  1. ANALOGIC BIPOLAR OUTPUT - HELP

    Hello everyone,   I'm a student who recently started programming, and I could really use some help.  I have a CPU-31 CJ2M OMRON PLC and a ADO41-v1 analogic card. I need help programming an analogic scale with a bipolar signal -10V to +10V to then control a drive, which will then control the motor. If anyone could help me out of give me some examples I'd be really thankfull.   Thanks!
  2. Can't modify memory

    Hello, I don't have much experience with OMRON PLCs, but here we go. I am using CX-Programmer version 9.1 There is machine in my factory which is running on Omron PLC and HMI. Operator has an option on the HMI to save and load programs. Basically there are 150 lines in memory for each program (example D10000 - D10150), there are 16 different programs. Problem is that operator is saying that some of those programs are corrupted and she can't save new programs there correctly. So I thought I would try to delete some of the lines from the memory to see if that could fix the problem, but I do not know how to do it. When I open memory area in PLC and go to monitor mode and get the data for ex. D10000 - D10150 and I write 0 into every box and then try to upload it to PLC but I can't. I don't understand why is the "Transfer to PLC" button grey. What are the requirements for the button to go active? Or what would be the right action here if I want to clear the specific area in the memory? Any assistance regarding this problem will be much appreciated.
  3. 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
  4. 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   
  5. FX3u4AD reload issue

    I have an FX3u16MR attached to two FX3u4AD units (right mounted).  I am running the first two channels of the eight in 12 bit mode, the next two channels in 16 bit mode, the next two channels in 12 bit mode again and the last two channels are idling.  All inputs are configured as 4-20mA.  Working with the first channel only for now, what I am finding is that I have to load the gains twice for them to take.  It points to a timing issue in the code that I am running in the plc.   It just seems to have started happening though.  Admittedly I am recoding so the ADC calibrates from a HMI rather than from a PC trigger which is what I had before.  But I have just paralleled up the M register that invokes it.  I am working through the code as I speak. If anyone has any idea's i would love to hear from you.  I know this bit of kit fairly well I am just missing something here and it is bugging me.  A problem shared and all that. Thanks in advance.  
  6. 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
  7. 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   :)

  9. 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
  10. Getting to memory.

    I know enough Ladder logic to get in trouble. Although, I do have a few PLCs controlling machines that I wired and programmed and they are running well (as long as I can remember what those buttons I added do.) I cannot figure out how to get memory into the PLC.  For example, I have a Counter where I have entered the following: CNT 0005 W1 ( I am driving it with a 1s clock and the reset is an external button.)) I then went to working memory and entered a number as position 1 (I entered 234) When I load the program and press the button to reset, CNT is starting at 0. When I move the W memory from PLC to PC there is 0 at that position. All of the boxes are checked when I compile/transfer. Is my CNT format correct? How does one get the memory to the PLC?

  13. I READ IN THE MANUAL FOR THE CJ2M-CPU34 THAT IT IS POSSIBLE TO CHANGE THE IP ADDRESS BY WRITING TO D30098 AND D30099 (MY DEVICE IS UNIT 0).  I TRIED TO DO THIS ON A TEST PLC BUT AM NOT HAVING ANY LUCK... I WROTE MY IP ADDRESS #C0A8 TO D30098 AND #0E30 TO D30099 (IP ADDRESS 192.168.14.48) WITH THE CPU IN PROGRAM MODE, I SET THE RESET BIT (A501.00) TO TURN ON ON THE TRAILING EDGE OF THE FIRST SCAN BIT, I CAN TELL THE CARD RESETS BECAUSE I AM CONNECTED VIA ETHERNET AND I GET DISCONNECTED, BUT THE IP ADDRESS DOES NOT CHANGE.  IS THERE ANY WAY TO CHANGE THE IP ADDRESS WITHOUT CX-PROGRAMMER?  I NEED TO GET A SOLUTION TO MY CUSTOMER TONIGHT AND MY SUPERVISORS DO NOT WANT TO RELEASE OUR DEVELOPMENT CODE TO THE END USER.   THANK YOU!!!
  14. 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.
  15. 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

  19. RS Logix 500

    We have a PLC that controls a diverts for cartons.  The PLC talks to a host to get the divert code and then this is used to trigger diverts through device net.   The issue we are having started back a few months.   We are getting good scans and the information is being sent to the host and back, but cartons are not diverting 100% of the time.   If we remote connect to the PLC and have the program open, the issue goes away.  When we disconnect, it issues occur again.   The PLC has a wired connection through a network switch.   Is this a problem with the PLC or with the network switch or somewhere higher up in the connection?  If it is the switch, why does the issue disappear when we are connected?    We are remote connecting with a laptop and the connection we use is wireless.
  20. 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?

  23. Help Programming a Beckhoff PLC

    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!
