  1. Hi,     I'm trying to communicate Omron CP1E unit with PC via serial port using hostlink protocol.  I need to read the Timer/Counter SV value and write the timer/counter SV values to the PLC.  I'm able to use other C mode commands (like RC (timer/counter PV read), WC (timer/counter PV write) etc.) but when I give the command for Timer/Counter SV Read 1 which is R#, I get the response as IC (Undefined Command).   How do I write or read the timer SV Values?  Example command and response : @00R#TIMH001028*  (TIMH is the high speed timer, 0010 is the timer number and 28 is the FCS) Response: @00IC4A* Is is that CP1E doesn't support these commands? If so what is the equivalent command that I should send inorder to perform this? Please help.  
  2. Hi,     I am trying to establish communication between master and slave through modbus rtu rs485. But I am experiencing error code 7378h. I already tried to make the values of Request Interval Timer from 100 to 200 and Broadcast Delat Value from 50 to 100. But the error still persist. Any tips how to solve this issue? There is no error on the slave evices.
  3. Hi every one ! I cannot use register D128 - D255 in the program when I create a program that uses the Block function in the PLC mitsubishi FX1S, it gives an error :  A device of the device range set in the device/label automatic-assign setting or a device which cannot be used due to system reservation is being used.Help me,Thanks !
  4. Folks, we have a set of Mitsubishi Q12PRHCPU (redundant) running effortless since many years. CPU-A as standby and CPU-B as Control. Recently we noticed BATT low alarm on CPU-B. So we arranged for a spare battery Q6BAT and started the procedure as per manual(attached procedure and flow chart). We did memory copy from Control to standby (as prescribed precaution) and did the Reset of Standby PLC CPU-A. Memory copy from B to A completed successfully 100%. But the BACKUP LED did not turn Green from Red & Error LED kept flickering on standby CPU-A. CPU-B remain in Control but backup LED turned RED. From system monitoring we found that there is a Error 6000 (FILE DIFF.) observed in One of the .QPG (program 00-MDBUS.QPG). We tried to reset it but were not successful. We are surprised that why does the program differs when it was copied from CPU-B to CPU-A using the memory copy. Still we did the VERIFY and found no difference between the programs in CPU-A & CPU-B.  Can anyone explain the cause of this issue and the solution. Please note that the CPU-B is still in control and plant is running. Backup LED on both CPU are red which means (redundancy loss) and error LED on standby CPU-A is flickering RED. There is no error in the CPU-A (Control) -we checked this using the GX Developer. Also attached here are the image of the error and error help. Thanks in advance.

  5. Hello, I need to connect multiple barcode readers (SICK CLP510) to a PLC (FX3GE-40M) for a university project. I need a minimum of 3 bar code readers, but only have one operational, connected via an additional modul for the use of rs-232. The only other port I can use is a miniDin 8, which is a build-in rs-422 port. Because this is a university project, it needs to be as cost efficient as posible. All the readers are CLP510 (pin-out attached bellow) Thanks Becky Pin_out___wire_colour___signal_comparison_CLP100_CLP510_CLV60x.pdf

  8. Hi everyone! I have a question to all of you guys - do you ever use any software or online tools to manage your automation/electrical engineering projects? I have worked in a number of companies and have seen various scenarios, from using excel tables to run multi-million dollar projects to using proprietary SW for every little tiny project. Unfortunately I do not have experience working for any major big integrator and am very curious how projects are managed at this level (and if every engineer likes the way it is handled).  Additional question - does anyone have ever used a software to automatically generate the PLC code? I know some companies develop products to generate the "skeleton" of PLC program and I think it is a great thing to have.
  9. Hello. I am working on a pilot project building an automated RV park. Our goal is to have people sign in online, or in person at a kiosk. Make their reservation, payment, and get their confirmation e-mail. In that e-mail, will be a QR, or Bar Code, that when scanned at the gate opens the gate, and starts a light that flashes at the site they rented. Power will then be turned on at that site, and a timer in the process will begin, based off their rental time. Once their time has expired, the power at the site will be turned off, controlled by a PLC, and relays.  So I am looking for help in all directions. I have some leads on some plug-ins for Wordpress that offer reservations, and other plug-ins that do Bar code production. As far as the web part I have that covered. We can generate a custom barcode, or QR code based on individual rentals and those can be sent to customers. So what I need is someone to help point me in the right direction of equipment that can speak between the online Barcode process and the PLC to allow a process to begin when scanned. Based off their rental parameters their power is turned on or off. Perhaps a SQL query in some form? I haven't used it, but am aware of its capabilities, and this does seem like an application where it would be used. Is there anything that you have used that are tried and true? I know it's a strange request, just hoping someone bites. Thanks in advance for any ideas, I look forward to solving this puzzle, one piece at a time. 
  10. Major Fault

