How do I use pots on my client machine to change values, from the field, on my server machine and all other client machines?

I am using Lookout 4.5, build 12, and I am having a problem concerning pots. I have data tables created for the different size sewer stations my system monitors. For each station, there are setpoints for starting and stopping of the pumps. I want to be able to change the setpoints for a station on the client file using a pot and have it change on all other machines running Lookout. I did this in 3.8 using DDE, but I don't want to use DDE anymore.
I created a pot on the client file and URL'ed it to a pot on the server. On the server I created a table with a generic member "A" named "Lead Setp" and then created a member "A1" named
"C5_1LeadSetp" then a member "A2" named "C3_1LeadSetp" and so on....
In this table I connected the generic member "A" to the Pot I created on the server, and I connected A1 to its corresponding setpoint signal coming in from the field.
On the client file I connected (in the table similar to the one on the server but with all signals for the station) the "A1" member to the setpoint signal coming in from the field, and I connected the "A" member to the Pot I created on the client file which is URL'ed to the pot on the server file.
But, when I change the value of the pot on the client file, only the pot on the server and the "A" member in the table on the server change to the value of the pot on the client. The "A1" member whose screen I am changing the values from on the client does not change! This is the last thing I have to do and my file will be completely converted to 4.0. Does anyone have any ideas?
Thanks for any responses..

Hi Jason,
If I understood your task correctly, you want to change the Setpoints on the Server DataTable using Pots from different clients. And also reflect these changes on the clients locally.
You correctly remoted the Pots on the Clients to the corresponding Pots on the Server. However, you do not need tables on your clients. All you need is Expressions on each client to the particular cell of the Clients.
So, to summarize: On the Server, the Pots write to the DataTable. And since the Pots on the Clients are remoted to these Pots on the Server, you can affect any change using these Pots. Because of the common remote source (Server Pots, i.e.) all of these Pots will always be in sync. Finally, to get the Setpoints on the Clients, just insert Expressio
ns to the Server's DataTable.
I am attaching a simple example (exmpl.zip) which does this. There are three processes -- My_Server, My_Client1, and My_Client2. I had them setup on the same machine so the paths are all process relative, but you can always change those to computer relative or absolute and move the client processes to diff machines.
Hope this helps.
Rgds,
Khalid

  • How do I make a text box solid if the value in the field is greater than 0 and do this for all recor

    Hello,
    I have several text boxes on a document, and wish to make the boxes either solid or visible if the value in the field is greater than 0.
    I am using an excel file for the data, each cell with either 1 or 0 (true or false).
    Any help would be appreciated.
    Thanks,

    Yes, I also sent an email regarding this problem.
    I am using XNET to write a custom device for PXI-8516 LIN card.
    I've attached a couple snippets showing where I've tracked the problem.
    The only error that I've seen comes from the XNET Wait vi in the timeout snippet.  I believe that error occurs because frame queued in the write snippet is never transmitted by the LIN card.

  • Point a client to get software updates from the local OS X Server

    I have an OS X Server that's serving only clients as a File Share device that I would like to use for Software Updates. There are three Mac Clients and a bunch of iOS clients. How do I use Software updates from the Server? I read the instructions on configuration but have the following questions:
    Where do I find the correct port and catalog file name?
    The instruction specify a port of 8088 and a catalog of 'index.sucatalog" in the example. Is this always the case?
    I can write to the .plist specified but cannot read from it (get an error). I can see that the file has been written and the data is correct. What's wrong?

    Apple's Software Update Server only provides updates for Apple Mac software. It does not provide updates for Mac Applications via the AppStore nor does it provide any updates for iOS devices.
    Apple's Caching Server works differently. When a Mac or iOS device on your network requests an update from either the Mac AppStore or the iOS AppStore this will then be 'cached' on the server so that next time a device requests the same update it is available locally.
    The URL for a local Software Update Server would be of the form
    http://server.domain.com:8088/index.sucatalog
    This would be written on a client Mac as follows
    sudo defaults write /Library/Preferences/com.apple.SoftwareUpdate CatalogURL http://server.domain.com:8088/index.sucatalog
    It would be read on a client Mac as follows
    defaults read /Library/Preferences/com.apple.SoftwareUpdate CatalogURL
    Note: Older versions of OS X had a version of the defaults command which did not like you including the file extension of the plist file so in the past the following would fail.
    defaults read /Library/Preferences/com.apple.SoftwareUpdate.plist CatalogURL

  • How do I delete a message I forwarded, which seems "stuck" in my outbox? (Never "sent") It's impeding all other downloads.

