  1. communication with PC

    I have a project where I have to read I/O, and potentially initiate programs on the Mitsubishi PLC. Seems I can use the Melsec Protocol but I have some difficulty getting started. I can communicate via Ethernet using GXWorks 2 so hardware-wise there shouldn't be anything wrong. I'm using QJ71E71, Q06HCPU, QX42, etc. Initially I open a UDP socket to the correct IP address and port (copy the port from GXWorks) and attempt to issue a request 3E/Binary, specifying the network, PC, Module IO, and station and it always times out. Is there any source code that just does a basic read of a memory location? I'm using C++ but I should be able to understand any code sample in VB, C, C#, or others. Also, is there any issue with multiple connections to the PLCs. Right now I quit GXWorks before I test but is this necessary. Thanks, Jeff
  2. It's another BOOTP post! I know you're all as excited as I am, so lets get started. But seriously, I'm trying to disable BOOTP on the built in Ethernet ports, not on an Ethernet module. I specifically say disable because BOOTP successfully assigns the IP address to my Compact Logix, however I still need to disable BOOTP to make it a static IP address rather than a dynamic IP address. I'm going to list everything that I have tried, so that anyone with the same issue can have an all-in-one-place reference. (Because there's a number of forum posts and other information for this topic on the internet, with many different suggestions) If I see different ideas/suggestions in other places, I can edit them into this post. Things I have tried: (and you should try if you have this issue) Disabling all firewalls, (For me: Windows/Avast) Disabling all other network adaptors. (Wifi especially, but any and all adaptors you are not using for the setup) Using a different laptop/operating system: (My current laptop runs windows 8.1 and uses a Linksys usb to Ethernet device to talk to the PLC, I tried a laptop running windows 7 which communicated using a built in Ethernet port) Lastly: Try to use all available methods to disable it. For me, that would be: BOOTP standalone server, RSLinx, (Trying to use both USB and Ethernet connections) and finally RSLogix. (Actually, only Ethernet modules have a "disable BOOTP" checkbox built into RSLogix, so that is not an option for me.) [If you have an Ethernet module, go to port configuration in RSLogix and uncheck the "enable BOOTP" checkbox] Anyway, RSLinx Classic (version 3.71) and BOOTP Standalone server (version 2.32) are each coming back with an error when I try to disable BOOTP. I'll attach a .jpg of some screenshots, and some Wireshark save files to show what I mean. In the RSLinx Wireshark file, it shows a "privilege violation" packet being sent from the PLC to the laptop towards the end of the exchange, but I'm not sure what privileges the laptop needs/doesn't have. For the wireshark files: I cleared everything happening before I try to send the command, so that there isn't a ton to search through. As far as timing of the wireshark files go: I start recording traffic, send the disable command (by clicking the disable BOOTP/DHCP button on BOOTP server or "apply" on RSLinx) then I stop recording traffic once I get the error message. So, the captured packets should be just the attempt to disable BOOTP and that's about it. I am sorry that I the pictures are strung together using paint, but I don't have photoshop on my work computer so it's the best I have. Any suggestions/help would be appreciated! (Regardless of whether they are suggestions for me, or suggestions that I may have missed intended for anyone with this problem.) Thank you for your time. Edit: I had the attached pictures open in paint/photo viewer, sorry that they look bad in the forum picture viewer. BOOTP_wireshark.pcapng rs_linx_USB_wireshark.pcapng rs_linx_wireshark.pcapng
  3. Hi, i have to connect few PLC on the same subnet, there are 3 Omron CJ2M and 1 AB L33ERM/A, the connection should send some words between one of these Omron PLC to the AB   I've tried using the "Explicit Messaging" but i cannot send the data, i only receive the error "514" and nothing more, what can i try?
  4. Ethernet/IP.  I am new to AB and looking for the smallest (cheapest) AB PLC that would support Ethernet/IP  network devices .   Can someone point me to the PLC that would fit this?   Also which software would be needed for programming?
  5. I have an application I am currently working on where I have a single AB ControlLogix PLC that needs to read data from 12+ Omron CJ2M PLCs.  The Omron PLCs don't need to read any data from the AB.   I have tried several things including the generic .eds file from Omron and the instructions in the document I found on this site:  Omron CJ2 to Rockwell ControlLogix Ethernet/IP Datalink.  The generic .eds file gave me a D6 error on the Omron side and after talking to support it does not seem like the correct path.   When I tried following the instructions for the datalink I ran into several issues.  The first issue was that after configuring my network in the Omron software upon trying to load it I got a unit mismatch message for the 1756-EN2T, the .eds file I have is for a 1765-EN2T but the card shows as a 1756-EN2T/D, so I am concerned that could cause an issue...that being said I can't find any .eds file specifically for the /D revision.  The next thing I noticed was that there doesn't seem to be be a way to link the produced data from the Omron to the AB, the Omron configuration software with the AB .eds files loaded only gave me the option to send data to the Omron which we do not need to do.  I created a generic Ethernet module in my RSLogix program for the Omron PLC and then created a consumed tag and linked that to the module but I do not see where I set up the link on the Omron side for that, so how does it know what addresses to read?? Any help would be greatly appreciated!!!! Thank you!

