Networked VI
The following VI runs on a local PC connected to our company network and to an Omron PLC through an additional Ethernet card.
We use OPC server to allow the transfer of data from the PLC to the labview.VI.
We try to make the VI visible on the network. We use therefore Application Builder to make an executable file loaded then on another PC on the network.
This remote PC could never find the data. As we were being told, we changed the addresses of the data from "opc://localhost/..." to opc://IP address (on the PC running the VI and connected to the PC)/..." without any better success (see the attached VI, the last variable at the bottom of the block diagram)
What are we doing wrong? Thanks for your help

Hi,
There are in LabVIEW DSC a tool called OPC Quick Client. Have you tried connect to OPC server from the remote machine with OPC Quick Client?
I think you problem is DCOM security settings and there are some things that you can do. I recommend you visit the site www.opcti.com to get
articles that help you to configure DCOM.

Hi there,
I want to install/move our office over the weekend and have some lose ends, which i hope can be answered in this forum.
First, let me start off mentioning what i intend to do:
we have three (airport enabled) iMacs sitting in the middle of our office.
At the far end of the office we have the DSL modem, a Gigabit Ethernet Switch, the airport extreme station.
At the other end of the office, I have a HP Color LaserJet (networkable) and a PowerMac G5 1.8GhZ DP (has an airport card installed).
I would like to have the three iMacs connected to the Internet, the Printer and the G5 PowerMac (which will serve as a server). I go about that by connecting the Modem with a jumper cable to the Gigabit switch, as well as the Ethernet cable (regular ONE-WAY) from the printer and the G5 into the Gigabit Switch, I assume. Then I lead one Ethernet Cable from the Gigabit Switch into the airport station, so that an (optional) laptop could access all of teh attached goodies.
Eeventhough the iMacs are airport enabled, I would rather have the option of having them hardwired as well (for speed reasons). I just plug those ethernet cables inside the Gigabit Switch as well?
Thats the technical part.
Now a question about the PowerMac G5. Everyone on the network needs to access files which I will store on the G5, such as photo library and some word and xls documents. Can i just make everything shareable?
Thank you in advance for any suggestions/input you might have.
G5 imac, powermac, etc Mac OS X (10.4.6)It sounds like you have it right - if you're using wired ethernet connections just connect everything back to the switch.
For the base station, make sure it's running in bridge rather than route mode - using AirPort Admin Utility, turn off the 'distribute IP addresses' option.
As for the file sharing, I wouldn't share the entire drive, but designate one folder (or folders) as being shared. If this is running Mac OS X client (vs. Server) get a copy of SharePoints which will make it easy to select which folders are available for sharing.
Unless you're also running as a directory server you'll also need to make sure that the G5 has an account for everyone that is going to log onto it to access the shared folders. You could use one common account, but that's not recommended. -
Cannot send email from outlook 2011 (Mac) on public networks but can send via Mac Mail
I cannot send mail with Outlook from anywhere other than my work or home network, will not work even when accessing 4g with my phone hotspot; very frustrating. I am using Yosemite & Macbook Pro (2012). if i use the Apple Mail everything works fine so I can only assume it is a setting on Outlook?
Update - I now have it working.
am not really sure what exactly fixed it.
I changed a lot of things but my setup now has the following which I think fixed.
outgoing server - p06-smtp.mail.me.com
override default port checked - port now 587
on more options button changed it to "use incoming server info". -
I have BT Total Broadband Anywhere Home Hub 2. I have used it successfully on my desktop pc and wirelessly with my laptop. However I went away for 2 months and was unable to use either (everything was switched off whilst away). On my return the laptop can't connect at all, I just get two grey monitors with a red X and the information 'A Network Cable is unplugged'. I bought a netbook when away and am having the same problem with that now.
On the laptop that worked before, on my Network Connections it is showing as follows:
Local Area Connection 2
Network cable unplugged
Broadcom 440 x 10/100 Integrated Controller
1394 Connection 2
Connected
1394 Net Adapter #2
I have tried connecting to the Hub with an ethernet cable without success and when I run the Hub Manager on the laptop it just says it can't connect with the hub. When I run the Hub Manager on my desktop it says there is no wireless device detected.
A check on the laptops device manager hardware shows everything as working properly, but when I try the Wireless WLAN configuration utility in Control Panel it tells me there are currently no wireless adapters available and enabled.
I am getting desperate as I cannot sit at the desktop for any length of time and need the laptop, please can anyone help?chunkleberry wrote:

