OK... so solution was... wait for it... wrong EDS provided by KUKA. With correct EDS everything works. They assured its correct.
The thing is that all points that were listed by You was triple checked by me. Minor major versions which were messed up in EDS file and some other things but not so revelant.
Conclusion: Make sure you have vendor, minor and major versions correct!!!! Even if producer gives you EDS saying that it is 100% correct one.
BIG THANKS for help.
Sorry. I hope You have not been offended with my proposition. Currently I will connect KRC4 (master) with Schneider (slave) and Schneider with Omron using other protocol. Anything else communicates with Omron using EtherCAT which is unavailable in Schneider. Expensive solution, but it HAVE to be done.
Unfortunately we failed to communicate omron as master when KUKA is slave. I don't have communication with omron at all 
Are you willing to help? Not for free of course. I can open VPN tunnel or any other connection accepted by you? We can share solution here after problem is resolved. Please send me private message for access information if you are interested/can help.

OMG, yes that's true 
Thanks for advices. I will check and let you know how it is working (or not :))
Panic mode,
1. Yes
2. Yes
3. No.
I was able to communicate KRC4 as master and schneider as slave. Solution was to import eds file that was generated from SoMachine solution. Before I was using configuration downloaded from schneider website and it wasn't working. Main difference was Minor and Major versions of driver/software. But still I'm not able to communicate omron with KRC4 where KRC4 acts as slave. I can't find option in Visual Workspace to generate eds for current configuration of KRC4. I think this is the main problem. Configuration (eds) is wrong.
4. Yes.
They are mapped. Only after mapping i see this error EIP-SCANNER read/write error.
5. I don't know? haven't found such configuration. I will check/look for those options. Maybe I should set in KRC4 some kind of "less restrictions" mode (only for tests, of course)
For me it's a hudge step that I have any communication (able to toogle gpio).
Thanks for your advices!
Hello!!!
Thanks for your attention.
Yes KRC4 is set up as slave device. We have two different PLC to test:
- OMRON LX1P2
- SCHNEIDER M241
Both are able to communicate with eachother without problems, but no success with KRC4.
After mapping IN's and OUT's KRC4 shows EIP scanner connection timeout. For me it looks like comething "low level" like bad version of EIP driver or misconfigured driver?
We even have KUKA technician on the phone and he is not able to give us step by step guide
IP address is configured correctly, and all devices are able to communicate threw local switch (ping tests)
What is weird, EthernetIP scanner on PC is able to find all EthernetIP devices and even perform write operation to them, but KUKA still shows this EIP-scanner read/write error and timeout?
Where should I go from here?
Hello,
I have same problem but cannot find working solution. I think my configuration is correct see attachments. I can't find anything about virtual5 in EIP? whats that?
After reboot I've got errors:
KSS00099 "Read/Write Error: EIP-ADAPTER"
"timeout during connection between PLC and PLC1"
Any advices?
