Connect Kuka KRC4-Controller to Windows-PC

    Hello,

    i use the kuka ready2_educate cell (KR4 Agilus). i want to connect the kuka-controller to a windows-pc via ethernet-lan, in order to mirror the screen of the controller-pad onto the windows-pc screen for presentation purposes. i can connect the contoller directly to a screen and then control it via mouse and keyboard, but then i can't use the controller anymore and for the presentation it would be much easier if i could use the controller and just mirror the image.

    I wanted to use ultraVCN for that purpose, but i am not getting any connection between the controller and my pc.

    I tried to ping the controller from the pc and the other way around without success. Then i tried changing the ip-adresses, the standard-gateway and the dhcp-server which didnt work either. I've read somewhere that i should use the X66-Port, which is already taken on the robot. I've tried it anyway, which did not work.

    Has anyone an idea how i could get a connection ? thanks in advance

    Approved the thread.

    X66 is a correct port. it is just one port but it can run different services and connect to many nodes - you just need to add Ethernet switch.

    to connect to an Ethernet node, you need to know the network settings of that node. and the machine you are connecting to it will need to have compatible network settings. so far you did not prove that they are compatible.

    Woah... careful there. did you read documentation and pitfalls mentioned in READ FIRST?

    i hope you have created backup image of the robot HDD before touching this, because if anything goes wrong, that will be your way out of trouble.

    post your KLIconfig and state KSS version. if this is at least KSS8.3, you can also use KSI port to connect to robot. KSI port works as DHCP server so your computer would get IP address from the robot and you do NOT want to connect this to your network.

    i changed the ip-adress on the pc, i've read that it should match the ip-adress from the robot (except from the last part), as well as the subnet-mask and standard-gateway. yes i have made a backup.

    ok. If it helps, via WorkVisual i am able to connect with the ksi-port.

    I think the state kss-version ist 8.5.8

    KLIConfig:

    Code

    Edited once, last by k0ndorr_ (May 3, 2024 at 1:39 PM).

    line 10 shows that you did not change IP address. it is still at default 172.31.1.147, subnet mask 255.255.0.0

    line 47 shows that you changed Gateway from 0.0.0.0 to 172.31.1.147 which is a useless setting.

    gateway is used when connecting to a different network and you want to specify address of a gateway to that foreign network. but you are directing any traffic back to itself (KLI interface).

    in addition you did not state network settings of your computer that is supposed to connect to KRC.

    finally i do not see VNC ports enabled. without this you can forget about VNC connection.

    it is clear that you are poking with thing you do not understand so you need to be really careful.

    i would strongly suggest to make full image of the robot HDD before making ANY changes.

    then you can try adapting network configuration. on the robot side you would need a VNC server and to access that server externally, you would need to open VNC port. normally this would be port 5600+N where N is display number.

    then if you have more than one device connecting to X66, you need to add Ethernet switch.

    then you can try running VNC client (viewer) on your machine and try connecting to VNC server