Hi, the devices you have mentioned are the 'wired' connections. On most laptops, there are switched you can press to turn on and off wireless, is it posisble this has been done?
You can check to see if 'wireless network' appears by selecting the Start Button, then click on Control Panel and open, you should see 'Network' (doing this by memory) and open that up, you will see Wired Lan and Wireless Lan.
If Wireless Lan is disabled, you can right click on wireless lan and enable it, that should work.

AIO Remote wont recognize my network printer deskjet 3050
AIO remote app (IOS) did not recognize my network printer (Deskjet 3050), other apps (printer pro lite) did recognize the printer flawlessly, both the printer and the iphone are in the same network, I can print from my PC and my mac but not from AIO remote app (not even recognize the printer).
Can you help me?Hello MrCrysis,
With the Printer Pro Lite app working to printer, this is excellent to hear. Although this is not an HP app. So to explain as to why the AiO Remote app is not recognizing your printer, and not being able to scan. Your printer does not have AirPrint capabilities according to the 'HP Deskjet 3050 (J610) and 3050A (J611) All-in-One Printer Series Product Specifications'. AirPrint is a requirement for the HP AiO Remote app to work, and because the printer does not have AirPrint the app can not see the printer.

PeterHi Peter,
Welcome to the HP Support Forums. I understand that you are trying to use the new HP AiO Remote app for Windows phones to print to your Photosmart 7150 printer.
The Photosmart 7150 printer only supports USB connectivity, I have include the Photosmart 7150 Printer Specifications for reference. To be able to use the HP AiO Remote app the printer needs to be connected to a wireless network.
If you accidentally typed the incorrect printer model, please let me know which make/model/product number of HP printer that you have. How Do I Find My Model Number or Product Number?

Google Play on Tablet works on WIFI not Verizon network.
I have an Motorola Ellipsis Tablet. I am unable to use Google Player. When I open the app, I get "Background data disable. Google play store needs background data to be enabled." I hit enable and It asks me to choose either Facebook or Gmail. I choose my email account and it tries to sync and I get the message "Sync is currently experiencing problems. It will be back shortly." Everything works fine when I am on WIFI at home but when I get to work and I'm on the Verizon network it won't work. I can't use Pandora or look at video. Can someone help me figure out why it is not working on the Verizon network? Thanks.
Hi Mollie88,
Oh my! Let's get you back to enjoying your device. Some applications depend upon background data (transferring data when not directly in use). Restricting background data may cause those apps to stop functioning unless a Wi-Fi connection is available. To uncheck Restrict background data in the Google Play application, follow the directions in the link http://vz.to/1f5KM7b .

IPad iOS 8.1 Mail constant network use draining battery
Since updating to iOS 8.1, iPad Mail is rapidly draining my battery. When I go into Mail the network usage indicator (spinning wheel) runs constantly. I left it this way by mistake while traveling and it drained the whole battery with minimal actual usage in one day -- I usually only have to recharge every 2-3 days.
I have checked the battery usage indicator in Settings and it shows that in the last 24 hours Mail used 54% of the battery. I had changed no settings, but went into Mail & Calendar settings and double-checked them, and they were as they had always been. I have three email accounts: Gmail, Verizon, and a company account on an Exchange server. It's the only one that was set to Push, but now I've set it to Fetch like the others and it still continuously accesses the network when I'm in Mail.
This must be a bug of some kind introduced by a recent OS or app update, right? This never happened before, and nothing else has changed in my usage of the iPad or Mail.
One other issue: Mail is not actually fetching new mail when it should. I see new mail show up on Mac Mail hours before it appears on the iPad. Normally email would arrive almost simultaneously on my iPhone and iPad, then a moment later on the Mac. Now the phone is still first, but the iPad lags. The only way I can get the iPad to refresh in real time is to close the app and restart it.
Is anyone else seeing this behavior with the recent update? Any idea how to fix it?Found a solution at: http://webcamsocialshopper.com/iphone-battery-suddenly-draining-try-this-non-res tore-method
Short version, remove your Exchange account, shut down phone, restart, add the Exchange account back. Problem solved. -

