9144 with custom FPGA and SGL EtherCAT User-defined Variables?

Hi,
I currently have a small instrument driver (rs485) running on a 9144 chassis. The output values are communicated to the EtherCAT Master using FXP numbers. I would like to switch these FXP to SGL since I upgraded to LV 2012 SP1 with FPGA now supporting SGL numbers.
Is this possible? I tried several times to create the SGL User-defined Variables in the project, but the date type is grayed out.
Greetings from Munich,
Götz
Solved!
Go to Solution.

Unfortunately, SGL is not a supported data type for communication to/from a 9144. The available data types for user-defined I/O variables are:
* Fixed Point
* Signed Integers(Int8, Int16, Int32, Int64)
* Unsigned Integers (UInt8, UInt16, UInt32, UInt64)
* U32 Bit Field
* Boolean

Applying User Defined Variables across project

Hello,
I'm working with the User Defined Variables feature and can't
seem to figure out how to apply a variable/value across all topics.
I may have misunderstood the definition of what this is supposed to
do, so it may be user error. It is my understanding that if you
have information that use repeatedly, for instance if I refer to a
product name in numerous topics and the product name changes, I can
set up a user defined variable and set this to update all the
occurrences. I can change it going in each topic and each sentence
where the occurence is by right-clicking the word and selecting
Insert User Defined Variable. Any ideas as to what I can do to make
a global update. Also, I'm reading the help, but still seem to be
missing something.
Thanks,
Michele

Thank you, Peter! This article is very informative and much
more clear (to me) than what I read in the RoboHelp help manual. I
understand now that this feature is used when you are creating
topics in a project and anticipating what may change--in which case
you insert the variable as you need it, then if it changes in the
future you can update it easily. I was looking at it as more of a
global search and replace to update information that already
exists. I think it will come in handy with our documentation
projects.
Thanks again. :-)

Custom Quiz: How to update and report user-defined variable?

Hello,
I am a novice Captivate 5.5 user. Thanks to Lilibiri's blog and articles, I have managed to built a custom quiz (all with user-defined variables and advanced actions).
The quiz is composed of 2 questions with 4 possible answers each. Each of the 4 answers have a different score attached to it (i.e. answer a = 4 points; answer b = 3 points; answer c = 2 points; answer d = 1 point). I have inlcuded a "Feedback Slide" that may appear after each question. For example, if a person chooses score d, they will get sent to a Feedback slide that basically says they are wrong. There is a "back" button on the "Feedback" slide that can take them back to the the prior question sllide and they can change and re-submit their answer. After they have answered both question slides, they continue to a "Results" slide. Upon entry to the "Results" slide, using "advanced actions" my user-defined variable adds up all of the scores to get a total. Based on this total, one of three possible text captions boxes appear, depending on their total. And....here are my questions (I have checked and re-checked the Forum and blogs for answers - and I am so sorry if I missed them!!)
1) I have defined a variable that totals the points that the person received on the quiz. I would like this variable displayed on the Results slide. It can get it to appear in a Text Caption Box. BUT if a person changes a score and re-submits the score before entering the "Results" slide, the total score reflects EVERY score that the person has chosen (the scores that they originally chose and then changed are still included in the total).
2) I want the total score a person gets on the quiz reported to the instructor. I don't know if a user-defined variable can be reported and how to go about doing this. We will be running our quizzes on an LMS (though we haven't chosen one yet). I tried using a system variable (cpQuizInfoPointsscored), but I believe (after reading discussions on Forum), it will not work in my quiz if my scores are adjusted/changed.
3) another question - would you like me to put this in a separate discussion? I certainly can!! There is a "Back" button on the "Results" page. I have tried using "advanced actions" and "on success: move to last slide visited" but neither option will allow the user to move to the last slide visited. Ideally, I would liek a person to be able to go back through the quiz, look at their answers and adjust them.
Thanks in advance for your help! I have learned SO much in the last few weeks from all of you!

Hello and welcome to the forum,
That is a lot of questions, thanks for reading my blog. The most difficult part is indeed the reporting in case, you did see perhaps that I have not yet published the blog post about reporting questions with partial scores, third part of my reporting sequence. Have two possibilities that I'm exploring: either with Javascript, or with the brandnew Master Widget that Rod is pointing to. Watch out for the blog post(s), but need some more time. So no real answer to your second question for the moment, because you cannot control the quizzing system variables with advanced actions.
About your first question: you will have to so sort of 'reset' when re-entering the question slide, so that the total score stored in the user variable is decremented with the score attributed to the user in his previous answer. This means that you have to store this previous score in another user variable. Hope this make sense?
I do not get the last question totally. Are you using the default Score slide? You have to allow Backwards movement in the Quiz Preferences, but for default Question slides this will not allow the user to change his answer. I thought you were using custom question slides? Do not use the default score slide in that case, but create your own score slide, so that you can add buttons and actions to your wish. Perhaps I misunderstand your question, and it would be better to explain more, eventually in another thread if it is about the default score slide, question slides.

