  1. Hi Everyone,I have a customer that needs a CQM1H (CPU51) replaced. They purchased the processor new-old-stock from a source they found online. It arrived in the original packaging and had the safety label around the top of the unit, so it seems that it is as advertised and no need to suspect that it would have problems. I purchased secondhand, a power supply to attach to it and program it from the bench instead of in the machine. The customer also provided me with an SD card containing the project file(s) for the machine. I am able to load the project in CX-ONE (running on Win 7) just fine. My computer has a native serial port (COM1) and I built a programming cable to work with the DB9 peripheral port according to a diagram I found online.The processor powers up right away with the ERR/ALM continuously on. No other LEDs came on initially, and after a bit of playing around with communications settings, I finally landed the right protocol and my computer seemed to identify the processor correctly. I compiled the source and attempted a transfer to the PLC. I got some failed message (or maybe messages) at the end of the transfer. It did seem to send all of the binary code, it just ended with an error message that I unfortunately didn't write down or grab a screenshot.Anyway, what I have now is a PLC processor with the ERR/ALM LED on always, I've never seen it in RUN mode, and now after the programming attempt, I'm seeing the COMM LED strobing at about a .5sec frequency (with or without a cable attached to the peripheral port), AND I cannot get CX-Programmer to again acknowledge the processor anymore. I'd like to reset this back to the way it arrived to me, but can't figure out how to make that happen offline. The DIP switches don't seem to cause that effect. I should say also that the DIP switch settings are all OFF except 3 and 7.Any help is much appreciated!Thanks,John  

  2. Help with wiring diagram

    LuisGonzalez posted a topic in Control Panel Building

    Hello,   I'm working on a project that involves using a 1734-AENT remote IO module. In this project, I need to configure analog inputs, digital inputs, and digital outputs.   Since I'm new to this field and have limited experience, I'm looking for guidance in creating a wiring diagram.   If anyone in this community can provide assistance or perhaps share a basic wiring diagram template, I would greatly appreciate it. My primary focus is on generating the wiring diagram itself.   Thank you for any help you can offer.
  3. I have been trying with an Ethernet cable and a 1747-pic i am 100% sure there is user error need to download a program into the PanelView i have the correct software rslinx and panelbuilder32 help I'm trying to learn
  4.  Hey guys I'm trying to get a older (windows 7) laptop full of A-B software up and running for my company. Like may companies, we have been reorganized and the person who bought the software under another company name no longer "owns" this company computer. Long story short, I'm having an RSLinx fault "RSLinx communication server has stopped working". I do not have the original discs or software key number information.   I can pull up the PLC software, hook up to a PLC using the DF1 comms, auto configure and detect the PLCs/panelviews in linx, so everthing, so the ports and cables seem ok to that point. But when I try to go online, or upload I get this fault. Is this an easy fix?   Will I need to reload linx 2.59 (no longer available), or could I download the free RSLinx Lite and communicate through that? I tried to download newer RSLinx classic through my Rockwell account, but Rockwell asks for information I do not have, like original purchasers name and/or Key numbers. I typed in the original company name, but there is a mismatch with Rockwell, who know what info they may have used?  I'd hate to toss all of this software away (RSLogix500, RSLogix5, Studio 5000, Factory View, Panelbuilder, ect... ) because RSlinx has some problem. My company no longer supports this old laptop, and rockwell is reluctant to help. This is really used as a programmer tool, not really a useable business laptop anymore.  I also dont know the legal or copyright issues, or if Rockwell considers my company a continuation of the original owner?? I'm in engineering, not the legal dept. I certainly dont want to stir the pot if I don't have to. LOL

  5. Crouzet Millenium 3

    NFAGEN posted a topic in Other PLCs

    Recently had to get a program out of a millenium 3 plc which I had programmed a few years ago but the cable would not connect.The only difference this time ,as my laptop no longer had a rs232 port,was the use of a USB to rs232 converter. Having trawled the web I managed to find the circuit of the interface cable below. It looks like the signal from the computer uses the negative going part of the pulses which aren't present on most usb to rs232 converters. Is this correct?
  6. Hi all, I'm new to Allen Bradley but have some experience with TIA/STEP 7 - not that it relates to this issue! We have 2 side by side systems but running a SLC 5/05 CPU, with the same program but different IP addresses, connected via a network switch. All has been fine until both were power cycled - system 1 CPU program has dropped but not system 2? The IP address for system 1 has been reset and can't be pinged from either the switch (but 2 can) or directly connected to the PLC port. Steps I have carried out as below, so would appreciate anyone skimming over and pointing out where I've gone wrong/something else to try; - Used BOOT P DHCP tool directly connected to system 1 plc, add relation assign original IP address, click Disable BOOT P. - Attempt to ping (after changing laptop IP to same loop but different node) = no connection - same cable used to connect to switch and ping system 2 which worked so cable and adaptor settings good. -not going to help with the immediate problem but battery swapped out for new on CPU. Any assistance and advice appreciated!
  7. Hi and thanks for youre time  I am a newbie trying to connect to a 1769-L30ERMS using an Ethernet cable. I am using Studio 5000 and RSLinx Classic lite for programming and communication. However Studio 5000 and RSLinx Classic lite are installed on av virtual machine using VMware.  So my problem is two fold. Connect the VM so that it reads from the real computers ethernet port Find and communicate with the PLC from the VM There are guides on how these problems are addressed seperatly. For example https://www.youtube.com/watch?v=JdArYVceO1I and https://www.youtube.com/watch?v=ERLTvcBBK_w however I have not been able to get them to work together. So I was wondering if you, the sages of PLC programming might have some tips or trix that I could test or perhaps even a guide for how to do? Mvh Eric
  8. Hello I am not sure if anyone know how to select cable cross section for 5KW AC motor? Thank you