Thanks.I tried that and it didn't work. As for upgrading the ASA version, I'd like to but this is an old router and I don't have a support contract with Cisco anymore, so I can't access the latest firmware.

Manage-bde command is not generating recovery key on network location
Hi,
I am trying to save the recovery key to the network share location and start up key in the USB drive while enabling bit locker.When the OS drive gets encrypted, the default folder for recovery password shows that it contains 1 file but not getting anything
inside it when i checked the properties of the folder.
i have already changed the group policy as "choose default folder for recovery password".
I am using the command to enable the bit-locker as "manage-bde.exe -on C: -rk
<network location to save recovery key> -sk <location of the USB drive>
-rp to enable the bit-locker. It is generating the start up key in the USB but not the recovery key on network share.
Can anyone suggest what i am missing or what else i should do to generate the recovery key on network share.
Does manage-bde process be able to save the recovery key on network share or it hand over to some other process to perform this task.
Thanks
Gaurav RanjanI got you Manoj, but I want to ask you one think that what if i lost the startup key or my USB stick. I have my recovery key on the network share. In order to log-in my machine I need the recovery password. From where i will get the recovery
password(48 digit). Surely from the recovery key on the network share. So how can i get the recovery password if only we have the recovery key.
I know both are different in context. Both are two different thing. I have lost my USB stick along with the recovery password and I have to log-in my machine. How can i do that i want to know that. Do there is any method to get recovery password from the
recovery key on network share. I have retrieved the recovery password when the recovery key in AD. But this time it is on network share.
Also one think which I need to solve is that the manage-bde -protectors -add command creates a new .bek file along with the older one. So the .bek file which get shown at the time of the start up of the machine is different from that stored in the network.
So i am getting confused as which .bek file is for which machine and hard to retrieve the password.
Is there any method to store recovery key on network without the -protectors -add command line so that both the .bek file should be matched and can easily be known for indiviual machine in an OU. As if both the .bek files will be different it would be difficult
to to retrieve the recovery password for the machines.
Please do inform if you need some more information about the scenario if i missed something.
Thanks

New C310 - Wireless working FAIL - Printer's wireless network seems to be dead
Product: HP Photosmart Premium C310
OS: Windows Vista 64 bit and Windows 7 64 Bit
Error: Wireless working: FAIL
Changes: No changes since this is the first install of this printer ever
Description:
I've just unpacked my new C310 as a replacement for my older HP Inktjet 3845.
But when trying to install the wireless network everything I try seems to fail.
Printer doesn't detect my wireless network (blue wireless led is blinking 1sec on - 1sec off )
HP Network test tool on my laptop (standing next to the printer to test it's location ) gives no issues whatsoever, wireless network is strong and working very well.
Settings of the wifi connection are WPA security, no WPS, Channel 11, ... .
When I run a Wireless Network Test report from the printer menu, the result is (= printout)
* Wireless On => PASS
* Wireless Working => FAIL
* All the other points below are on status NOT RUN so no connection at all ...
Solutions tested:
Tried to reboot printer while waiting 1 minute in between => No result
Reset to factory settings straight on the printer => No result
Tried to run the Wireless network Setup Wizzard several times without merit.
Explanations on the forums seemed to be that this might be a faulty wireless network card in the printer?
Since this is one of the reasons of buying this item, I do need it to work.
Can anyone provide me advice/next steps?
Kind regards,
RafGreat info and troubleshooting, thanks!

