  1. Hi, I am very inexperienced with Omron hardware so apologies if this is a daft question. I am trying to use Kepware to retrieve data from a CJ1M-22 PLC via the peripheral port using RS-232 and the Toolbus Kepware Driver. The RS-232 is provided by a Brainbox ES-246 Ethernet to RS-232 convertor. I have no problem accessing the PLC using this peripheral port via the programming lead but I wanted to know if anyone had successfully pulled PLC data through this port? Many thanks John
  2. Hello everyone! This is the first time I use Micro850 controller (2080-LC50-48QWB) and after I made a really simple programme (just for testing) I wanted to download it to my controller (which I was able to see and connect to via Ethernet and USB normally) and I got a message saying that firmware version didn't match (programme - v9, and PLC - v4). So I found some datasheet where was explained how to upgrade device firmware with ControlFLASH. I started the mentioned software, choose the right controller, and I choose the version 9 and the process started, but near the end I got the ERROR message, and the update wasn't finished successfully. So my controller went to fault (FAULT red light flashes) and now I can not see it in RSLinx nor via Ethernet nor USB. Does anyone have any idea what could I do to try to establish connection with my controller? I have tried to change from prog mode to run, and back to prog, but the fault remains. I really hope that I didn't make some serious mistake, because we need this PLC very soon for work. Thanks  in advance!
  3. Data Collection and Display

    Currently I am using DDE links in Excel to run a live "dashboard" with our cycle times and faults/downtime. I was wondering what the best solution would be if I wanted to display a dashboard with this information on a TV within the plant but I only have 1 license of RSLinx Gateway. OPC perhaps? SQL? I attached a picture describing what I need
  4. Hello PLC expert i need your help. i want to use OPC communication and Matlab to read and write data from/to a Logix5561. A Topic is already configured on RSLinx. On my PC i installed MATLAB and i can connect to the OPC Server using Simulink opc Toolbox. My Problem occurs when i want to add Items, i receive a Simulink error saying Name space Browsing not avaible. and Matlab says could not retrieve name space for Server. Error was: StartItemId is not a branch in the Server Namespace Additionaly i have RSView32 as an OPC Client too and although it is working fine, there is an error saying: OPC Error :Server the item is no longer available. could the error in RSView32 be the root cause of my Problem ? edit: I forgot to mention, that on Simulink opc read and opc wirte box have the Mention disabled in brace .

    The BOOTP/DHCP is unable to function because port 67 is being used by another process Throwing this in here because I have a plethora of problems with BootP since Win10. It is rare that I use Boot/P, we don't need to install a lot of new devices, as we are an OOM. Had an old 5/05 that should of had an IP address but did not and was not immediately discoverable by other means. Could not read through the serial port because it was set up as half duplex and apparently RSlinx and/or my cable would not work on half duplex (auto find could not see any PLC's). We tested the serial port of an identical 5/05 and see the same issue, moving that to Full duplex would allow a connection. We looked at the last program back up we had and found that it was indeed set to half duplex. So, suspecting that PLC did not have an IP address, I received an error which is the first line above. It also said it was a service host with PID 10262 that was using it. I opened my services and looked for PID 10262, it was being used by a "Shared Services" function, which I stopped. Then BootP opened and worked fine. Reality is, that if I reboot, this service will likely restart and cause the same issue and I don't think I can keep it off all the time. If I can find a way to reassign this service, I'll post more here.   Good luck
  6. Fatek PLC Communication Problem

    hy all. i am having an error while communicating with fatek plc. when i communicate it gives an error. " Com port open fail, plz check if this port is used by other programme when we online the PLC (Fatek/ WinProLadder). kindly Guide me   as it looks like port is already used by another program . and i dont know how to kill that program ..       
  7. Hello,   Target:  I'm looking to make an excel macro that will take an IP address and pull the components on that specific backplane. Pretty much how RSLinx Classic OEM does it, but it will save me a lot of time if I could automatically put the results into excel. Example: Enter IP "" into excel, run the macro, and have it fill in the components on the backplane below. 00, 1756-L73 LOGIX5573 01, 1756-EN2T 02, 1756-DNB 03, ... 04, ... Any help that could get me toward this would be amazing. I'm just not sure of the code that would do this.   Thank you, MalSmith21
  8. Compactlogix 1769 L32e

    Hi Guys, I recently purchased a 1769 L32e off of ebay. I'm able to connect to the processor through the RS232, but when I try bootp the MAC address is not being detected. I opened up RSLinx through RS232 and I noticed that I don't even have the ethernet port in the device tree at all. I also tried adding the MAC address from the processor in bootp through the add relations button, but with no success. When I go to my Local Area Connection, I can see that I have established connection between my computer and the PLC. I've attached a copy of the RSLinx capture below!!!! You guys help is greatly appreciated!!!!!
  9. CJ1M serial communication

