Communicate with two DCs thanks to Events
Hi everybody,
So My question is about the events between two Development Components. I can't communicate to both DC !
I followed each steps of the tutorial <i>Using Server-Side Eventing in Web Dynpro Components</i> but something is missing because it doesn't work.
This technique work well inside my component (I can fire plenty of events without problems).
After debugging, I saw my program going into the interface and then fire the event. But nothing catch it.
Do you have any idea ?
Thanks.
Hi,
I didn't solve my problem. There is something weird in the behavior of my application. Because when I make the event process all worked well. And the next day it does not work anymore
I tried to do it again with two new DC and it work well. I'm getting crazy with WebDynpro !!!!
About your solution, my customer do not have the portal so I can't use the iViews Event.
Thanks anyway

Can I communicate with two different FP 1000 modules through one labview program at the same time
I am wondering could you communicate with two seperate FP 1000 modules with one labview program, using a tab control, with page 1 of the tab communicating with one FP 1000 through com port 1 and page 2 of the tab control communicating with another FP 1000 module through com port 4, using different iak files for both. Can I do it through using those wireless modems supplied by National Instruments. Sorry I dont have a name for them.
Noely,
Within a single IAK file, you can have multiple FieldPoint modules on separate COM ports. There is no need to use separate IAKs for the program you are describing. Actually, older versions of NI-FieldPoint do not support having multiple IAKs in use simultaneously (I am not sure whether it is currently supported).
As for the Radio Modems, they are called SRM-6000s and can be used simultaneouslyon different serial ports. Although, using the SRM-6000 in a single master multi slave arrangement, you could use a single serial port to talk to both FP-1000s (3 SRMs total). You will need to configure the FP-1000s to have separate addresses (DIP Switch setting).

The two bits of the program will talk to each instrument successfully if the other part of the program is not running. i do not need them to communicte with both serial ports at the exact same time, just within the same program, one after the other. i am using labview 6. any ideas of what i could be doing wrong?
Hello,
If you are using the Legacy serial VIs, you should really switch to the VISA VIs. Also make sure you are opening a session to each of the com ports at the beginning of the program and closing each at the end of the program. Problems can arise if your try to open a session to a port that already has a session open. Also you should update LabVIEW to 6.0.2
If you are still having problems post the error code and error message you are getting.

I am a student. Just started with Labview. hence, any sample VIs will be of real help to start with.

Hello,
I want to communicate with two device (up to twelve). The problem is that the documentation of my device is very badly written (DSP9000 from Riber if you want to know). It says that for a network communicating I should write for an commands : EOD GID GID UID UID STX MN1 MN2 <command> ETX BCC (for example "r off" is a command). When I write on one device only I use the attached file (ex.vi).
Someone can Help me ?
Lab 8.0
If some information miss please leave me a message
Thanks,

ex.vi 23 KBThe first reason your code won't work is that the string you are sending is "@ABCDEF" which means nothing to the controller. You have to send the string of characters that are formatted on page 18 of the manual you attached. I am not sure if you looked at my example code at all.
Your string control is labelled as "String (HEX formatted ASCII" but is actually just normal display with hexadecimal digits and spaces. As a result you are doing a lot of manipulation of the characters to convert them to hex codes. All you need is a string control that has its properties on the right click menu set to Hex display. Then you can type in the hexadecimal string and use the string as is.
I am reattaching your VI with this control set to the example string shown on page 19 of the manual. Try this to start.
Then the question will be are there just a few commands you will execute which you can predefine the string to send along with its checksum character, or will the VI need to be more flexible to send any kind of command. If the latter, you will need to code how the block checksum character is calculated. You would also have to concatenate the special control characters together like I did in the example I attached earlier.
I would also recommend that you attached a serial read function so you can see what response you get back from the controller. If you are still having problems, double check your serial port settings of baud rate, parity, data bits, stop bits.
Also check your wiring. Your subject says you are using RS-485. Is it 2-wire or 4-wire? The manual is a little cryptic in that it starts talking about RS-422 on page 21. But on page 22, lists the RS-485 2-wire and 4-wire setups. But it never truly shows the full wiring of an RS-422 setup.

