  1. Problem: I am getting a control sync fault on 2 recently installed kinetix 5500 but only when my programing PC is connected to the machine network.  Install and setup all went great over a 5 day period.  Then all of a sudden I started to get this fault. Sometimes 100 times in an hour.  As soon as I go offline, and unplug my PC the problem goes away.  I have also tried another PC connected to the Machine network and still get the same result.  Sometimes machine can run for hours with my PC connected with no problem.  I do not have to be online with controller for fault to occur. Setup: I have the 2 K5500's ethernet ports daisy chained together, and then connected via shielded CAT 6 cable directly to port 2 of the Compact Logix Controller Coarse Update is set to 3.5ms and utilization's are at 33% and below.(I have tried the default 2ms with same results) Ethernet modules are configured with FW rev 7.013. Machine network is isolated.(not connected to plant network or internet) Equipment: Compact logix L33ERM Running version 30.01. There are a total of four servos in this system all running over ethernet.  2 Kinetix 350's(not affected), and 2 kinetix 5500's. I have tried: separate ethernet cables for each drive ran through a switch different ethernet cables resetting coarse update speed connecting a different PC for programming   I am just not sure where else to go with this.  Thanks in advance for any help.  
  2. Hi all , I have been using MELSEC - Q series plc for the past two project i dont find any issue with that but for the third project  used same PLC same model but there is issue which I found unable to resolve  The issue is when i try to communicate PLC using LAN cable by direct ethernet connection it works normally but by communicating using HUB network I cannot communicate, I checked all the parameters setting, I dont know what is the issue even contacted mitshubshi service to troubleshoot but they are not responding  So here i am for your guidence to solve this issue   see the images below to analyse this issue This connection is direct ethernet connection which works normally    The parameters are set and writed to PLC The IP is set to my PC for communication  When i try to find the cpu in the network it shows the cpu IP  After that I checked for connection Test it show error I have also attached the Network route which i used to communicate  Network Drawing.pdf I hope someone will help me to solve this issue Thank you , madhan ravichandran

    naderyz posted a topic in Mitsubishi

    Hi My system : plc Q03ud , simple motion module : QD77MS4 , software : Gx works2 , Application : rotary table and unit degree I send position and speed from HMI ( got 2000 ) , my problem is that when i want send 90 degree for position ( dmov d0 u0\g2006 ) , i have to enter the 9000000 from hmi . and for speed i have similar problem Position hmi ( 9000000 ) ===>> motor rotate 90 degree  Speed hmi (100000) ==>> motor rotate with 100 degree per min
  5. Hi, Does anyone know where to get EDS files for GX Works3 ?  I can't open a file that I need to access because it has an "Unsupported Module". The module is 007ER-1FL2-T, it shows up on the Mitsubishi website but I cannot see any links to EDS files or any software related to this module. Cheers, Olly  
  6. I currently have two NX1P2 PLCs communicating back and forth over ethernet IP. However, I am looking to expand this project across multiple PLCs and I need a way for one PLC to see all other PLCs that are connected to the LAN network via Ethernet IP. I can use the _EIP_EstbTargetSta[255] function which is a boolean value that returns true if there is an established connection  to a device where the last octet of the IP is specified in the array [255].  This function works well but my PLCs are configured with the subnet 255.255.0.0. And I need to see the connection status based on the third octet. Is there an existing function that I can use, or is there a way to view the full structured text for the _EIP_EstbTargetSta[255] function and modify it to suite my specific application? 
  7. I have a ne1a safety plc I am trying to get online with. I have Network configurator V3.74. I have installed the usb driver and it is connecting to the device. When it shows the network to connect to I click on it and get an error that says: File load was failed. The specified file is protected by user password. In order to use this file, you need to install the Network Configurator for CIP safety,  Anyone know of this software or upgrade? I didn't find it on the omron software listing. 
  8. I have a 1747-L30B SLC Brick and it is set to load from EEPROM on boot S:5/8, Error S:1/10, and Run S:1/12. I need to make changes to the program and then store it to EEPROM via "Comms>EEPROM>Store to EEPROM."  When I attempt to store the program with changes, it displays the message "Insufficient Memory Module Size." I assumed the EEPROM memory was maxed out, but I also uploaded the existing program currently stored to EEPROM, made no changes, and attempted storing it back to EEPROM and received the same message. Any advice?

