  1. CP1L Unknown IP

    Hello. I have CP1L EM30 with unknown IP. I have tried to use "Direct Ethernet Connection" with "Network Browser" but with no success. I have manually set the ethernet IP4 address to 192.168.20.20 / 255.255.255.0 I've got error: "The OMRON Ethernet Direct Connection Manager service is starting in Safe Mode because Windows APIPA is enabled. (0x82020003)Omron.Cxmw.Modules.SystemLibrary.SysLibException" The PLC does NOT have default ip 192.168.250.1. What Can I do? Please help. Thanks. BR, Andrej.  
  2. Hi Team ,  I am new to MicroLogix 1400 , I wanted to decode following frame which i have already done , but am not able to crack how CRC is calculated in this frame , like the data sheet which i am referring for this shows about BCC calculation , which is only of 1 byte after end of frame , but i am getting 2 byte CRC value and that's not matching to any of the CRC standard format , please find the frame for the same .  Tx: 10 06 10 02 01 00 0F 00 FB 6F A3 FF A8 4F FF AC 51 FF AE 51 FF 9C 4F FF 94 51 FF 96 51 10 03 4B   Rx: 10 06 10 02 00 01 4F 00 FB 6F 00 00 00 00 00 00 00 FF FF 00 00 00 00 00 00 00 FF FF 10 03 BE 07

  4. GX Works 3 glitch?

    Hi all, I have a program I am editing in ladder mode It is getting quite large, nearly 30k steps now At some point after a continuous paste (I think) the editing has become glitchy If you try and change an item it inserts the new one and keeps the old one It puts in horizontal and vertical lines seemingly randomly which you have to play around to delete before conversion It is only this one program I tried editing on 2 pc's, no different I cant find anything in mitsubishi manual  Has anyone else had same issue? Thanks in advance  
  5. Hello, I'm a little experienced, a little new with (I hope) a fairly beginner question. I've got a customer that has a pre-existing HMI running a Factorytalk View SE - Network program.  The customer would like to make some changes to the HMI, and I feel pretty confident that I could do this; the only problem is I'm having difficulty connecting to their system and downloading a version of the program that I can edit. Almost every How to video and instructional PDF that I can find appears to start from the premise that I created the program and have an existing copy on my computer or am starting from scratch, but that is not the case.  I know the IP address of the Networked PC that is running the HMI and can ping it etc, but I do not know how to connect to it.  I even have a copy of almost all of the files that the PC is running from the customer, but do not have a file that I can open in FTView to edit or change then download; I think I'm missing the .cli file or somesuch? Do I have to be directly logged on to the PC or can I be on my programming laptop and connect via Ethernet->switch->PC (I think I need FactoryTalk Linx for that, which I have a licensed copy of)?  I know that Machine Edition requires a .mer file to be able to open and edit an HMI program, is the network edition the same? Any help would be greatly appreciated!
  6. Hello! I'm currently using NB designer v1.531 (Build 210511) and I'm having compilation errors. It states: Connecting... Connection Error PT HMI0 Compilation error! Cannot create pkg files! I'm have trouble understanding, what does this error mean? I'm not connecting to any HMI, I just want to compile the program and test it offline. The weirdest thing is that if i click "Compile" enough times, it will eventually compile, but this is really interrupting the workflow. Does anybody else have this issue?  
  7. S7 300