hi all
I am designing a report which has two pages , i completed first page, i need to insert second page
how to design report with two pages
Thanks in advance
KrishHi,
Usually,any report automatically adjusts its page numbers as per the quantity of data that needs to be displayed.However, if your specific requirement is to show certain data on one page and the remaining on another then you can simply insert a group on a valid field.
Following is some information from the Crystal Reports Online Help menu:
New Page After:
- When the End of Section check box is selected, the program inserts a page break after the section.
- The Page Header and Page Footer appear on each page.
- Use New Page After in the Group footer section to print each group on a separate page.
May be, if this is not what you are looking for then please elaborate on the report design/data -
Why can't I communicate with both of my GPIB devices?
I have 1 NI PCI GPIB board in my computer
I have 2 identical devices (keithley 237) connected one at address 15 one at address 16
and 2 different programs one program to connect with 15 and 1 to connect with 16
after I tell the 1st labview program to communicate with 15 then I tell the 2nd labview program to communicate with 16. then both communications come back with error device timeout. one at a time, I can communicate find with either device.
Why can't I communicate with two different GPIB devices at the same time?Hi mrutter,
first I would try some other addresses, e.g. 5 and 11. 15, 16 could be
a special address used by the controller.
Are there any other devices on the GPIB? If so then there could be
another instrument with the same ID. Do both (or all) devices show in
MAX, and can you communicate with them in MAX (e.g. query a *IDN? )
And are you sure that you *have* setup the correct addresses in the
Keithley instruments (look in the manuals if you don't know how to
change their addresses)? Some Keithley instrument are in local mode by
default, and you must explicitely set them in GPIB mode.
Sometimes, GPIB message termination can be an issue (although both the
GPIB cards and the instruments seem to get more tolerant of this).
Also, you must be very careful not to mix different versions of
LabView drivers and LabView version. I once had three different
LabView versions on a PC, it was terrible. We had to format the
harddisk and start afresh since we couldn't remove all of the older
versions.
I first try all GPIB instruments in MAX. If all devices appear there,
and I can query commands in MAX, then I usually write my own LabView
drivers with the standard GPIB-read and -write VIs. I write them with
my oldest LabView version (say 5.1), then I am sure they will work
with all versions up to 7.1
Actually I once had a project where *no* GPIB instrument worked 100%.
We could never really find out what was the problem (it was probably a
bad PC <-> Win98 <-> GPIB card <-> LabView 5.1 constellation).
Good luck.

I can't comunicate with two fieldpoint chains from one pc
I have two separate labview programs which use different serial ports (com8 & com9) to communicate with two separate sets of fieldpoint hardware. Each works fine on it's own. When I run both from the same PC, the second to start always receives a 'Can't bind to com port' error from the FP create tag.vi. Both programs are using different .iak files which only reference their own com port.
The FieldPoint Server, which is launched wheen you run the FP Open.vi can only have on instance running in memory. You can not have multiple servers running simultaneously, which is what your programs are attempting to do. Merge both IAK's into a single IAK that each program will access. Each Comm Resource (one for Com8 and one for Com 9) should be given a unique name.

How do I enable two wireless clients to communicate with each other?
I have a WRT54GL with the latest firmware. I have two computers which are both connected to the router, with IP addresses assigned via DHCP. Neither has a firewall running. I cannot get them to communicate with each other -- even ping doesn't work. I can ping the router itself using the IP address assigned to it on the WAN side by my ISP. Both computers have no problem reaching the internet through the router.
What settings on the router will enable the communication to occur? I can't find anything in the router's user interface which appears to control this.
Thanks.
Solved!

I think it would be best to check on netgear or belkin technical forums how to make these two talk.

me.com accounts can be used for iCloud. See the FAQ section in:

I have a carillon 25 keyboard (bad choice, I know) and I can't get it to communicate with my mac at all! I'm running logic pro 9 and reason 5. I get signal in from my M Audio trigger finger so I know it isnt an entirely mac based problem. Thanks!!!
Well, how have to determined no signal is being recieved to your mac?
Have you got something that shows the actual signal? Or have you just been trying to control a VST? What software are you using by the way?
I personnally went with a AKAI MPK25, because it's made already mapped for logic & ableton etc, so it just makes things incredibly easy.
I would suggest you return it if you can as a dead unit & perhaps look at something else a bit easier?
Otherwise, if you just want to get this working we can have a look a bit deeper.

