LabVIEW Connection to Ethernet IP I/O

Does anyone have information on how to connect LabView to an Ethernet IP I/O?

Unfortunately National Instruments does not have any hardware that natively communicates using the EtherNet IP protocol. You can easily implement applications in LabVIEW that use simple TCP/IP or UPD communication, but I do not know enough about the EtherNet IP protocol specification to know if these standard protocols will work. As you mentioned, LabVIEW can interface with an OPC server. If you have any hardware which uses this protocol that can access the OPC server tags, then this would be your best option.
How is this generally done even outside of LabVIEW? Namely, if I have just a PC without a PLC attached, how can I communicate using this protocol from another software interface? If there are PCI or USB devices available that can use this protocol, then you may be able to utilize them from LabVIEW. I hope this information is useful for you. Please post back if we can provide any additional assistance. Thanks,

Labview will not recognize Sony camera connected via ethernet.

I have a Sony camera, model XCG-SX97E, and have been trying to interface it using Labview. I was told that the easiest way to do so is using the NI Vision packadge. However it became quickly appearent that Labview will not recognize the camera at all. It is connected via ethernet directly to my computer. I have tried using NI MAX and Instument I/O assitant, neither of which displayed ethernet or the device as an option. I have never tried to interface a third party device before and am at a loss at how to proceed. If it helps to know, my computer has only one ethernet port, which is taken up by the camera when connected, and it has an Intel 82479LM Gigabit ethernet network connection.

After talking to tech support, I have dont the following:
1) Uninstalled Sony drivers
- This allowed the camera to show up in MAX
2) Created a homemade cross over cable because I do not own one
3) Disabled my firewall
Now, when I try to acquire an image in MAX, I get the error 0xBFF69031: "The system did not recieve test packet from the camera."
I have tried all the suggestions listed on http://digital.ni.com/public.nsf/allkb/4D0ECFAA9AD9FF3E8625792600551A1E and have had no luck.
I am now going to try the solutions found in this thread: http://forums.ni.com/t5/Machine-Vision/0xBFF69001-0xBFFF800B-errors-with-GigE-JAI-CV-A10GE/td-p/1742...

Modbus connection through ethernet using the NI Modbus library

Hi, first of all I want to say that I'm new to Labview, so I'm in the studying phase and I may have very basic questions.
There's a tool that's basically a big screwdriver with a controller that can be programmed to make certain jobs using desired speed and torque, it's called Handy2000. You can save in different channels the configurations for the different jobs. The controller has its own software, and I can already connect to it and read/write with no problem using an ethernet cable.
I was asked to make an interface in labview to select the channels, show in a graphic way (with photos of the electronic components) what screws correspond to that channel, and show when the steps of a job are done. All of this will be in a panel pc connected to the tool's controller.
Since I'm new to labview and to the modbus protocol, I took some time to study the basics. I understand how the protocol works and the very basics of labview programming, so I have an idea of how the front panel will be and what things needs to be modified. But now it's time to start the implementation, and I'm a little lost on how to make the basic configuration to setup the connection and start writing the addresses on labview. By the way I don't have the DSC module, I only have to use the NI Modbus library.
I already checked the example functions to use my pc as master and slave and watched the codes for the different type of data (coil, input, input register, holding register), but I don't know how I should start programming, and the most important thing is how to make some tests in the process to check that I'm having the communication between the pc and the controller. I already read in the forum and learned a lot, but failed to see as a completely newbie how to make and change the basic setups to make the thing work.
So any help is welcome, specific answers about how to make the basic setup and how to test it, vi examples or basic tutorials to read.
Thanks in advance,
Stefan Christiansen
p.s: I attached the manual that specifies the addresses for the modbus communication, so if you could give me an example of where I should change the address in the labview code and what should I put to make a basic read or write it would be very helpful

I can't even know if it's connected right
First I opened the Master Ethernet Example and the Slave Ethernet Example, and everything worked fine.
Now I tried to do it connected with ethernet cable to the controller using the Master Ethernet Example, and set the "Remote IP Address" to the address of the controller (which I already tested with ping and the connection with my PC is fine, and also I have no problem reading and writing with the controller's software). And when I run it, I get the error 56. The error tells me that it happens at TCP Read in MB Ethernet receive.vi:5. I attached the photo of that vi.
I really hope you can help, I need to establish the connection and being able to read/write at least something.