    I attempted to forward an e-mail on March 8, but it never actually went through.  It seems 'stuck' in my Outbox, and I can't see any way to delete it. In the meantime, it's impeding any and all other items I attempt to download.  Help!!
    Thanks,

    I ended up shutting down my system, and when I started it back up, I was able to drag the photo to the trash and delete it (I did get a message warning that my deleting the photo might negatively affect the application that was "using" it, but I deleted it anyway...it worked...and I'm hoping I didn't adversely affect another application!).
    Thanks so much for your help!

  • TS3297 iTunes puts up a message "The item you've requested is not currently available in the Hong Kong Store." I had not requested anything from the HK store at that point, and I have never used any store other than the HK one. How I can clear that messag

    I've been running iTunes on WinXP for years with few problems.  I have all my iTunes files on an external USB drive. I just bought a new PC running Win7, 64-bit.
    I connected the external USB drive to the new PC and installed 64-bit iTunes on it. When iTunes started up, I pointed it at the iTunes directory in the external drive, using Edit > Preferences > Advanced > iTunes Media Folder Location. It showed a progress bar that it was updating the iTunes Library. I signed in and authorized the new machine. I have one spare authorization.
    Then iTunes put up a message "The item you've requested is not currently available in the Hong Kong Store." I had not requested anything from the HK store at that point, and I have never used any store other than the HK one.
    When I click OK, the iTunes Store page remains blank, apart from saying "iTunes Store" in the middle of the page.
    I went to "View My Account" and pressed the Reset button to "Reset all warnings for buying and downloading items", but that doesn’t fix this particular warning. I also tried Edit > Preferences > Advanced > Reset Warnings and Rest Cache.
    But still, every time I click the “App Store” button in the iTunes Store window, the message appears. If I click the Books, Podcasts or iTunesU buttons, these display normally.  So I’m stuck with being unable to purchase apps, other than through my iPad and iPhone.
    If I move the external drive back to the XP machine, the same thing happens.  If I go to another PC - a notebook running Vista - everything is normal.
    Any idea how I can clear that message?
    Thanks for any help you can offer.

    Further info on my question above.
    I have tried re-validating my credit card, which apparently fixed it for some. 
    I have also tried uninstalling, re-downloading and installing again.
    Neither of these steps fixed the problem.

    How do I use ICloud Photo stream on one computer with two differenet Apple Id's. My husband and I each have seperate ID's but one computer.

    You have to have an iOS device (iPhone, iPad, iPod Touch) or Mac to create an iCloud account.  However, if you tell your friend to create a shared photo stream and turn on Public Website, he/she will then be able to send you a link that will allow you to view the photos on the internet using your web browser.  You would not be able to comment on the photos as this requires an iCloud account, but you would be able to view them.
    You can refer your friend to this link for assistance with this: http://help.apple.com/icloud/#mmc0cd7e99.

  • How to Create a Bootable Flash Drive to do a clean install of Lion.  I have tried to use the InstallESD.dmg but it still will not do a clean install so that I do not have to do a reinstall from the Recovery (That just re downloads and takes over 6 hours)?

    How to Create a Bootable Flash Drive to do a clean install of Lion.  I have tried to use the InstallESD.dmg but it still will not do a clean install so that I do not have to do a reinstall from the Recovery (That just re downloads and takes over 6 hours)?
    The system I'm have is a Mac-mini that had SL on it and no SuperDrive.  I have also call Apple Support and they have really have not been to much help over 1st did my up grade to Lion and Installed the Lion Server.... it lost my SSL that I paid for and kill almost on of my server setting, plus kill all my web servers (using apache vhosts), and not to say the LDAP will even let remote users login to your laptops.
    PS: There is no way that I'm going to buy a Install USB from Apple... They have over billed me over $300.00 because the Apps Store still has bugs (Glad I did not write that App/Service)
    If there is anyone that can give in the information to create a USB install stick, I would be very thinkful.

