Hi

I can't find IP of PLC. I tried to use below procedure

https://www.myomron.com/index.php?action=kb&article=1487

but still no success. I attached printscreens and I don't know how I can get mentioned IP 169.254.XXX.XXX . I did as Myomron suggested - tick OFF and ON "Disable The direct Ethernet"

 

Any clue?

Turn off that bottom check box.

As I wrote i did tick OFF and ON and nothing changed

Is there an Ethernet switch in between your PC and PLC?

This is what the Direct Ethernet Utility creates when it is active. If you enable it and enter ipconfig /all in the command prompt you should see the 169 address. You'll have 2 IPV4 addresses:

that is exactly opposite of what is in linked instructions and suggestions.

when checkmark is set, function is disabled.

I believe that he is saying that he did both (on and off) and it did not work either way. 

I would suggest unchecking the box and connecting directly to the PLC with a cable (no switch) as photovoltaic was suggesting.

I decided to check it on other PC, and it is working as it should. The same system win7 64bit, the same software

Problematic PC has a problem to get second IP IP 169.254.XXX.XXX.  No switch, direct connection.

Do you have any idea what global network/windows settings can block it?

I have seen windows block this a few times. It generally happens on computers that have either strict and locked down networking rules or a lot of networking type software (VPNs, IIS  utilizing programs). On every occasion I have seen it I have been able to make a connection by IP address,

If I know IP address I can connect without any problem, but sometimes IP is unknown for me and Middleware solution would be useful for me.

Did you investigate how to switching off such a blocking?
