  1. 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.
  2. Addressing I/O

    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
  3. 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!
  4. 502 port error

    Hi  i am trying to connect to omron plc (cj2m ) using modbus tcp/ip , by using the port 502 i  get an error saying that the port can't be reached is there any method to fix that or change the port number ?   thank you

  6. I need some help and advice communicating between an Omron PLC and a Keyence KV-5500. My system typically uses an Omron CJ2M-CPU34 which comes equipped with the built in Ethernet IP port.  My customer is insisting that we change the CPU in our system to a CJ2H-CPU66-EIP in order to communicate with the Keyence KV-5500.  They have not been able to detail why their communications require the CJ2H, they just say they will be using Ethernet TAG communication and for this they need us to change the CPU. Has anyone successfully established communicated between the Omron PLCs and the Keyence?  If so how did you do it and which CPU did you use?  Is there an .eds file available for the Keyence CPU? Please help!!! They will be visiting from halfway around the globe to test communications in January so I want to be prepared!
  7. Hello, recently I tried to hook up a new CJ2M-CPU31 (built-in EIP Port) with a NS10-TV01-V2, which has an Ethernet/IP connection also. I made the simple setting as usual : 1. PLC, IP Address 192.168.250.1, Sub 255.255.255.0, FINS Node 1, no change to FINS/UDP parameter (Auto Dynamic Generation) 2. HMI, IP Address 192.168.250.2, Sub 255.255.255.0, FINS Node 2, Register the Host as EIP, SYSMAC-CJ2 mode with the PLC IP, Disables the Serial Port For some reason, there is no communication between NS and CJ2M (timeout error always occurs). I tried to re-register the Host as FINS, set the Node to 1, and also with no avail. I did try to connect the NS to a CP1L-EM with FINS Comm. and it works fine. Anything I did miss? Thanks in advance
  8. CJ2M serial communication

    Hi! I'm trying to connect Omron plc CJ2M cpu11 (photo below) with Weintek touch panel. I've made proper cable, and I'm trying to establish communication between these two devices. I've wrote a script in Weintek's program, that sends and receives via serial port, rs232. Also, I've used example for serial communication in CX-Programmer, that you can see in attached files. I'm trying only to toggle one W adress using hmi. That sounds simple, but still, I'm not able to make plc and hmi to talk with each other. What I'm doing wrong?
  9. CJ2M CPU32 SERIAL COMMUNICATION ISSUE

    Hi, I am having an issue with Omron CJ2m Cpu32 serial communication. I'm not receiving the data from pc to plc. sometimes during the production. When I recycle the power its working fine. Is there any Flag to reset the Serial port and clear the buffer on Cj2m VPU32. I contacted tech support and they told me to use A526.00n to clear the port. But I think A528.00 is not for CJ2m cpu32. I'm new to Omron programming and serial communication any reply or response would be helpful. thanks in advance.
  10. Hi. My goal is to communicate from a Wago 750-881 Controller to CJ2M With ETN21 on Modbus UDP. I can only find Modbus TCP function Blocks but would prefer UDP. Does it excist ? Cheers. WagoGrim
  11. Hello everybody, I have CJ2M-CPU35 connected to couple of devices over ethernet IP. I would like to know which bits in CIO area (25 words for built-in E.Net port starting at 1500) gives me the status of Individual nodes (i.e. connected or not connected) Tried to go through W465 but there is a lot of information and I'm getting confused with built-in port, additional E.net IP units, Fins TCP, Fins UDP etc.
  12. Hi All. I have a problem with D memory area. I have PLC CJ2M with ID211(DC input), ID211, OC211 (Relay output), OD212 (Transistor output) on the CPU rack. When I turn on all outputs in the OC211, all my datas in the D memory area is set to 0. What could be the problem? plc_project.zip
