Buffered Data And Counter Reads

Someone help me please....I need to do some fast digital data
acquisition with handshaking, which I think I can figure out. If anyone
has any hints on buffered data like that, please let me know. Also, I
need to read the status of three counters every time that handshaking
pulse comes in. I am not sure how to store the counter data in a buffer
(ie, hardware controlled)
I have to do it hardware controlled, because the DAQ rates have to
be fast....right around 1000 Hz or higher. Can someone offer any guidance
into how to do this? I believe I understand how to configure buffers for
the regular data recording and set up that handshaking, but I'm not sure
how to set up the counters so they write their values to a buffer (all
hardware controlled) when the handshaking pulse comes in.
If there are any books out there or anything, if someone could
tell me, I would be very appreciative. I always get the feelign grad
students are trying to do things that the hardware wasnt designed for. LOL
Thank you.
JP

I am working on a project of high speed generation, and what I did was first to
look at the spec sheets of the 6533 (32HS) at www.NatInst.com That is a board
that buffers input and stores it till need be. The 6602 board has counters on
it that can be scanned when events happen. A small bit of math resulting from
those numbers can tell you a lot about when such triggering events happened.
Hope this helps,
Dave

Load Date and Count query implementation in ODI

Hi All,
I have two different questions.
1. How to implement load_date to the SCD Type 2 Dimension tables and fact tables? For the SCD Type 2 Tables do I have to say "Add a new record" for Load date? In the Target store it will be Current_Time_Stamp, is thsi correct?
2. I have the following query I need to add for a column in the target data store.
select SUM(CASE
WHEN CAST(a.LAST_IDP_UPDATE AS DATE) BETWEEN dateadd(month,-6, CURRENT_TIMESTAMP) and DATEADD(day,-1,current_timestamp) THEN 1
ELSE 0
END ) AS six_months_update from transactions;
this will be assigned to six_months_update column in the target. Transactions is the main table in this mapping.
When I use this in the mapping and verify it, it says error. I am not using the keyword "Select" or "AS six_months_update from transactions" in other words the mapping column looks like this
"SUM(CASE WHEN CAST(a.LAST_IDP_UPDATE AS DATE) BETWEEN dateadd(month,-6, CURRENT_TIMESTAMP) and DATEADD(day,-1,current_timestamp) THEN 1 ELSE 0 END )".
How do I implement this? Thanks for your time and help.

Does the alias "a" on your column match the source table (transactions) alias in the Interface? What error are you getting when it doesn't work?

VB 2012 - Help Finding Specific Numbers in a Database Column and Count the Number of Times They Appear.

Hello,
I am doing a project that uses MS Access to access data about a baseball team . The MS Access Database provides the names, addresses, and age of the players. All the players are 12, 13, or 14 years old. I need to display the average age for the team on a
label, which was easy. The problem is that I also have to display the number of players who are 12, 13, and 14 years old and I have no idea how to do that.
Here is my code so far:
Public Class frmBaseball
Private Sub TeamBindingNavigatorSaveItem_Click(sender As Object, e As EventArgs) Handles TeamBindingNavigatorSaveItem.Click
Me.Validate()
Me.TeamBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.LittleLeagueDataSet)
End Sub
Private Sub frmBaseball_Load(sender As Object, e As EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'LittleLeagueDataSet.Team' table. You can move, or remove it, as needed.
Me.TeamTableAdapter.Fill(Me.LittleLeagueDataSet.Team)
End Sub
Private Sub btnAges_Click(sender As Object, e As EventArgs) Handles btnAges.Click
Dim strSql As String = "SELECT * FROM Team"
Dim strPath As String = "Provider=Microsoft.ACE.OLEDB.12.0 ;" & "Data Source=e:\LittleLeague.accdb"
Dim odaTeam As New OleDb.OleDbDataAdapter(strSql, strPath)
Dim datAge As New DataTable
Dim intCount As Integer = 0
Dim intTotalAge As Integer
Dim decAverageAge As Decimal
odaTeam.Fill(datAge)
odaTeam.Dispose()
For intCount = 0 To datAge.Rows.Count - 1
intTotalAge += Convert.ToInt32(datAge.Rows(intCount)("Age"))
decAverageAge = Convert.ToDecimal(intTotalAge / datAge.Rows.Count)
Next
lblAverage.Visible = True
lblAverage.Text = "The average age of the team is " & decAverageAge.ToString("N2")
lbl12.Text = "The number of 12 year olds is "
lbl13.Text = "The number of 13 year olds is "
lbl14.Text = "The number of 14 year olds is "
lbl12.Visible = True
lbl13.Visible = True
lbl14.Visible = True
End Sub
End Class
I think I should use a For..Next loop but I don't know how to identify and match using this database, and then count how many repeated 12, 13, 14 years old there are.
Any help would be really appreciated.

