FPGA with HDL node

I am using a PCI-7831R. I have a VI that is basically putting out data into a board that we aare devoloping. I also have a HDL node as another VI that looks at frames sent out from another board and picks out words from certain locations in the frames. I want to know if I can run this HDL node VI along with the other VI. Thanks
Bibin

Hello Bibin,
You should be able to run both VIs at the same time if you place them in parallel inside a bigger Main VI. So, both VIs will be running as subVIs.
The only restriction would be if they were talking to the same IO channels.
Hope this helps.

HDL node not picking up push button signals

Hello,
I am trying to design a vending machine using sbRIO and Labview HDL node. But my HDL node doesn't seem to pick signals from push button (latched when released). I have successfully done the same thing using labview blocks but not geting desired results by HDL node. I could use labview blocks only and not HDL node but I have to give a presentation to my class about how we can integrate VHDL code in labview. I have attached my VI with following VHDL code living inside HDL node.
process( clk, reset )
begin
if( reset = '1' ) then
state_reg <= idle;
enable_out <= '0';
elsif rising_edge(clk) then
state_reg <= state_next; -- result and enable_out follow input by 1 clock cycle
if( enable_clr = '1' ) then
enable_out <= '0';
elsif( enable_in = '1' ) then
enable_out <= '1';
end if;
end if;
end process;

Thanks, NapDynamite. However, you just included your Project (not the actual VI) on the attachment. A good way to include all of the dependencies is to create a source distribution (LLB).
Right-click on Build Specifications, select New»Source Distribution
Under Distribution Settings, select Custom as your Packaging Option
Check the Destination is LLB box and click OK on the warning.
Choose the Destination Path where you would like the LLB to be saved
Click Build to create the LLB, or click OK to save the Build Specifications.

R12 with 2 node 10g RAC is not updating with autoconfig correctly.

Hi,
we are on R12.0.6 with 2 node 10g RAC. Our collegue did the RAC setup, I was not there at that moment
steps he followed is
1. Installed 10g CRS,ASM 10.2.0.3 software and bring up the two nodes.
2. Configured the RAC DB to Oracle Appplication and registered the Listener with CRS.

Vasu,
The issue is, in our tnsnames.ora in both the nodes.What is the issue?
I believe the following documents should be helpful in configuring your tnsnames.ora (and other files) with RAC implemented.

Weird bug with desynced nodes - including demo and screencast

This is a follow-up to Desync of Elements and logic - how to debug?
I started a new thread because I will provide better information on this.
So we've made our graph editor working with JavaFX. One of our common demos for different products is a organizational chart demo. This is a tree-like graph with employees as nodes to depict the hierarchical structure of companies.
You can try this demo here (jre7u6 with JavaFX 2.2 b17 required):
http://www.yworks.com/products/yfilesfx/OrgChartDemo/OrgChartDemo.jnlp
We have also made a screencast which can be viewed here that shows the usage and most importantly the problem we are facing with JavaFX here:
http://www.screenr.com/uEF8
The startup is quite slow, it takes a few seconds for the graph to load. This is because the visual representation of the nodes is described within (nested) fxml files and each of those files is loaded in a not so effective way (because it is at the moment not possible in JavaFX to define a custom BeanAdapter in the FXMLLoader that does proper caching). After those files are loaded, there are still some ClassNotFoundExceptions thrown in the background by some part of the JavaFX framework I did not identify, yet. After a few seconds the performance speeds up significantly.
What you can do in this demo is described on the right. Basically you can zoom in/out, fit view, center a certain employee and interact with them.
Interaction means you can collapse and enlarge certain parts of the graph. For example, you can hide all subordinates of an employee and show them again.
The part of "showing them again" is done with an animation effect that is implemented in our framework, not in JavaFX.
When you hover an employee, a fading translation is played as a hover effect and some buttons appear. This part is important so i wanted to highlighted.
The hover effect is triggered by a onMouseEntered and onMouseExited event.
Also you can focus a certain employee by clicking on them. When clicked, the color changes from blue to orange. This is done by our internal logic, since the clickable things on the screen are not the JavaFX rectangles and such but rather a logical representation of a node with a position on the screen and a with and height.
So this is where things go wrong and what is really crucial for our application:
When you collapse/enlarge nodes (employees) a bug appears quite frequently that causes the internal representation and the actual appearence of JavaFX elements on the screen to be out of sync. Most notably the hover effect doesn't work anymore: The node is visually present (as you can see it) and the values of the nodes in the scenegraph match as well, but those nodes just are not present any more for any events. They do not receive mouse entered/exited events, hover-events and pressed-events and so on. You can still click on the node and focus it, but this is done in our framework (indicating that our logic works).
The connection of the logic and the javafx controller is done via databinding. The controller listens to changes in the corresponding model item and updates itself accordingly - you can see it when clicking on a node, the selection state of the model item changes and the controller updates the style of the javafx node.
The other effects however, like the hover-effect, are implemented on databinding on properties of the JavaFX node class: hoverProperty, onMouseEntered onMouseExited and so on.
Once a node is in this state, weird stuff is happening. For example, a node that is in this state seems to have normal values when viewed in ScenicView. However, when changing some values, for example translateX / Y, the node just disappears. (see also: http://www.screenr.com/lYF8 where i recorded that (a bit later in the video))
For an example of this have a look at the link to the screencast above. We showed how to reproduce the bug there.
We noticed that without any animation played this does not happen. So it seems to be caused by the animation. This is itself quite surprising, because we used the same animation process with other javaFX applications but never experienced this bug.
What happens is that our Animator sets the layoutX and layoutY values of a node that is being animated repeatedly and in rapid succession over a period of time.
The only thing we can think of that might cause this problem is that JavaFX somehow is not able to process a large amount of such update-calls and throws some exception internally and just dies.
Because of this we strongly hope that somebody can point us to were we have to look or how to even debug this problem.
* edit: added second screencast for ScenicView