Find and Replace with User Defined Variable

I am in the process of converting some legacy help content to RoboHelp HTML 9 in order to give it some more features and customization for our clients. I have been taking advantage of User Defined Variables in order to customize the content. Up to this point I have been manually going through each topic and replacing each instance of a word ("statements" for example) with a user defined variable saying the same thing but with the possibility of being changed later should the customer want to. Though we only have about 200 topics, this is still relatively time-consuming and I would like to automate this as much as possible.
Is there any way to find and replace content with a User Defined Variable?

Hi there
If you open the Script Explorer pod I believe one of the sample scripts is a "UDV Converter" script. Perhaps you could give that a try.
Cheers... Rick

10.9.1 used terminal with rm-rf and deleted my user data. Can I get back the deleted data? Help.

10.9.1 used terminal with rm-rf and deleted my user data. Can I get back the deleted data? Help. I really just need mail file and desktop files recovered.

If data were on the SSD drive with TRIM - practically no chance. If HDD - use DIY recovery software such as DiskDrill or DataResue.
As quickly as possible turn off the drive where deleted data.
Use an external HDD with installed OSX for data recovery.

How to print jTable with custom header and footer....

Hello all,
I'm trying to print a jTable with custom header and footer.But
jTable1.print(PrintMode,headerFormat,footerFormat,showPrintDialog,attr,interactive)
does not allow multi line header and footer. I read in a chat that we can make custom header and footer and wrap the printable with that of the jTable. How can we do that..
Here's the instruction on the chat...
Shannon Hickey: While the default Header and Footer support in the JTable printing won't do exactly what you're looking for, there is a straight-forward approach. You can turn off the default header/footer and then wrap JTable's printable inside another Printable. This wrapper printable would then render your custom data, and then adjust the size given to the wrapped printable
But how can i wrap the jTable's Printable with the custom header and footer.
Thanks in advance,

I also once hoped for an easy way to modify a table's header and footer, but found no way.
Yet it is possible.

Flash Wrapper and Accessing user-defined variables

I am working on creating a Flash AS3 wrapper to combine several cpativate files. I am able to retrieve system variables, however I am not able to retrieve user-defined variables. I have a user defined variable in my Captivate called passedScore, in my Flash script I have the following...
var mcLesson1:MovieClip;
btnHit.addEventListener(MouseEvent.CLICK, test);
var vLoader:Loader = new Loader();
vLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, swfLoaded);
vLoader.load(new URLRequest("untitled1.swf"));
function swfLoaded(e:Event):void {
mcLesson1 = MovieClip(vLoader.contentLoaderInfo.content);
vLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE, swfLoaded);
addChild(mcLesson1);
function test(event:MouseEvent):void
feedback1.text = mcLesson1.cpInfoCourseName;
feedback2.text = mcLesson1.m_VarHandle.passedScore;
feedback1 correctly shows the course name, however, for feedback2 it errors saying a term is undefined (refering to m_VarHandle)

try using mcLesson1.cpEIGetValue('m_VarHandle.passedScore');

User defined variables transfer data

Hello
I am using the etherCAT 9144 chassis and this hardware supports only target scoped FIFO. After a search, I realized that the only way to transfer data from FPGA to Host is by using User defined variables. But these variables do not support FIFO concept. So, which is the best practice to transfer data after measurements ( e.x 10Hz measurement of 15 values ) to host VI ?
Thanks
Solved!
Go to Solution.

As mentioned, the 9144 only supports scan engine.
As for what you should do, that really depends on the whole application. For example, what is the master? Are there other systems involved here? Etc. This is a good read in general, although it might not help right this second: http://www.ni.com/white-paper/14151/en/
From a high level you should decide what you need. If you need deterministic, low latency communication over longer distances from an RT controller, the 9144 is probably the right choice. If you need low-latency+streaming over short distances from an RT controller, you should look into the MXI RIO chassis. If you primarily need non-deterministic low speed (10 hz) data mixed with low-throughput streaming over long distances from a windows or RT host, then the ethernet rio expansion (9146,7,8,9) is probably the right choice. If you need high speed streaming with low latency control over long distances from a windows or RT host, you need a full cRIO controller. Based on what you've posted so far, its uncertain what is the right fit.
Lets say you're stuck with the 9144 for now. Given that you can easily hit 1 kHz scan cycles, it should be perfectly achievable to "stream" data at 10 Hz. If you run scan engine at 1 kHz then you're oversampling by 100x. Where it gets tricky is that sync requirement. By default the I/O acquisition is synchronized to the scan clock (and you can see when the scan clock is set through an FPGA I/O node). However, you can take full control of a module in the FPGA and read the I/O at any time you please. That is, you can set it up so when DIO0 goes high you immediately sample all 15 AI values. You can then transfer those latched AI values to the host using user defined variables.