    I have a compact logix with a major fault. Please see my attached file for the complete fault message.  Code 20 array subscript too large. or control data type to large or invalid. Has anyone observed this issue before.  The PLC is a compact logix model.  Every time, the controller is switched from program to run the major fault occurs within 5 seconds.  The fault can be cleared but then it comes back in a few seconds.  I have been told by my tech that no program changes have been made.  Could there be a hardware/wiring issue? Thanks much Document_1234.pdf
  11. Hi, This is my first time to start an actual project. I have some basic to intermediate programming background with Seimens PLC in the past but with no work experience. I bought an old bandsaw machine for a very cheap price. It works fine on manual operations but I want to try and test if I can make the fully automatic function back. The current PLC installed in the machine is a Shihlin Electric SEPLC A1-30MR. It look old and the port is not familiar to me. I also have no idea if I can even get the program inside or not. Thus, I plan to replace the old PLC with a new one. Here are my questions. Should I use a PLC or can I just use a digital controller like Logo ? I need to use a loop for counting how many cuts it should do. And how many times the machine should repeat the push of my stock out per cut. What else should I consider when choosing a PLC or digital controller?   Thank you in advance. 
  12. Hi, I've been having a problem with my Schneider setup, and I can't seem to figure out the problem. I'm using Machine Expert Logic Builder and Vijeo 6.2, and I can't seem to download to my PLC. I can download to my HMI just fine, but my HMI comes back with the message as mentioned in the title. Also when I perform a full download, machine expert comes up with the message "Could not connect to the device for item "xx", selected target system "PLC name" is different from the connected device "HMI name". The weirdest thing is that machine expert shows my PLC just fine, but doesn't show my HMI. I have no idea what to do, as I feel like I've tried everything. The IP range is fine, subnet is fine. The driver in IO manager in Vijeo has the PLC nodename in it, so that shouldn't be the problem either. Does anyone know what to do in a situation like this? Thank you in advance!
  13. Calling a Timer in ST code.

    Dear all, In a state machine I have certain states which need to have a timer to handle timeout errors, that is, if the FSM remains too long in a certain state without getting the conditions to transition to another one, it will produce an error. My current code is using a TOF with an input variable that will be triggered upon entering the state, I call the function block, and then turn the signal off so it starts counting: TRIG_STOP_TIMEOUT := TRUE; TTO_GLOBAL_CYCLE_STOP(IN:= TRIG_STOP_TIMEOUT ,PT:= T#15s ,Q=> ERR_GLOBAL_STOP_TIMEOUT ,ET=> CLK_GLOBAL_CYCLE_STOP ); // TOF TRIG_STOP_TIMEOUT := FALSE; For some reason, the counter does not work. I don't know if I should trigger the signal on in one scan and off on the next. I thought about using the system 1s clock as a trigger (SM412) but the description of the TOF function block states whenever the input is ON, the output will be true, and the timer will only start counting once the input is low. The other thing I thought about was to use the TOF_E instead, with the clock as a trigger, and just set the enable signal when I'm in the state, but I'm not sure it'd work correctly, either. Any suggestions?
  14. Hello everybody,   First, I used the BMX NOR 0200H module associated with a GSM modem, for the time stamp and the problem is at the level of data recovery (slave PLC), I received the value of the variable (it's OK), but instead of the modification date of the variable, I received the send date (from the master PLC to the slave PLC).   After this application, I tried to use Web Desinger to do the timestamp by recovering a .csv extension file, but the file does not generate in the memory card (I accessed the module's memory card by an FTP client).   At this stage, the BMX NOR 0200H module, does not respond to a new configuration or a modification (either by Web Designer software or by Web Server, even these last two confirms me by a dialog box that the module has accepted the change).     Thank you all for your attention.    
  15. This may be more of a Zebra question than a PLC question but I will post it here. I am using Zebra's Network Connect to enable communication between a CompactLogix L13ER and a ZT410. My issue is that the QR Code omits the 5 elements of the array in Field 1 of the CompactLogix. I expect the first two elements in the array to be ignored per the manual but the first 5 has me puzzled. All the characters in the text shows up fine. I have attached what I am seeing. If you have a QR Code reader, you can scan the QR Code.
  16. Change CIP Service Code

    Hi all, This is my first post here, I read through the FAQ, searched the Allen-Bradley forum and this one for my question but couldn't quite find what i was looking for. My main questions is: Is it possible to programmatically change the service code of a MSG instruction?  It is possible to change the class,  instance and attributes but the application I'm currently writing would be a lot simpler if all I had to create is one instance of the MSG block (and its data) . The only thing stopping me is the service code.   Edit: I'm using a CompactLogix 5380-L306ER   Any input is greatly appreciated!
  17. Automax Reliance Electric Drive