How to detect device connected to Ethernet

Hi,
How do I detect devices connected to Ethernet using LabVIEW.
My requirement is:
I need to detect all devices connected to ethernet in my network.Need to list down all IP of the devices.
Can anyone help me in this...

Found it. However its written a long time ago when I still created spagetti diagrams that give you eye diarrhea, and its bad coding. If someone should use it and cleans it up, please post the cleaned up version
It uses the arp command. prob. other ways to solve this too

Powerbook G4 can't connect via ethernet but connects via airport

We have a small office network connected to an Efficient Networks DSL router that's managed by our isp. The router has 4 ports and a linksys 8 port switch is connected to one of those ports. Another D-Link wireless router/switch is connected to another port.
2 i-macs connect without problem via ethernet cable. They are set to DHCP and get 192.xx private addresses. Both run 10.4.5. Another older imac running 9.2.2. also has no problems.
I recently purchased a powerbook G4 and it will not connect via ethernet to the Efficient networks router. At first it was connected to the linksys, so decided to connect it direct to the Efficient Networks router. With DHCP, it acquires a 169. internet address which is self generated (i.e. no real connection). I tried to give it a static private address (talking to the isp provider). They could see the powerbook but saw all zero's (presumable mac address). By the way the Powerbook works perfectly at home connected via ethernet cable to a D-Link router connected to a cable modem so it's not a physical problem. I even checked the ethernet cable I used in the office with another computer - no problem.
When I switch to airport in the office, the powerbook connects to the network and the internet. I get some strange warning messages showing the server's and the router's private ip addresses. I click ok, and the powerbook finds an unassigned private ip address. It's the only way it will work, but it causes problems, because I can't connect to one of the network printers. Speed also isn't great.
Can anyone give me advise how to proceed. I am no expert on this stuff so keep it as simple as possible.
Tks

Tim,
Thanks for your help. Here's what I've done before reading your e-mail. The D-Link DI-524 wireless router is connected to the Effiicent Neworks DSL router as you mentioned. One ethernet port of the EFF.Net. router is connected to the WAN port of the DI-514.
Because I have a D-Link router at home which works flawlessly with my powerbook, I decided to connect the ethernet cable of the powerbook to the D-Link which has 4 ethernet ports. Lo and behold, the powerbook acquired a private ip address and connected to the LAN and internet!
When I connected the powerbook direct to the Efficient Networks router, it could not communicate. I believe that there must be some software incompatibility between the powerbook and the Efficient Networks router. By connecting to the D-Link, the D-Link assigned an ip address to the powerbook, and it could connect to the server, lan, etc..
Only problem is that I have a Brother network printer that cannot connect to the powerbook. My powerbook cannot find it on the network. Because there is a linksys switch connected to the efficient networks router's third ethernet port, maybe as you said, going through the D-Link via DHCP (when the Linksys is also acting as a DHCP server, might cause this type of problem. What do you think?
As a final note, other imac G5's connected to the linksys switch (which then connects to the Efficient Network's router) have no problem connecting to the lan or internet and have no problem connecting to any of the printers. When I put the powerbook on that switch, I could not connect to the internet - i.e. whether connecting via the lynksys switch or direct with the efficient networks router - same results: no internet connection whether manually or via DHCP.
So the imac G5 has no problem with the efficient networks router but the powerbook G4 hits a brick wall. The G4 likes the D-Link router. I am concerned (and I will have to check this) that if I turn off the dhcp server feature from the D-Link, that whatever software issue crops up between the powerbook and the Efficient Networks router, will rise up again, because the D-Link will act like a simple switch (just like my linksys switch), and we'll be back to square zero. In any case, no harm in trying. This may be the cause of the Powerbook not seeing that Brother printer (even though it sees another printer and other macs).
Having spent hours reading about network problems, I think it's safe to say that macs have problems with certain routers. Why a G5 works and a powerbook G4 doesn't is beyond me, but clearly software must play a role.

How to connect 2 ethernet cables to 1 port? Help me please.

