Boot application

Jetman

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

Hmm, seems like a bug processing the the subnet mask...

A quick solution is to have your IT dep. to configure the dhcp server to return the fixed ip number for the specific mac addr of the IRC5 controller.

If the above is tried out, do you then still get the "wrong" address?

Hi Laro88,

 

Thanks for your help.

 

I checked in the Info section of ABB and I didn't find the Mac address of the controller.

 

Where is this information located? Is it in the boot application section? I will have a look there just in case.

 

I cannot ask the school to change their address but when I use regular address like 192.168.x.x it always work. But since school use weird addresses starting with 10 and 8, I often get that error. I also have other errors with those addresses, for exemple, in RS you can see the robot but the Connect button is not avalaible.

 

I have the feeling that it is a problem with the robot and that no one knows about it since they always use "standard" IP addresses. Nothing sure though.

 

I reinstalled the system and upraged the boot application many times but no luck. I am running 5.12.01_SE

Hello,

It does seem strange...

 

We will have a look at it and write back when we have a result.

I just looked for the MAC address on my two IRC5s, it does not seem to be printed anywhere.

Open the Flex pendant, and do a SystemDiagnostics.

Open the generated file, and search for "MAC-address" - without "'s. :-)

You will find something like this:
__________________________________________________________________
LAN port configuration
Type    Ip-address    Netmask        Gateway        MAC-address
----    ----------    -------        ---------    -----------
FIXIP    192.168.100.202    255.255.255.0    192.168.100.1    00:00:23:0e:09:62


Port    Ip-address    Netmask        Broadcast    MAC-address
----    ----------    -------        ---------    -----------
LAN    192.168.100.202    255.255.255.0    192.168.100.255    00:00:23:0e:09:62
GTPU    192.168.126.1    255.255.255.0    192.168.125.255    00:00:23:0e:5e:b0
SERVICE    192.168.125.1    255.255.255.0    192.168.125.255    00:00:23:0e:5e:b0
AXC1    192.168.127.1    255.255.255.0    192.168.127.255    00:00:23:0e:33:ab
__________________________________________________________________

The appropriate mac number ( that your it dep should assign the ip info to) would be the one ending on 62 on my system.  (LAN)  Your MACID would be something else as they are supposed to be globally unique, however it is NOT always the case.

Thank you both,

 

While using DHCP on the robot the IT guys were able to retrieve the MAC address. Next step is to have the DHCP server force the address we want to that MAC for our robot.

 

It's a patch but I'm pretty sure it will works. Will be waiting for ABB results.

 

I will do as you said to get the MAC addresses Laro88, thanks for the tip.
