TCP Connection Issues with OPC Server and GE Versamax

Hi there,
I have an installation of Lookout 6.0 coupled with the OPC Inductrial Automation servers.  In my application, we are running two instances of the GE Versamaz Ethernet driver to communicate with two remote (over the internet) GE Fanuc Versamax PLCS.
Every few days, the two PLCs lose connectivity.  It does not appear to be a LAN connectivity issue as I can still log into the PLCs using the GE software.  To fix the issue, the Lookout software must be restarted.
Has this been seen by anybody else?  This poses a significant problem as lookout is used to monitor the PLCS at sewage stations - each time the connections are lost we have to deploy technicians to the sites to ensure all is working.

Hello Andrew,
                       When the connection is terminated are you getting any errors or alarms? If so what are they? Also you can try to replace the object that is connected to the PLC and make sure it has the correct settings. It may also be due intermittent networking issues, losing connection and not able to connect with the object again unless Lookout is restarted again. I have not heard about any such networking issues. The attached document can be used for reference.
Regards,
RMM

    Hi, When you connect to NI OPC Server by creating New I/O Server > OPC Client. You will see all registered OPC Servers running on local machine or remote machine. I used KepServerEx from Kepware and LSIS OPC Server from LG with no problems. Just make sure that the OPC server is running.
    Hope it helps

  • Outlook 2011 Connection Issue with Proxy Server after 10.8 Upgrade

    Hello,
    After upgrading my MBA to 10.8, my MS Outlook (Outlook Mac 2011) mail connection does not work for an exchange based mail account where a VPN/proxy server combination is involved. This was not an issue at all under 10.7. What's interesting is that it's not an issue with MS Outlook 2010 on my Parallels VM either under 10.8. There are no internet connectivity issues, I am able to connect to the internet using Safari and other browsers. Any help would be appreciated.
    Thanks,
    Manish

    I was having a similar problem using Outlook 2011 running under Mountain Lion (10.8.2) on an MacBook Pro. When at work, behind our proxy server, I could not get Outlook to connect to a client's public Exchange server, but this worked fine without changing any settings when I was connected to our DMZ network or at home (no proxy server in these cases). My MacBook was configured to use "Auto Proxy Configuration", and Safari worked fine in all three locations (as did Apple mail)
    Today, the Microsoft Office auto-updater downloaded an update, and since it was installed, the problem has been fixed and I've been able to connect to our client's external Exchange server event when behind our local proxy server (Outlook now reports that the latest installed update is 14.2.5)

  • Wireless connectivity issues with Macbook Pro and At&t service HELP!!!!!

    I have three Computers two PC's and one Macbook Pro( the latest model).My desktop PC is used by ethernet, my girls laptop is used wirelessly and finally my MBP was being used wirelessly.
    I started off with only the two PCs and my internet connection never had a problem and I was doing everything from: on the internet to downloading.
    Before I bought my MBP I had also switched from internet and phone bundle to just internet from At&t service. So when I got my first MBP I notice that I was loosing wireless connection with both my girls pc laptop and my MBP so i thought it was because I had just switched service, though they send out a service technician and we came to a conclusion that it was the MBP. (I was loosing signal via wireless and ethernet). So we tried to see if both my girls laptop(wireless) and my PC desktop (ethernet) would run into the same issue which it did not.(MBP was turned off)
    So I decided to go my nearest Apple store and let them know what was going on. So I told them what was going on and they said It must be the airport card, and they ended up changing it. When I get home I discover that not only I am having the same issue but other issues too. I went back they ran some diagnostic and they said it was defective and they gave me a new one few days later.
    So in the mean time that I waited for my new one to arrive I used my PC desktop and my girl kept using her laptop and guess what no issue what so ever for one whole week. Now I receive my new MBP(they bumped the specs a little), went home set it up and still the same issue though I dont have the issue when Im using via ethernet. Just a view minutes ago I tried removing the ethernet and using the airport/wireless and within a few minutes I lost the signal.
    I have the gateway 2WIRE model(2701HG-B) modem/router.
    Is there something wrong? what do I have to do to make this work?

    Hi Guys, I bough my Mac almost two years ago. All this time I have experienced the same issue. There are tons of discussions re this issue in the internet. Unfortunately, Apple has done nothing to fix it. I have tried a lot of different options, but they work no longer then 1-2 days. The official fix - does not exist so far. It is quit strange, isn't? I can share my experience: if you go to AirPort Utility - Manual Setup - Wireless and then change Channel, it could help you till the moment you restart your computer; next time you need to repeat it again. It takes 2 minutes. Not sure that it would work for you but you could give it a try. Well, not the best option. Anyway Apple must fix it asap! Hello Apple, do you hear us? Good luck.

