Initial condition in CD parametric time response (control design)

CD parametric time response calculates the output of system when a step input excites it, and the initial conditions are the initial values the parametric response uses. But there is a miscalculation in the taking into account of the initial conditions.

You need to give us more information about what you are trying to do, with which tool and what the problem you are experiencing. With this information you will probably find someone in this community that can help.

Shared Variables for Real-TIme Robot Control

I'm really stuck in my efforts to use LV real-time in my hardware control application. I have a 6-axis industrial robot arm that I must control programmatically from my PC. To do this I've developed a dynamic link library of functions for various robot control commands that I can call using Code Interface Nodes in LV (using 8.5). This has worked great, that is, until I tried to port parts of the application to a real-time controller. As it turns out, because the robot control dll is linked with and relies so heavily upon several Windows libraries, it is not compatible with use on a RT target, as verified by the the "DLL Checker" application I downloaded from the NI site. When the robot is not actually executing movements, I am constantly reading/writing analog and digital I/O from various sensors, etc.....
This seemed to suggest that I should simply segregate my robot commands from the I/O activities, using my host PC for the former, and my deterministic RT loop on the target machine for the latter. I set up a Robot Controller Server (RCS) vi running on my host PC that is continuously looking for (in a timed loop) a flag (a boolean) to initiate a robot movement command. Because several parameters are used to specify the robot movement, I created a custom control cluster (which includes the boolean variable) that I then used to make a Network Shared Variable that can be updated by either the RT target or the host PC running the RCS. I chose NOT to use buffering, and FIFO is not available with shared variables based on custom controls.
Here's sequence of events I'd like to accomplish:
1) on my host PC I deploy the RCS, which continuously pools a boolean variable in the control cluster that would indicate the robot should move. The shared variable cluster is initialized in the RBS and the timed loop begins.
2) I deploy the RT vi, which should set the boolean flag in the control cluster, then update the shared variable cluster.
3) an instance of the control cluster node in the RCS should update, thereby initiating a sequence of events in a case structure. (this happens on some occassions, but very few)
4) robot movement commands are executed, after which the boolean in the control cluster is set back to its original value.
5) the RT vi (which is polling in a loop) should see this latest change in the boolean as a loop stop condition and continue with the RT vi execution.
With the robot controller running in a timed loop, it occassionally "sees" and responds to a change of value in members of the shared variable cluster, but most times it does not. Furthermore, when the robot controller vi tries to trigger that the movement has completed by changing a boolean in the control cluster, the RT vi never sees it and does not respond.
1) Bad or inappropriate use of network shared variables?
2) a racing issue?
3) slow network?
4) should I buffer the control cluster?
5) a limitation of a custom control?
6) too many readers/writers?
7) should I change some control cluster nodes to relative, rather than absolute?
8) why can't I "compile" my RT vi into an executable?
Any help would be greatly appreciated. Unfortunately, I'm writing this from home and cannot attach vi files or pictures, but would be happy to do so at work tomorrow. I'm counting on the collective genius in the universe of LV users and veterans to save my bacon.....