I use the swing version embedded in Idea and the diagrams are really nice => everytime I make a printout I get asked "what tool did you use to generate that diagram?".:D thank you very much.
Only real advice I can offer is something you almost certainly know =>
JavaFX is a singlethreaded UI framework.
Ensure that anything you do which could read/write from nodes in an active scenegraph be done on the JavaFX application thread.I just double checked this and unless Platform.isFxApplicationThread() returns a wrong value, the only interaction with JavaFX nodes is done in the JavaFX application thread.
I think your app issues will prove very hard to resolve through this forum. Nicolas Lorain is the javafx product manager, so you could try contacting him directly for support. There is also some kind of JavaFX partner program which may be able to offer support as well, Nicolas should also have details on that.
Good luck with your app.I just searched for the JavaFX partner program, and couldn't find anything ongoing. The only advanced support I could find is the Oracle Premier Support, which at this point isn't suitable for us. I also couldn't find any contact information for Nicolas Lorain (he has a blog and twitter but I cannot find his email). So if you could point me to somewhere, I'd be very glad.

OBIEE 11g (11.1.1.5.0) - Issue with starting Node Manager

Hi,
Have anyone faced an issue with starting Node Manager in OBIEE 11g (11.1.1.5.0)? OS is 64 bit Linux, WebLogic is 10.3.5. I used the software-install method and followed by running config.sh. Everything completed successfully. I updated the catalog and rpd location in the FMW control screen.

Hi,
There are Two types of Cipher suites --- Certicom Cipher Suite and SunJSSE Equivalent Cipher Suite. And with Weblogic 10.3.5, you are using Sun JSSE Cipher Suite, and by default Node Manager uses the Certicom Cipher Suite.
In the nodemanager.properties, Add CipherSuite=SSL_RSA_EXPORT_WITH_RC4_40_MD5, save and restart Node Manager.

Error when executing VI with "Invoke Node" in loop

Hello,
please check if this is possible what i am doing here or if there is a better way to do it.
The goal is to have a VI that i can start in TestStand which is then running in a loop until i set a global variable.
I do this currently with:
1.) Starting the VI with "Invoke Node" (see screenshot 01)
2.) This Vi is then running all the time in a loop until the global for exiting is True (screenshot 02)
3.) Then i have another VO to set the Quit-variable to true
Normally this works as it should, but sometimes i get the error-message:
Invoke Node in NameOfTheViCalledInTestStand.vi
Method Name: Run VI
VI Path: NameOfTheViThatContainsTheInvokeNode.vi
LabVIEW: Das VI befindet sich in einem für diese Operation unzulässigen Zustand.
The question is: what does this error mean and what better ways are there to do what i want to.
Perhaps for better understanding, the VI which runs in a loop executes dll-functions to enable and disable an ample-tower to make a light blinking.
And because there is no function "blink", i have to make it on off on off on off....
So the vi loops and makes on off until i say "quit" then blinking stops.
Thanks for any ideas

02_ViRunsInLoop.jpg ‏23 KB

I cant´t do this "Try changing the "Run" node
to "Wait Until Done" = True." because then the TestStand-Step is
hanging until the loop is finished.
I only want to start the "blinking" and the continue normally in the sequence.
To
avoid that the vi with the "Invoke Node" is started twice a have a vi
above it whick checks with the globalVariable "IsCurrentlyBlinking" if
the start is allowed.
If IsCurrentlyBlinking= True then nothing happens.
So normally it can´t happen that it starts twice. Only if the GlobalVariables are not correct.
The
variable "IsCurrentlyBlinking"is set to TRUE in the subvi before the
loop starts and after the loop is finished its set to FALSE in the
subvi.