    I have a Reliance Electric Drive Digital I/O Module 57401 that won't close the MCR contact R1/B3.  I believe I've narrowed the problem to the 4 input signals WDOK, BD INIT, INIT, FAULT on the Multibus.  Does anyone know how to access those signals from AutoMax Executive.  I have also made a breakout cable, out of an old output card to access those signals.  The problem with the breakout board is that P1-16 does not carry over to the empty slots 5, 6, 7, 8 and slots 11, 12, 13, 14 are full with the drive cards in question.  I would also like to find out what drives those signals, especially the Fault signal on P1-16 of the Multibus.
  18. Hello  I am currently trying for testing purposes an Mitsubishi Servo Amplifier M4-J4-TM, which has a Servo motor (also from Mitsubishi) controls to integrate in Beckhoff's TwinCat 3. The controller is directly connected to the computer via EtherCat and is also communication between TwinCat and EtherCAT device is detected. But when I switch to online mode and try to control the engine manually, it always comes the following error message:  Error 51 'TCNC' (500): 'Axis 1' (axis ID: 1): The axis or the drive is not ready for positioning (error code: 0x4225)!  Somehow I miss a step to the valid activation of the engine. ?? In the documentation of Beckhoff and Mitsubishi there is no indication. Actually that should work like that. Has anyone ever had a similar problem and knows about advice? Thanks in advance in advance and many greetings
  19. Hey, I have a 1763 L16BBB...when I plug the 1762IF20F2 analog card in, I get a 0189h error code. Any help would be appreciated. Currently looking at doing a bootp on the plc to get online...no ip
  20. Hello everyone, I'm currently trying to communicate  via ethernet with a Parker drive IPA15-HC. I'm using a 5069-L306ER CompactLogix 5380, revision 30.011. There are add-on instructions that allow you to control the drive, but since they're really basic I'm trying to use message instructions to get more data out of it.  The knowledge base provides a zip named IPA_AOI_Rev4, that includes the add-on instructions and the program you should download to the drive to use them, this is the current file downloaded in the drive. Now, I've tried different msg configurations: CIP Data table read, CIP Data table write, CIP Generic copying the values in the examples and I always get the same:  Error Code: 16#0001 Extended Error Code: 16#0000_0125 That extended error code is nowhere to be found, not in the Logix designer online help and not in rockwell's knowledge base. Any idea?
  21. Hi All, I am pretty new at electrical design for PLC control panels. We are a UL508A shop, so this is the code I refer to most. Something struck me as odd when I was trying to size wire for this control panel. UL508A 28.3.1 says this: The required size of the field wiring terminal shall not be less than 14 AWG (2.1 mm2) and shall be determined by: a) Calculating the required ampacity per 28.3.2 – 28.3.6; and b) Determining the minimum field wiring conductor size from Table 28.1 having a corresponding ampacity that is equal to or greater than the required ampacity from (a). How can the minimum wire size be #14 AWG? We use #16 AWG for wire to the PLC modules? Are we breaking code or is there something I am missing? Also, understanding code books can be difficult. Is there a website or place I can go to get a plain English translation? I feel like I will read a sentence over and over again to try to understand what they are saying, and feel like there's is a much easier way to say it than the way it is written. For example, "28.3.1 b" ……...what is it really saying?  
  22. Hello, everyone. I want to ask for help..  i want to upgrade HMI hakko V7 to V9.. have file hmi in V7 use software V-SFTV5 but when I open file V7 use software V-SFTV6 its cant convert and i attached the screenshoot below..  can someone tell me what's wrong?
  23. Hello, I am new to the forum. Being doing a lot of googling to see if theirs any cross-compatibility between an M241 PLC and a Simatic panel PC and stumbled across this forum which hopefully could help me out. I'm starting an automation project to automate my home brewery. The M241 from Schneider electric seems to tick the boxes for what I require.  At my work theirs a redundant Simatic Panel PC 670 just waiting to be recycled. My question is, can I use the panel pc purely as an HMI for the M241?  
  24. Hi everyone - my first post here.  I have a customer with a SLC5/01.  The controller is 1747-L511.  Battery seems good.  The fault LED is flashing.   I tried to connect to it using RSlogix500 and I got this message (photo1).  I selected 'Load From EEPROM' and got this notice. (photo2) Customer has the printed ladder but I can't tell which data types are what. everything is just numbers - no B's, no I's and no O's.  the timers and counters are just numbers too. Luckily the printed ladder has a cover sheet, which led me to the PLC2.(photo3) The rack has two 8 channel inputs and 2 8 channel outputs.  I would like to replace everything with a micrologix 1400 or something, if I could translate the code. Can anyone advise on this matter please?
