Hi guys,
I know a little about networking but not enough in this case I guess.
So I have a network question for the networking gurus out there ![]()
We installed an IRC5 system in a school. The IT guys there told us to use these fixed addresses:
IP 10.38.5.1 trough 10.38.5.20
Mask 255.255.0.0
Gateway 10.38.0.1
*note that the mask is NOT 255.255.255.0
When we boot the system, address 8.32.5.9 is shown beside the system’s name in the main ABB screen.
I was expcting to have address 10.38.5.11 there because it’s the one I chose in the boot application but no such luck.
Now we could think that there is a problem with the DHCP of the server but even if I completly unplug the network cable from the controller, this same strange address stays there (8.32.5.9).
I tried many other addresses. Here are the results:
10.38.5.15
Mask 255.255.0.0
Gate 10.38.0.1
and it gives (8.32.5.13)
Then I changed the Mask to a more “normal mask”
10.38.5.11
Mask 255.255.255.0
Gate 10.38.5.1
Hurray! It finaly gave (10.38.5.11) which is what I asked for. The problem though, is that the gateway that was entered there is not really a gateway at this school, it’s just a regular ip address. And even though the robot seems to be ok because the right IP address is shown in the main ABB screen, I cannot see it with a PC (RobotStudio) on the same network. I assume it’s because of the mask. I choose a 255.255.255.0 and the school uses 255.255.0.0.
Also, If I use the DHCP option in the boot application then it works fine, i get a random IP from the DHCP and I can connect with RobotStudio.
Problem is, we love fix IPs.![]()
What is the problem? What are those not-so-funny 8.32.5.x ip addresses comming from? Again, these addresses are there even when the controller is not connected to the network.
Thanks,
Jet