    Hi! I would like to know how I could send information throw serial RS232 communication. I mean, I have CJ1M-CPU11 connected with ID232 and OC201 modules, and I have an optic sensor (digital input). When the sensor turn on, I would like to be able to read the information (on/off) with an application like Putty (I have the PLC connected by RS232) to develop an application and show the information on another framework. I don't know if I have explained very well. Thank you!
  10. I'm wanting to get upload the program from a CompactLogix L31 Controller.  I'm using a generic (non Allen Bradley) "C2G brand" usb -->rs232 cable coming directly off of my laptop because I don't have a serial port out.  The rs232 side of the C2G cable is a "pin out" or male end, and as you can see in the picture, the serial port at Channel 1 on the controller is also male.  I'm using a generic (non-Allen Bradley) null modem (female-->female) cable to complete the connection.  Ultimately, I'm not seeing the controller on linx.  But that's a result of me not being able to configure the driver.  When I try to auto configure this driver, Linx gives me an error saying, "Unable to verify settings due to a NAK!" btw, the rs232 cable going into channel 0 is for the HMI on the machine. A pv600 1. How do I get online and upload the program from the controller? 2. What does NAK mean?
  11. Which RSLinx License?

    Hi, I have a task whereby I have to hook a WonderWare InTouch (2017) HMI, on Windows 10 through to two Allen Bradley PLCs both programmed via RS-Logix 5000. OPC comms between the HMI PC and the PLCs have to go through RSLinx Classic. The RSLinx Classic install has a paid-for OEM license. InTouch to RSLinx has to be through Wonderware OI-Gateway using Suitelink protocol. I can see and interact with PLC-generated data items at the output side of RSLinx using Matrikon OPC Explorer.  I can also see OPC data generated by Matrikon OPC Server for Simulation from within InTouch with comms to the Matrikon OPC server going through OI-Gateway / Suitelink. However, I cannot get OI-Gateway to talk to RSLinx, and so can't connect InTouch to it.  I have now found that this RSLinx Classic OEM license might not support interaction with Wonderware OI-Gateway. However, fruitless searching means I don't know if this is the case, but I still need to find out and be certain of  the facts before broaching the whole "we actually need to buy another RSLinx license" thing with the Powers That Be. There seems to be content on the Rockwell / Allen Bradley / RSLinx website which deals with it but (frustratingly) it declined to show me that content, appearing to suggest that I needed to pay for a Rockwell support contract before I could get access. I'll not get (too far) into the debate about coolness of this - or otherwise - when we've already paid for this RSLinx Classic OEM license and just want to find out if it will actually do what's required... Cuitting to the chase, could anyone tell me please which RSLinx Classic license I need to have in the setup above in order to be able to speak to RSLinx Classic from Wonderware OI-Gateway? There are 2 PLCs which RSLinx communicates with, but the two of them comprise two 'halfs' of the same overall system. I suspect the OEM license might have to be upgraded to a Gateway license, but I just don't know. Input much appreciated please! Incidentally, the OPC server has to be RSLinx - I'm not allowed to swap it out for Wonderware OI-ABCIP or Topserver etc Thanks      
  12. RSLINX in excel

    Hi Guys! A have a problem with Excel and RS linx. I belive the communication is good. I just need a few tips, especially with excel. I have about 3000 dint value, and aI dont know how to put them in excel at once. Not one by one. THis is my first question. You can see the link: =RSLINX|MC!'Database_fifo[0].Motor_rpm, L1,C1' the next one is =RSLINX|MC!'Database_fifo[1].Motor_rpm, L1,C1' and =RSLINX|MC!'Database_fifo[2].Motor_rpm, L1,C1' and so on. I dont want to write the numbers like 3, 4 ,5 ...2560... So I hope you guys get it, sorry for the bad explanation. For this problem maybe exsiting some macro or something like that, I dont know. The second: there is some dint what is in decimal style, but acutall they are ascii, I know how solve that, with the char function, but I dont know how to collect it. Like on the picture, there is the numbers what I read from the plc, like 82 equal to R. But I want to see them in one cell. Like RKBF-355, I want them in a same cell. Unfortunaltely I cant solve it. At least until now, and I hope somebody know it by memory.    Thank you in advance!  
  13. 90 30 CPU350 serial connection

    ok running into a issue here, so we were able to communicate with the processor to download a program. transfer went fine. upon cycling power, we can no longer connect to processor. we used LM90 for the software. i've tried removing the battery and shorting out the "mem clear" points on the board, however we can no longer communicate with the CPU. we have a POWER and OK light solid on the power supply. kinda stumped here if anyone has any insight.
  14. Hi Everyone. I need help bad. For some reason the RSLinx Classic on my computer was not working. I decided to re-install it but could not do that. Then I uninstalled it  but would not. I reinstalled all others but RSLinx would not. I cleaned the registry and again did not succeed either to install or uninstall. Does anybody have an idea what is going on? Please help. Thanks.
  15. BECKHOFF CX-9020