Hi David,
I'm curious why you decided to build a CIN instead of developing the code in
LabVIEW. Is there some functionality that that LabVIEW couldn't
provide? Can you provide some more information about the LabVIEW
Real-Time target you're using? What type of IO are you using?
It is impossible to get LabVIEW Real-Time performance on a desktop PC running
an OS other than LabVIEW Real-Time. Even running a timed loop in LabVIEW
for Windows won't guarantee a jitter free application. Also, no TCP based
network communication can be deterministic. This means Network Shared
Variables are also not deterministic (they use a TCP for data transport) and I
advise against using them as a means to send time critical control data between
a Windows host and a LabVIEW Real-Time application.
In general, I would architect most LabVIEW-based control applications as
follows:
- Write all control logic and IO operations in LabVIEW Real-Time. The
LabVIEW Real-Time application would accept set points and/or commands from the
'host' (desktop PC). The Real-Time controller should be capable of
running independently or automatically shutting down safely if communication to
the PC is lost.
- Write a front-end user interface in LabVIEW that runs on the desktop
PC. Use Shared Variables with the RT-FIFO option enabled to send new set
points and/or commands to the LabVIEW Real-Time target.
Shared variable buffering and RT-FIFOs can be a little confusing. Granted
not all control applications are the same, but I generally recommend against
using buffering in control applications and in LabVIEW Real-Time applications
recommend using the RT-FIFO option. Here's why: Imagine you have a
Real-Time application with two timed loops. Time-loop 'A' calculates the
time critical control parameters that get written to hardware output in
timed-loop 'B'. Loop 'A' writes the outputs to a RT-FIFO enabled variable
with a RT-FIFO length of 50. Loop 'B' reads the outputs from the shared
variable, but for some reason, if loop 'B' gets behind then the shared variable
RT-FIFO will now contain several extra elements. Unless loop 'b' runs
extra fast to empty the RT-FIFO, loop 'B' will now start outputting values that
it should have output on previous cycles. The actual desired behavior is
that loop 'B' should output the most recent control settings, which means you
should turn off buffering and set the RT-FIFO length to 1.
There is also a clear distinction between buffering and the RT-FIFO
option. The RT-FIFO option is used to add a non-blocking layer between
network communication and time-critical code in LabVIEW Real-Time
applications. It also provides a safe mechanism to share data between two
loops running in a Real-Time application without introducing unnecessary
jitter. Network buffering is a feature that allows a client to receive
data change updates from the server even if the client is reading the variable
slower than the server is writing to it. In the example I presented above
you don't need to enable networking because the shared variable is used
entirely within the Real-Time application. However, it would be
appropriate to send control set points from a Windows PC to the Real-Time
application using network published shared variables with the RT-FIFO option
enabled. If it is critical that the Real-Time application executed all
commands in the sequence they were sent then you could enable an appropriate
buffer. If the control application only needs the latest set point
setting from the Windows host then you can safely disable network buffering
(but you should still enable the RT-FIFO option with a length of 1 element.)
Network buffering is especially good if the writer is 'bursty' and the reading
rate is relatively constant. In the robot application I can imagine buffering
would be useful if you wanted to send a sequence of timed movements to the
Real-Time controller using a cluster of timestamp and set point. In this
case, you may write the sequence values to the variable very quickly, but the
Real-Time controller would read the set points out as it proceeded through the movements.
The following document presents a good overview of shared variable
options: http://zone.ni.com/devzone/cda/tut/p/id/4679

Multiple conditions in a filter of Bursting control file

Hi All,
I am trying to use multiple conditions in a filter of Bursting control file and it throws me an error.
Can you please correct me on this.

Conditions for triggering actions - times in SLA

Dear CRM experts,
I'm configuring actions in SAP CRM 2007 - Service Scenario: in particular, I'm trying to configure actions for triggering of e-mails when SLA deadlines are reached.
Let's assume that the following are the dates in my service ticket:
Opening of the ticket --> 10/05/09 - 10:15 A.M.
First level of escalation --> 10/05/09 - 02:15 P.M.
To Do By --> 10/05/09 - 06:15 P.M.
When I write the Starting Condition for the action, I can only compare the Date Types (Opening of the ticket , First level of escalation, To Do By ) with the Local Date of the System...
The problem is that the condition considers only the DATE(10/05/09), but not the TIME!!
But in our scenarios, the time is a critical parameter!
Any idea on how to solve my problem?
Thanks in advance,
regards,
Andrea Ricci

Dear Andrea,
I have similar requirement,Where as i have maintained the first respone as date type and in duration i have maintained 15 Min.
Where as in action condition I have maintained Fisrt response<current date. Notification receipt as Todays date and time.
Please guid me in details.
Regards
Ashwin

Page Transition - Initial Conditions

Hi all,
I have prepared an interactive widget for an iBooks project of mine. I am having a problem when initiating a go to page transition.
Page 1 works fine
Page 2 works fine when "Go to Page is selected from Page1"
Page 1 works fine when "Go to Page is selected from Page2"
However Page 2 does not start-up the same way it did on the first run.
Its appears Page 2 does not start-up with the same initial "conditions".
Is there something I am missing at the point of transition? or am I having a problem with Page Did Load?
Can anyone help?
Best,
T

See the documentation:
http://help.apple.com/iadproducer/mac/5.0/#/iade80653a8
The key part:
Often used before the user has navigated to a page for the first time; when actions need to occur once per page.
The net result is that navigating back to page 2 will restore the page to the state it was in when last navigated away. If you want something to happen on every appearance, use Page Did Appear.
Does that help?

