  1. Good day. I'm using 1756 L71S GuardLogix Integrated Safety Controller with Studio 5000 v28. My controller is connected to a third party software through ethernet connection, it simulates my project hardware and provides all the signals to my PLC. To know all the hardware signallocation at PLC memory, it uses a Tag export file provided by Studio 5000. In other PLCs, when you declare a variable as hardware input, you have to select in which address from the memory you want this input to be read, something like "Bit Input 0.0". But in AB this step is skipped, that is all addresses are managed by Studio5000 and hidden from the user. Is there any configuration at Studio 5000 that let me assign or at least see this addresses? Normally I would prefer my tags addresses to be hidden, but in this specific case it is more useful to know memory addresses.  
  2. Hallo.  Can someone shed some light on how much memory st takes ? does it use more that traditional ladder? i find that a routine with a couple of thousands of lines uses over 500kB is there any tricks to lower the usage? Or is it just what it is, and buy bigger cpu’s
  3. Hello people, I hope someone can help me with this. The system is connected with 8 PLC's. I want to transfer the data memory of a PLC to another like this: D850 from PLC2 to D900 PLC1 D850 from PLC3 to D901 PLC1 D850 from PLC4 to D902 PLC1 D850 from PLC5 to D903 PLC1 D850 from PLC6 to D904 PLC1 D850 from PLC7 to D905 PLC1 D850 from PLC8 to D906 PLC1 The data memory is an integer.
  4. Hello! I am using S7-1200 PLC 1212C AC/DC with configured Modbus TCP Server. I can already read/write Inputs/Outputs (Coils) and Memory Words. However I'd like to read/write Memory BITS. Is it possible? If so, how? What addresses should I use in TIA portal? And which function codes on client side? Thanks in advance!
  5. Compare data RS232

    Halo, my name is Riandanu, I connect PLC Omron CP1E to weighing scale, and its done. i think i dont have problem between PLC and weighing scale. And i want to ask about, how to compare value from weighing scale ?  example : from the picture you can see value of weighing scale is " ST,+00160.66  g", and i want to compare it with 180 or 150 to give output on to lamp. Thankyou Riandanu       PLC to ek-i.cxp
  6. Hello,  I got Allen-Bradley  1769-L36ERMS, AB Powerflex 755 and 20-750-S3 safety card.  According to: https://rockwellautomation.custhelp.com/app/answers/detail/a_id/946912 „"There is NO Integrated Motion / CIP Motion support with 20-750-S3 safety card” so I want to run hardwired emergency shutdown system.  How can I configure this module with safety card in PLC?
  7. Retain Memory CJ2m-CPU31

    Hi All, Just to verify if the "memory card" , in attached document Page 4 highlighted area ,  provides Omron CJ2M CPU21 to retain memory when powered off? If yes, for how long can the memory lasts without being charged? Isit capacitor or battery? Thanks in advance. Regards, Summer cj2m-cpu31.pdf
  8. We have Q06UDEHCPU PLC.   We require to attain 1k of file registers in standard Ram. Please find our settings attached - PLC Parameter.png; When we try to down the register file – we attain the following error; “Failed to access standard Ram” error message (attached - Downloading Error.png); The program is very small – and thus we have plenty of space as well.
  9. Mitsubishi GX Works Bugs??

