  1. Getting to memory.

    graemeian posted a topic in CX-Programmer

    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?    

  2. Upload file using CF card

    M_M posted a topic in Omron

    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
  3. 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!!!
  4. Good day Please assist me - pertaining to the QSeries GXWorks2 Programming  - and in particular the utilization of the macrocode functionality. 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)

  5. RS Logix 500

    Steve Nelson posted a topic in Allen Bradley / Rockwell Automation

    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.
  6. Help to find out specification of analog card AD-081-V1 . please suggest me this analog input card is active or passive?.
  7. 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
  8. 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.
  9. I have L61 with nonvolatile memory installed. The controller will read the program from CF card on power up. The issue is that some variables are lost or not the most up to date values are read from the card since it remembers them as they were last stored on the CF card. So stuff like motor run hours, etc is not up to date. Is there any way I can update these variables or tags on the CF card as they are updated by the process? Or what would be proper way to deal with this issue?
  10. I have read that it is possible, in CXDesigner, to download the program from the computer onto a memory card, and then download from the memory card into the HMI terminal. Is a similar thing possible with CXProgrammer, and PLCs? It would be quite useful, for the purposes of updating the program on a customer PLC that is located overseas, when the customer does not own a laptop with CXProgrammer installed.

  11. siemens 1212C PLC

    Frans van Enschot posted a topic in Siemens

    All, I have bought a new siemens PLC 1212C. connected to TIA V13 software working perfect. When i use the clock memory byte, and selecting the 1sec bit M255.5 it is not counting. Why this is not working? What do i wrong? grtz Frans  
  12. Is SOE card compatible with both quantum & premium plcs.? 
  13. I'm using the connected component workbench software and the Micro830 plc is there a way I can tell how much memory is left? I have done some programming on the Micro830 and with just a few rungs and variables it is already reporting out of memory.

  14. OMRON CJ1M CPU 21

    ibraba posted a topic in Omron

    Hello to all Since a certain time I've noticed that the parameters values sent to the plc via IHM are not anymore recognized by the plc I'm obliged to re-enter other parameter values to see the machine working fine again. The plc reference is: CJ1M CP 21 The IHM reference is NS10 What would be the problem,? Best regards.
  15. Hi all, Currently running a Quantum 140-CPU-652-60 FW3.12 out to a remote rack over a Modbus Drop in to a 140-EHC-105-00 High Speed Counter, words are mapped OK to the program, configured at a type 7 setup (1sec frequency) etc. The card used to work when we were running the system as a ConceptXL 2.6 setup with a 140-CPU-534-14. We have just upgraded to UnityProXLv8 and it stopped. The mapping is configured by word to bit / bit to word across the %IW and %MW (previously 948 3x and 4x registers, but converted nicely, everything is aligning). Anyone stumbled across this issue before? Any help would be appreciated. Thanks, Rob
  16. I am trying to determine or find any figures that could assist in obtaining the lifespan of a single output of a 1756-OB16E output card. I have a signal sending 400 pulses a minute to an output. I am starting think about when this card or output may need to be replaced before failure. I was given a MTBF range by Rockwell for the card itself but they could not expand on the likelyhood of the output failing exponentially due to the rapid signalling. I could also not find anything in the manual itself that could provide me with an idea of longevity, I could be missing it? Also with this project I experienced something odd with the originally scoped hardware, a solid state 24VDC relay (700-HLS1.) By measuring the resistance I was able to see that the relay should have been opening and closing but the signal was not being received. So, I swapped the solid state relay for a mechanical relay and it worked fine. I was curious if the leakage could have an effect on this. The problem with the mechanical relay is that the life is dramatically reduced to about a month for this installation, life for the relay is shown at about 10,000,000 actuations. I was hoping to have this working with a little longer life expectancy. If anyone has any experience / tips / or suggestions it would be much appreciated! PG
  17. I am trying to find a way to do a "batch monitor of Global Labels" in Mitsubishi GX Works2 Software. I can monitor Device/Buffer Memory Batch but can't find a way to monitor all Global Label's status online? Can anybody help me on this?

  18. Non-volatile memory GX Works2

    williamj posted a topic in Mitsubishi

    Hi all, Im trying to figure out how to create non-volatile memory tags in GX Works 2 (using a FX3U controller), so that the values stored in the D registers won't keep zeroing out every time the controller powers down. Does anyone have any helpful tips on how this is done? Thanks
  19. Hi there, I have trouble understanding the "mechanics" of STL programming language for Siemens S7-300 PLC. For instance I have a code which looks like this (taken from the Siemens manual for extended pulse timer): With regards to the first line, AND operator checks whether the state of I 2.0 is '1'. According to the "Bit Logic Instructions" manual, it also ANDs the test result with RLO. Now the question is - what RLO is it if there are no operations beforehand? What memory area does it use for that particular RLO? Moreover, what is the Boolean bit logic string in this case? I presume it is all the lines up to the '=' sign. The confusion is also caused by instructions (FR, L, T) which are not logical operations or RLO, although there is associated memory bit with them. I'd be grateful if you could clarify this matter? Many thanks!

  20. A2SH PLC

    Whisper_here posted a topic in Mitsubishi

    I have encountered memory backup battery failure/fully drained in MITSUBISHI A2SH PLC.So RUN LED started flashing on PLC. Thus no field parameters values were being shown on HMI. I connected PC with PLC through serial RS232 cable using GX DEVELOPER 8 , the connection test was successful. Then I tried to download my project saved on PC to PLC, then I was amazed as It asked for a keyword. However when the backup battery was working , I downloaded the same project but it did not ask for any keyword. Can anyone explain this. Now the real problem is that the program was developed by somebody long ago , to whom I don't have any contact right now and I m helpless as I don't know the keyword and can not download the program and thus my machine is at halt. I tried to clear the user memory from online menu , but it says the function not supported. I m stuck and frustrated . Anybody 's help is greatly appraised in anticipation. Of course I m not asking for hacking a keyword. Just to know how can I make my system functional. Thanks everybody.