FPGA I/o node

Hi, I was wondering if the following FPGA I/o node acquires Mod1/AI0, Mod1/AI1, Mod1/AI2, and Mod1/AI3 simultaneously.
I mean I don't know if they are at the same time or not.
Solved!
Go to Solution.

I checked out the specifications of the module NI 9234, as in the following figure.
As shown, for this module, all the four channels are sampled simultaneously.
Now I'm sure!
I think for every module, we should check out the specifications to make sure.

Labview fpga with nexys 2

hi my friends I want to know I can use labview FPGA with nexys 2 and there are some device about this FPGA (nexys 2) because we have this circuit board and we want to do the project with labview you can found some information about nexys 2 in this file and thank you for your help

Hello,
As this forum thread states, LabVIEW FPGA is only for the SPARTAN-3E XUP Starter Board and NI Reconfigurable I/O devices. Even though the nexys 2 is based from the Spartan 3E, we can’t be sure that the driver that we release for the Spartan 3E starter board works for the nexys 2.

Search with "Current Node + All Subfolders" not functioning correctly

Hi,
We are having an issue with the search function of SCCM 2012 Admin Console. We have built multi-level folder structure to SCCM which matches our organizational unit structure in AD.
The issue occurs when trying to search with "Current Node + All Subfolders" option in a folder to get listing of all collections nested in the structure. As a result we get incomplete list of collections and majority of them are not showing
up. Sometimes the console even crashes when trying to do this kind of search. Note that this behaviour only occurs when searching inside a folder, not in the device collections root node.
We managed to trace the SQL query in the above situation from SMSProv.log, and it is as follows:
select all SMS_Collection.SiteID,SMS_Collection.CollectionType,SMS_Collection.CollectionVariablesCount,SMS_Collection.CollectionComment,SMS_Collection.CurrentStatus,SMS_Collection.HasProvisionedMember,SMS_Collection.IncludeExcludeCollectionsCount,SMS_Collection.IsBuiltIn,SMS_Collection.IsReferenceCollection,SMS_Collection.LastChangeTime,SMS_Collection.LastMemberChangeTime,SMS_Collection.LastRefreshTime,SMS_Collection.LimitToCollectionID,SMS_Collection.LimitToCollectionName,SMS_Collection.LocalMemberCount,SMS_Collection.ResultClassName,SMS_Collection.MemberCount,SMS_Collection.MonitoringFlags,SMS_Collection.CollectionName,SMS_Collection.PowerConfigsCount,SMS_Collection.RefreshType,SMS_Collection.ServiceWindowsCount from vCollections AS SMS_Collection where (SMS_Collection.SiteID
in (select all Folder##Alias##810314.InstanceKey from vFolderMembers AS Folder##Alias##810314
where (Folder##Alias##810314.ObjectTypeName = N'SMS_Collection_Device'
AND Folder##Alias##810314.ContainerNodeID in
(16777237,16777374,16777384,16777385,16777375,16777376,16777377,16777378)))
AND SMS_Collection.CollectionType = 2) order by SMS_Collection.CollectionName
From this we noticed that not all ContainerNodeIDs are searched, but a list of only 8 ContainerNodeIDs. These ContainerNodeIDs remain the same if the search is done again in the same folder. The same behaviour repeats also in other folders with a different
list of ContainerNodeIDs.
For clarification I'll attach a picture which shows our folder structure with ContainerNodeIDs and ParentContainerIDs. We have also marked the containers which were present in SQL statement. From this you can clearly see there should have been far more ContainerNodeIDs
than listed in the SQL query. Is this a bug in the admin console or could this be a problem with our site database? Is anyone else experiencing similar issues? We have written a custom
powershell script that reads containers from SMS_ObjectContainerNode WMI-class recursively and is able to return complete list of folders and their subfolders, so we assume that our site database and WMI on site server is functioning correctly.
We noticed this on CU2 (could have been present also earlier) and updating to CU3 did not fix the problem. Currently we are running SCCM 2012 SP1 CU3 with one primary site. All components besides distribution point is running on the site server. Distrubution
point is running on a separate server. Our SQL server is running on the site server.
Best Regards,
Juha-Matti

Sorry for the very long delay. I created the ticket in the autumn of last year and just received the final verdict to this issue.
Microsoft support said they were able to reproduce the problem and that they contacted the product group about this issue. It turns out that this behaviour is by design (wait, what?) and since it is by design there is nothing they
can/will do about it.
So the only choice is to request a tailored customization for SCCM2012, which probably in this case (as it is by design) would cost.
I feel a bit puzzled: how can it be by design if it clearly does not work?

