  1. Hi,  I'm new to TwinCAT 2 and i'm upgrading a long time design (hence the TwinCAT 2 reference), to read a more sensitive torque signal.  I'm using a Beckhoff CX1030 as my PLC Controller.  I needed to add 'homing' to my motor sequence and confirmed with Maxon, im using the function blocks correctly and in the correct sequence to establish my 'absolute zero'/'home' position.  The motor has an output to write to:  ControlWord, which tells the motor that the position it is sitting in is '0.'  My program compiles, it runs, it writes each function block, but it's not seeming to get back to the test run opMode, even though i tell it to and the function block performs the 'Write' function.  it's stuck at zero and not reading an analog input signal from my torque sensor.  so im getting an artificial torque reading through every test.   i think this is related to my tare motion.  I start the program, home the motor, get into profile velocity mode, tare my sensor, enter profile position mode, go back to position 0, then back to profile velocity mode, run a test, sample data, go back to 'home' or '0.'  I wonder 1st, is my variable not linked properly through the system manager?  2nd, i set a boolean variable to set the 4th bit to 1 in my control word write (setting the 4th bit high will set my current position to absolute zero), but did i not connect the program to the main sequence properly?  looking to read a valid signal again and see that my motor moves back to 'home' each time.  Do i not need to home the motor after the tare, since the tare nulls out the torque value after the tare? after this i need to program my sample period, instead of it being fixed, as it is currently written and then use my home position as my trigger to start sampling.... Beckhoff applications department is overloaded, currently and can't help and this is all beyond the knowledge of the general support line.  I've gotten fairly far, on my own, but of course, the project is under a time crunch.   Does anyone know twincat well enough to help guide me?

  2. PLC Training

    Jay T posted a topic in Product Reviews

    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
  3. 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   
  4. 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
  5. 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   :)

  7. 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

  11. 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.
  12. 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

  17. 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?

  20. 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!

Thank you, Romica
  23. Hi! I just started with PLC programming. I am trying to get the time between a output signal and a input signal. The problem is that the time is ~200 ms but when i measure it with this code:   TONR(Timer1); IF PosFeedback <= PosFeedback_Min & not Timer1.Reset THEN Timer1.TimerEnable := 0; FullCloseDeltaTime[1] := Timer1.ACC; Timer1.Reset := 1; END_IF; IF (move & not Move_LastScan) THEN //Start timer Timer1.TimerEnable := 1; Timer1.Reset := 0; END_IF; Move_LastScan := move; i only get even values in intervalls of 50 ms like 150, 200 and 250 ms. I have changed the real time sample rate to 11 ms so i don't understand why i don't get a more exact result. And i can see in my trend that the time isn't exactly 150, 200 or 250 each time. I i tried and time my own click on a button and i see the problem is the timer, i only get values in an interval of 50 ms. Is there a way to make the timer more exact?

  25. 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.
