@IO_Rack, That is what I needed confirmation on. It was not clear to me if CJ EIP Coupler Unit existed, the Omron Rep confused me on this matter. It does look like the NJ controllers support the same rack configuration as the CJ series. If I understand things correctly, I should just be able to swap out the CJ2 controller and Slot in a NJ controller.   If I want to do remote IO then I need to use the NX Io Platform, (which can talk to the CJ and NJ PLC's)

We do want to move away from FINS. If I understand you correctly, Inside of Network configurator (Somewhere) I can create data blocks for the EIP21 card, such that I can use it as a remote rack. Is there any documentation surrounding this? I have only used network configurator to link Ethernet devices together, as the blocks are normally handled by the EDS for something like a VSD, or Sysmac, if you are using NX Remote IO

I happy to use any card, I am just not sure on the particulars of the configuration. When using the NX remote IO make to determine the Input and Output sizes to then use in Network configurator. But I am not seeing what the equivalent is on the CJ platform. How do I set up the remote rack, what software am I using. Thanks

Has any configured a remote ethernet rack using the CJ Platform? Scenario: Local Rack: PSU + PLC + Ethernet Card Remote Rack: PSU + Ethernet Card + IO... Then using network configurator, I make an input output map for the remote rack. To send and receive the data from the remote rack.   I have found this link which I think relates to my question, But I just want to see if any out there has done it and has some more detail, to another doc that they can link. How to Setup your CS/CJ-ETN21 Communication Unit (omron.co.nz)   The final stage would be to set us up to migrate to the NJ platform when the time comes using the existing IO.

I did not know this existed, I will get a quote from Omron.

I am trying to connect a Panel PC (Bartec RS-422) and an Omron PLC (CJ2H RS-232) I am using a Kinematics 2199 RS232 to RS422 converter. Results: Testing software Multiway v9.5 1) Using a usb to rs-232 cable on another PC     - I am able to send and receive a hostlink commands between the panel rs-422 converter and the PC rs-232. commands come through correctly 2) Using the PC to connect to the PLC     - If I connect directly to the PLC using the usb to serial cable and a short adapter I made to map the Omron PLC pin out 2-2,3-3, 5-9, I can send and receive hostlink commands to the PLC. Everything works as expected 3) Using the Panel and the USB Cable    - If I connect the usb converter to the Panel I am also able to communicate with the PLC 4) using the RS-422 port on the Panel     - If I connect the panel RS-422 port and converter and then connect to the PLC. I can only send commands; I cannot get any responses come through from the PLC. My converter box has LEDs on the RX and TX channels and I can see the PLC tries to send something. But something must be corrupted as multiway does not show and response.  I have tried a bunch of things but I am at a loss on how to diagnose this issue. Since I can get the two PCs talking to each other sending and receiving, I can rule out any wiring issue between the converter box and Panel.  Since I can plug the USB into the Panel and get it to work correctly, I can rule out any operating system issues and PLC configuration issues. The only link I cannot verify is that from the converter box to the PLC, I am not sure if the PLC can push hostlink data that has not been requested.  I have no idea why I can write to the PLC but not read. If anyone can provide any insights, I would greatly appreciate it, It has been two days and I am stuck. I am looking at maybe getting a logic analyzer to try and see what the PLC is sending back, but that will be months away.  I am happy to try any suggestions