  • Anyone noted Bluetooth connection issues with iPhone 4s and Ford sync?

    My wifes iPhone 4 with IOS 5.0.1 auto connects to Ford Sync at least 75% of the time on first attempt. My new iPhone 4S with IOS 5.0.1 takes 4-5 attempts and rarely if ever connects without multiple attempts. Any one else seeing issues with failed Bluetooth connections with iPhone 4S phones?

    Look at the right panel for links to other threads concerning problems with Fords. And it's not just Fords, cars in general.  No solutions seem to be given.

  • Website issue with osx server and hosting

    so i had a website hosted from my osx server and i had bought the domain name from godaddy it worked great but i desided to instead of hosting it on my osx server to just host it on  godaddy so i turned to server off and added the domain to my godaddy account hosting and now it works but one problem all computers can veiw the website but mine. i think it has somthing to do with the fact that my mac was the one hosting it. but if i go to my browser and go to my wesite i get a error but than i go to any other computer and it works great help please

    A couple ideas
    check our /etc/hosts file, you might have an entry for your domain.
    sudo pico /etc/hosts
         do you see any entries for your domain? If so:
         edit the file by navigating with the arrow keys, delete the line
         with your domain. Hit ctrl-x when done (enter 'y' to save the change)
    Clear your DNS cache
         dscacheutil -flushcache
    Try a different DNS server, go into your network settings (In System Preferences)
    Go to Ethernet or Wifi (whichever you are using), click Advanced and under the DNS tab enter:
         8.8.8.8
    Make sure no entries are ABOVE it.
    If none of this works, send the results of these commands:
         cat /etc/hosts
         cat /etc/resolv.conf
         dig +short mydomain.com   (replace with your domain)
    The results of these should point us in the right direction.

  • Connectivity issue with iPhone 3GS and Time capsule 7.6.1

    I've upgraded the firmware of my Time Capsule. Now i have WiFi connectivity problems with my iPhone 3GS. My iMac and two iPads (version 1 & 2) are doing fine.
    Very strange in this situation is when I at a rare moments are able to connect my iphone to the wifi my iPad2 connection falls out. But after a minute or 2 the system disconnects my iphone and reconnect my ipad.
    For info: I'm using an iMac 27" 3.4 Intel Core i7 with Mac OS 10.7.3 - all software is updated.
    Thanks for reaction
    Stephan

    The iphone is very sensitive to channel selection..
    Open the airport utility manual settings.. Go to the wireless.. change its name to something simple without spaces.. TC24 would do nicely.
    Set the wireless to b/g a/n so it works with everything .. not auto.
    And set the channels manually.. 2.4ghz (which iphone uses) set channel to either 1, 6, 11.. these are the only channels that do not overlap..
    Try and see if the iphone connects..
    Set security.. WPA2 personal and put in a suitable key.. pure alphanumeric no spaces.

    Presumably you are talking about the MS SQL Server driver.
    The error tells you the problem....
    java.lang.NoClassDefFoundError: com/merant/jdbcspy/SpyLoggerSomething is not in your class path.

  • Pool connection issue with sql server database in adf application

    Hi everyone
    I'm Developing a BPM application using Oracle bpm 11.1.1.5.0
    My JDeveloper version is 11.1.1.5.0 and my database is SQL Server 2008.
    I have created a new BPM application, an application module and created several view objects based on my sql server tables in the database.
    I have only one initiator user task which has a task flow and one jspx page for that.
    The problem :
    when I deploy the application, in the bpm workspace initiator page, the page is shown correctly only once every other time.
    I mean it's strange, the first time the user instantiates the process, it's shown correctly. The second time, it is not! The third time, it is! etc...
    The interesting part is, when the page is not shown correctly, if I refresh the page it will be shown correctly.
    Here's the log output from when the page is not shown correctly:
    JBO-30003: Application pool model.sam.specialAppModuleLocal fails to check out an application module due to the following exception:

    Hello thank you
    I found the file and changed the SQL Flavor to SQL Server but it still shows a blank page with the error instead of the page every once in a while.
    The error has changed though, now it is like this:

    I have noticed that this time only if the user submits the page, the next time he/she initiates a new task the error appears.
    Do u think this has to do something with pool settings or session settings or something like that?
    Thanks again

  • WRT400N connection issues with iPod Touch and MacBook

    I'm a newbie, so please bear with me.
    I recently upgraded to the WRT400N from a Linksys BEFW11S4. 
    Since the change, the connection to iPod Touches and MacBooks at the house have been shaky at best.  The connection frequently drops out completely on the iPod Touch even if it's right next to the router.
    I've tried resetting the router, changing settings on the iTouch and MacBooks, but the problem persists. I don't want to mess with the router settings as I'm not experienced in that area.
    Can anyone please help me?
    Thank you.

