One host vi for two singleRIO 9632?

I am now working on a project.We have two singleRIO Board 9632 ,Each of which can be used to control a motor independently . Relative requirements are as following:
   1. In each singleRio 9632,A FPGA VI implements PID control and RT VI generates reference points.
   2.  Two singleRio 9632s can exchange data in real time by using Ethernet.
   3.We hope we can use one hostvi on my computer to supervisor two singlebord9632s .
I am not sure how to implement the hostvi which can make the whole vi run without particular running RT VI when the power of singelboard turn on.
Thanks a lot.

Hello,
What would you like to do from your host vi? Do you just want to view the status of your controllers, do you want to be able to start/stop the VI from running on your controllers? There are many options. The easiest way to do this would be to use shared variables to control the state of your two signle board rios. You probably want a variable that each board controls that specifies whether the board is connected or not. You could also use the RT Get Target Information.vi, and have it try to discover which devices are connected.
If you are passing large amounts of data between your single board rios and the host vi I recommend using network streams: Lossless Communication with Network Streams: Components, Architecture, and Performance
If you are interested in being able to remotely start a VI on one of your targets here is a KB that should help: Programmatically Launch an Executable or VI on a Real-Time Controller
I hope this information helps!

Can I activate one gift card for two different apple ID and use amount from gift card like bank account?

No, an iTunes gift card can only be redeemed onto one account, and it can be used to buy content for that account (you can't, for example, redeem it on an account and then use some of it for gifting content to another account).

Here's the deal: The SLA permits the "sharing" of content with up to 5 family members in the same household. Any other distribution of content is considered stealing...the SLA does not give you the right to distribute content in any way, shape or form. Its really that simple, and "friend" is NOT a family member living in the same household.

JTable - One Column Heading for Two Columns

Can you adjust the default JTable to have one column heading for two columns of data? Is there a simple span command? I've looked at the api for JTable and JTableHeader and didn't see anything, is there something I'm missing? Any help would be appreciated.

What i am trying to accomplish is have column 'E' span 2 columns.
This is my code thus far, however it give the error from my pryor message. I am pretty sure it is because I'm using and Object[][] and a String[] instead of Vectors. What corrections do I need to make in order for my goal of:
[ A ][ B ][ C ][ D ][ E ][ F ][ G ]
[ 1 ][ 2 ][ 3 ][ 4 ][5][6][ 7 ][ 8 ]
Object[][] data = new Object[ROWS][COLUMNS];
String[] columnNames = {"A","B","C","D","E","E","F","G"};
table = new JTable(data, columnNames);
table.setBackground(Color.white);
table.addKeyListener(this);
DefaultTableCellRenderer d = new DefaultTableCellRenderer();
d.setHorizontalAlignment(JLabel.CENTER);
table.setDefaultRenderer(table.getColumnClass(0),d);
for (int i = 0; i < table.getColumnCount(); i++){
TableColumn aColumn = header.getColumnModel().getColumn(i);
TableCellRenderer renderer = aColumn.getHeaderRenderer();
if (renderer == null) {
renderer = new DefaultTableCellRenderer(){
public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column){
JTableHeader header = table.getTableHeader();
if (header != null) {
setForeground(header.getForeground());
setBackground(header.getBackground());
setFont(header.getFont());
setHorizontalAlignment(JLabel.CENTER);
setText((value == null) ? "" : value.toString());
setBorder(UIManager.getBorder("TableHeader.cellBorder"));
return this;
aColumn.setHeaderRenderer(renderer);

Sharing Music: using one iTunes account for two users on one MacBook Air

I'm trying to set up my parents on their new MacBook Air and I have set up an account for each of them. To keep their music collection simple & compact I want them both to use one iTunes account on the one machine. Can two separate users work off the same iTunes account on the one machine?
I have tried the Home Sharing function but this seems to be for separate machines rather than accounts.
I have also tried putting the music into a shared folder but this hasn't worked properly for me as the secondary account is able to purchase (but not download) the music correctly from iTunes.
Any help appreciated. Thank you.

Creation of one outbound interface for two diferent senders

helo.
i just want to conform ont thing that .
my scenario is two diferent files from 2 diferent business systems are sending to one Rfc.
so i was created only one outbound interface for both senders and one message type bcos the file structure is same for both senders.
so is there any thing wrong in creating only one datatype,message type,message interface for both senders.
waiting for your response.
cheers.
seeta ram.

Hi Ram,
That is perfectly correct when you have two senders and one receiver Scenario and <b>Business Service is different</b>. Then you can use the same Interface.
Just keep in mind that the key for XI to recognise the Right interface is combination of these 3 parameters:
Sender Service, Sender Interface and Namespace. These cannot be duplicated.
When the Message type is same in the sender input data then you can create just one Message Type and One Data type and RFC is anyhow the imported RFC which you need not have to worry.
In Configuration Scenario you need to configure separately the RD, ID, CC and Agreements for the Interfaces.
Hope this answers your query. Let us know if you need anymore clarification
Thanks

One down payments for two customers

I have one payment received for one bank account and it is for the two customers.
Ex : Down payment received USD 100
Customer A USD 75
Customer B USD 25
How can I post these values for both of these customers & bank account from one entry by using f-29
Or is there any other method if F-29 is not possible.
Thanks
Nadeesha

Dear,
Please use the transaction code F-02 to post as per your requirement. You have to give the posting key as 29 and customer code with special GL indicator , and the same next line then 50 bank account 100. Check your document type give DZ.

One Controlling Area for Two CoCds with different Fiscal Year variant

Hi,
I have a Company code with FYV "A1" with 12 Periods (Apr - Mar) - Fiscal year start at Apr-01 and ends Mar-31 of the next year.
I have another company code with FYV "B1" with 12 Periods (Jan-Dec). - Fiscal year start at Jan-01 and ends Dec-31.
Chart of Accounts for both the company code is same.
Can I assign these two company codes to one Controlling Area?
When I try to assign the company codes, I got the following warning message.
Differing fiscal year variants: A1 - B1
Message no. KT297
Diagnosis
Fiscal year variant A1, controlling area 1000, does not agree with fiscal year variant B1, company code 5001.
The following entries must agree:
- Same number of posting periods (the number of special periods may vary)
- Same period limits
Procedure
Ensure that the fiscal year variants of the controlling area and the assigned company codes agree. If necessary, maintain the fiscal year variants.
1. What is the meaning of "Same period limits"?
2. Does it mean the fiscal year start and end date must be same?
3. What is the impact of the warning message?
Thanks
Palani

Having same fiscal year variant is one of the requirements for different company codes to be under one controlling area.
The FYV for the company codes and the controlling area can have a different number of special periods. The number of posting periods must be the same.
Impact of warning message: You cannot create one controlling area for both company codes (1:n assignment).
If you like, you can create one controlling area for one compnay code with FYV A1 and another controlling area for another company code with FYV B1.
PS: Please reward the points if you find the answer as useful and rewarding points is a way of saying thanks.