TT bi-directional general workload architechture with 3 nodes

Hello Experts,
We are starting a new project where we will have a cluster with 3 nodes. We will have both our application and TT running on each node.
Then we will have a switch doing the application load balancing between the 3 nodes of the cluster. Whenever a request reaches one of the cluster nodes, the application queries/updates the local TT installed in the same node. All the changes made in one of the TT instances must be immediately replicated to the other 2 nodes.
My questions are:
1) Does TT supports a 3 nodes bi-directional general workload architecture?
2) According to the documentation, a bi-directional general workload configuration should not be used with the return twosafe return service. Can we use the bi-directional general workload configuration (on a 3 nodes cluster) with a return receipt configuration?
3) Since we can not use the return twosafe configuration with the bi-directional general workload architecture, how long (in avarage) dos it take for an update in one of the 3 TT instances to propagate to the other 2 instances ?
Thanks in advance,
Marcos Ortiz

Hi Michael,
1. Yes, TimesTen supports a three node multi-master general workload architecture. However, we absolutely do not recommend use of such an architecture as it has many inherent dangers. You will almost certainly suffer from datastroe divergence with such an architecture and also recovery of a failed datastore back to a state consistent with the othyer datastores will be extremely difficult. I owuld urge you to consider alternative architectures that do not require N-way mult-master where N > 2 (and even then you must enforce strict workload partitioning to ensure that consistency is maintained).
2. You cannot use RETURN TWOSAFE with multi-master since you will almost certainly encounter distributed deadlocks which TimesTen does not detect nor resolve. You can use RETURN RECEIPT in multi-master configurations but of course this offers a lower level of assurance than twosafe.
3. It is impossible to give some specific figure for how long it takes for replication to occur with RETURN RECEIPT since there are many variables. Typically replication occurs within a few milliseconds, dep[ending on configuration, but any number of factros such as sudden high system load, network glitch etc. etc. can cause it to take significantly longer. All you can say for sure is that if a commit using RETURN RECEIPT returns succesas then the replicated data has arrived at the remote datastore and is in the 'apply queue'.
Without wishing to labour the point, the architecture you are considering is highly problematic and is one we strongly recommend customers avoid. Using conflict resolution is not a solution as it cannot detect or resolve all possible conflicts and you swill still have divergence and recovery issues.

Oracle SQL - Extracting clob value from XML with repeating nodes

Hi All,
I am attempting to run SQL on a table (called test_xml with a column xml_data [data type xmltype]). The column contains xml with repeating nodes (description). The following statement runs successfully when the node contains data of a non clob size:
SELECT
extractvalue (Value (wl), '*/description')
FROM test_xml
, TABLE (xmlsequence (extract (xml_data, '*/record'))) wl
but fails when description node contains a lot of data:
ORA-01706: user function result value was too large
I amended my query:
SELECT
extractvalue(Value (wl), '*/description').getClobVal()
FROM test_xml
, TABLE (xmlsequence (extract (xml_data, '*/record'))) wl
but this fails with:
ORA-22806: not an object or REF
Thanks in Advance

Hi Greg,
11.2.0.2.0 (Although I will need to do this on my work instance also which is 10.2.0.4)That's gonna be a problem...
Direct CLOB projection is supported starting with 11.2.0.2, using XMLTable or XMLCast/XQuery functions (extractvalue, extract, xmlsequence are deprecated now) :
SELECT x.*
FROM test_xml t
   , XMLTable(
       '/*/record'
       passing t.xml_data
       columns
         description clob path 'description'
     ) x
;On prior versions, implicit conversions will occur to VARCHAR2 datatype, hence the limitation observed.
AFAIK you have two options on 10.2.0.4 :
1) Using Object-Relational storage, with the xdb:SQLType="CLOB" annotation.
2) Using the following trick :
SELECT dbms_xmlgen.convert(x.description.getClobVal(), 1) as description
FROM test_xml t
   , XMLTable(
       '/*/record'
       passing t.xml_data
       columns
         description xmltype path 'description/text()'
     ) x
;

Hi Friends,
My requirement is :
PO in IS retail system--(IDOC ORDERS)--Sales Order processing-->Sales order in AFS system
where AFS is apparel footwear solution used in retail industries.
Now I have created PO in IS-retail system , and IDOC is successfully generated .
After this I am checking this IDOC in AFS system thru tcode BD87 for processing but getting error mesage in next screen when I am executing BD87 after putting the IDOC number.
The operation cannot be carried out with this node type
Message no. B1891