Hello,
Conceptually speaking you would group the data and count. Beings this is school work the demo below is a static example and not suitable for your assignment, its to show a point. Now if you have learned about LINQ and Lambda this logic can apply to your
question but need to work out using this your data which can be done. If not look at using SQL Grouping.
Example of SQL grouping and count
select country, count(country) as count from customers group by country
Module Module1
Public Sub GroupingDemo()
Dim dt As DataTable = SimulateLoadFromDatabase()
Dim TeamData = dt.AsEnumerable.GroupBy(
Function(student) student.Field(Of Integer)("Age")) _
.Select(Function(group) New With
Key .Value = group.Key,
Key .Info = group.OrderByDescending(
Function(x) x.Field(Of String)("Name"))}) _
.OrderBy(
Function(group) group.Info.First.Field(Of Integer)("age"))
Dim dictData As New Dictionary(Of String, String)
For Each group In TeamData
Console.WriteLine("Group: {0} count: {1} ", group.Value, group.Info.Count)
dictData.Add(group.Value.ToString, group.Info.Count.ToString)
' The following is not needed but good to show
For Each item In group.Info
Console.WriteLine(" {0} {1}",
item.Field(Of Integer)("Identifier"),
item.Field(Of String)("Name"))
Next
Next group
Console.WriteLine()
Console.WriteLine("This data can be used to populate control text")
For Each Item As KeyValuePair(Of String, String) In dictData
Console.WriteLine("{0} {1}", Item.Key, Item.Value)
Next
End Sub
Private Function SimulateLoadFromDatabase() As DataTable
Dim dt As New DataTable With {.TableName = "MyTable"}
dt.Columns.Add(New DataColumn With {.ColumnName = "Identifier", .DataType = GetType(Int32),
.AutoIncrement = True, .AutoIncrementSeed = 1})
dt.Columns.Add(New DataColumn With {.ColumnName = "Name", .DataType = GetType(String)})
dt.Columns.Add(New DataColumn With {.ColumnName = "Age", .DataType = GetType(Int32)})
dt.Rows.Add(New Object() {Nothing, "Bill", 13})
dt.Rows.Add(New Object() {Nothing, "Karen", 14})

Choosing a value based on newest date, and newest value

Good Afternoon,
I'm in search of help on a statement Im trying to perform in a Query transform in my ETL. So this is the scenario. I have a Value called SGSGVL which is "CYW" and in our descriptions table for the VALUE CYW we have 3 different Descriptions like Cadium Yellow, Cadium Yellow Paint and CDM Yellow and the date the description was added. What I would like to do is say:
Where in the description table = CYW, select the newest date and the most used value.
I've been told I can use a MAX statement but Im unsure exactly how to perform this in the query transform. Can anyone help? It would be GREATLY appreciated!
Thanks!

You won't be able to do what you are asking in one query transform - it is complicated due the fact that you need your "max" to be based on something other than the column you want returned (date and count, versus the description). Essentially, what you need to do is:
QUERY1: value, description, field named REC_CNT with mapping of count(*), field named MAX_DATE with mapping of max(date), group by value and description
QUERY2: reads from QUERY1 --> value, field named MAX_REC which has a mapping such as: max(lpad(REC_CNT,'0',5) || '_' || to_char(date,'YYYYMMDD')), and group by value only
QUERY3: also reads from QUERY1 --> value, description, field named THIS_REC which has mapping such as: lpad(REC_CNT,'0',5) || '_' || to_char(date,'YYYYMMDD'), no group-by
QUERY4: joins QUERY2 and QUERY3 on QUERY2.MAX_REC = QUERY3.THIS_REC. Pull the value and description from QUERY3.
Basically - QUERY2 gives you the list of records which are considered the max, and QUERY3 gives you the full list with the same column to be able to join on, so QUERY4 pulls the descriptions only for the max record.

Floating Date and Time icon is gone in Leopard

This may seem like a trivial matter, but under Tiger I was able to have the date and time "Calendar and Clock" Icon on the desktop. It was handy to look at quickly for reference. Under Leopard, I can't seem to get it back. I can have date and time in the menubar, but not the floating icon on the desktop. Did they drop this idea in Leopard?

I saw this hint, but it seems a bit technical to be generally useful.
http://www.macosxhints.com/article.php?story=20071111053947248
A better hint may to enable Dashboard Development Mode

and find a widget to your liking that displays date and time.