Hi Everyone,
I have a program that sends information(analog output) to lab windows cvi in the form of a text file or user input.
The program runs on the computers that I have the field point explorer and lab windows cvi installed on. In order to run the program without always installing labwindows/cvi and field point; I wanted to create an executable file that could be load on another computer.
I used the create distribution kit part of labwindows/cvi to do this.After creating the distribution kit, I then installed it
to another computer.
My user interface appears on the screen, when the user clicks on the exe. file, but no data is sent to the field point module. I know that the data is being read from the user and textfile because in it appears in the uir.
The following are some details about the problem:
1. On another computer without labwindows/cvi and field point explorer not installed - no data is sent to field point module
I know this because a current is being read on the current meter connected to field point module.
My questions are the following:
1. What are the possible reasons for the data not being sent to the field point module?
2. Do I still need to create an iak. (Installing Field point Explorer) file stored on any new computer that I install my created distribution kit file too?
Thankyou very much for any help that you can provide. I greatly appreciate it.
Faen9901Re: Hello, I have created a distribution kit for my program.The problem is that the when the program is installed onto another computer, it fails to communicate with field point (Using FP-AO-200 and FP-AO-1000). Help is greatly appreciated, Thanks faen9901Faen9901,
1) If you do not install FieldPoint Explorer, the FieldPoint Server is not installed so there is nothing on the target computer that knows how to talk to the FieldPoint system.
2) Yes, you need an IAK file on the target computer. Assuming the settings (i.e. com port#) are identical you can simply include the iak file as part of the distribution.
3) You also need to include as part of your installer the file "fplwmgr.dll". If this file is not installed, your program will not be able to access the FieldPoint Server. Alternatively, this file is installed automatically if FieldPoint Explorer detects LabWindows/CVI or Measurement Studio Development versions on the target computer or if you choose to do a custom FieldPoint Explorer installation and
choose to provide LabWindows/CVI support.

I am not very tech savvy, installed Firefox and it won't communicate with my Incredimail. If I click on a link in my email it does nothing. ie: if i click on the pay now button on ebay or paypal it goes nowhere. also is there a way to transfer all my favorites/bookmarks from IE to firefox. I've heard Firefox is so much better than IE but I am getting frustrated (probably out of my own ignorance of the program) and ready to go back to IE. Please help! Thanks. Jeanne
I cannot help with Incredimail, but I do know how to transfer bookmarks.
One can use File > Import from the menu or export favourites from IE as .html and then import the file into Firefox from the "Show all bookmarks" window. To get the menu to show up, press Alt. Firefox should have offerecd to import several items from IE when you first set it up. Did it not do that? -
Migration between two environments which can't communicate with each other
My customer is intending to do migration from test environment to production environment using CCM.
But the two environments are not in the same network.
The environments' setting is as blew.
BO TEST Repository can communicate with Web BO Server.
BO PRODUCTION Repository (Cluster environment) can communicate with Web BO Server.
BO TEST Repository and BO PRODUCTION Repository (Cluster environment) are in the different network, they can't communicate with each other.
Setting Target Repository manually in CCM.
Questions are:
1. In CCM, as long as both Source Repository and Target Repository can communicate with Web BO Server, the migration will be successful.
Is that right?
2. If 1 is not right, is there additional setting should I do?
For example, If I need to open some firewall port?
3. Is there other attentions should I notice?
ThanksQuestions are:

Yes that is correct
2. If 1 is not right, is there additional setting should I do?
For example, If I need to open some firewall port?
You have another option which is to use the BIAR files. Export your objects to a BIAR file in source environment, and import them from BIAR into the target environment
3. Is there other attentions should I notice?
when using BIAR files as solution, Make sure that you keep them < 1GB size to avoid corruption
you may have to increase or adjust timeouts on input and output repository servers as well -
I can't connect to iTune Store nor to radios, with the aid of iTune,check for updates, these last two from aid, but if you communicate with support.Please the answers in spanish.
Back up all data.
Unlock the Network preference pane, if necessary, by clicking the lock icon in the lower left corner and entering your password. Cllck Advanced, open the DNS tab, and change the server addresses to the following:
8.8.8.8
8.8.4.4
That's Google DNS. Click OK, then Apply.
In Safari, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. If you’re using another browser, empty the cache. Test. Any difference?
Notes:
1. If you lose Internet access after making the above change to your network settings, delete the Google servers in the Network preference pane, then select the TCP/IP tab and click Renew DHCP Lease. That should restore the original DNS settings; otherwise restore them yourself. Remember that you must click Apply in order for any changes to take effect.
2. I don't use Google DNS myself, though I have tested it, and I'm not recommending it or any other DNS provider; the server addresses are offered merely for testing purposes. There may be privacy and technical issues involved in using that service, which you should investigate personally before you decide whether to keep the settings. Other public DNS services exist.