DSEE 7 error code 12 - Sort Response Control for server side sort

I am using Sun DSEE 7, My application works fine for small data set (e.g. 1000) and gives me correct sorted result, but same code fails for large data set (e.g. 656000). I find that for large data set, I am getting the error "*javax.naming.OperationNotSupportedException: [LDAP: error code 12 - Sort Response Control];*". I have changed the look-throught-limit, size-limit and time-limit values to unlimited using dsconf utility. I changed db cache size, entry cache size to appropriate values and also i increased all-id-threshold, all-ids-threshold-eq, all-ids-threshold-pres to the max possible value (2147483646) for one index attribute which i am using in my query but still exception is coming. If i change my client code (Java code using JNDI) to use Context.NONCRITICAL for SortControl, the sorted result is coming fine for small data set (access log shows query as indexed) but result is not sorted for large dataset and also i see the query is now unindexed. I am using only one attribute for sorting. Please help me out what configuration i am missing here.

Exactly. There is no reason to have the LDAP server sort the
results during the retrieval.
Query of Query can be used such as:
<cfldap name="ldapResults" .....> 
<cfquery dbtype="query" name="sortedResults">
SELECT
FROM
ldapResults
ORDER BY
sprintcompany
,sprintpocrole
,sn
</cfquery>
Then, use the "sortedResults" query for the rest of your
processing.

How to trigger Condition Access sequence multiple times for one line item?

Hi,
We have a situation that, User will enter a Promo code (custom Field) in Sales order Header Additional data B tab to apply discount for line items.
Logic goes like this:
1. For each Promo code .. there may be multiple sale deals (Max 3 at this point).
2. For each line item (refering to tkomp table) we have to apply the sale deals (found above) the Condition access sequence will pick the right sale deal to apply the line item.
3.we have enhanced the tkomp structure to hold the sale deal.
Challenge:
As we have the standard logic to trigger the condition access sequence once for each line item, how we can apply 3 sale deals for single line item. Is there any logic or way to trigger the condition access sequence multiple times for single line item with diffrent sale deals. ~ There may be one valid sale deal for one line.
Functional team maintained diffrent access tables in the access sequence!!!
Fnds, please help me to get some clue
Thanks,
Sunil Y

Hi Eduardo , Thanks for the response.
I am trying to explain again, this is the requirment given by the functional guys.
we have Promo code in Hearder Addtional data B tab --> Have to retrieve Sale Deals -->
At this point of time we may have at max 3 Sale Deals. we don't know which sale deal is vallied for which item we have in TKOMP. We have enhanced the TKOMP structure to hold one sale deal only (ZZPROMO).
We have enhanced USEREXIT_PRICING_PREPARE_TKOMP in RV60AFZZ to populate the value in TKOMP. Then it will go for diffrent access sequence to find the proper condition.
Our challenge is that, for each line item we have 3 sale deals, we don't know which one is valid for which line. but we have to apply the vallied sale Deal to the line items. Line item 10 may have Sale Deal 2 , item 20 may have Sale Deal3 and 30 may have sale deal 1.
We may have solution, by fixing some thing in the code or through config. But i am confused that is it a valid requirment?
Please help me ...
Thanks,
Sunil Y

Initial condition as programmable input

I am simulating a small photovoltaic panel (island power plant). The model is running in LV and the circuit parameters are computing in subVI with Multisim model.
The model works very good, but for right function is necessary set the voltage of the PV diode as initial condition. Its OK, but for better function I need to control initial condition as input from VI.
My question is: Is possible to control initial condition as input from VI?
Thank you for your help.

Hi Slezinger and welcome to NI forums!
I'm afraid this functionality is not available for co-simulation, so the only way I believe you can implement this is to have a dedicated input/circuitry to set your parameters at t0.

Microsoft Date and Time Picker Control 6.0 (SP6) errors

One of our functioning VBA projects in Outlook 2010, running under Windows 7 Professional (64-bit), unexpectedly stopped functioning a few months ago. When running the VBA macro we started receiving the compile error message:
"Object library invalid or contains references to object definitions that could not be found"
PROBLEM FORM CONTROL: The message was extremely frustrating because it gave no detailed indication of the source of the problem. With a little research, however, we found that the
Microsoft Date and Time Picker Control 6.0 (SP6), on a userform accessed by the macro, was generating the error. A number of older articles, such as the one included below, indicated that we needed
to re-register the MSCOMCT2.OCX form control, which we did successfully (as did the original author in his question link below). Unfortunately, as the original author found, simply re-registering the form control did not resolve the problem.
UNRESOLVED QUESTIONS:
1. Does anyone know why this functioning control would unexpectedly cease to function?
2. Can anyone help us restore the functionality of the 'Microsoft Date and Time Picker Control 6.0 (SP6)'?
3. How come the form control is listed in the object library, is available in the 'Additional Controls' dialog, and can be inserted into a form, without any indication that it is broken?
SUPPORT ENGINEER RUN-AROUND: Another frustration is that a responding support engineer, in the prior article, keeps referring the author back to this forum, yet the question is apparently never answered back here in
the TechNet forum (which ironically refers us back to the original article in the other forum - a game of musical chairs!).
We suspect that the solution to this problem may be similar to resolving this issue for other similar form controls in other Office 2010 application, not just Outlook. After several years, and a myriad questions on the internet regarding
this exact subject, is there someone who can definitively resolve this issue with this control?
Thank you for any help.