    Here you are bro, courtesy of "softpedia.com"....brilliant site!!!
    If you ever had problems with your Mac OS X installation you know that the first thing you should do is to check the startup volume using Disk Utility.
    After the check has ended and, if the errors exceed a certain level of seriousness, the Disk Utility application will require you to restart your Mac and use its Mac OS X Install disc counterpart.
    Other users may have to reinstall OS X altogether, but will find, or already know, that their SuperDrive (a CD/DVD reader and write combo drive) is not functioning properly and it will not be able to read the Install disc.
    Although this might happen to Mac OS X Leopard users due to faultyhardware, the vast majority of problematic SuperDrives will be encountered inside Snow Leopard running Macs.
    This is due to the updated SuperDrive firmware included in either the Install disc or the software updates one has to install to reach the latest version of OS X, namely 10.6.6.
    This can be fixed by flashing the SuperDrive’s stock firmware using free command line tools that one can find for free online (I will write about this process also, but at a later time because this article only focuses on allowing you to create your own alternative USB boot disc).
    If you are reading this last bit of information with skepticism, than you should know that it happened to me too. Despite all my tries to make it work properly, the SuperDrive kept on munching any inserted DVDs and just popped them out in about twenty seconds.
    The workaround to this issue was to create my own Leopard bootable USB memory stick. I am not suggesting a Snow Leopard bootable stick mainly because there are lots of users that have decided to buy the cheaper, Upgrade version, which I have not tested and, therefore, I’m not sure if it will work properly once written to a USB disk.
    And now, here are the exact steps you should follow in order to obtain a fully bootable Leopard (or Lion) Install disc.
    Step 1 (If you already have the Leopard install disc DMG file you can skip to Step 2)
    Launch Disk Utility (you can find it inside /Applications/Utilities). Here select the Leopard Install disc in the list of drives on the left and click on the New Image menu entry at the top of the window. A save message will appear where you will have to select the Desktop as a destination.
    Step 2
    After Disk Utility has finished creating the Leopard DMG, insert your USB stick and erase all data and reformat the disk. To do this select the USB in the list of drives on the left and, after clicking on the Erase tab on the right side of the window, choose the Mac OS Extended (Journaled) format and click the Erase button beneath.
    Step 3
    After the USB has been reformatted, download the SuperDuper app from HERE and launch it. Once SuperDuper starts, you will only have to select the DMG in the Copy drop-down menu, your USB memory stick on the right and hit the “Copy Now” button.
    One can also use Disk Utility for this task but creating a bootable USB stick failed 2 out 4 times when copying the DMG to the stick (with the exact same settings each time). Creating the bootable stick using SuperDuper proved to be the perfect way to do it because it worked each of the 4 times I tested it.
    The steps above can also be used to create a bootable Mac OS X Lion USB by using the InstallESD.dmg image you can find inside the Lion installer (named “Install Mac OS X Lion.app”) downloaded from the Mac App Store in the /Applications folder.
    To locate the InstallESD.dmg right click the Lion installer, select the “Show Package Contents” entry, go inside the “Contents” folder, and from there into the “SharedSupport” folder. Inside this folder you can find the InstallESD.dmg you can use to create your own bootable Mac OS X Lion USB stick. To do so, go to the third step described above and use the InstallESD.dmg as the DMG to be copied to your USB disc.
    That’s it! Once the process ends you will have a fully bootable Leopard (or Lion) USB disk that you can use as an alternative to the Apple’s DVD Install disc that comes bundled with all Macs.
    To use your newly created bootable disk you will have to restart the Mac, press and hold the OPTION key until the StartupManager appears. Here, select the Mac OS X Install disk using your keyboard arrows and press return to start from the selected drive.

    It's good to read Antoniad's post.  It reassures me that I can use my new iPad as an international communication device which is the reason I purchased the thing.  However, I called Verizon today (my provider of cellular data) who told me that I can't just pop in a SIM card as you suggested.  He also said that he was from the "Pre-Pay" division of Verizon and he was certain that I couldn't do what I planned to do.  I was extremely disappointed as I had called Apple prior to buying the iPad and I read the algorhythm on the website for choosing an iPad before purchasing.  Those sources were quite specific and the information seemed clear.  I would be able to use my iPad to communicate through cellular connections while traveling on the road, literally, abroad.  I was told that I could pop in a data card wherever I was, just as you indicated in your message above, and voila I was good to go.  The Verizon rep definitively rained on that parade, but said that I might be able to do this if I have a "Post-Pay" account, a different area of Verizon.  I haven't had the chance to talk to this division yet, so I looked to Apple's Support for answers.  Maybe I will find out that I can use my iPad as an international communication device while traveling on the road afterall, however, it appears I may need a different type of account (Post-Pay), something I was never warned about. Can I switch to this kind of account?  I don't know.  I have to find out.  If you have any information about this issue, it would be good to share since I strongly suspect there are others who bought the iPad for the same purpose that I have.

    The same way you found them to buy it - use whatever means you

    Apple cannot/will not give you the information about any previous