  9. Change Subnet On CP1L PLC

    OmronOmicron posted a topic in CX-Programmer

    I am trying to change the subnet of this CP1L plc. Currently it is at 192.168.250.*** and I would like to change it to 192.168.54.***. I already tried starting fresh by writing to the controller with ip 0.0.0.0 and then putting my desired ip address after. When I try to write to the controller with a subnet other than .250 for example 192.168.54.13, the controller saves the node address(.13) but keeps the same .250 subnet which results in me being able to ping 192.168.250.13 successfully but get no response from pinging 192.168.54.13. Yes I did change my local network card when pinging different subnets and also did a network reset in CX-P after every ip change. Let me know if there is anything I am missing!! 
  10. Hi,I am running a Windows 10 VM with Rockwell Studio 5000 on a Windows 10 host PC. I communicate to the PLC network through a USB-C to ethernet adapter. Occasionally, the communications drop out, if this happens the only way I can re-establish comms, is to shutdown the VM and restore defaults in the virtual network editor, as this can happens a few times each day, it can be very frustrating.When this happens I cannot ping the host either, until the defaults are restored and the VM re-started.I am using the bridged connection in the VM.Can anyone help with this?Thank you
  11. Currently have a A1SJ71E71-B2-S3 in the system for coaxial (thin) ethernet (10BASE-2), it's connected to a conversion module for TP-cable and from that then to a PC with plain TP network card.  I was thinking about getting an A1SJ71E71N3-T to replace it and that way get rid of the converter from coax to TP. I wonder if it's possible to just have it hooked directly to the computer without hub - if I need a hub there's really no point in swapping - as there's still another thing between the computer and the PLC system that can cause problems. I was looking through the manual at mitsubiSIH.com and they seem to think they are connected to large nets with a bunch of hubs, PLC systems and computers. Appreciate thoughts and help. 
  12. Hi, First of all, thanks in advance for those who support and advises. I have a Modbus/TCP operational network as shown below. However, at any 1 time only 1 LAN is able to communicate instead of both LAN networks of the device. In another system with S.E Premium Unity PLC, both LAN networks are able to communicate at the same time. Thus, I would like to enquire if this is a limitation of Quantum NOE 771 whereby only 1 LAN can communicate at any one time or whether I have missed out any parameter/configuration settings? Any issue on the IP address configurations? Please advise. Thank you very much for the advise and assistance.

  13. Help with LAN network

    Cwayman posted a topic in Mitsubishi

    I am trying to set up a brand new network of PLCs and GOTs in a classroom. Something I haven’t ever done before.  I’m using simple Ethernet and going from a pc to a switch then the switch to each device.  I can not get anything to communicate to each other.  I can read from one GOT or one PLC but that’s it.  Any help would be appreciated, thank you!
  14. I am trying to set up a ifm AL1322 EtherNet/IP IO Link Master to communicate with a NX1P2 or CS1 PLC. When using Network Configurator I have added the EDS file and added the AL1322 to the network and set its IP address.  It shows all the parameters in the device but if you make a change it says it has downloaded but nothing on the unit changes.  If you make a change to a parameter and then verify it says there are no difference even though there are.  I have set up the communication with the PLC but there is an error  Establishing a tag data link connection failed. This is the same for both the CS1 and NX1P2. I have also tried setting it up using Sysmacstudio for the NX1P2 and get the same result.   I have had the unit back to ifm and there is no issue with it running with an AB PLC.  I can also communicate with the unit using the ifm LR software. Any ideas why the Omron software is unable to read from or write to the unit? ifm_IOL_Master_AL1322.eds
  15. Good day everybody,    Currently I am working on an application using 3-axis controlled by a QD77MS4 Simple Motion Module.  In this case, I have already set up most of the configuration, but when I try to execute the program, I get the following error:   SP. UNIT ERROR - The location designated by the FROM/TO instruction set is not the intelligent function module/special function module.  - The module that does not include buffer memory has been specified by the FROM/TO instruction.  - The intelligent function module/special function module, Network module being accessed is faulty.  - Station not loaded was specified using the instruction whose target was the CPU share memory.   The QD77MS4 Module is mounted in Base Slot #3, so I use U2\G800, U2\G1500, etc... to Read/Write from it.  The Diagnostics tool indicates the error occurs as soon as I try to access the U2\G800 Buffer Memory. If I set this part of the program to No Execution the error is no longer displayed.  Additionally, if I try to monito the Buffer Memory area of the Module, it says that "The Module Stat Address is incorrect".   I already tried changing the position of the module in the base (Slot 3 --> Slot 1) and changing the corresponding values to reflect that, but still the problem persists.    What am I doing wrong? Is there some kind of configuration I could be missing?    Thanks in advance for your help!   
  16. Hi, I'm currently in a project where I'm putting up together a network where a CJ2M-CPU33 is reading the memory of 4 G9SP safety controller and communicating with an unchosen HMI. Since I'm new to Omron communications, I've decided to set up a network composed of only 1 CJ2M-CPU33 and 1 CJ2M-CPU31, both equiped with built-in EIP21 port, to help me understand the FINC protocol used to Read/Write and other commands from one PLC to another. I'm currently trying to use the CMND(490) function in the CJ2M-CPU33 to attempt and read part of the D memory in the CJ2M-CPU31 without success. I've tried many ways of sending the Hexa code to the PLC I'm trying to read the memory from but always come up with a 0401 end code (Service unsupported: Undefined command) or nothing at all when my Hexa code is really messed up. It's also good to know that the informatician of the company has succesfully read from the memory area but with his computer. I have provided with this topic an overview of my setup, settings and program in the PLC that is performing the CMND(490) function. I'd also like and take this opportunity to say that I really don't understand the settings in the FINS/UDP and FINS/TCP menu and when and how the PLC is using these protocols even if I've read tons documents on the FINS protocol. I find that that Omron's doc is complete but kinda lacks of setting and program examples. FINS_Problem_description.docx