    Hello PLC experts, I am master student currently writing thesis. For this, I have a initial task of making some changes to PLC program (Just started getting to know about PLCs- complete beginner). I have a BECKHOFF cx 9020 PLC connected to my notebook using ethernet. I am using TWINCAT 3.1 (VS) as IDE. Firstly, I cannot find my PLC IP address connected to my notebook . I added the route in the Twincat and it shows the PLC is connected. When, I am trying to run a program (activate boot project), I am unable to login to the PLC. It gives an error "login failed for application port 851". What I undertood from BECKHOFF scripts,  there is something wrong with the ADS ams net ID which I am trying to figure it out. I appreciate all the help. Thank you.
  16. I am trying to setup communications between RSlinx and Softlogix on Windows 7 PC. I open SoftLogix and configure a CPU and Ethernet module. I then cannot open RSLinx GUI since RSLinx is already running as a service. I stop the service, which automatically removes my CPU from SoftLogix but does allow me to open RSLinx GUI. However I cannot connect to the Softlogix now since it has no PLC. When I try and add a CPU I get a message that RSLogix must be run as a service. However in that situation I cannot open the GUI.
  17. I am looking for a way to communicate between RSEmulate 500 with CitectSCADA v6.1 through RSLinx OPC.  I have read several articles saying that it is possible but not how it is accomplished.  Everything that I read on Schneider Electric refers to newer versions of CitectSCADA, which I do not have.   If no one knows how to accomplish this does someone know where to download a newer version of CitectSCADA for free?  I have a demo key for up to the 2018 version.  This would allow me to use the walkthrough I have found.
  18. Is it possible to use FX3U-485ADP-MB as a serial port to send and receive user defined string/data to and from a computer? I have a FX3U-32M PLC and two FX3U-485ADP-MB adapters. I have been using PLC with one adapter as Modbus Master. Now i want to use both adapters, where one will be Modbus Master as usual and the other I want to use to send and receive data to and from computer terminal (Example - Realterm). I have a third party 232/485 converter which works really well. Lets me just describe my requirement straight forward. I want to display process parameters on a windows computer based user interface (UI) and also set some variables in PLC from the same UI. The UI has access to serial ports of computer.

Thanks
  20. Not able to establish DDE connection

    Good day to all, I am trying to establish DDE communication between my PLC (1769-L23ER) and MS Access via RSLinx Classic Gateway (3.9) over Windows Server 2012 R2.  On my developing PC (Windows 7), there isn't any issue at all. But when I port the codes over to Windows Server 2012 R2, MS Access is not able to establish DDE communications with the PLC.  I was wondering what went wrong. The error message from MS Access is "MS Access can't find the specified application and topic because it can't open the DDE channel, err.Number is 282. The code for getting the channel is as follow OpenRSLinx = Application.DDEInitiate("RSLinx","PLC-D") I was wondering was there anything I have miss out. eg. Configuration of the server, path settings, etc.. Any help is welcome. TIA Cheers CY

  22. Hi guys, I am trying to connect AB compactlogix 1769-L30ER through Ethernet cable to my laptop. I use Rslinx version 3.9 When I enter IP address it can find the CPU without any problem but it does not show the I/O. When I check the driver diagnostic, it says: Can't set port type to 288: no harmony object for this Ethernet I should mention that my OS is windows 7 and I turned off firewall as well. So, what does it mean and how I can get rid of this message? Thanks
  23. Hello All, What are the methods to get the monitoring data from A series PLC? I know its not supported any more, interface modules are not available...,    So the basically,   If I want to write customer software (may be embedded) what is the protocol I need to follow? I am connected to CPU unit by the way, there is no other modules except few digital and analog interfaces on PLC. Thank you in advance for your direction, direction in any way would help!
  24. RSLinx pc transfer question

    I have a customer who had a PC with an RSLinx Classic installation die.  The RSLinx was being used as an OPC server to collect information from a PLC5/25 through a 1784-PKXT DH+ connection and serve the data to an Automation Direct Lookout Direct HMI program on the PC.   We have a new PC set back up and the customer was able to have the hard drive recovered.  I am trying to get their system back up an on line.   After I install RSLinx, can I copy the files (harmony project, if I remember correctly) from the recovered hard drive into the new PC and have everything work?  or will I need to completely re-set up the OPC server?  I really doubt that they had used the backup utility.  But if they did, what file extension and location should I look in?
  25. Hi, I've been working with RSLogix 500, today i found that i was unable to connect to Micrologix PLC because in the RSLinx the Driver Ethernet IP that was configured to communicate whit PLC appears with a Red Cross. Yesterday everything was working. I've installed an antivirus software, i supposed the reason was the antivirus, but i've tried on configs and even uninstalling it, and RSLinx seems that can't reconigze the ethernet adapter (guess that means red cross) RSLinx 3.51 CPR 9 SR 5.1 RSLogix 500 Pro 9.0 Windows 7 Ultimate 32 bits Could you, provide to me some guidelines to solve this, or if somebody has had this problem, could share the solution? thanks in advance