July 2008       -       0           -             2
Do you have any example of formula to set-up in Crystal Report ?
Thanks in advance
Alex
Edited by: Alexandre VANNIER on Jul 22, 2008 3:29 PM

For the 1st Proposal, I can't do a left outer joined because my extract come from a Java Bean, so the DataSet is unique without any Table link, so I don't know how to generate this Month fields.
Concerning the Second proposal, I don't well understand how to do 2 types of Group,
      - I succeed to group by "Create Date" and Count, but I've no clue, how to re-use this count
      - How I can group again on a Second Parameter "Complete Date", then count and extract this value
Thanks for your help

HT5438 Stuck on setting date and time

Apple TV stuck on setting date and time

I read in another discussion that you can turn off your routers firewall temporarily and it will work. I did that. I turned off my apple tv (3rd gen) and then I turned off my routers firewall. Then I turned my apple tv back on and made sure the time setting was set to automatic. Then it let me set my iTunes login and everything was fine. I turned my firewall back on and it all works now. Try that. I'm not saying it will work for everyone, but it worked in my case.

MIO 6601 Counter, Perform Buffered Read and Simple Read

I have an application written in C++ where I would like to use the 6601 as the time base for all of the boards, so I would like to be able to query the current value of the counter. I also have a external signal that I want time tagged in the buffer. I have used example programs for the Simple Read and the Buffered read and they both work successfully individually.
If I try and combine them by setting up the counter with the following statement:
iStatus = GPCTR_Set_Application(iDevice, ND_COUNTER_3, ND_BUFFERED_EVENT_CNT);
and try to read the current value of the counter with:
iStatus = GPCTR_Watch (iDevice, ND_COUNTER_3, ND_COUNT, puiCurrentTime);
I always return a 0 for puiCurrentTime.
Can
I do both with a single counter? If not can I synchronize two counters one setup for the buffered read the other for the simple read.
Thanks

The second NIDAQ function call (GPCTR_Watch) will not work with Buffered Acquisition, because it is designed for simple read only. That might be the reason why puiCurrentTime always returns a zero.
Regarding the second issue, you can do both tasks with a single counter, by configuring it as buffered first, and completing the operation, and then configuring it as single, and completing also the operation. Nevertheless, there is no way to configure it as buffered and work with it as single reader, or viceversa. You must use two for performing an operation such as that. Thus, if you want to synchronize both of them, I would suggest you to read the following document which talks about it.
Well, I hope all of this info is helpful for you.

Sychronize AO/AI buffered data graph and measure data more than buffer size

I am trying to measure the response time (around 1ms) of the pressure drop indicated by AI channel 0 when the AO channel 0 gives a negetive single pulse to the unit under test (valve). DAQ board: Keithley KPCI-3108, LabView Version: 6.1, OS system: Win2000 professional.
My problem is I am getting different timed graph between the AI and AO channels every time I run my program, except the first time I can get real time graph. I tried to decrease the buffer size less than the max buffer size of the DAQ board (2048 samples), but it still does unreal time graph from AI channel, seems it was still reading from old data in the buffer when AO writes the new buffer data, that is my guessing. In my p
rogram, the AO and AI part is seperated, AO Write buffer is in a while loop while AI read is not. Would that be a problem? Or it's something else?
Also, I am trying to measure data much larger than the board buffer size limit. Is it possible to make the measurement by modifying the program?
I really appreciate any of your help. Thank you very much!
Best,
Jenna

Jenna,
You can modify the X-axis of a chart/graph in LabVIEW to display real-time. I have included a link below to an example program that illustrates how to do this.
If you are doing a finite, buffered acquisition make sure that you are always reading everything from the buffer for each run. In other words, If you set a buffer size of 5000, then make sure you are reading 5000 scans (set number of scans to read to 5000). This will assure you are reading new data every time you run you program. You could always put the AI Read VI within a loop and read a smaller number from the buffer until the buffer is empty (monitor the scan backlog output of the AI Read VI to see how many scans are left in the buffer).
You can set a buffer size larger than the FIFO
buffer of the hardware. The buffer size you set in LabVIEW is actually a software buffer size within your computer's memory. The data is acquired with the hardware, stored temporarily within the on-board FIFO, transferred to the software buffer, and then read in LabVIEW.
Are you trying to create a TTL square wave with the analog output of the DAQ device? If so, the DAQ device has counters that can generate a highly accurate digital pulse as well. Just a suggestion. LabVIEW has a variety of shipping examples that are geared toward using counters (find examples>>DAQ>>counters). I hope this helps.
