How to convert a dynamic data type to array of strings

I want to perform a serial communication between two
computers that I´ll call them A and B. The computer A (transmitter)
will send a signal (sinusoidal) to computer B (receiver). I´m using a
VISA Serial Communications Set (VISA Configure Serial Port.vi, VISA
Write.vi, VISA Read.vi and VISA Close.vi). VISA Write accepts
only string data type and VISA Read reads only string data type, but
the signal that I generated (on transmitter) is dynamic data and I need
to perform this conversion to run my program sucessfully. How can I
perform this conversion?!

Hi Rafael,
You can configure the From DDT Express VI to convert your dynamic data to any number of different types. By default, the Express VI will convert to a 1D array of numerics...however, you can configure it (either when you first drop it, or by double-clicking it) to convert to a 2D array of numerics...additionally, you can configure it to convert based on channel data being in columns or rows. I have attached another screenshot that shows converting the dynamic data into a 2D numeric array.
I hope this helps.

How do you save dynamic data type, from the DAQ assistant, for use in Excel or matlab?

Currently, I have the following basic VI setup to save Data from my PCI6221 Data Aquisition Card. The problem I'm having is I keep getting the last iteration of the while loop in the measurement file and that's pretty much it. When I try to index the data leaving the loop it gives me a 2D array of Data which cannot be input into the "Write to Measurement File" VI. How would I save this to a useful Data/time step format? I was wondering of a way to continuously collect the Data and then save it in a large measurement file that I would manipulate in Matlab/excel? Am I using the wrong type of loop for this application? I also noticed my Dynamic Data array consists of data, time, timestep and then a vector of the data taken. Is it possible to just get a vector of the time change per sample alongside the data? Sorry for the barrage of questions but any help would be greatly appreciated, and thanks in advance!

There is a VI in the Express > Signal Manipulation palette called "From DDT" that lets you convert from the Dynamic Data Type to other data types that are more compatible with operations like File I/O....for instance, you could convert your DDT into a 2D array and use the Write To Spreadsheet File.vi. Just a thought...

How to convert an xml data(clob) in database to string format in bpel??

Now I am learning SOA ,I have one scenario which I store the each record in xml format in database from file adapter ,extract the xml data and store the data in another table ...Give me any suggestions which I slove these issue .
Thanks in advance.

Hi
You can try the below xpath function to convert the xml into string - orcl:get-content-as-string(/xsdLocal:SAPOrderRequest)
To convert the string back to XML - ora:parseEscapedXML(bpws:getVariableData('stringpayloadVar'))

How to add dynamic data type as one of the terminals of a Custom VI

Hello,
Can anybody tell me if it's possible and how to add a dynamic data type as one of the terminals of a sub-VI? I would like to have a terminal that I can connect signal from DAQmx to my sub-VI. Thanks.

Here is one of the coolest things about LV, and one of its major advantages over languages like VB - it has automatic memory management and it compiles whenever you make a change. This allows you to be very free in the way you handle data and change your code. In this case, you should note the small gray dot that appears when you wire the dynamic data into the Array of Waveforms input. This gray dot means that LV coerces the source data type (DDT, in this case) to the target data type (Array of waveforms). If it wouldn't match, you would get a broken wire, the VI couldn't run, and if you hover over the wire or press the broken run button you would get an exact description of the error. Cool, eh?
This can also be seen in other things. For example, you can change an array's data type or number of dimensions by simply doing it. This will automatically be reflected anywhere the array is called in the program, and if anything won't match, the VI will be broken. If you change the # of dimensions of an array, any array function which that array is wired to will adapt. This allows you to be very safe in the way you write code, because you have LV watching all that annoying stuff for you. You don't have to worry about misspelling a variable here (for the most part).
One important point about coercion - it does take processor power. This will usually only be evident in large arrays or loops, but it is an important point. Another thing is that coercing numeric types can cause you to lose data - coercing a DBL to a U16, for example, will cause you to lose all the fractional data.
To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here and here are a couple you can start with. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).

How do I Change the plot waveform colour on a Dynamic Data type Graph?

I have multiple different plots on different graphs, and I want to set the colours of the different waveforms.
In order to display the waveforms on different graphs, I switched to Dynamic data type and then split the wire
according to how many channels I have.
I can set the graph background colour with a property node, and create cursors of different colours no problem
using the array of references that I have created, so there is nothing wrong with my array of references or the property node.
As soon as I try and wire a colour box into the Plot>Plot Colour control, I get error 1055 out of the property node.
I was wondering if it was an error between the keyboard and the chair, but now I am thinking it is someting more sinister.
The Error box pops up and can't be dismissed remaining the focus until I run TASKKILL on LabVIEW and terminate it.
Any ideas on how to achieve my goal would be appreciated.
(LabVIEW 8.6)
Solved!

