  1. Hello, I got a new work job to design a cycle tester for a mechanism to make sure will work for at least 5000 cycles open - close. I never made a pls program I start researching few days ago and seams to be very complicate to make it. I have a TM221C16R PLC from Schneider. please help me with some instructions. the cycle tester will have a start pushbutton, stop pushbutton, door open switch, one air cylinder with solenoid to push and pull and a counter. Thank you, Romica
  2. 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.
  3. 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?
  4. 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.

  6. 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.

    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  
  8. hey!  I'm pretty new to PLC's, and I'm supposed to ''teach'' the people at my internship how this PLC works, but I have encountered a problem.  I've gotten pretty far with all the digital programming and understanding how everything works, but I just can't figure out how the analog inputs/outputs and programming works...... I've had a fair explaination on PID and how this works. I've searched the web as well to figure out what PLC instructions to use.    I hope you can answer my following questions.    1, what are the most used PLC instruction blocks which I can use for temperature control, and how am I supposed to use them? 2, Could you please give me an example on how to use PID and what numbers will I need for the calculations? 3, what are the most used PLC Instruction blocks (apart form the analog ones) that I should include in my tutorial?   this is my setup: Ethernet switch MOXA EDS-205 Plc voeding PA202 PLC CPU CJ1MCPU11-ETN Digital IN (16x) CJ1W-ID211 (SL) Digital IN (16x) CJ1W-ID211 (SL) Analog IN (8x) CJ1W-AD081 (SL) Analog IN (8x) CJ1W-AD081 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) Analog OUT (4x) CJ1W-DA041 (SL)   thank you soo much for looking at my question and considering helping me! the OMRON helpdesk hasn't been very helpfull.    kind regards,    Deuslupos,
  9.  hello there ! all the variables are reals ... can anyone explain why i get a different result when i calculate c2 first ??? the two programs shown in the pictures are exactly the same ... the only difference is the posistion of c1 and c2 . please help me . It's not a logic  attitude in programming ..... Any ideas? Thank you

  12. Hello! I have a PLC S7-1200 (1212C DC/DC/DC) and a few question about programming S7-1200 in TIA Portal v13. 1. I want to make "upload station", because I am not surre whichone project is the last. But, when I start upload data, the error hapens, and the decription of error is: The name of the station "S7-1200 Station_1" is already in use in the project. How and where can I change it? 2. And the last question: I try to connect my S7-1200 and Weintek simualtion. There is all time :"PLC not connected". I have chceck everything: PLC is OK, communication PC-PLC ok (ping ok), windows firewall off, administrator rights ok, configuration made with manuals, (CPU - Siemens S7-1200, IP: 192.168.1.100, port 102, tags import - ok.) I have read the manual many times, and check settings - nothing change. Maybe have someone problems like this, and found a solution?

  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. I am converting a PLC-5-40 processor that also has a SST side car for Profibus Dp communication to BK3100 modules on the equipment. To a Control Logix L-72 processsor using a Molex SST-PB3-CLX card to the Profibus modules. Everything went some what smooth until I got to the SSI transducers in the Profibus. The word arrangement is not coming in the same as with the PLC-5. Is there anybody else that has run into this problem and is there a solution. I have contacted Molex, Balluff and Beckhoff the first 2 got back to me I am still waiting on Beckhoff.

  15. 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.

  17. 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
  18. 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!

  19. Panasonic FP-X C30R

    jaymac posted a topic in Other PLCs

    I'm very much a novice to plc programming. I've dabbled in years past with Mitsubishi FX units with Medoc long before G X Developer became available. I also did a bit on Schneider using Zelio software. All very much simple stuff using ladder logic and internal relays But I've got me a Panasonic PLC that is surplus to requirements where I work and I would like to investigate the possibility of using it for practice purposes. Who knows, I might even get it to do something useful. I expect it is a few years old - its got a version No 2.4 and what seems like a date on it 080916. First query - is there software available for this item. Second query will it be compatible with a computer running on Windows 7. I've checked on the internet and see that there is documentation out there the plc. I decided ask for some informed opinion from before I go too far into what turns out to be a "cul de sac". Regards jaymac.

  21. Hello all, I am trying to download a new program to a AB 1746-BAS SLC 500 BASIC board via RS-232 connection through a Windows 98 laptop running Hyperterminal. While the BASIC board is connected I verify connection by waiting for the board to print out its information in the Hyperterminal program and then enter "CLEAR", "NEW" and finally, "LIST" in Hyperterminal to wipe any program from the board and verify the board is clean respectively. Then I load the new program via a .TXT file using the "Send Text File" option within the Hyperterminal program. After the program has finished loading I than type "LIST" to verify it has copied over correctly. I than switch the SLC over to "Program Mode" via the key. After doing so I type "RAM" to select the program i just uploaded to the BASIC board and then type "PROG" in the Hyperterminal program. I than receive the "Programming Sequence Failure". If anyone has any advice as to what I am doing wrong it would be greatly appreciated. Below is a list of everything I have set and researched. Thank you in advance, James -Laptop: Windows 98, Hyperterminal -BASIC board (programming): JW1 pin: 1-2 3-4 JW2 pin: 1-2 3-4 JW3 pin: 1-3 2-4 JW4 pin: 5-6 3-4 -RS-232 9-pin connector: Pin 2 connected to Tx Pin 3 connected to RX Pin 5 connected to ground Pins (4/6) crossed DSR/DTR Pins (7/8) crossed RTS/CTS -Hypterminal: Direct Com1 bits per second: 1200 parity: none stop bits: 1 Flow control: Xon/Xoff Settings/properties: -> Emulation VT100 -> ASCII line/character delay: 30 milliseconds check box: Append line check box: Wrap lines... -Manuals: 1746-rm001 1746-pm001

  24. 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.
