  1. Implementing the Omron CX Server DDE and Excel

    @Rahul_Punk_ I have fixed the link in Jay's post.
  2. Cycle Time and Accurate Positioning

    I would expect that this issue is mechanical in nature.  0.02 mm variance in a mechanical system is not that much unless you have specialized actuators.  If you observe the command and the feedback from the encoder using CX-Drive and the numbers are repeatable, then you have an issue with your actuators.
  3. Hello,

    can you check :  

    NX1P

    Started by Molvik, Friday at 7:55 PM

    Please.

    Thahks for link.

    We have two machines  main drive  AC motors: 7,5 KW and 15 KW.

    production line is made 1980 whit resolver for positionig and speed control.

    So, i need to control speed and position. Plan is to drive 3 phase AC motrors with VFD and use two encoder.

    On OMRON site i found https://www.myomron.com/index.php?action=kb&article=1490

    Now i looking for someting similar for NX1P2 because i have NX1P2 + EC0222 + E6C3-CVZ 5Gh (2x) encoder

    I think we need also pulse output unit to send  pulse train to the inputs of VFD.

    Output conveyor on firist machine and input conveyor on secod machine must running the same speed and positionig 

    how would product from first conveyor fell on providet for that positionig. The speed of conveyors is 1 - 2 potation per second.

    best regards.

  4. HI MICHAEL WALSH
    THIS IS HARSHAL PATEL. I AM NEW IN OMRON PLC PROGRAMMING. I WANT TO COMMUNICATE TWO OMRON PLC CP1L. BUT I CLOULD NOT OPEN SOCKET FROM A PLC. I HAVE ATTACHED MY PROGRAM WITH IT. CAN YOU LOOK INTO AND UPDATE ME WHAT CAN I DO FOR IT?

    THANK YOU

     

    THE ERROR IS COMMING FROM A567.14 IS REMAIN ON.

  6. OMRON NJ/NX PLC to PLC Over Internet

    @NootNoot @IO_Rack I have fixed the links in the other thread.
  7. plc-plc via internet

    @NootNoot I fixed the links in PMCR's post.
  8. Cant´t download program to NS8

    This has been resolved.  See third post in this thread.
  9. Kepware to Omron via Remote Server - No Comms

    Can you provide a picture of what you are trying to do?  Complete with IP addresses.  Please show the PLC, the router and the remote PC.  Perhaps help can be provided with that information.  Also include the node # on the switches on the front of the CJ2M.
  10. File Copy for NX/NJ

    The MOVE instruction now does indeed convert data types (only certain combinations where you don't lose resolution however).  
  11. Sysmac Studio Improvement Request

    The variable discussion made me think of this tip.  It does not address your online edit issue, but is useful for programming offline.  There is a setting that allows you to select whether a variable will be created as a global or a local variable when you add it in the ladder editor.  To do so, go to the Tools Pulldown menu and choose options.  Then check the box as shown below: Then the following dialog will shown when creating a variable as you add elements:  
  12. sample logic

    There really is not much logic to it.  The temperature shows up in a register for each of the 4 inputs: Input 1 is in word n+1 Input 2 is in word n+2 Input 3 is in word n+3 Input 4 is in word n+4 n = 2000 + 10 x unit number. So if the unit number dialed in on the front of the card is 3 and you are looking for the current value of input 2, then you would look in address 2032. Explaining - n = 2000 + 10 * 3  = 2030.  Input 2 is word n+2, 2030 + 2 = 2032. then you use that number for whatever purpose that you need.   Here is the manual:  https://www.fa.omron.com.cn/data_pdf/mnu/w368-e1-10_cs1w-p____cj1w-p___.pdf?id=1644 Look in section 3-3.
  13. Timer Countdown in Minutes and Seconds

    The TIM instruction is not in milliseconds, it is in 0.1s increments.  So, 6000 (BCD) = 600.0 s = 10 minutes. I cannot save the picture on here, so I will have to type it.  You can use any addresses that you want, but I chose these.  My timer is T0. P_On contact to do all of this: BIN T0 D0               Convert the present value of the timer to an integer / D0 &600 D2          Divide the integer by 600.  This gives you minutes remaining as a whole number. FLT D02 D4             Convert the integer to real. D4 has the value of minutes remaining as a real number.  Display it on the screen with no decimal places. FLT D0 D10             Convert the current value of the timer (0.1s value) into a real number. /F D10 +600.0 D12   Divide the value by 600 to convert to number of minutes as a real number, so 900 (integer) would convert to 1.5 minutes. -F D12 D4 D14        Subtract the whole number of minutes remaining from the real number of time remaining.  Given the 900 example, this would be 1.5 minus 1 = 0.5.  D14 has the fractional minute value remaining. *F D14 +60.0 D16    This converts the fractional minute value in D14 to seconds.  So, 0.5 * 60.0 = 30 s.  In this example, T0 would have a BCD 900 in it, D4 would be 1.0 (whole minutes) and D16 would be 30.0 (30 seconds).  Be sure to display the D4 value on the screen with 0 decimal places.  You could display D16 with one decimal place or 0, that is up to what you want to see on the screen.   There are other ways to do this, but this is one suggestion.
  14. From a DM: Hello Michael , I'm new here , i have doubt with the display of a timer , my boss request a count down display in the HMI but how we can display the real value? I mean i need to put  Countdown display of 5min but the TIM is in miliseconds 6000 = 5min and in the display only put 6000. i hope you can help me.  Regards. Ivan  @Ivan Fajardo
  15. Comm1 orange LED steady and communication problems

    If the orange COM1 light is on all the time with nothing connected, this sounds like you have a hardware issue with that port.  This is not too surprising considering that Omron has not sold C200HS PLCs in 20+ years (my guess).