Hi,
Would you like to tell me your Excel version number (Go to Account>About Excel). I tested in my version :15.0.4569.1504 and the Date and Time Picker Control 6.0 still could be used.
Then,>> My PC is 64 bit. I believe my version of Office is also 64 bit.<< Office 2013 32 bit also could be installed in 64bit operation system. We could check it with Account>About Excel.
Next, as you said >>After I exited 'Design Mode,' it started working again. I tested it, along with my 'Clear Form' button multiple times. It seemed to be working fine. I closed the document and reopened it. Enabled Macros.
When I tried to use it after reopen, it doesn't work again.<<
I recommend we recreate a new blank Excel file and insert the Date and Time Picker Control 6.0 to test.
If it still does not work well, please try to reinstall and re-registry it. Follow the link:

If it works well, I suppose this issue is related to macros. I recommend you post the question to MSDN forum to debug them:

How to limit data range in a Line chart with Time Refresh Control

Hi All,
I have a Line chart with Time Refresh Control and I would like to make some constraints to this navigation.
For example, I would like to limit the user to navigate in a data range of 8 hours.
Is this posible?
Thanks in advance

Hi Pedro,
as far as I know, this is not possible using the time controls on an iChart. However, you may have some success by using your own time controls which call JavaScript methods exposed by the applet.
For example, you could begin by hiding the time and calendar buttons on an iChart, and creating some buttons of your own. For instance, to set the start date of a query (and thus the start date of the iChart using the query), you can use the following:
document.getElementById("appletID").getQueryObject().setStartDate(<date string>);
Using code like the above (look into the xMII script assistant and documentation), you should be able to build time controls which satisfy your requirements. The exact format of <date string> in the sample above will depend on the date format defined in the query template this script calls.
Hope this helps,
Sascha

Condition Types appearing two times in a Purchase Order

Hi,
The condition types are same in supplementary schema (for Info Record) and Purchase Order Calculation Schema. When I put some value against a condition type under conditions in Info Record then that condition type appears 2 times in the purchase order. It seems the condition type appears 1st time (with value from Info Record) because it is picked from Info Record and 2nd time (with no value) from the Purchase Order Calculation Schema.
The requirement is condition type should appear only single time in PO (by default) with or without value in spite of having info record. In case some value is maintained in Info Record then the condition type should appear with value but in a single line in PO which can be edited if required. There should not be second line of same condition type by default in PO.
Can anyone provide some idea to resolve this?
Thanks in advance

There is only 1 condition line (apart from PB00), which comes 2 times in PO by default, in MEK2 and also one condition line (one line was deleted and then saved) in last PO (from the Info Record). But the condition type still comes 2 times while creating a new PO.
Please provide some more answer to resolve this issue.
Thanks in advance

VERY slow initial full back up using Time Machine.

I had a problem with my Time Capsule and had to erase the drive. Now it's running the initial full back up - but, in 21 hours and 48 minutes it's only done 93.11 GB of the total 241.05 GB. Is this very slow progress normal? I'm sure it didn't take this long when I first ran the initial back up when the Time Capsule was new.

Doesn't sound like the same problem. You seem to have a problem with your Mac, not necessarily backing-up.
I decided to use time machine to back everything up. I formated the WD to the same as my mac and ran time machine but has only completed 9.81gb out of 485.68gb and not moved for 6 hours.
Cancel the backup (if it won't cancel after several minutes, see #D6 in Time Machine - Troubleshooting).
Then verify your internal HD, per #6 in Using Disk Utility.
If that reports that it "seems to be ok," you may have a hardware problem. Try running this: Intel-based Macs: Using Apple Hardware Test. Run the Extended tests (that may take an hour or so, depending on how much RAM you have). Write down any error code(s) it shows.
Apart from doing a back when i first purchased the imac.
You haven't done a backup in 2 1/2 years? Eeek!

