  1. Hello, I am using an NJ301 PLC with an NA series HMI. I am communicating to the PLC via FINS protocol using the DotNet FINS UDP application by Jay Anthony found under the downloads section. I am finding that when I write a string to an address, the bytes order are reversed. For example,  I am writing the string 'Test' to variable 'FINS_String', which is a String data type at memory address D20. My FINS command is the following: 010282001400000254657374 0102: Write 82: Data Memory 001400: Address 20 0002: Write 2 words 54: T 65: e 73: s 74: t The value that appears on the HMI and in the watch window is 'eTts'. If I write 65547473 (eTts) as my command, it appears correctly as 'Test' on my HMI. I debugged the application and I see that the byte array is being sent in the correct order, so I'm not sure what the matter is. I can't imagine that to pass a string through FINS protocol the hex values need to be switched every time.  Any help would be appreciated. Thank you for your time.

OD211(1pcs) -> ID231 (1pcs) after the setting and upload program , warning appear for the image its on attachment. so if i want this system to run do i need to buy expansion rack or there is another solution ? Best Regard

  8. CJ2M CPU - Omron FINS Vs Omron EIP

    JayPrakashTiwari posted a topic in CX-Programmer

    I want to implement Omron CIP, which communicates with CJ2M CPU35 Controllers across an Ethernet/IP network using the Common Industrial Protocol (CIP). Which commands they will use? FINS? or some other commands? Can someone help me to understand the protocol or command structure which can be used to implement Omron CIP (Ethernet/IP)?
  9. Hello, My quest is to make a memory card, which I can just put into my PLC on the field and load all program and options etc to my plc. Now i found the official omron guide about it but its not good at all... For example is does not explain that how i need to transfer the H and D memory part to the plc, and that not all network settings are being copied if im not careful.   But my question is: is it possible to make this backup memory card without having the actual plc? Because the process is done in memory card window, which is only available if you are online. So basicly i have to get all the plc rack parts to make this work? I tried with the simulator but ofc it is not working.   Someone mentioned me that it is possible he heard from someone but no one actually knows how to. And there is nothing in the omron manual as i see.
  10. Hi, I am working on a project that requires connecting an EtherCAT network and an Ethernet/IP network to the built in ports of the NJ controller. I have been able to setup the EtherCAT network in Sysmac Studio, but I am struggling with the Ethernet /IP setup in Sysmac Studio. For the Ethernet network I have to setup the Motoman DX200 and a Cognex In-Sight 7000, as well a NA HMI which I was able to figure out and have it setup in Sysmac Studio. I have the EDS files for both Motoman and Cognex and the are installed in Sysmac Studio. I am a confused about what to put in the target variable and the originator variable, as well how can I connect these to my Global variables?

  11. Addressing I/O

    MrEngineer posted a topic in CX-Programmer

    Hello Guys and Girls, I am new to Omron and I am just setting up a new project. I have populated my rack in the (I/O Unit And Table Setup) but how do I address the physical inputs and outputs?  I started to populate the symbols area but when the inputs I had typed in 3.0 - 3.15 (16 inputs) It wouldnt let me populate the other 16 inputs (3.16 - 3.31) of the 32 input card?  What am I doing wrong? any help will be much appreciated. Many thanks in advance. MrEngineer

  12. PLC to PLC Wireless Communication

    innoaloe posted a topic in Omron

    Hello lads, I wanna ask if anyone have attempted to connect two or more Omron PLC via wireless before, and if so how you manage that? My understanding so far is that one PLC should be connected by Ethernet Cable to a Wireless Access Point, and the other one should connected to a Wireless Client. After that the Client tries to automatically connect to the Access Point, then both PLC can communicate via FINS/UDP or FINS/TCP easily. I want to test out two PLC for now, but on actual setup there might be 10 Wireless Clients Any thoughts? Thanks in advance
  13. I an seeking guidance on how to link two mitsubishi PLC over Ethernet and have them pass bits/words between them.  PLC 1, Q03UDV built in port  ---- GXWorks 2 v1.54N   192.168.1.39  (QJ71 in slot 1 is also available if req'd) PLC2, Q02H with a QJ71 Ethernet card in slot 2.  Same GXworks2   192.168.1.35   I know with a modbus or CCLink setup, there is a place to declare the buffer > X/Y parameters, but i have found no such parameters for the ethernet connections. I found 1 document describing the JP.Send instructions but I have not been able to get that to work from the example.    any help would be greatly appreciated.     

  14. communication with PC

    Rocinante8 posted a topic in Mitsubishi

    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
  15. 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
  16. 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?
  17. 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?

  20. Hello, I am new to the Beckhoff PLC systems and PROFINET. For one of the applications I am trying to connect ETHERCAT module to the PROFINET Controller which is in turm connected to IO modules. I am using the following modules: ETHERCAT coupler EK1100,EL6631 (Controller), EL6631(Device) --> EL6631(Controller)*,EL1008 (Input module) The connection between EL6631(Device) --> EL6631(Controller)* is via Ethernet cable. I am not able to configure the connection in the above mentioned fashion. Please let me know if this is a valid configuration? Is there any simpler way to achive this. And I am using the TwinCAT3 software on my PC.   Thanksk in advance :)
  21. 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!

  25. IFIX Scada communication issues

    krysmberg posted a topic in GE

    I am new to ifix, I am having an issue, I am unable to receive any information, after attempting to fix the fact that the view was only pulling half the data I lost it all, I had a back up saved, but it didn't work on restoring communication, I was getting a cannot connect to node error, but I have fixed that, now all I am getting is question marks. essentially I believe that I have two standalone computers with the ifix software and the communicate directly with various plcs that share information across, either a ring topology or full connected. so the computer I have that is working is setup with scada and the database and MB1 with no network support, the one that is not working is set up the same, my cable connection is a usb to Ethernet and im communicating with a Comm port on the computer. I've tried different comm ports, even contacted GE, they were suppose to have someone call me back but no one has yet. Can anyone give me an idea of what I've got wrong here?
