  1. 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.

  4. 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.
  5. 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

  6. Binary Mode vs BCD Mode

    JaySharp90 posted a topic in CX-Programmer

    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

  11. FR-DU04 (FR-A500) vs FR-DU04-1 (FR-V500). Programming unit differences. (A VSD question) What is the difference between these units? Why are they not interchangeable. (Other than the fact that the FR-DU04-1 is used for vector VSD applications, and the FR-DU04 is intended for standard induction motor applications. Is this a matter of firmware differences?
  12. Dear Friends; Good day. First i install the windows  virtual xp mode on Windows 7 64 bit. After installation i installed the FTM, RSLINK,and rslogix 5.0 in virtual xp mode.  Then i activate the software by Factory talk manager and select the hard disk and for a single computer activation. This process successfully acomplished. But when i open the RSLOGIX it shows popup that activation path is not found. Then i again open the factory talk tool and note that there is no activation shows in current activate products, But the activation detail shows in the RE host tab. I re hosted the activation by using go to Rockwell site and message show successfully activation re hosted.   *** Now i am stuck here is i loss my activation?  *** in windows xp virtual mode how i activate my product that application find the correct path of activation file? ** In windows xp mode if i open my Computer there is shows other hard drive partition as well as Local disk C:\  and activation file save in virtual drive instead of real C drive in windows 7. But there is no file path option to save the activation. Its by default save on C:\documents and setting\all user\shared documents\rockwell\activation\*****   Please help me how i activate my product in windows XP mode successfully?  Thanking you. i will remain Regards

  15. Help Programming a Beckhoff PLC

    jnatzic posted a topic in Other PLCs

    I have a very simple problem that I need help with.  I have some programming experience but I am brand new to PLCs and structured text.  I am using TwinCat 3 to program a Beckhoff CX9020.  My goal is to read the temperature from my thermocouple and open or close a valve based on the temperature.  I have successfully connected the PLC to the TwinCat software and I am able to see the value of the thermocouple increase and decrease when I touch it with my fingers.  I need to link that value to a variable in my code so I can have the valve act on it.  I don't know how to properly address the inputs and outputs.  Thank you!

  16. IPC 620-1536

    sashaleiz posted a topic in Other PLCs

    HI, there. I am new to the Honeywell PLC, usually dealing with AB or Omron. Need some help from the Honeywell PLC gurus, my the only one PLC IPC620-1536 , suddenly stop working. No "Run" light or any outputs are present. Turning the "Mode Key" to the "program mode" and back to the "run mode" doesn't make any difference. I attached couple photo. My question, is any other way to start PLC running again? If I purchase the Win.Loader and communication cable and connect to the PLC, can I change PLC back to "Run" mode and upload the program, or fail to change the Mode using the Key. means the same fail using the software? Please update. Thanks for advance,

  22. Hi, I am a beginner to PLC. I am currently working on a home project with Allen Bradley 1100 model. The project is to build a door open-shut cycle tester.  The motor I have purchased is a Bodine Brushless DC34B/FV INTEGRAmotor. My goal is to utilize the Allen Bradley to to control the motor and then the motor drive a shaft to open/shut the door. Through the LCD screen the of PLC, we can set and view the amount of cycles.  I have finished the initial stage of wiring. But not sure how should I start on the programming part. Could any of you give me any hints on the programming portion? Thank you so much.

  24. hey!  I'm pretty new to PLC's, and I'm supposed to ''teach'' the people at my internship how this PLC works, but I have encountered a problem.  I've gotten pretty far with all the digital programming and understanding how everything works, but I just can't figure out how the analog inputs/outputs and programming works...... I've had a fair explaination on PID and how this works. I've searched the web as well to figure out what PLC instructions to use.    I hope you can answer my following questions.    1, what are the most used PLC instruction blocks which I can use for temperature control, and how am I supposed to use them? 2, Could you please give me an example on how to use PID and what numbers will I need for the calculations? 3, what are the most used PLC Instruction blocks (apart form the analog ones) that I should include in my tutorial?   this is my setup: Ethernet switch MOXA EDS-205 Plc voeding PA202 PLC CPU CJ1MCPU11-ETN Digital IN (16x) CJ1W-ID211 (SL) Digital IN (16x) CJ1W-ID211 (SL) Analog IN (8x) CJ1W-AD081 (SL) Analog IN (8x) CJ1W-AD081 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) Analog OUT (4x) CJ1W-DA041 (SL)   thank you soo much for looking at my question and considering helping me! the OMRON helpdesk hasn't been very helpfull.    kind regards,    Deuslupos,