    Hallo, I have two operational S7 PLC's : 1 x  S7-300 and 1 x S7-1200. Both PLC's I want access in our internal netwerk, but S7-300 have only a MPI-connection and not a RJ45-connection (profibus) What can I do to access both in the same network ?
  8. Hello everyone, I want to use my own computer as plc. I have a molex brand SST-PB3-PCU SST card. I will connect my I/O modules to the profibus adapter, then I will connect the adapter to the SST card. Can Codesys see this SST card and if so how do I make the connection. I can connect this type of connection in the InControl (an old software) program that I used before.  Please Help Me!! The Board I use to connect the I/Os to the computer: SST-PB3-PCU  Profibus Adapter to which I connect I/Os: 1794-APB | Allen Bradley PROFIBUS Adapter Module My I/O Modules: Allen Bradley 1794-IB16 and 1794-OB16 My OS: Win10 64 bit Codesys Version: CODESYS V3.5 SP18 Patch 3
  9. Dear all, I'd like to get your support on the issue with OPC UA certificate. My OPC UA server has been built with Node.js. The PLC S7-1500 (firmware v2.9) acts as OPC UA client. It's working well without certificate but when I use certificate, there are 2 situations: 1. When connecting using "Online access" (as attachment) in the "OPCUA Communication >> Client interfaces", I can connect with certificate (after I export and copy the PLC's certificate to the trusted folder of the server). --> server is ok. 2. When coding and running with real PLC: can't connect, there is even no PLC's certificate on the rejected folder of the server and there is no any error, the Status of block "OPC UA Connect DB" is still 16#0000_0000. So, what I did with certificate in TIA Portal (V17) are: - Enable the Global security setting for certificate manager - Created (and tested) with both self-signed certificate and CA certificate for PLC - Added server's certificate to trusted list in "Certificate manager" of TIA Portal (also added to the "Certificate of the partner devices" in  Device config) - In "OPCUA Communication >> Client interfaces", chose the Security Mode/Policy and PLC's certificate (already tried with and without this setting) In my point of view, the problem is that the PLC received the certificate but somehow it didn't read correctly or didn't compare with the certificate in the trusted list because if the PLC does this step, it should send its certificate to (the rejected folder of) server. Could anyone help me to solve this issue? Thank you in advance.   [Update] 1.The PLC throw the error code 16#8016_0000 (BadCertificateHostNameInvalid/The HostName used to connect to a Server does not match a HostName in the Certificate - as I searched in google) but it's very quick so I could not see this behavior at the beginning. 2. I have tested with UA Expert, I can connect without any problem/warning. So, the high confidence that problem comes from PLC. ----------  Best regards, Danh Vo
  10. I would like to get some feedback or alternate suggestions in terms of monitoring a database connection. The attachment here shows the current programming for the DB_Connect function block which requires the Execute input to constantly be ON.  From what I can tell, if the connection is dropped - let's just say the Ethernet cable is unplugged - this input will still be on, and according to the function block, still connected. The Get1minClk is in place to continuously try establish this connection once powered on, but I cannot find any way to periodically check this connection without dropping it and reestablishing it.  My understanding is the _DBC_Status.Run only checks that the PLC service is running properly, but is there a way to monitor a heartbeat of the connection TO the database?  The only way I've found thus far is to drop the connection and reconnect.  But this would be detrimental to the system as it would possibly be reconnecting to the database while trying to write to out to it and hold up the show.  As it stands in the second image, the Ethernet cable is unplugged, but the connection shows no errors. Thanks and happy Friday! -K  
  11. Hi, So I have a problem, that BootP DHCP server doesn't find my 1734 AENTR series B and so I can't assign IP address to it. Been trying many things. Any advice? I'm new to AB and I guess it may be a really easy thing but so far I didn't find a solution. 
  12. 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.

