EthernetKRL Ping from PC via Switch

Angelos Stathis · June 2, 2021 at 2:45 PM

Greetings Forum,

I'd like your help.

Information:

KRC4 Compact

KSS 8.6.7

KR 6 R900

Additional Software:

EthernetKRL 3.1.2

KUKA.PROFINET MS 5.0.3

DiagnosisSafety 3.1.5

KUKA.DeviceConnector 2.1.4

X11 not yet configured

I am trying to ping the robot controller from my desktop. Desktop & controller are both on a switch, along with a Cognex camera (that I'm going to establish communication with), which connects to a router for internet.

My Ethernet cable is connected to X66.

Inside the manuals I discovered that "PROFINET automatically occupies the virtual interface “virtual5”. This must be adapted to PROFINET"

So as instructed, I created virtual6, with the IP and Subnet mask I want for my LAN (checked as windows interface).

Please see .zip file for included photos.

My problem is that I cannot even ping the controller. Even the led light on the switch for link/act remains dark. Wire-shark doesn't detect any packages. I have 0 response.

I am also not using one of three reserved subnets.

Desktop

192.168.1.81

255.255.255.0

Virtual6

192.168.1.91

255.255.255.0

Virtual5

172.31.1.147

255.255.0.0

I understand that this is an easy task, what am I missing?

you should be able to ping each of the addresses as long as your computer that you are pinging from is configured to be in the same address range and cable is ok. maybe internal cable connecting to KLI to X66 is not ok or plugged in correctly.

could you also send a pcture of the switch?

normally you should the power led on and as soon as a cable is connected and the pc is on you should also have the led for this port on.

here you can see how the leds are on:

This suggests that the port is electrically dead. Try connecting the ethernet cable directly between X66 and your computer.

check tour system schematic. if the switch is internal to KRC, check if it is powered. it may need user to supply power to it or install jumpers to route internal power to the switch.

Turns out the cable inside the controller was faulty. I plugged the Ethernet cable directly to the KLI Ethernet port on the motherboard, bypassing the cable coming from the X66 port. Connection was instant and I was able to ping the IP address as expected.

Can you send me <....> Package

Contact KUKA and get quote. Asking for commercial products is engaging in software piracy. This is against forum rules and will get you banned.