SQL 2012 AlwaysOn AG with 3 Nodes

First, what would be the best option of quorum/quorum witness for my SQL 2012 AlwaysOn group?
I have setup the following:
SQL 2012 AlwaysOn with 3 nodes.
1 primary
2 secondaries - one of them is read-only (for reporting and backup)
Dynamics CRM and Reporting DBs are running on them.
How can I achieve the highest avalability and DR with my SQL? Do I even need to create the quorum witness? What kind of Quorum (majority nod with network share?)
Second, Is it good idea to run the backup on that read-only node? If I setup the maintenance plan on this 3rd read-only mode with full and transactional backups, I should be able to restore without any issues?
Third, I have another DB (SharePoint) that needs to be moved over to this SQL AlwaysOn AG but wondering if I can restore it in the secondary node to utilize the unused resources. Is that possible or not recommended?

Are the replicas on the same network subnet? If they are, then, you already have a quorum with node majority (odd number of votes.) Since you are already paying for an additional license to run read-only workloads on your readable secondary, you can take
backups on this replica. Full database backups are in COPY_ONLY mode but you can take regular log backups which will truncate the log on the primary replica. In theory, you will be able to restore the backups taken from your readable secondary but you should
test (hence, why I mentioned "in theory.") I wouldn't move my SharePoint databases to this SQL Server Availability Group mainly because of the different requirements between the two - SharePoint and Dynamics CRM. MAXDOP =1, disabling index maintenance and
statistics updates on SharePoint databases, etc. are just a few of them. Besides, I doubt that the recovery objectives and service level agreements between those two applications are the same within your organization.

[FPGA] Loop rate very slow: Do FPGA I/O nodes in parallel loops block each other?

Hi,
I am using cRIO-9075. Mod1 is NI 9263, Mod2 is NI 9227, Mod3 is 9215.
Please see my VI attached or the given screenshot.
The FPGA code is based on the "NI CompactRIO Waveform Reference Library" (it's the lower loop).
The upper loop was added by me and is writing a waveform from blockmemory to the NI 9263 module (Mod 1).
The data sampled in the lower loop is running at 1 kHz. The control "AO Update Period" for the upper loop has a value of (for example) 10 (=uS).
The problem is, that this loop is running much much slower than it should. Once I disable the FPGA I/O node in the lower loop (as done in the attachments), it's running as fast as it should.
It seems to me, that the FPGA I/O nodes are blocking each other. I tried to figure it out by reading through serveral NI documents, but until now I have no idea how to solve that.
Can you give me some advices? Some general tipps about the VI?
Thanks!

Hi, thanks so far.
Originally the control was inside the loop. Then I tried if it makes a difference if it's outside.
Ok, i really seems to be that default value of "100000" for "AO Update Period".
Starting the VI directly woks like expected. Having "AO Update period" inside the loop makes it possible to control it as it's running.
But, please see the attachment. When starting the FPGA through RT and setting the appropiate value, it does not seem to work. The oscilloscope show's the same behavior like "AO Update Period" was 100000.
But when reading the value of "AO Update Period" afterwards (while the FPGA is running), it shows the expected value of "10".
Having changed the default value to 10 works so far, but I am not able to changed it (see attachment).
So the problem is: Why is "Read/Write control" not working here? Why is still the default value used?

Fpga i/o node error - input is not configured

I'm trying to run through the sbRIO eval kit tutorial, and am getting the following errors from HD44780 FPGA.lvlib:
The FPGA I/O In parameter on the FPGA I/O Node is wired to an input that is not configured. Select an I/O item from the control or constant. You also can configure the input by right-clicking the control or constant and selecting FPGA I/O Category from the shortcut menu.
I'm really at a loss since I'm just learning how to utilize FPGAs in LabVIEW (2011 SP1), and was getting similar errors on my own.
I'm using the "NI LCD Module Driver, 1.1.0.11" driver installed by the VI Package Manager.
Any help will be greatly appreciated.

Hey Scottso,
Right click the FPGA target in your project and select new-> FPGA I/O. You should see the mezzanine card in a tree structure. Expand it and all your IO shoudl be available underneath. Press the arrow to add the channel to your New FPGA I/O Listbox then press OK. It should then put the IO into your project to be used. You can then drag the I/O from your project and drop it on your block diagram. Another option is to click on the node you have shown and choose "Add New FPGA I/O" or if you already have the IO in your project you can click the node and choose "Select FPGA I/O"