  13. Hello, I've been using Mitsubishi and Omron systems separately (in their own environment), and I am fairly new when it comes to connecting these two brands together(plc and hmi). I've been scouring the net for wiring diagrams for the cable connections and also the parameters to be set for a successful communication between those two components. can anyone point me at the right direction as everything I've tried so far has been a failed attempt of making these two communicate. here are the parts and my current settings if this helps: FX3U-64M FX3U-232-BD NB5Q-TW00B or better yet, is there a proper cable that I need to buy for this to work?
  14. Hello I use emulator to test and run my program . Currently ,I am not able to make communication between Rslinx and (RSLOGIC 5000 & Emulator). I configure my drivers from RSLINX but it does not configure from RSLOGIC 5000. I am not sure anyone know how to solve the problem?
  15. Hi all, currently I'm using NX1P2 PLC for my project. So I'm just using it to transfer data from PLC to my PC but I faced 1 major problem right now which is the connection. I have few experience working on PLC but this time I faced an issue which I don't know how to solve it. So the problem here is, my NX1P2 can't connect stable to my my PLC, initially I thought it was the cable problem, after I changed several cable it's still the same, so I thought it was my ethernet port problem but I can connect it to the internet and also Delta PLC, at last I thought it was PLC problem so I connected it to my colleague PC, they got a stable connection and able to program it. My ethernet keep on displaying "Enabled > Identifying > Unplugged", I check my Ethernet port, it using Intel(R) Ethernet Connection (6) I219-V. Tried to solve it for few days already, anyone faced this problem before? 
  16. Is their any method like virtual port adding to advanced HMI and cx programmer to view input and output from advanced HMI to Cx-programmer.?    
  17. I have an SLC 5/03 that Im trying to get the program from. I have a 1747-uic. Im not getting anything to show up in rslinx and I suspect the channel 0 is configured for ASCII because theres an HMI plugged into it. Also the rj45 connection is broken because someone used a crossover ethernet cable...lol. is my best bet to try and fix/replace the 1747-uic? I have an offline copy of a program from a different machine that uses a 'similar' setup and the CH.0 -System is configured for DF1 full duplex,19200,CRC and CH.0 - user is ASCII 19200 baud. Any Ideas? I was using the 3 wire db9 connector running from the HMI to the PLC. I unplugged it from the HMI and used it with the 1747, Should I use a standard DB9 cable with a null modem adapter?
  18. Hi there, I am having issues connecting my computer to our SLC 5/02. We have a genuine Allen Bradley 1747-UIC USB to DH485 adaptor, I have read into it a fair bit and have tried many different things. I have removed pin 3 configurations from the ethernet (DH485) as advised previously.. I have tried many drivers to get it to work to no prevail. I cant even change the CPU over to a 5/03 as I cant guarantee the program we have a copy of is the exact one in the CPU, therefore I cant just change to a different unit and establish comms that way. Does anyone have a step by step guide to connecting the 1747-UIC to the PLC? Many youtube clips dont seem to work for me like they do in the videos.   Thanks a lot in advance if you can help!
  19. I need to connect a A/B 5370 or 1756 to a PC and communicate over TCP/IP and be able to read and write input/outputs. What features does A/B provide? I would prefer to write in C/C++ but can also consider Structured Text - if it supports the standard socket type functions.

  21. Hello All,  Am a bit new to practical PLC applications. I was trying to configure a Phoenix Contact I/O module (1452916) on a MicroLogix 1100 PLC but it kept faulting out with the fault light RED. It would say "Major Error Halt S:1/13". The error description says I/O mismatch. The error code is 187h (see attachment). The Phoenix module has a cable with 19 pin positions for the 8 input. I connected the pin 17 and 18 to 24 volts and  0 volts respectively. Then because I was using input 5 I connected the pink wire to PLC input (I/1) 24volts and the White/Yellow wire to the PLC common.  On the I/O configuration on RSLogix 500, I used "Other" ( See attachment) but did not know the vendor details. Could anyone help me with the steps on how to communicate with the module? I have also attached the PLC program I was running. Thanks        
  22. Hi dears i have one client and 21 servers i want to eatablish a connection between this client and servers is there limitation for access servers? i read that one client can access to 12 servers only is it true? what is the best way to connect this client to 21 servers? best regards
  23. Genst,   Could You please advise how can I connect to CJ1M CPU12 - shown in attached picture. DB9 port is used for communication with remote input/outpus rack.

I want to connect to CX-programmer to be able to online troubleshoot PLc program.   thanks in advance. tomasz  
  24. Janitza UMG96RM RS485 Bus

    Dear All.     i'm a new user for Janitza. and i have issue related to RS485 actually, not to Janitza itself. i have one device (UMG 96RM), where there is only RS485 (2 pin only), no RS232, no USB, No Ethernet port. i'm trying simply to connect the device to the PC, via (USB to RS485) convertor, but i'm not able to do it. for me, this is the first time i'm see (RS485 2 Pins), usually there is Ground signal also. anyway, could you please somebody help how to connect? shall i add a pull up & pull down resistors at the device? and what is the power supply i must use? noting that, i tried many things, but still nothing happened.   Appreciate if somebody can help   Best regards.