  19. How to scan Ethernet/IP network?

    crustyneon posted a topic in CX-One

    Scenario: You show up on site and the only knowns are Omron PLC and EtherNet/IP network. You have a laptop loaded with CX-One, an ethernet cable, and the ethernet port that is connected to a known EtherNet/IP Omron network (you can not see the PLC). I have previously worked with Siemens systems and used Primary Setup Tool and Proneta with wonderful results. Do similar tools exist for an Omron environment?  Question: How to (relatively quickly) scan an EtherNet/IP network for connected devices without knowing their ip addresses?  
  20. hi, I have a question regarding DH+ network for those who has really experience.   1.

  21. Hello, My coworker and I are commissioning a new panel. We have a 1732-AENTR series C remote IO thats Rev 6.1. The project file from a previous identical panel has the module at rev5.3 in the project tree. I downloaded the AOP and ran the installer, it worked no issues. My co worker then did the same thing but now the module is unrecognized in the project tree and the module is missing after installing the AOP. Im concerned he corrupted something. I tried uninstalling and reinstalling the AOP but no luck. It works on my computer but not his? TechConnect said something about corrupting the aop core. My coworker did the first install and he was getting confused about zip files and the virtual machine we run rsl5k on. Maybe he broke it? any suggestions?
  22. Hello Sirs! I have a problem with PF527. I get alarms 'control sync alarm' and 'module sync alarm' occasionally. I suppose this meaning that PLC is missing some data from the PF527 device. How to confirm this or what should I do with the problem? Any ideas? Motion group update period is 8ms. Also this device is the last device in the ethernet line. I am thinking to pull the cable directly to the switch near PLC. I am not sure does it help?  

  23. Q02 / Q71E71-100 Network settings

    PlcAmtr posted a topic in Mitsubishi

    Hi experts :D Can anyone help/try to help  with the following conundrums: a) when changing the Ethernet Operation settings from Binary code to ASCII code, the setting are 'saved' in PLC settings, meaning that ASCII code is read as selected after a restart, but the PLC accepts commands and responds in Binary code. b) when adding a new TCP port, the new port is 'saved' in PLC settings, meaning that read as selected after a restart, but the PLC refuses commands on that port (the "Open" LED on the Q71E71-100 card turns on for the duration of the transmission but no reply is received from the PLC) notes: setting software: GX Works 2 target test software: Custom made Driver for MC protocol. (tested and working with FX and Q series  and with ASCII and Binary code) PLC model Q02 (reset performed by removing the battery for more that 2 hours) ports used for test are: 5500 and 4999 (decimal) found 5002 port opened by default (no open setting required) PLC network module Q71E71-100 (new)   I would upload screenshots of the settings but I get this error: "There was a problem processing the uploaded file. Please contact us for assistance."