My computer has one ethernet port, but I need to be able to connect two ethernet cables to it.
I am about to get satellite internet which requires an ethernet port and also about to sign up to a VoIP (Voice over IP) service which also requires an ethernet port.
Is there something I can buy or do to overcome this problem?
Sorry if this question seems obvious, but I really don't have a clue and would be very thankful for some good advice.
Cheers,
Crystal Venus.

Crystal,
You need an Ethernet Hub, or Router. This will allow you to "Split" the connection from your satellite internet to the VOIP phone box, and to your computer. These are readily available at any computer store, like Best Buy, CompUSA etc.
Your internet provider might even have some info for you on this front.

I am unable to set up my new Time Capsule with my BT Home Hub - every time i connect the ethernet cable from Wan port to Home Hub, the internet signal drops

Hi there -
I've just purchased a new Time Capsule, and would like to set up a small home network with my Laptop, iMac and wireless printer. I'm following the first steps, but as soon as I connect an ethernet cable between the WAN port of the TC and the ethernet port of the HH, my BT internet connection drops out and I have to restart the HH. Upon which point it drops out again. The airport utility can see my TC, and gets as far as me typing in the new network name and setting up a password, but then it can't quite get through to the next stage. All the time it's just flashing amber.
Please help!

Setup the TC in bridge mode before you cannot it to the HH.
Simply do the setup fully in isolation. And do it by ethernet.
Setup wireless to create a wireless network.
You can use either same SSID =Wireless name as the HH .. same security same password.
Or use a different name and setup.. totally up to you.
Update the TC and then plug it into the HH by ethernet.

How can i airplay from my mac connected through ethernet to an aple tv 2 on wifi

Hi everyone..
im having troubles using Airplay on my mac.. i connect my mac to the internet and home network using an ethernet connection to my router (non apple branded router) .. my apple tv 2 is connected to my home wifi network from the same router.. when i first set up my apple tv.. i was able to see the Airplay icon on itunes and it would let me Airplay media from my mac to my apple tv.. however.. it disconnects after a little while.. same thing with viewing my itunes library from apple tv.. i was able to detect my shared library from the apple tv.. i was able to play some media but then it disconnected after some time.. but now.. the Airplay icon doesnt show up in itunes anymore.. and i cant see my shared library from my apple tv neither.. ive looked around for a solution and followed the tip to turn the ipv6 off.. it worked for some time but now the problem is back..
i know the obvious solution is to connect my mac to the same wireless network as my apple tv.. but i would like to keep it connected through ethernet..
Mac OS X Lion 10.7.4
Apple TV 2 software version 4.4.4
Thanks in advance

I wouldn't say that was the obvious answer at all, my Mac is connected by ethernet and 6 of my 7 Apple TV's are connected by wifi, I haven't had any of your problems. The problem is most likely on your network.
Intermittent problems
Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.
Consistent Problems
A frequent cause of consistent failure to enable AirPlay or HomeSharing at all, is the service being blocked on the network. Make sure your network isn't hidden, has a unique name, that MAC address authentication is disabled, security is set to use WPA 2 Personal and that there is only one router/device acting as a DHCP server and providing NAT services.
Make sure your router/computer allows access over the following ports

Refer to your router manual/manufacturer for any settings that are specific to that model.
Another frequent cause of consistent failure to enable AirPlay or HomeSharing at all, is security software, in many cases configuring it correctly, disabling it or even uninstalling it can help, but in some cases the security software can cause problems that simply reconfiguring, disabling or uninstalling cannot reverse.
If you are consistently unable to activate AirPlay, have tried all the steps in this article and have security software installed on your system, you might benefit from contacting its provider or participating in any online forums they run to discuss the matter with them.

HT1178 Do I want to create a new wireless network or join my current network? I can't connect an ethernet cable to the Mac / printer and to the wireless modem at same time - in two different rooms.

I am trying to set up Time Capsule so that I can do my first backup (after 1 1/2 years!) with Time Machine. I have read other forums, but in each case they instructions eventually do not apply.
I have connected my TC to my existing wireless router. This sits in a bedroom and cannot be moved as a rental home.
I have plugged in the TC and updated the software.
Now - do I want to A Create a New Wireless Network (remember I can't connect the TC to Mac using an Ethernet cable). B Replace an existing base station or wireless router with TC (only intend to use for TM as don't know other benefits as of yet). or C want TC to join current network.
Thinking C. If I choose C, it then asks A TC to wireless join current network (NO as already connected using Ethernet). B want to connect TC to my network using Ethernet to extend my existing wireless network. C want to disable the wireless network on this TC and connect it to my computer or network using Ethernet - CANNOT do this as devices can not be in the same room.
Or do I want to create new wireless network - first set of questions - choice A? What is the benefit to creating a new one when I won't be in this rental house for longer than 18 more months??
Please help and quickly! Thanks!

