How to find IP of CMM Controller?


---
 Share

Recommended Posts

Recently, our IT department worked on our CMM computer because of network problems we were having. They fixed the network problems, but now our CMM doesn't connect to the computer at all. I get this error message: InterfaceOpen:Connect error:(WSAGetLastError:10051. From what I've read, I think all I have to do is set the static IP address for that ethernet port to the CMM controller. However, I don't know how to find what that is. Any ideas?

Jacob, ipconfig only tells me that "media is disconnected". Computer literally thinks nothing is connected, even though the lights in both ports are lit up.

Clark, that's actually the one thread that I've been referencing. No one mentions how to obtain the IP address.

Maybe not the way to find it 'if' it's not there but, on the windows 7 system I'm on now,
open up windows explorer, go to windows\ System32\drivers\etc, right click on the host file and use Notepad to open up the file and it shows the CMM IP address.
Should be something like 192.4.1.200 cmm_1 cmm_1 #controler1.

No worries. Apparently the issue is a little bigger than just plugging in the ip address. Zeiss wants us to have the "obtain dns server automatically" ticked on, but when we enter in a static ip, that option is grayed out. Everyone is confused 🧑‍💻

There are two network cards in a computer connecting to the CMM, one goes to your network (that one is up to your IT person to setup correctly based on your needs) and one goes to the control.

The one that goes to your control needs Internet Protocol Version 4 (TCP/IPv4) installed, then the settings should be setup so that it is setup to have "Use the following IP address" checked.

The IP should be set to 192.4.1.199 and the subnet mask should be set to 255.255.255.0

I am not sure who told you that from Zeiss but the next setting should not be "Obtain DNS server address automatically"

"Use the following DNS server addresses" is the one that should be checked.

The DNS server addresses should be left blank.

There is no reason for that network card to ever perform a DNS lookup since the only thing it will ever contact is the controller and that is at a specific address.

A DNS lookup is when the machine connects the Domain Name Servers that run the internet and allow for translation of domain names into IP addresses and is entirely unnecessary in this situation.

I think IT restored the ethernet ports to default. Our working CMM has the cmm port "Zeiss-CMM", while the computer we're having problems with just says "Local Area Network 2". Even when plugged in, with lights blinking, the computer doesn't recognize any connection. The controller doesn't respond to any pings.

Unfortunately, the facility that I work in doesn't allow outside companies to "remote in" either. So this has just been a fun experience.

Hum, there are some generalizing statements here thats not necessarily true.

Since the connection to the cmm usually is a LAN, the fourth digit can be anything between 1-254, it just doesnt matter, regardless of what anyone at Zeiss says. But it doesnt have to be a class c network either. (More on that further down)

And not all "online" computers have two network cards. Due to "security" issues that I wont go in to here, both the CMM and the computer could be connected together over the "regular" company LAN or a special LAN for CNC/CMM's. In that case the computer would only require one network card. Here where I work is one example of a company that takes the word it-security to an whole other dimension.

And to make it even more confusing, the Ip-adress of the controller can be changed, so it can practically be anything between 0.0.0.0 to 255.255.255.254. All depending on the customers reqirements.

But the most usual setups do use an ip-adress 192.4.1.1-254, but there is no the "adress shall be".

Yes - you are correct - it IS definitely possible to make up pretty much any weird configuration you wan't on a network. I think the cases of this happening are pretty rare though (I am happy to admit that its possible I could be wrong about this).

In general I would expect that if you have a weird network setup, you probably should already know about it because there must have been some actual reason for you to have set it up to non standard to begin with.

In order to have been 100% clear I should have specified that my comments reflect the default settings that a 'standard' Zeiss installation uses if you buy the PC/CMM from Zeiss and have them install it.

A PC purchased from Zeiss comes configured with two network cards by default.

One is configured to use the settings I listed above and the second card is included with the intent that it can be used on a local area network.

Figured out what was wrong (I think). In the network adapter settings, you select the properties of the port the CMM is using. For us, there was a "Cisco Anyconnect" check marked. I figured it didn't need it so I unchecked it, and amazingly it started working within seconds. Thanks for all the help guys, learned a lot in this one.

What would the network settings look like in this situation? I'm in the process of upgrading our PC that has only one Ethernet port, and I'm assuming the CMM, PC and LAN connections would all be plugged into a switch.

They (IT) use network routing, with a static ip adress assined to every unit connected.

But the exact details I dont have. My old pal at the IT departement is retired. And the young guns dont "trust" me... Yet 🙂