  10. Hello everyone, I am a newbie with PLC. I have a Micrologix 1000. The last time I connected with RSLinx easy, however, I change it to DH485 (I do not remember exactly). And now I can not connect it to RSLinx, I tried many times for all types of drivers. Please help me. Thank you very much.
  11. We have an SLC 5/05 on our automation network, one of several SLC 5/05 processors on site.  It functions perfectly well and no ethernet messaging issues or SCADA drop outs.  The difficulty I am experiencing with it is when I am required to fault diagnose it takes a very long time to get online to it with our laptop running RSLogix500.  It sometimes takes as long as 10 minutes.  It makes no difference whether I use the Ethernet devices or the EtherNet/IP Driver in RSLinx, it nearly always takes an age which is frustrating in a breakdown situation.  I don't ever experience these long wait times connecting to any other of the SLC 5/05 controllers or any other controllers for that matter.  Once I am connected to the problematic controller I don't experience any issues, it's just the initial time getting online.  I try to leave the laptop permanently connected to it to avoid the long wait time to connect.  When I open RSLogix500, select Comms, Who Active Go Online, Ethernet devices driver, I can see that the problematic 5/05 has Active as its Status whereas the other 5/05 processors have Remote Run as their status.  Please can anyone advise as to any possible program parameters, RSLinx settings or hardware faults I should be looking for?  I have considered it could be a network problem but I'm unsure about this given how the processor performs well in every other regard.

  12. PLC Scan of Rung

    LEMON FOAM posted a topic in Mitsubishi

    According to picture 1, ''Piston A moves to the right. After the set time, K = 4, the normally closed timer T450 contacts open and the normally open timer T450 contacts close.'' But according to picture 2 After the power flow from Left power rail to right power rail, it should directly go to 2nd rung and cause the normally open timer T450 contacts to close only right? but why it will go back 1st rung and cause the normally closed timer T450 contacts to open? Anybody can help explain me regarding this. Thank You in advance
  13. Hi! I'm using RSLinx Classic, RSLogix Micro English and RSLogix Emulate 500 to emulate a Micrologix 1100 Series B. I'm able to run, program and simulate different input and output with the emulated PLC. Everything works fine. My problem is that I'm writing a program using the nodePCCC library (https://github.com/plcpeople/nodepccc) and I'm not able to connect to the emulated PLC using the address 127.0.0.1 and the port 44818. I tried  running 'netstat -a' on Power Shell and I found out that the port 44818 is not being used.  Could someone help me identify what I'm doing wrong?
  14. Hi All, How can I collect the information provided through RSLinx in a ControlNet network, specifically on the Station Diagnostics Contronet devices? My idea is to generate some statistics errors and avoid some network errors failures.

  18. FX-2NC-32MT Battery & Communication Cable

    Sohel.ahmed.uk posted a topic in Mitsubishi

    Hi, FX-2NC-32MT PLC need to change Battery, Can you please tell me the battery model no? Which communication cable require  for FX-2NC-32MT PLC upload or download program? Thanks & Regards Sohel Ahmed
  19. Hi, I have an old TSX 47 30 that has an I / O fault (red led on) green led on run and plc stopped. I'm writing to see if you can help me to establish communication and achieve the download of the program. I do not have the communication cable or the PL7-3 software under OS 2. So far I have done searches on the schneider page, forums and all the links are lost or deactivated. I have read your answers in plc of the same series and I observe that a converter rs 232 to current loop is needed. In this case here in Venezuela it is difficult to get this converter, however I have observed the black box model 232 CL-E, CL050A and I think it can be useful. I also have an old toshiba laptop with windows xp with a native rs 232 port to avoid another converter and I could make the connection cable DB25-DB9 to the PLC. Now I would miss the procedure to make an OS / 2 bios and get the software or make a virtual machine in which case I require the appropriate software .. thanks for your help
  20. 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!
  21. 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
  22. 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 .
  23. I have been given a 1747-UIC to use..... someone has managed to snap the DB9 connector off of the soldered connections in the DB9 Plug. I have tried to deconstruct the plug but the cores had been pulled back too far and no longer showed where they connected to the plug. I have 5 wires red, brown, blue, violet, yellow, and a screen ? Does anyone know how I should connect them up to a DB9 plug

  25. 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 "111.111.111.111" into excel, run the macro, and have it fill in the components on the backplane below. 111.111.111.111 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