Using user defined variables in SAP BPC 7.0 NW

Hi,
I am using BPC 7.0 SP2 NW version. I want to do some calculatioins and/or comparision in the script logic by using user defined variables.
For Ex: I want to assign the property TIMEID of TIME dimension to a variable and then use this variable in my IIF statement.
I have tried a lot but not getting any solution.
Can anyone guide me in how to use user defined variables in Script Logic.
Your valuable reply is appreciated.
Thanks & Regards
Manoj Damle

Hi,
Thanks for the valuable reply.
But i want to define variables in the Script Logic and not in the Data Manager.
The scenario is like this:
I want to check the value of the DUMMYACC1 member of GL_ACCOUNT dimension with a constant and depending on the condition i want to update a user defined variable. This variable will further be used in the *SELECTCASE statement for decision making.
The Code is as follows:
*XDIM_MEMBERSET COMP_CODE = COMP_CODE_1
*XDIM_MEMBERSET BUS_AREA = BUS_AREA_1
*XDIM_MEMBERSET VERSION = VERSION_1
*XDIM_MEMBERSET CURRENCY = AUD
*XDIM_MEMBERSET DATASRC = DATASOURCE_1
*XDIM_MEMBERSET GL_ACCOUNT = SALESREVENUE,PRICE,QUANTITY,DUMMYACC1
*XDIM_MEMBERSET TIME=2009.MAY,2009.JUN
*XDIM_MEMBERSET CUSTOMERCATEGORY = CUSTOMER_CAT_1
*XDIM_MEMBERSET PROFIT_CTR = PROFIT_CTR_1
*XDIM_MEMBERSET SEGMENT = SEGMENT1
*XDIM_MEMBERSET MEASURES = PERIODIC
*FUNCTION PRO(%VAR1%,%VAR2%)
    [%VAR1%].CURRENTMEMBER.PROPERTIES("%VAR2%")
*ENDFUNCTION
*FOR %GL_ACC% = DUMMYACC1
    *FOR %CV_TIM% = 2009.MAY,2009.JUN
        #CUR_MTH = IIF(([GL_ACCOUNT].[%GL_ACC%],[TIME][%CV_TIM%]) = 1.,1,NULL)
    *NEXT
*NEXT
*SELECTCASE #CUR_MTH
*CASE 1
    #CURRENTMTH = PRO(TIME,TIMEID)
*ENDSELECT
The errors which system gives is:
1. Duplicate formula found
2. Invalid MDX statement
3. #CUR_MTH & #CURRENTMTH is not a valid member
Please give your valuable suggestion.
Thanks and Regards

Sequence Quiz Using User Defined Variables - Can See Underlying Variable Name On Move

I have just tested using 1 slide to capture several user defined variables and the next slide to insert those variables as options in a sequence quiz slide.
This works but as soon as I grab an object to begin sequencing them the underlying variable name shows up alongside the variable content.
Am wondering if I am attempting something that shouldn't be possible in Captivate and / or if there is a fix?
Thanks

Sure, I'm using Captivate 8. On a test project I've created:
a slide with 2 text entry boxes, their contents are stored in variables
another slide with a sequence question (using the native captivate question slide)
The labels on the 2 sliders on the question slide use the variables from the previous slide.
This works, so if the variables are as follows:
$$data_sequence1$$ - "blah blah blah"
$$data_sequence2$$ - "blah"
The labels on the sliders on the sequence question will be "blah blah blah" and "blah". as intended.
The issue is when I click one of the sliders to drag it to sequence the variable name will flash up on screen. So if I touch the slider with the label "blah blah blah" $$data_sequence1$$ will flash up on screen.
I have other slides on there but these are the two related to this question. I haven't fully published the project I've previewed it.

User-defined variables in Search Results pane

I am working with user-defined variables for WebHelp output.
I have successfully added the variables to the topic, the displayed
topic title, the TOC, and the Index entries. The problems lies in
getting the search output to display the specified variable text.
For example, the base topic title is "Introduction to XX". I
use a variable to change the XX to YY throughout the project;
however, when I generate the output and then Search for YY, the
search results pane displays "Introduction to XX" even though the
displayed topic is titled, correctly, "Introduction to YY". I am
assuming, because the topic title is not adhering to the variables,
that the search results displays the metadata <title>.
What should I do so the search results title syncs with the
other data?
Carol

Welcome to the forum.
There have been two posts about this recently so do a search
for more information.
Basically the search results show the Topic Title as defined
in Topic Properties. Your variable is in the Topic Heading at the
top of the page. Not the same thing.
I suggest you request a feature change.

Where has the user defined variable pod gone?

Last week I used the User Defined Variable pod to define some
user defined variables in a project.
Today I click View > Pods > User Defined Variables and
nothing appears! Furthermore, on the Insert menu, the User Defined
Variable option is greyed-out.
Has anyone experienced this before? What is the solution?
Regards
Ian Saunders

I'm not the great and powerful Peter, but hopefully youl find this helpful.
Right-click the menu and choose Customize... Then from the General tab, ensure the Menu Bar is selected and click the Reset... button.
Dismiss the dialog and see if things are better.
If it helps, I've spent time with Peter on a few occasions. Perhaps that helps my credibility?