Problem in Multisim with transient analysis and initial conditions

Hello everyone,
I have a problem in multisim with transient analysis and initial conditions.
If I do transient analysis with automatically determined initial conditions the circuits works.
If I do transient analysis with user-defined initial conditions the circuits works in cases.
--Working with user-defined---
*## Multisim Component V2 ##*
vV2 3 0 pwl(0 0 0.001 0 {0.001+1e-008} 3 {0.001+1e-008+1} 3)
*## Multisim Component R1 ##*
rR1 3 0 10000 vresR1
.model vresR1 r( )
--Working with user-defined----------
*## Multisim Component V2 ##*
vV2 1 0 pwl(0 0 0.001 0 {0.001+1e-008} 3 {0.001+1e-008+1} 3)
*## Multisim Component U1 ##*
xU1 1 0 MEMRISTOR__MEMS__1__1
--Not Working with user-defined-------
*## Multisim Component V2 ##*
vV2 3 0 pwl(0 0 0.001 0 {0.001+1e-008} 3 {0.001+1e-008+1} -3)
*## Multisim Component R1 ##*
rR1 3 1 10000 vresR1
.model vresR1 r( )
*## Multisim Component U1 ##*
xU1 1 0 MEMRISTOR__MEMS__1__1
The costum component includes something like that:
.subckt MEMRISTOR__MEMS__1__1 plus minus PARAMS:
*Parameters values
+rmin=100 rmax=390 rinit=390 alpha=1E3 beta=0 gamma=0.1 VtR=1.5 VtL=-1.5 yo=0.0001
+m=82 fo=310 Lo=5
blah blah ...
.ends Memristor
Namely, if I combine the resistor and my custom component in one circuit, transient analysis with user defined initial conditions gives an error (timestep too small).

Hi Nik,
If possible, please post the Multisim file. This way, I can get access to all your settings.

Microsoft Date and Time Picker Control 6.0 - Need help!

I am working on a form in Office 365 Excel 2013 that uses the Microsoft Date and Time Picker Control 6.0. When I set the form up last week, this Active X control was working perfectly. The weekend goes by...and now it's not working at all?
My PC is 64 bit. I believe my version of Office is also 64 bit. When I researched this issue online, I found lots of people who indicated that this control was missing in their development kit. It was and has always been available in mine
(i.e. I didn't have to load an MSCOMCT2 file). Further, this control WAS WORKING when I created it last week. Now it is not, even though no changes have been made to it. I can place the control on the sheet and even set properties for it.
But once I click out of Design Mode, it is not functioning. It doesn't open or respond to any clicks on it.
Can anyone help me identify a reason why it may have suddenly stopped working? I don't think it is macro-related because I have a 'Clear Form' button on the same page and it works just fine.
UPDATE: I've noticed something else peculiar but relevant. My office 365 just did some updates. When updates were completed, it auto-reopened my file. I noticed that the Date/Time Picker button looked funny (really pixelated).
So I hit 'Design Mode' and resized it. After I exited 'Design Mode,' it started working again. I tested it, along with my 'Clear Form' button multiple times. It seemed to be working fine. I closed the document and reopened it.
Enabled Macros. When I tried to use it after reopen, it doesn't work again. Won't respond to ANY attempts to click on it. I can click on 'Design Mode' and it sees the control, edits properties, etc. But when you click out of 'Design Mode,'
it's a dead button again. I also went to someone else's desk to test this form. Same problem. Date/Time picker button doesn't work, even after enabling macros. The Clear Form Button has no problems though.
Thanks!

Can't show 7PM with Time Stamp Control

Maybe it's just me, but I can't seem to get any time stamp controls to accept 7PM as an entry.
....this is kind of a problem for the data entry I'm supposed to be doing this weekend.
Any workaround?
Patrick Allen

Thanks for the reply Guenter.
It's very strange. Even after shutting down LabVIEW and starting with an entirely new VI, the time stamp control always displays 00:00:00 when I try to enter 7PM.
I've tried changing the defaults to just about everything. But it's always the same behavior.
For my work around I decided to just use Excel for all my raw data entry. I'll write program to stuff it all in the database later.
*edit*
I just downloaded the attachment on your reply.....and it worked just fine.
I'm uploading the entire .vi now. This is bizare.