New MBP - wireless/internet access networking problem - a summary!
Greetings!
New MBP here, with all the trimmings (MacOS X 10.4.10 - Safari 3 Beta). New also to the Apple/MAC world
MBP >> wireless networking into a Linksys WRT54G router and >> thru HughesNet DW7000 Satellite Internet connection (not the fastest, but hey, the US and especially rural areas are NOT S. Korea when it comes to speedy internet connections!
Frankly, I bought into it for two reasons: First, hearing about the vaunted Mac a/v/ and doc/photo editing capabilities,... and about MacOS stability, etc... Well, it all needs a little work still: on the part of new users like me, but also probably on the part of the Apple/Mac people as well. 2nd reason I decided to purchase the MBP - i.e. ability to run Windows (I have not yet tried BootCanp, etc...: still resolving preliminary issues!). I still live in a heavy Win environment at my business - no other way of course!
Communications issues seem to still prevail: I am hanging out at several VERY HELPFUL forums (AppleDiscussionForum, MacRumorsForums, etc...) and the same issues keep popping up. Im my case, same as all above reported, with a few additional points, as follows:
1. Xmission errors: seem to be - at least in my case - a constant factor, regardless on how close/far i am from my wireless router. For example, I would be attempting to dwnload an upgrade (large)QT or MacOS file. i am barely into the dowmoad, and I already have several Read/Send errors. By the end of the download, I will have probably about 15 Rcv and 5 Send errors. Never gets quite that bad in my Win machines, I must mention. Anything to do here (I know, there are such things always affecting wireless com). AND, MOST importantly, how that this affect the effectiveness of the upgrade (I spotted same thing with MacOS 10.4.10 and Safari Beta 3 upgrade downloads!). Would it be likely that applying upgrades in such circumstances would screw up the OS??? Could OTOH such errors be automatically "compensated" by re-xmits from the source, and eventually the download would be OK? Because quite frankly, I do NOT know if my important upgrade download was OK to apply to the system, given those errors!!!
Also same thing with PING errors. Quite frequent when pinging another device on my network.
2. Quite often, accessing a site will proceed somehow OK, and then things will get stuck twd the end, as if some buffer somewhere gets overloaded??? Of course, as elsewhere reported, same can often happen with com getting stuck right over the "www" part of the URL!
3. AND, of course, the often reported "NO connection to the Internet", but computer shows good signal level and connection otherwise.
4. Strangely enough, seems that the Airport Extreme wifi card sort of "warms up the the internet" as one proceeds to start using it. It eventually picks up on a network, and often "improves" its connection over time!
5. Built in Airport Extreme seems to not exhibit up all immediately surrounding networks. Sensitivity issue?? iStumbler does.
6. iStumbler permanently posts noise level of 9% regardless of how close to my wireless router/broadband modem I am. Anyone uses iStumbler to monitor network traffic?
This is getting longuish: I just want to get over all those p*ant issues and get into putting my a/v stuff together!!

Thanks for just reading all this!. I am not sure it is all fixable (back to the Win "features" terminology, really meaning "bugs"??)Thanks, BDaqua. This support forum is quite well stocked: I have been perusing all its nooks and cranies!
On the www.dslreports.com - All things Mac - forum, I spotted a couple of mentions of the following type of infromation:
link: »www.hardmac.com/news/2007-07-27/#7039
- The first TechNote provides information concerning the Airport problem affecting the MBP Santa Rosa (but also other Mac Intel). When used on battery, the wireless connection drops and one can even experience kernel panic. Apple Centers are asked not to exchange affected notebook as this is due to a unidentified bug in the Atheros driver, and should be fixed in the future with a simple Airport system update. So for the moment, unfortunate users are asked to directly power their notebook when using wireless network, or using Ethernet connection when running on battery... in other words, turn your notebook into a desktop