Hi Sheela,
It's 1 plot per graph, up to 4 graphs displayed on different tabs.

Attaching a Cluster of 2 elements data type to dynamic data type wire.

Hey Folks,
How do I attach a cluster of 2 elements data type of wire with a Dynamic data type wire?
Or a Build XY Graph to a curve fitting2.
Thanks for the help.
Ty

Hi Ty,
Try to use the "Express-VI Curve Fitting" which is at: Functions-> Signal Analysis -> Curve Fit.
You have to put this VI before the "Build XY Graph".
Otherwise, u can convert the siganls types by using the "Convert from Dynamic Data"
which is at : Functions-> Signal Mamipulation -> Convert from Dynamic Data.
Hope it Helps....

CAST Not working for me - Arithmetic overflow error converting int to data type numeric - error

GPM is DECIMAL(5,2)
PRICE is DECIMAL(11,4)
COST is DECIMAL(7,2)
Trying to update the Gross Profit Margin % field and I keep getting the "Arithmetic overflow error converting int to data type numeric" error.
UPDATE SMEMODETAIL SET SMD_GPM = (SMD_PRICE-SMD_COST) / SMD_PRICE * 100
FROM SMEMODETAIL WHERE SMD_PRICE<>0 AND SMD_QUANTITY<>0
Example record:
SMD_PRICE SMD_COST GPM%
1.8500 1.62 12.4324324324324300
I added cast and I still get the error.
How do I format to get this to work?
Thanks!

Hi GBerthume,
The error is caused by some value such as 1000.01 of the expression (SMD_PRICE-SMD_COST) / SMD_PRICE * 100 exceeds the
precision of the column(DECIMAL(5,2)). The example data doesn't cause the overflow error for the value of the expression is 12.43 which is in the scope of DECIMAL(5,2).
USE TestDB
CREATE TABLE SMEMODETAIL
SMD_PRICE DECIMAL(11,4),
SMD_COST DECIMAL(7,2),
SMD_GPM DECIMAL(5,2)
INSERT INTO SMEMODETAIL(SMD_PRICE,SMD_COST) SELECT 1.8500,1.62
UPDATE SMEMODETAIL SET SMD_GPM = (SMD_PRICE-SMD_COST) / SMD_PRICE * 100
FROM SMEMODETAIL WHERE SMD_PRICE<>0-- AND SMD_QUANTITY<>0
SELECT * FROM SMEMODETAIL
DROP TABLE SMEMODETAIL
The solution of your case can be either scale the DECIMAL(5,2) or follow the suggestion in Scott_morris-ga's to check and fix your data.
If you have any question, feel free to let me know.

Create dynamic data type in structure

Hi Experts,
I am new to ABAP.
In my scenario data type is varying for the field. for that I need to create dynamic data type in structure, this structure I am using for internal table for OVS search input.
Please suggest the solution for this.
Advance thanks,
Regards,
BBC

Thanks for your quick reply,
I used your logic like this.
data:
ls_component type abap_componentdescr,
lt_component type abap_component_tab.
*... (1) define structure components :
clear ls_component.
ls_component-name = 'NVALUE'.
ls_component-type ?= cl_abap_typedescr=>describe_by_name( <fs_seg_v>-fieldname ).
insert ls_component into table lt_component.
*... (2) create structure
data lr_strucdescr type ref to cl_abap_structdescr.
data lr_data_struc type ref to data.
lr_strucdescr = cl_abap_structdescr=>create( lt_component ).
create data lr_data_struc type handle lr_strucdescr.
field-symbols <fs> TYPE any.
assign lr_data_struc->* to <fs>.
your logic is working fine.
here I am getting feild name (<fs_seg_v>-fieldname) from internal table.
But I need to assign same field name structure to query parameter.
FIELD-SYMBOLS: <ls_query_params> TYPE lty_stru_input.
Please can you suggest how I can refer the field name structure?

