not able to stop immediately after marker sensor is ON, I am not sure is because of the PLC scan time, or servo need time to deceleration (deceleration rate assigned to #FFFF). Appreciate anyone able to assist on this. Thank you.
  2. Hello I have a scenario that's been bugging me for some time now. The scenario consists of a Micrologix 1400 that I need to control it's output from modbus/tcp. In detail what I really need is to be able to manipulate the O0:0 through modbus/tcp. The PLC would be the master and I would be the slave that triggers the connection to the master. I'm using a Modbus-Client on my PC and that should be the slave. Any idea as to how I can manage that? Currently I can send data to the master but everything is "stored" on B10 and I have no idea how I could write directly on O0. Thanks a bunch guys. PS: I'm borderline noob. 
  3.  Hi all. I have a question about how to set up the motor in rotary mode. My application will be a basic rotary table driven by a servo motor without gearbox between. So, in my servo drive axis settings, I select the motor as a rotary mode. then I defined the maximum position setting value for 360 degrees, and minimum to 0. So far so good. But the problem comes when I want to make an absolute move using the mc_moveAbsolute to move 360 degrees. Whit this settings the error "target position settings out of range " will come up. So, what is the solution to rotate 360 degrees without generating this error? if I set up the maximum value to 361 degrees and then if I rotate 360 the error will not occur and the motor will rotate 360 degrees as I aspected, but it's this correct ? or there is another way to do it? Thanks  
  4. C-mode hostlink library for NJ/NX1P or CP1L

    Anyone knows if there is a C-mode hostlink library for NJ/NX ? Also, a C-mode hostlink library for CP1L could be helpful, to translate such a library to work with NX1P is probaly less work whan writing a new library.  Maybe Omron France has developed such a library? - they seem very active..   Background: Looking into writing a programmatic c-mode hostlink master for NX1P12, this is for connecting the handheld NSH5 HMI to the NX1P12 via RS232C using a CIF01. I have the hardware set up, and an machine built, expected some compatibility efforts by Omron.... but the NSH5 seems to talk C-mode hostlink, and the CIF01 only seems to support the FINS version hostlink.   On the NJ you can of course add an SCU module, thus not need a library.  But working with NX1 ( due to limited space available ), you are dependet on available CIF-modules which do not support C-mode hostlink.

  7. Here is a link to a thread on a recent post showing how to communicate serially to an Omron PLC using VB.Net. This uses the Omron Host Link serial protocols. (C-Mode Commands) It will read 10 DM registers and display them on the form.   http://accautomation.ca/implementing-the-omron-host-link-protocol-vb-net/ Here is the source program that can be downloaded.

  8. Hi, I have some trouble with a CJ2M-CPU33. My client did a backup to memory card earlier today, and after this we did some changes through remote link. Now the client wanted to restore the previous backup to the PLC and has done so, but the system would not function correctly. After going online on the PLC it seems like the PLC is stuck in "Stop/Programming Mode". When trying to change to "Monitor" or "Run" mode a dialog comes up containing the following message: "Failed to change the operating mode. The operating mode may be still changing in the PLC."  - All the dip switches are set to off after restoring backup - The PLC has been rebooted  - I have downloaded the application again through CX-programmer  - Verified that the PLC is set to start up in "Monitor mode" But nothing helps. The same message comes up when trying to change the operating mode.  Hoping anyone can help to resolve this issue as it is very critical for us and the client. In advance, thanks for any tips or help received. Best regards Stian

If anyone could help me out of give me some examples I'd be really thankfull.   Thanks!
  11. PLC Training

    Hi Everyone We are setting up a initial training in PLC programming for technicians, I got some experience with SIEMENS S7 but this seems to be an expensive choice, we would like to opt for a budget PLC but at the same time would like a user friendly software for teaching......I would like to have views of users of other PLC brands such as OMRON, MITSUBISHI or even Schneider??? thanks Jay
  12. Micrologix 1400 Float TAG

    Hello,  I have a micrologix 1400 plc connected to a length measurement gauge. The gauge sends an analog value to the plc to an analog input. I convert the value into a dimension and send it to F8:0. but I need this value in three different steps in the program. Since i just have one element of float (F8:0) is there anyway i can store the value in a different location or create more floating point tags eg. F8:1. F8:2 ?    Thank You   
  13. I’m using a Omron NJ to manage a LinMot linear motor .. all is going very well; however, there have been a few times during this development phase when the actuator, or programming creates a fault, perhaps from a following error, or exceeding a limit.  The result is sometimes scary.  The actuator might accelerate into a hard stop.  Not a big deal, the ends are protected with Sorbothane, so it isn’t a big problem .. yet.  Once the system is correctly programmed, it shouldn’t ever accelerate an actuator into the hard stops. In spite of my newbie-ness  to Omron programming I’m aware of the need to employ error & fault action that will stop a run-away actuator in closed-loop control, rather quickly. Just how to do that.. has evaded my research. I’ve noticed:  “FaultHandler”  in the W507 & W508 Manuals. And, been quite frustrated to not find any reference to FaultHandler or FaultHandeler()  .. which kinda suggests it’s a program?… and also expected to get some clues in the "NJ Programming Best Practices V1.1”   so far… no luck. Perhaps I’m going about this all wrong..  The LinMot Driver Controller might be the way to go.. An error message from the NJ to the LinMot drive would quickly shut down movement in closed loop .. instead of turning the motor into a rail gun… Any suggestions at how to do it with the NJ,  would be greatly appreciated.. Thanks Regards, Michael PS: here’s the progress so far, thanks to many out there, and on this forum ... https://www.youtube.com/embed/B0UGm9JTw3U?rel=0  
  14. I have recently come across a free virtual plc simulator called PLC Fiddle. It will enable you to create simple PLC ladder logic code within your browser. This is an ideal way in understanding PLC concepts for industrial automation. All of the basic PLC instructions that come with most plc units have been incorporated in this virtual PLC software.PLC Fiddle is currently in an early stage of development but is functional enough to be helpful to you in learning and understanding PLC concepts.  http://accautomation.ca/plc-fiddle-online-editor-and-simulator-in-your-browser/ YouTube Video: https://youtu.be/G43ZLOwu2dM www.plcfiddle.com Let me know what you think of this for a learning tool. Thanks, Garry
  15. Hello Friends,  I've been writing a program for several days now, Actually I'm an immature for CX programmer and also for plc programming, So I'd like to ask you, if there is any decent way ,,,,I mean a good method of starting to write a program and keeping the flow of it so, it is easy to keep track on what i've been doing from the beginning.??  Cuz sometimes I face the problem of loosing points that were written by myself but not remembering them, So I'd like to learn how to organize my written lines as a wanna be professional.   Thank you   :) 
  16. Urgent help CS1 CPU Stop