I am wondering if you and folks on this close-to-Apple forum know anything about this. At least, we could just await remedy instead of messing around endlessly looking for solutions and... pondering as to whether it was a wise thing to purchase an expensive machine which happens to have trouble communicating online. After all, seems that the Mac folks are prone to spend MORE time online uploading/downloading music and videos instead of my being normally doing with the rest of my (Win) computers, i.e. work on customer lists, correspondence, inventories, accounting, data bases, etc....
So, seems to me we do have a pb and Apple might just save a few $$$ on silly ads and get to work on com instead. if nothing else to avoid the appearance of further - admittedly rather funny - ad-spoofs!
So back to your further inquiry. I run a wireless network from a HughesNet satellite modem, thru a Linksys WRT54GL wireless router, into some nearby office LANed desktops and point of sale equipment, to another neighbouring facility via wireless bridge, and to my Mac laptop. Distance from the laptop to the router: 50 ft max.
It all works surprizingly very well: up to 200kbps up and 1000 kbps down (in prime time, 150 up and 600 down). OK, my set up looks complex and incurring LOTS of activity. Actually, online activity is quite minimal and well scheduled - right now I am the only machine on the network online. Otherwise, our office processes online money wiring for customers among other things.
I'll try your DNS server choice on the Mac settings first. Will report accordingly.
Thanks for everything!

New Airport Extreme802.11n &Very Odd Network&Computer Issues
Hi,
We Replaced a D-Link DGL4300 802.11G and a Airport Express M9470LL/A with the most current Airport Extreme Base Station 802.11N 2.4Ghz and 5.0Ghz Dual Band and a Airport Express 802.11N (to use with a Shared USB HP1022 Laser Jet Printer. I have contacted Apple Tech Support once regarding setup and mentioned this other ? strange issue(s)
We have broadband cable that goes to a Motorola SB5101(meets ISP specs) then Ethernet cable
from Cable Modem to Wan Port on Airport Extreme. We have multiple computers all with wireless capability 1) Imac 800mhz 874 mb ram 802.11bAirport Card 2) eMac 1.0 Ghz 1gb ram Airport Extreme 802.11bWireless Card
3) eMac 1.25 Ghz 1.0gb ram and a Airport Extreme 802.11bWireless Card* all running OSX Panther 10.3.9 *and each with 802.11B wireless cards 4) Macbook Pro bought Dec 2009 running Snow Leopard 4gb ram and 250gb HDand 802.11n wireless card 5) HP Tower xw4550 running Win XP Pro SP3 4gb ram 500GB HD and a 802.11G wireless card 6) Dell Mini Net Book running Win XP Home SP3 1ghz 1gb ram 150 GB HD and a
802.11n wireless card.
At first tried setting up the Airport Extreme with the Dell Mini as it met specs and (as of Yesterday) the Mac Book Pro is with one of our children at college but was able to set up setting up the Airport Utility and Hardware for both Peripheral Devices with the Mac Book Pro.
Then things got odd. All the computers were online (as well as two wireless "Live" capable gaming systems XBox360 and Sony PS3 , I did not check my eMac until the next day
and when I woke it from sleep (or started it) I got "You need to restart your computer"
? Kernel Panic , I ran Disk Utility, Tech Tool Deluxe, Apple Hardware Test and even Applejack. no change and while permissions were repaired Tech Tool Deluxe and The Apple Hardware Test showed no faults with anything, Tried PRAM. restart etc, then we had the other eMac 1.0ghz which has been unused since the Mac Book Pro arrived as a gift, Plugged it in , started it up, and got online, no black screen, even checked and responded to email, then restarted the (2nd eMac 1.0ghz) and the "You need to restart your computer screen came up!) once seems oh maybe, possibly its crashed, or dying out
but two side by side, No Way! , so we then isolated electrical outlets, to the extent with a 100 foot extension cord outside on our back breezeway, same thing. We even went and bought a new battery and tried it in both , no change, * Was able to shut off the airport card in safe mode, restarted and it functioned as a normal computer with airport extreme card off
*same with the 1.0ghz emac airport card off and restart and functions as a computer but no online access. We then moved one close to the Airport Extreme and hooked up by ethernet and changed the settings and Bingo no Kernel Panic Like screen and can get online, tried the other same thing! So currently the two eMacs sit side by side and we bought a long ethernet cord and it works on the table where it originally was,
I did mention this to the Apple Technician that called from Apple regarding a setup issue (as have 90 days telephone support) and he said *That there have been reports of where there are with a Guest Network (we had one set up and He had us remove it as He asked if we really needed it and I said no AND also with networks with computers with wireless cards 802.11b