Let me suggest some things.
But first ask exactly what wireless router you have now and what type of broadband service?
Are you happy with the wireless on the current router? If so, then you can plug the TC straight into whatever computer you have by ethernet, short 1M cord with no connection to the network. And use it without affecting your existing network at all. This is trivial setup.
Although you don't say exactly what Mac and printer you are using, is it a desktop? Laptop it is definitely easier not to plug it in, but a desktop you can plug in the TC and it will all sit happily together.
How is the printer connected and to what?
I am not sure why you need such quick help.. this is all minor setup stuff.. and 18months in todays world is like permanent man.
Your multiple A, B, C are more confusing than helpful.
The best choices without more info.. are to replace the existing wireless router with the TC. ie your option B.. but how to do this depends on the type of connection. Is it cable or adsl? Can you easily bridge the existing modem router.. if that is what it is?
Think carefully in the ideal world what would you like..
and what do you have..
We can probably suggest ways and means to fit what you like to what you have.. without introducing a stack of options that are doing your head in.

I have Fios. I have the TC connected via ethernet to the Fios router. TC WAN port ethernet to Fios Lan port. Then I just have the TC create a wireless network that is different than the Fios wireless network. How do I set up an Airport Extreme to the TC?

The Airport Extreme is a 4th Gen unit. I just want to keep the TC wireless name to go further through my house.

The Ethernet connection will be from one of the LAN <-> ports on the TC to the WAN port (circle of dots icon) on the AirPort Extreme.
Then you can use AirPort Utility - Manual Setup to configure the AirPort Extreme as follows:
Click the Wireless tab located just below the row of icons
Wireless Mode = Create a wireless network (Not "extend a wireless network" as many users incorrectly think)
Wireless Network Name = Same name as your TC network
No check mark needed next to "Allow this network to be extended"
Radio Mode = Automatic
Channel = Automatic
Wireless Security = Same setting as the TC network
Wireless Password = Same setting as the TC network
Confirm Password
Click the Internet icon
Click the Internet Connection tab
Connect Using = Ethernet
Connection Sharing = Off (Bridge Mode)
Update to save settings and restart the entire network
Computers on the TC network will now be able to move to the area where the AirPort Extreme is located and not have to "switch" networks. This is known as a "roaming" network.

I now wish to add a second Airport extreme but am considering a hard wire connection with 100 ft of cat 6 cable from the Time capsule to the second Airport extreme. Can my network operate properly to extend the network with both a wireless and wired extend functionallity?

I now wish to add a second Airport extreme but am considering a hard wire connection with 100 ft of cat 6 cable from the Time capsule to the second Airport extreme.
Excellent plan.
Can my network operate properly to extend the network with both a wireless and wired extend functionallity?
Yes, but don't get confused about the second AirPort Extreme, as it would not be configured to "extend" a wireless network.....it would be configured to "create a wireless network" using the same wireless network name, security settings and password as the Time Capsule network. Configure the second Extreme in Bridge Mode.
This Apple support document will show you how to hookup and configure the second AirPort Extreme:

Thanks.

Download and install AirPort Utility 5.4.2 for Mac OS X 10.4.11 "Tiger" here:
AirPort Utility 5.4.2
Once installed, launch AirPort Utility. It will tell you if a firmware upgrade is available for your Express.

Can you connect an ethernet cable to an Airport Express Extension?

I have an Airport Express that I am using as an extension to my current home wireless network.
That is successful and I have a green light. I am trying to plug in an ethernet cable to allow an older mac without an airport card to connect to that Airport Express Extension. When I turn off the airport and select Ethernet Cable, I am told that the cable is not connected to the internet. The wireless works fine and I can get full bars in the far part of my house - but I do not get internet when connecting an Ethernet cable.
Help!
Thanks in advance