    Hello I have been using GX Works 3 for a while now and I have discovered a couple of things, maybe bugs. I have not had any training for the software or hardware so maybe I did something wrong. 1 Labels. If you sort a global label table into any order other than the unsorted order that appears by default you are unable to create, delete or edit any labels. Our Mitsubishi representative discovered that if you click on the column header between 'Data Type' and 'Class' the order does not change but now editing is available. This, it turns out is a really bad idea. It seems the position the label was in when it was created is preserved, I think this is the unsorted order you get by default. If you sort the list and then delete a label it is possible that the label that should be in that position is also deleted. I have attached a small project to demonstrate this. Open the Global Labels notice the order they were created. Now change the sort order, click on the column header I described earlier to make them editable and then delete the label in position 1. For a while I thought this was the only problem but recently there has been a number of instances where I have created a label, given it a carefully selected address only to discover that it is being overwritten by another variable. I have not been able to work out exactly what is going on but I believe it is connected to the sort order of the labels. Also if you sort the order and change an address, have you changed the address of another label? The only solution I have found is to keep label tables very short so they are managable without having to sort the order, that is probably good practice anyway 1 Axis software limits. I have been using a number of axes in pairs, in incremental mode as caterpillar feeders, using FX5U-40SSC simple motion modules. I had a problem that the axis synchronised to follow would suddenly stop moving, the customer was having to power down the machine and start again. This problem persisted for months with Mitsubishi scratching their heads unable to fathom it out and ultimately stating that the problem must be in my code somewhere. It was suggested by the customer that it may be getting to a software limit, I showed the customer that the software limit was disabled in the setup and it was confirmed by Mitsubishi that it was not the problem. guess what, it is a problem. Once the actual position reached the limit of the double word memory it would stop moving. The solution is the take the servos out of synchronisation in order to set the position (datum) to zero every cycle. Unfortunately the drives do not always re-synch on the first attempt so you have to keep trying till it does, this now causes slight variations in cycle times but it works. Andy EDIT: I have since been informed that to disable the software limits they must be set to zero. This implies that the Enable/Disable setting is invalid and the limits are defaulted to their respective max values. Surely a default to zero would be more appropriate.     Label Test.gx3
  10. I want some recommendations for a PLC that can hold its memory for long periods of time with no power. I have a customer that has the molds that only get used a couple of times a year and when they are not being used they sit in storage until they need them again. Currently they have a DirectLogic05 controller and what they have noticed is that when they pull these molds out of storage to use them, the program is lost and they got to download it again. They want to make it to were all they gotta do is plug and play basically for this machine. Is there a special module or a processor that can hold its program for long periods of time while it has no power on it? 
  11. Hi this might be stupid question, but I'm trying to use these functions for recipes: SaveAllRecipes(GetSelectedRecipeTemplate("myPage","myRecipe") System.IO.File.Copy(SAVEDRECIPEPATH?, SDCARDPATH?) Where does this save file go, which path I got to copy to use on my SD card? Then also to import recipe want to: ImportRecipes(myRecipe.SelectedTemplate, SDCARDPATH? & myRecipe.SelectedTemplate & ".csv") Also mention that there's no computer connected to the controller. When I was doing my simulations I could see that SaveAllRecipes generated csv file that went to "C:\OMRON\Data\Temp" folder. But there's no computer to store the saved recipe in this case. Thx in advance
  12. 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.
  13. mitsubhishi serial drivers

    Hello write now i am working with Q6UDEH PLC  project in which (nextgen 2000) 6021 card is used for conversion of serial to Ethernet data & vice versa , is it possible  by only installing the Mitsubishi serial drivers ?? or can anybody tell me how these Mitsubishi serial drivers works ??

  15. 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.  
  16. 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?    
  17. Upload file using CF card

    Hello all I have a folding machine with Omron PLC and HMI NS5-SQ10B-ECV2, the problem is the hmi software disappeared and " No project data" appeared. I contacted the manufacturer and they sent me A single Ipp file. i am not really experienced in omron but i knew that i can upload the soft using CF card so, i used it and switch DIP6 , and the HMI recognized the CF card put it did't see any software. i tried to put the soft in folder with the same name but with no luck. I attached the file he sent me. 出口.IPP
  18. 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!!!

The information required includes; [1] Purpose of macrocode (incl advantages) [2] its utilization's effects on the PLC programming memory (it appears that it consumes more programming memory. [3] any reference documentation that could be used - containing specifically information regarding this feature (note most manuals doesn't discuss this)
  20. 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.
  21. Help to find out specification of analog card AD-081-V1 . please suggest me this analog input card is active or passive?.
  22. Hello, I'm trying to use Mitsubishi GX Works 3 version 1 for the first time and get a 'memory is insufficient' error window when I try to open/start a new project or if I try to open a PLC project a co-worker made. I am using Windows 10/64-bit, company we purchased the software from says they are using it on windows 10 without issue. I get the error with no other programs running, have 6 GB RAM, and have 90% hard drive space available. I have monitored Task Manager while opening a file, RAM usage seems fine, and have tried opening with "Run as storminess".  I have tried uninstalling the program using the window "uninstall or change a program" - is the a different way to uninstall this program that will wipe it more completely? The install CD has Disk1, Disk2, Disk3(DocFX) sub folder , Support folders - I ran the .exe file from all 3. Does anyone have any suggestions? I am able to open an HMI project in GT works 3 without issue. I attached a screen shot of the error. Thanks so much!!
  23. Hi..  Looking for a reliable SD card that will work well in the NA5 HMI..  I can't afford the Omron SD card.  And, if there's one out there that will work in the $50 or less price range, please let me know... Thanks, Regards, Michael
  24. Hello, My quest is to make a memory card, which I can just put into my PLC on the field and load all program and options etc to my plc. Now i found the official omron guide about it but its not good at all... For example is does not explain that how i need to transfer the H and D memory part to the plc, and that not all network settings are being copied if im not careful.   But my question is: is it possible to make this backup memory card without having the actual plc? Because the process is done in memory card window, which is only available if you are online. So basicly i have to get all the plc rack parts to make this work? I tried with the simulator but ofc it is not working.   Someone mentioned me that it is possible he heard from someone but no one actually knows how to. And there is nothing in the omron manual as i see.