and 802.11g computers on a network with the802.11n computers and a 802.11n Airport Extreme, he could not explain it any further, he suggested a possible 3rd party software incompatibilty : recent download (but have not done any on the 1.25ghz eMac and the 1.0ghz has been shut
off since Dec 2009. I am baffled , my Wife and I were seriously considering buying a new Imac to replace the 1.25ghz after the Black screen showed up, but when the other one did the same, and did the trouble shooting and then the ethernet connect we saved ourselves a lot of money (t would be nice to have a new Imac but $$ is not there)
and in the past week now (could be our ISP) our Internet connection has dropped off 4 times usually for 30-45 minutes but Friday 8-20-10 it was over 3 hours (yet our Cable TV came in) I will contact our ISP who handles both the broadband about the outages
and our cable TV has been fuzzy -grainy at times, I called Them Friday and their were no outages in our area (system wide) Now though (except with Win XP) that is our access to the Airport Extreme and Utility (it blinks orange off and on when the internet is down) the Airport Express has stayed green each time. I will contact Apple also as ?
is it the Airport Extreme (but its intermittent) channels are set to automatically if thats helpful data rather than set to a specific channel, its fairly rural where we live
I thought of buying Tiger but saw the extreme prices and I called Apple per a recent Apple Thread they did not have Tiger Retail(nor did I expect then to) but after discussing
the Emacs they said why pay so much for Tiger (and a lot are used) they said and went over both eMacs specs and I checked in detail online and called them back as it was in a "card hold" and bought Leopard 10.5.6 (as min of 512 ram, DVD drive (have a combo -drive) and a Power PCG4 which both are and I am now getting unused (non System) data off the eMac and backing it up as well and its job will be to be able to access the Airport Utility (Apple OSX Leopard 10.5.6 was $129.00 plus tax free shipping and it arrived yesterday so if settings need changed can do that (with Win XP the Airport Utility
was so different and after about 4 hours and no progress I stopped and switched to he Laptop the next day!
Has anyone experienced anything like this, I read up on both peripherals before buying and called as well to the Apple Online Store to make sure we could 1) set it up and 2) all computers specs were met to be able to a)use the network for online use and b)as well as shared printing from any and all computers and they do meet the specifications
* one last item , my Wife's Imac is also on via Ethernet, It asked for a WEP password and that was not a option in the Airport Utility set up ,only WPA-WPA2 Personal password-Security configuration
so She is not on wirelessly (though I know She has been as in the past, Her Imac was on a desk in the foyer ) That may have been with the 802.11b Apple Airport white dome and not the D-Link 802.11G router of which we had a lot of configuration issues
*I could be wrong and will read up on her specs via the Mac Tracker application or online
Many Thanks, Its so odd I did not want to leave out data etc but its a *long post and I apologize for that, I hope some one can send some light on this. On a positive avoided buying a new computer!
but makes no sense (at least to us)!

I configured the new AirPort Extreme Base Station N last week using the MacBook Pro and the PowerBook can no longer operate with AirPort on (Restart Computer message). A rep at the Genius Bar indicated that WPA2 encryption might interfere with the G4?? He recommended setting up WEP encryption, this is no longer an option using the AirPort setup assistant.
It would be very helpful to know how this original post was resolved. The G4 SHOULD be able to work with the AirPort Extreme 802.11n in theory, right?? -
Network problem with PowerMac in my office
In the office I work at we have a PowerMac - I'm not sure if it's G4 or G5 but it's the white one with the clear plastic accents. We use this computer to clock in and out because it's the only one connected via ethernet instead of wireless and you have to be connected via ethernet to use the "nFocus" system that we clock in and out on.
The problem is that the nFocus page (clock in/out page) is not loading. The internet works fine though. Can anyone help because the tech people are clueless - they are mostly student workers too and most of them don't know anything about Macs.If the Infocus software uses ActiveX for the display, then it won't run on your Mac. It could also be a java incompatibility, etc. It doesn't sound like a network issue.
