  1. Hello everyone, I have a problem with packing machine. There are some issues with one of the axis, when axis actual position is near to 1800000 some error appear and operator has to turn off machine on main contactor. This axis is working in Linear mode. I think that rotary mode would be better for this axis. And here is my question. Which instructions, and what options i should change/check when i change count mode in axis's options. Can any1 point me some manuals to read or give me some advice ? Thank you in advance.

  4. PLC occasionally going out of Run mode?

    Has anyone had an issue with Siemens plc's occasionally going out of run mode? I was doing some research and found that it could be due to a bad analog input. Is there a way to tell which input or output is causing this fault? I know I can create a hardware diagnostics error organization block but that only correct from what I've read.     Edit: I've added a screen shot of the diagnostics report. The fault that may be the problem is: Temporary CPU error: Serious firmware exception  CPU changes to DEFECTIVE mode (system reaction)  This plc / system was installed 2 year ago and we've had this problem occasionally since. I'm guessing the wrong firmware was used during the install. Will try upgrading firmware this weekend.

    Hello friends, I have been working on Granite Line polisher machine. I have completed the program but there is a requirement for polishing the Uneven shape of granite slab. Has anyone worked on logic of this machine? Can anyone give some idea for the logic or the Plc program. I have seen Chinese machine manufacturers giving this feature. 
  6. BECKHOFF CX-9020

    Hello PLC experts, I am master student currently writing thesis. For this, I have a initial task of making some changes to PLC program (Just started getting to know about PLCs- complete beginner). I have a BECKHOFF cx 9020 PLC connected to my notebook using ethernet. I am using TWINCAT 3.1 (VS) as IDE. Firstly, I cannot find my PLC IP address connected to my notebook . I added the route in the Twincat and it shows the PLC is connected. When, I am trying to run a program (activate boot project), I am unable to login to the PLC. It gives an error "login failed for application port 851". What I undertood from BECKHOFF scripts,  there is something wrong with the ADS ams net ID which I am trying to figure it out. I appreciate all the help. Thank you.

  9. Hello folks,   I am a rookie, self-training in PLC programming. I have written an SFC exercise (attached ACD file). I also try to call STL written subroutines and add-on instructions, from within the SFC main program. Calling the created subroutine works fine, but calling the add-on instruction fails from a reason which is above my level. I tried, tried and tried different solutions, with no avail. I am either wrong in writing the add-on (perhaps some missing but missing tag ?), or wrong is calling it. Can someone please give me a hint on what I do wrong ?   Thank you, Radu PS . I use Studio 5000 v24, combined with RSLogix 5000 Emulator.     SFC_trial.ACD

  12. Panasonic FP0 C14RS

    Hi All, I am new to the forum and new to programming PLC and like every newbie I have a lot of questions - Brief History of me - I had been a Manufacturing Technician for 20 years and recently got my BS on Electrical Engineering and now working as an Equipment Engineer. The main reason that got me interested in PLC's is my degree,  the field that I would like to get into and a recent problem that arise at work. My experience with PLC is very small in programming, some in TS I/O- However I had been studying by my self to the point that I built a test bench to understand it better and in the future create different project for learning purposes Currently I am putting together a tool Alarm delay program - Basically my exhaust sensors trigger an alarm (input signal turns OFF) before its send  the signal to my tool for abort, I want to create a different Alarm which will cause a different response from my tool and delay the original Alarm by 10 min and then trigger the original Alarm - PLC = Panasonic FP0C14RS  Reasons: Create a different Alarm: The response from my tool to this alarm will allow me to return my material back from the tool and put it in a safe spot. Delay the Alarm: Use a timer to perform this tasks - This the time that approx. it takes the to return the material. Trigger the original Alarm: I need to know which sensor was the problem in order to properly TS- So after my timer is complete - I want to know which sensor created the original Alarm My Current problem: I created the LD program, and while the original alarm stays OFF the program works fine - but since my exhaust sensor are always on - If my original alarm is trigger for  a few seconds, just enough to start my Delay Alarm: I dont have a way to know which sensor trigger after my Delay(Timer)is complete,  I reset my relays in order to be ready for new alarm.   Please provide feedback to my program - I know currently is not the best way or efficient way to do this and there are better ways, but my plan is to get it to work and then later revisions improve the way the program can be written   Thanks in advanced for your feedback and help Exh_delay_inv_rev1.pro

  14. Hello.. I have hmi Proface GP-4301TW, USB type B cable and ethernet cable. I want to transfer the program to the hmi but I cant. When I turn on the power of hmi,  a series of test appears and finally it looks like the photo below and I cant enter the offline menu.. can anybody help me to solve the problem?
  15.  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  
  16. 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.

  18. Hi, In conception phase we currently use GXWorks to upload programs to PLC (L-Series). In production mode, for different security reasons we would like to automate this transfer so that the operator does not access directly to the program. Do you know any tool allowing this by using command lines and not GXWorks UI ? (GXWorks does not seem to be "command line" friendly As a POC I  have automated the GXWorks UI in C#  (by simulating menu or buttons clicks) but I don't find it reliable (what if an unexpected popup "pops" ? ). PS : I am a totally noob in this PLC world so maybe I missed stg in the docs ... 
  19. A machine was bought at auction which included PLC-5/15 module.  It did not come with a backup of the program.  Our maintenance technician said the program would not load and turned the module over to me (IT).  I notice the battery was installed in '92 so am assuming the program is lost.  Is their any internal memory or last ditch effort i can attempt to recover the program from this module?
  20. Hi Guys! You can read my problem below, if anybody can help, please do it. Thank you. So, I have 4 knife. You can set the cutting width for each knife separately. The problem is, there is a lot of size. There is an example: No1 size:  #1: 20 mm, #2: 25mm, #3: 30mm, #4: 25mm   (#1=Knife1.......)                                       No2 size: #1: 22mm, #2:24mm, #3: 32mm, #4: 27mm What is make the problem more difficult is There are plenty of type code too. Like X1, X2, X3, Y1, Y2, Y3 ..... This is the main material code. and you can choose the belogging size. So you can select for X1 to No1 or No2 ... but you can select for X2 to No1 or No2 or any sizegroup you want. I can solve it with a lot programming, like deal every possible situation ... but there is a lot time .... :S  There is a touch panel where you can set the values.  Anybody have another idea for this problem ?    
  21. 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.

  22. 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
  23. We have a QSeries PLC. Q25HCPU. We also have a PLC program. We found that the address registers (also known as device addresses) attain a z-value added next to it - automatically over time. We are not sure why this is the case. Nonetheless, when these values get added (by the PLC - not the engineering software), some of the functions in the PLC doesn't work. We found that by formatting the CPU, and reloading the program, allows for the system to work again (temporarily) for a few weeks, up until this problem occurs again. This problem occurs across various CPUs (eliminating the potential for hardware problems. These z values can be seen when a program comparison is done. (see attached file). The questions become; 1. What is the function of these values? (why does the PLC add them? 2. How can they be permanently removed?