Arithmetic Overflow error converting float to data type numeric

Hi,
Am facing strange issue,I have function which returns money datatype and assigning the return money value to float datatype in table.
Error msg:
Msg 8115, Level 16, State 6, Procedure GBCalcCatalogPriceNewV2, Line 204
Arithmetic overflow error converting float to data type numeric.
The statement has been terminated.
Strange thing is the same stored procedure is working fine in production environment,but in the deveopment i see this error.Am scared if the same happens in the production environment.Please advice and advance
thanks
Regards
RAj

Strange thing is the same stored procedure is working fine in production environment,
How could that be strange? This is an error that occurs depending on the data. Accidents that are waiting to happen will happen sooner or later.
Then again, a development database may be more prone to such errors, because data that entered are completely out of whack with real life data. Still it is a warning sign. If you have some place where you convert data from float to numeric, you must consider
the risk that the float value is outside the range for the numeric data type. How do you prevent that from happening? Maybe a CHECK constraint on the column? Of if the data origins from a money column, use a numeric data type with sufficient precision.

Arithmetic overflow error converting expression to data type int

Hi
iam creating on sp for the database total size , used mb and free size . percentage free .
in this purpose i was creating on sps, with in the sp iam was writing one select statement . it statement is
SELECT [Drivename] ,[DataSizedUsedMB],[DriveFreeSizeMB],DriveTotalSizeMB,
CAST( (DriveFreeSizeMB/DriveTotalSizeMB)* 100 AS NUMERIC(5,2))
As
[PercentFree] ,[DateRecorded] FROM
SELECT SUBSTRING([physical_name],1,1) AS Drivename,
CAST(((SUM(COALESCE(size,0)))*8)/1024 AS NUMERIC(20,2)) AS DriveTotalSizeMB,
CAST(((SUM( COALESCE( FILEPROPERTY( [name],'SpaceUsed'),0)))*8)/1024 AS NUMERIC(20,2)) AS DataSizedUsedMB,
CAST(((SUM(COALESCE(size,0))-SUM(COALESCE(fileproperty([name],'spaceused'),0)))*8/1024)AS NUMERIC(20,2)) AS DriveFreeSizeMB
,SYSDATETIME() AS [DateRecorded]
FROM sys.master_files
GROUP BY SUBSTRING([physical_name],1,1)) AS Data
it was executive one server with out error but the same select statement is writing antoher server iam geeting belo error.
"@ErrorDesc: Line 24 - Line 13- Arithmetic overflow error converting expression to data type int."
how to slove this issue..
please help me...

Change 8 to 8E0, to make it a float literal. The data type of
SUM(COALESCE(size,0)))*8)
is int, since all components are int, and it can easily overflow the size for an int. If you use 8E0, you get a float, and the entire expression will be float.

How to save the dynamic data from a pressure sensor

Hello Everyone,
We have a FPGA board NI cRIO-9073, a temperature module NI 9217 and a pressure module NI 9203. Right now we have problem with saving the data from pressure sensor. I succeed in getting and saving the data from the temperature sensor. Then I just simply modify the FPGA VI and host VI of the temperature function block which are shown in the attachment files.But I get an error saying I cannot connect two different data types.
Could anyone here give me a help on this?
BTW: we are using a 2 wired pressure sensor with 4~20mA. The brown one is +Vcc and the white one is GND.I connect the white one with the COM of NI 9203 and the brown one is connected to AI7. DidI make a right connection?
Thx for any help from anyone!

How to define MDM real data type in ABAP ?

Hi,
I want to fetch MDM Repository data using MDM API .
I am strugling as one field in MDM is of real type .
Please tell me how I could define Real data type field in ABAP ?
Thanks.
Sandesh

I recently had a Real type added to a repository I'm working on and noticed a dump in the API itself when trying to fetch data from that field. I'm running 5.5 so you may be experiencing a different issue. I haven't resolved the issue yet as it isn't a priority but I will most likely move to a string field and just ensure that the field has its decimal rule respected logically.

How to access the Custom Data type variable given in Expression edit control To and From LabVIEW

Hello, I would like to know how to access the custom data type variable given in the Espression Edit Control from LabVIEW and vice-versa
Say, the FileGlobals.Reference_Handle (Custom Data Type Variable) contains the
VISA I/O session (Which in turn contains VISA_DeviceName: String, Session: Number),
Channel1: Number and
Channel2: Number
I am expecting the user to give FileGlobals.Reference_Handle as the input at the ExpressionEdit Control in the edit screen of the VI Call.
I would like to know how to get the values of this custom data type to LabVIEW?
Say, if I have the Cluster in LabVIEW like VISA I/O session (Deive Name and Session Number), Channel1 and Channel2
how do i need to set this cluster to the Custom Data type variable in TestStand?
Thanks and Regards
Prakash

Hi,
TestStand to LabVIEW: i didnt understand what you r trying to achieve. But if you are using references, Use Property nodes and Invoke nodes to achieve what you want in LabVIEW.
LabVIEW to TestStand: check the image below: You need to click the button next to 'container'. I have used a cluster output in the VI.
Hope this helps
