  3. Omron CJ1m - bluetooth connect

    Hi, I write app to smartphone to communication omron CJ1m and Android. I want to connect devices by standard bluetooth. I plug in bluetooth adapter directly to omron RS232.  I want to ask you, how i can connect by FINS command. Bluetooth device baud rate is set 9600. If i connect to omron, i sent code: "AC01" and i sent how long as omron return me "AC01" ?? And what's next command i sent? If I want read CIO 10 i sent: "0101B000000A" ? and FCS and "*" ?? how i calculate FSC? Is it XOR my data sent? 
  4. 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

  6. End code unknown

    Hello I have problems when  trying to communicate with my cj1m. Recently, i have added an ETN11 ethernet module and i can now communicate with the PLC using CX-programer. But the problem is i cant communicate with my python script to read something. I just want to read CIO area 2 from bit 0 to bit 15. But Wireshark tells me that the end code is differente than completed. I cant find anywhere the end code 9005, any ideas?   Thanks  
  7. 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?
  8.  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  
  9. 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.  
  10. Please,if anyone has a working program (.stx).I need it to test a PL7 JUNIOR software
  11. 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 ... 
  12. 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?
  13. 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 ?    
  14. 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.

  15. 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
  16. 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?

  19. PWM 891

    Hi everyone, im using CJ1M CPU21 ... I want to ask how to disable origin search function before I using PWM(891) instruction? This is because i noted that both PWM output 0 cannot share with the origin search function.     
  20. CJ1M to Movicon Interface from Message

    Hi, Im starting a project to interface a PLC function system and im still confuse about what protocole to choose to communicate (CJ1M CPU13) with Movicon interface by the way i have three PLCs with ETN and the others just the RS232C . The project is to interconnect 11 PLCs ( CJ1M CPU13) with a HMI in order to see the working process of the PLCs .  I could use your help solving my problem.
  21. Looking for Socket TCP/IP communications program examples for Mitsubishi PLC iQ-R R04CPU using GX Works3, to compliment the Mitsubishi Ethernet manual Socket commands instructions. Unfortunately, the manual is missing real application ladder logic illustration examples of these commands. For example, the Socket Open Connection command, does not describe in what order or format to enter the IP Address.   For example, to enter IP Address 192.168.1.100, does the most significant octet 192 is entered or stored first in the lowest memory storage register (Big Endian format) or does the least significant octet 100 is entered or stored first in the lowest memory storage register (Little Endian format)? I am trying to write a simple Socket TCP/IP communications command that will write about four registers from an existing Mitsubishi PLC R04CPU (Socket Client) to an Allen Bradley PLC ControlLogix (Socket Server). .
  22. Hello,  As the title indicates, we have a micrologix 1400 that has been installed for a long time.  Recently it faulted out on 71h and was in Remote Mode.  Do these PLCs revert to Remote Mode when in a fault condition?  We placed it back in Run Mode and everything worked fine, but how did it get to Remote Mode in the first place? Thanks,  J 
  23. Hello, I was hoping for some help in trying to read/write to a handful of bits in a CJ1M-CPU13 controller from a Compact GuardLogix. The CJ1M rack has a CJ1W-ETN21 card that is already communicating to a handful of Yaskawa drives. Is it possible for me to communicate with this controller from a CLX unit over ethernet? I don't believe an ETN21 card uses EIP but is there a way around this? Right now, I'm struggling to even find the IP address of the ETN21 card as the CX-Programmer file provided to me by the customer does not have the card in the IO configuration and I've never worked with Omron PLCs before. I found a CJ2M to CLX guide but it assumes communication over Ethernet IP and the ethernet port is native to the controller. Any help at all would be appreciated. Thanks!
  24. Relay Digital signals

    I have a CJ1M-CPU13. It will be used for a prototype and later if successful, a better PLC fit will be employed. This system does not have the ability to drive pulses for servo control. However, will this system relay a digital signal at ~1kHz? I also need the PLC to count the pulses, reset at 1000 and start again continuously and never miss an input pulse. I see that the published transactions give  <15 microsecond decision times. I would think it would be no issue. Thank you.
  25. I'm using Controllogix L61 redundancy system as a slave with DCS using ethernet tcp/ip socket programming. The communication between master and slave will fail after a switchover. Kindly give solution for this. Thanks and regards, Rasu
