How can I resolve 'Incompatible IP Settings' NI Max?

Hi all, I'm using LabVIEW 2012 SP1, my hardware is a NI 3110 industrial controller, which connects to various Beckhoff EtherCAT Terminals.

I'm having a problem with 'Incompatible IP Settings' NI Max when I try to connect to my goal of RT (NOR-3110 industrial controller). I am able to connect to the target without problem, but be it via DHCP or static IP address, I keep getting 'Inconsistent IP Settings'. I downloaded a few screenshots to imgur album, you can see here. Here is a list of things I've tried (and various combinations):

1 / flipped "IP Reset" switch on the controller, reset it and put the ip of the PC to a static IP address on the same subnet.

2 / hit the 'Safe Mode' switch the Safe Mode boot target and connect.

3 / formatting of the target and reset network through MAX cards.

4 / DHCP configuration where the target has it of own IP assigned automatically and is visible on my network of the University.

To be clear, I am * not * having a problem connecting to my target, it is very easy to connect via DHCP and static IP, but I can't seem to get rid of incompatible IP settings.

I have read many topics Forum and knowledge base articles that suggest that this is usually the result of the IP address of the target and the PC is on a different subnet. However, as far as I can tell this is absolutely * not * the case. The IP address of the target is 10.158.20.8, and the host PC is 10.158.20.x (this varies) and the subnet mask is 255.255.255.0 for IP addresses * are * on the same subnet. I even put it in one of these subnet calculators just to be absolutely sure.

One thing that stood out to me, is when I have the controller connected to the network with DHCP on and it automatically 10.158.20.8, he has a strange subnet mask (see image 4 here), I assumed it would be 255.255.255.0 as when I do ipconfig at the command prompt. Could it be the cause of the inconsistency? If so, can I change?

Also, every time I reset the target thanks to MAX (after the change of the DHCP server to the static IP, or vice versa) MAX does not connect to it again automatically, I have to delete the target and MAX of refreshment and it records again.

The finals 2 screenshots in the imgur album (found here) are the video output of the controller (just connect a monitor with a VGA cable with an adapter). Picture 5 is what I * currently * see and the last image is a screenshot of old, what it * should * look like. In the first splash screen image, the message "error boot disk program initialization" sticks out, which indicates some kind of hardware malfunction? I don't remember when I see a message like this when I originally set up this system.

So in summary, I get 'Incompatible IP Settings' - I tried all the usual suspects, all IP addresses are on the same subnet, etc., it seems that there is some * other * problem which is at the origin of the incompatible IP settings that I can not detect. Any help is greatly appreciated, since I have this error I can't install software to the target, which means that I can not install NI-industrial Communications for EtherCAT, aka I can't do anything until I have fix this. Please let me know if there is additional information, that I can provide as well.

All the best,

PS, I've created a report to technical support at MAX and it attached in case it is useful for your comments!

Hey thanks for your reply. The images were in an album of imgur related to the position. I tried actually all to connect to the controller, I made sure that my network card has had to function to automatically detect the crossover (apparently it is the industry standard for Gigabit Ethernet cards). I even managed to try two controllers, a colleague had a spare, and finally the problem turns out to be an incompatibility of the software. I borrowed a laptop of University Department and installed the same software I have on my original laptop and tried to connect to the controller and it worked fine, no incompatible IP settings.

From there I could say that the problem was related to the original laptop, since settings incompatible IP was not on the borrowed laptop. I actually ended up completely reinstall LabVIEW on the laptop original just in case it was somehow a facility damaged from somewhere. However, I noticed that a colleague had updated the Configuration of the system NOR to 15.0. If I remember, it is usually backward compatibility to the previous 3 versions of LabVIEW, sort of version 15 with a LabVIEW 2012 SP1 works very well. However, during this new LabVIEW installation (before I updated day NOR Sys Config 15) I checked the controller, and I connected to it fine, no errors. Then I installed the version 15 of the Sys Config and * then * got parameters incompatible IP. The better I can understand, is that it is some sort of bug in verses backward compatibility between OR System Configuration 15 on a LabVIEW 2012 SP1 install. That, or it is related to the fact that the controller I use is waaaay out of fashion and unsupported by certain aspects of our days.

Thanks for your reply anyway, I forgot to post the solution I found here, so I hope that if anyone has this problem, they can check their compatibility of versions and things like that!