    Hello all, Require some urgent help on a project, apologies if poor explanation.... When CS1 CPU goes into stop mode in fault condition, eg fatal cycle time error, outputs retain in the state they were when CPU was stopped. In code we monitor CPU status and turn output high to pull in relay to indicate CPU status normal to wiring circuit. But if CPU goes into stop mode relay remains energise as code is not running to turn output off?? Therfore for examples conveyors keep running... How can we prevent this, can outputs be configured to go low if cpu stops? Any other ideas? Any help will be appreciate, thanks.
  17. Programming cables

    Is there any website that provide all details about programming cables for all PLCs.  I have one local Indian plc "Genie NX" manufactured by GIC India. I want to make programming cable for same. but unable to get details. please let me know if anybody used it? http://gicindia.com/index.html for more info
  18. Hello,  As the title indicates, we have a micrologix 1400 that has been installed for a long time.  Recently it faulted out on 71h and was in Remote Mode.  Do these PLCs revert to Remote Mode when in a fault condition?  We placed it back in Run Mode and everything worked fine, but how did it get to Remote Mode in the first place? Thanks,  J 
  19. Hi,   I am using Omron CP1E NA 20DTD with built-in ANALOG inputs and output. I know how to deal with digital inputs. But I have no idea about analogue input wiring and programming. I tried connecting gefran LVDT PY2 directly to an analogue input of plc. But the indicator light did not turn on. Do I need to use any signal conditioner or converter? The output of lvdt is 0 to 25volts. I HAVE ATTACHED THE DATASHEET OF LVDT. DTS_PY2_06-2016_ENG.pdf
  20. For some background information, I am in the process of converting a Mitsubishi FX2N to a Siemens S7-1200. I am viewing the Mitsubishi program with GX Developer Version 8.116W. There is this subroutine in the Mitsubishi program that appears like it will never run. I think the purpose of this subroutine is to clear the status of the devices in the PLC. I have attached a picture that demonstrates what I am dealing with. Can anyone tell if the subroutine P7 will run at any point? Thanks! For those who are not used to the Mitsubishi world or want to brush up on their Mitsubishi knowledge, below is some information regarding the devices and functions used in my example: M8000 - Always on bit (turns on when PLC is running and turns off when PLC is stopped). M500 - Just some random memory bit I chose. FEND - Indicates end of main routine program (everything below this rung is either a subroutine or interrupt routine, so it will only be processed if called from somewhere). P7 on left side of power rail - This is a label that indicates the beginning of the subroutine called P7. M8031 and M8032 - Special memory bits that, when set, tells the PLC to clear certain devices. SRET - Indicates end of subroutine.

  23. Hello All, A little bit about my current role. I am currently a Automation and Welding Robotics Programmer ( automotive industry ). I have been programming robotics for almost 4 years at my company, but this is all experience work, no qualifications. I enjoy the role but this is very insecure due to having no qualifications, if the company was to go under. I am currently working out in Hungary on a secondment with my company. The project was the introduction of a second line at one of our other plants. This has gone successfully and will be coming to an end come December.  While i have been here i have been working with a PLC Engineer ( Contractor ), After speaking with him about his role it intrigued me and felt it was something i would enjoy pursuing. Unfortunately it appears that he is a "knowledge is power" kinda guy which leaves me unable to learn anything from him.  So i am 30 Years of age this year... So my question is too any of you experienced and hopefully helpful individuals is...  Is 30 too old to start this career? if not then; Where is the best place to start learning about PLC Programming? What should i be learning? What courses are available? - Are there recognised governing bodies for this role? What career path would you suggest? I hope someone is willing to share info / answer some of my questions. Help in anyway would be greatly appreciated.
  24. Hello, I am currently working on programming my first sortation system.  Attached is a blue print of the in feed conveyors and their loadout lines.  As boxes merge together they will be scanned by the barcode scanner.  From there we will be told which lane each box must go down, from the WCS.   My question is, without encoders, what would be the best way to control this system? Counting the packages as they pass through the photoeye? Or setting timers?   Thanks, James Sorting Conveyor Layout.pdf
  25. Binary Mode vs BCD Mode

    Hi all, I have created a program using the binary counter and timer instructions and everything works fine (yay!), but I am not entirely sure if there is a major difference between using Binary mode or BCD Mode on the PLC. Does it just come down to personal preference or is there an advantage to using a particular mode over the other? Also, does the operating mode affect anything besides counter/timer? The option in CX-Programmer seems to indicate it doesn't. Cheers, Jay
