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.

Thanks for the links.    These examples are interesting, but if I were to use the IEC style function blocks I am afraid my MAINT. team would revolt against me.  We don't use that style of code here at all and I try to keep things simple.    Does anyone have any ideas/examples using the simple ladder? 

That does look helpful..  but how do i find that?  ( I hate MITS website, can never find anything I want/need )

Like Luke said above, you can assign multiple functions to a single button. See attached. But this dialog box only comes up if you select Object>Switch>Switch.  Selecting Bit switch or the other options will bring up a more limited dialog box.     If the alarm screen is a popup, you can set the window register to 0

Specific Output/Input External Out/In General Out/In Can someone give me a quick difference between these I/O types? I am trying to correct our interference cube setup and I thought there was a hard wired IN-Cube signal and Prohibit signal, but it seems our system is using PLC I/O between the robots. 

BOOM! That chart is killer! Thank you so much. The card is set up as station 25, that must have been what was wrong with my network settings before.   

I have never set up a CCLink network before, but seemed pretty easy using the Network Parameters.  However once connected, we were not able to read/write the bits as expected.  The Japanese associate from the machine builder wrote the following 3 lines of code and cleared out the settings from Network Parameters.   Three quesitons about this: Could someone explain why my settings were wrong?  How did he know the H110 | H190 | H240 addresses? and what does K4X1000 Mean?    --- [FROM H0B H110 K4X1000 K16] ---[TO H0B H190 K4Y1000 K16] ---[TO H0B H240 D2000 K16]

Do you see anything wrong with my setup that would explain it not working the same? 

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? 

Yes this is a Q series plc, using GXDeveloper.   Do the remote modules have rotary switches for address numbers? I have never touched the remote I/O on this cell, or any Mits system, I am more familiar with Omron and Yaskawa hardware. 

I was able to clear the message by killing power to the entire cell, but still have no idea what device had an error.