  12. HOSTLINK Problem

     I  am doing  a data collection from  OMRON PLC CP1L through MS excel VBA  use API function. The connection was setuped correct (I think)both in PLC and PC side. The trick things is   when PLC have USB cable connected  the data  was send to PLC and can get feedback through RS232 in normal.(I use portmon moniter the progress,and I can see the data (C-command ).But when I get the USB cable removed  ,The PLC can not get any reponse back.Dose any of you have met that  before?

  17. I have siemens hmi TP177B PN/DP on hand and I want to get the existing program on the hmi devices via Ethernet connection on my simatic field PG but I was unable to have a connection on the hmi via Ethernet, I have already set my PG interface to TCP/IP auto. And I also tried to ping the hmi address (192.168.0.4) which is set on the hmi device, but still its unreachable.
  18. Hello, I am new to the connected components workbench software. I am working with an AB panelview component Hmi and would like to create numeric buttons to load integers into user variables in a schnieder LMD servo motor. The motor uses Modbus TCP to communicate. It appears that if I click on the numeric buttons properties there is a "Write Tag" of which you can use some default tags or create a new one. I am assuming that I need to create a new one with the motor's addressing but I'm not quite sure how to accomplish this. Any help would be much appreciated!!! Thanks, Steve   
  19. S7-300 MPI & Ethernet connection

    Hey all,   long time without posting, I don't know if i'm writing in the right place.   I have some old PLCs S7-300 ( and a couple of S7-200) that I would connect to the same general network in order to see all data from a general SCADA (I'm thinking about Ignition but could be WinCC etc).   First problem is that few of them don't have an Ethernet Card (still old MPI) and I'm searching for a converter. I've found something on internet that I could install, probably no big issues on this side.   Main problem is that others have an Ethernet connection but they are programmed to work on their own network (indipendent machine) and I couldn't change all IP addresses. I need probably a Gateway (eWon??) but I would understand better how it works. Any suggestion?   Thank you in advance for your help!!
  20. 1746-IQ32T

    Can anybody help me with the pinout diagram of 1762-IQ32T with 1492 I have seen the manual but it doesn't exactly tell which should be the first input and which should be the second 
  21. Hello. I'm strugeling to setup communication betwen NS5-TQ11B-V2 and CJ1M ETN via Internet/IP. I have configured PLC: IP: 192.168.1.1 (Node Nr:1) I have configured HMI: IP:192.168.1.2 (Node Nr:2) But I can't get it to work. I See flashing leds on PLC (RD / SD) so the PLC must be answering. But on display I get Time-out error... What am I doing wrong?   Best regards.
  22. Let me try to explain this correctly..  I have a machine built and coded in Japan, so while I know 90% of the code and functions there are certain parts of the code I have never touched.    Today i started getting an error that is commented as E-Net, so I am assuming its an ETH I/O issue.. but the device is something I have never seen. U1C\G20480  Can someone explain to me what this device is or how it is used? 
  23. Trying to programmatically reset the Ethernet port on a 5/20E.  It is talking successfully to a 3rd party PLC with their "message block".  However if the connection breaks (i.e. Ethernet cable disconnect, put one of the PLCs in stop mode, etc.), how can I reset the Ethernet port on the PLC5 via looking at a process status tag?  Right now the only way to get it to work again, is to both power cycle the PLC5 and stop and restart the message block in the 3rd party PLC.   Didn't get info from RA when I contacted their tech support.      
  24. Hello all. Long time forum reader, first time forum poster. I'm in a controls role (first job out of college) and this has had me stumped for a while: We have our PLCs connected to our plant network through QJ71E71-100 cards. We use them for data collection/applications with OPC. For that purpose, it works fine.  We also use the "Station No. <-> IP Information" settings with conjunction with JP.READ and JP.WRITE to send information between some PLCs through the plant network, it also works fine. For the PLCs that we do not use the "Station No. <-> IP Information", remote connecting works well, no problem. The problem we have is we want to connect to the PLCs remotely for troubleshooting/monitoring. Any PLC that use JP.READ / JP.WRITE commands and has the "Station No. <-> IP Information" setup (Table Exchange System), we can not connect to remotely. It gives the standard error message as if we are connecting to something that doesn't exist. This has been happening for years (same issue with GX Developer). We have tried new Ethernet cards with newer firmware. We have verified that we are not trying to use an occupied station number, we are using the correct network. Mitsubishi Reps have been stumped and point to our IS department as being the issue.  We have talked to our IS department about this with our Mitsubishi Reps, our switches/hubs have the same configurations throughout the plant (by the way other lines don't have this trouble, even though they use similar commands) I've looked at buffer memory settings of other lines to see if there are any differences between ours, and theirs and there were none. I've attached screenshots of the error message that we get when trying to connect to one of these PLCs. Does anyone have any insight on this problem?  If anyone needs more information, feel free to respond to the topic. Also greetings all, I've learned a lot for this forum in general.   
  25. Hello, I am trying to connect an OMRON CMP1-30CDR-A-V1 to my PC. I used a CQM1-CIF02 cable which I connected to RS232-USB converter and then to my laptop. Is this the right way to do it? I have seen on the OMRON website the attached diagram. Should we use that device or an RS232-USB converter will be enough? Also. I tired to use a PC with RS232 port directly but it also failed. Regards,