    You can try the below mentioned settings.
    Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1 and press Enter...Leave Username blank & in Password use admin in lower case...
    On the set-up tab change the MTU Size to 1365 and click Save Settings...
    Once you return to the set up page click on the Security tab and uncheck Block Anonymous Internet Requests and click on Save Settings...
    Click on Advanced Wireless Settings
    Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304 Change the RTS Threshold to 2307 >>Click on "Save Settings"...
    Now see if you can locate your Wireless Network and attempt to connect...
    This should fix the issue for you.

  • Sybase  Connectivity Issues with OC4J Server

    I am trying to access a Sybase Database using JDeveloper.
    I have downloaded the sybase Jconnect product(version 5.5) and am able to access the database through the IDE.
    I have created a test jspx document to validate the DB connectivity. When I attempt to run the document. I am getting the following error from the OC4J server: javax.servlet.jsp.JspException: Unable to get connection, DataSource invalid: "java.sql.SQLException: No suitable driver".
    The document code is as follows:
    <sql:setDataSource
    dataSource="AgileSCM"
    driver="com.sybase.jdbc2.jdbc.SybDriver"
    password="password"
    url="jdbc:sybase:Tds:server_name:4002/db_name"
    user="uer_name" var="myDs"
    scope="session"/>
    <sql:query var="company" dataSource="myDs">
    SELECT * FROM dbo.company
    </sql:query>
    I am new to using Jdeveloper so I would appreciate any help.
    Thanks,
    Brian Muraco

    I created a db connection called AgileSCM in JDeveloper which is accessing the Sybase database. I tried coding the document with and with out specifying the datasource with the same result. Am I not doing something really simple?

  • Connection issues with MacBook Pro and DVI to component video

    How do I connect a 2007 macbook pro to a regular tv (non-hd) via the DVI port with component cables? The image is always scrambled. The connections are fine, what do I need to do?

    Concerning this comment:
    I know that neither the adapter nor the VGA cable have a problem since I connected the computer to my 1080p TV and it worked just fine...
    I would like to point out that 1080p has a lower pixel clock than will 1920 x 1200. So it could be the stability problem is only present when the pixel clock is at the high end of the range.
    You could return the adapter and try another. A new one might have better margins. Another thing you could try is to use a utility like SwitchResX to lower the pixel clock and see if stability improves.

  • Having connection issues with my E2500 and my laptop(now with an AE1000).

    Ok, here's the story.  Just bought and set up an E2500 Router, no problems.  Connected my laptop to and everything seemed to be running fine.  Here's the problem.  The router is on the second floor.  When my laptop is under it, 5 bars.  When I go one room over, it goes down to two bars.  So, I buy the AE1000, connect that and same story.  Now a little history on my laptop.  It is a Dell insipron 1720 and it was running vista until I upgraded it to Windows 7.  I would appreciate any and all advice.  THANKS!

    The concern is that you are getting poor signals…. Let me know how did you install the Router – means was configured with the help of the Cisco Connect Software or did manual configuration? The concern that you have for that if you have to do the following settings…
    If you have configured the Router with the help of the Cisco Connect Software then you have to open that up in which you have installed… There you will be able to see 4 small window screens…
    You have to click on “Router setting” window…
    Then click on “Advanced settings” button… That will open the Router Setup page then click on Wireless Tab and make the following wireless channel-
    For Channel Settings of 2.4 GHz you have to make the Channel Width to 20 MHz only and Channel to 6, 9, 11...
    For Channel Settings of 5 GHz you have to make the Channel Width to 20 MHz only and Channel to 40 or 161...
    Then check the connectivity…
    If you did configure the Router manually then would have opened up the browser and on the address bar would have typed 192.168.1.1 that would have opened the Router setup page… From there you would have done the same steps as above…

  • TS2972 Connection Issues with Macbook, iMac, and Apple TV 3

    I have an Apple TV 3 (ATV3) and my iMac connects via Home Sharing just fine, but my MacBook running 10.6.8 doesn't show up, nor does it recognize the iMac in iTunes. All devices have Home Sharing turned on using the same AppleID. Any thoughts as to why my Macbook seems to be the odd one out?

    I had this problem earlier and was able to solve it by checking the display setting in the System Prefrences. This link will help you. http://documentation.apple.com/en/aperture/usermanual/index.html#chapter=B%26sec tion=4%26tasks=true
