How can I use DFProfi II to monitor a Gateway ?

Hi everybody
I am a total newby to Profibus, so excuse me please, if this is a silly question:
I have a Simatic S7 400 controlling (via Profibus) a robot application on a factory floor. The profibus network also contains a gateway slave to RS-232 which communicates with a LabVIEW RT image processing system. Basically the gateway (HMS-Anybus) is nothing more than a shared memory space which can be accessed from both the Profibus- and the RS-232 side which seems to me a very simple and efficient solution.
What I would like to do in order to investigate (existing???) timing problems in the system is the following:
I have a DF-Profi II in a PXI-Rack and would like to connect this to the Profibus network and use LabVIEW to watch/log the communication between the S7 and the RS-232 over the gateway.
Is this possible? Can anybody give me a few hints how to configure the DF-Profi II? It would have to be in "master" mode, wouldn't it ??
So that would make 2 masters (S7 + DF-Profi) on the bus then?
Any little bit of information is greatly appreciated
Thanks

Hello Hurban,
in my opinion, a Multimaster Network is what you need. See also this link:

Search for webcam apps in the app store. Most work only with specific cameras. Check the manufacturer of yours and see if they offer an iOS app.

How can i use my smart TV as a second monitor for my Power mac (2010) via HDMI cable? i've made the connection but no options show in system prefs display.
the computer:Mac Pro, Mac OS X (10.9.5), 2 x 2.66 Ghz 6-Core intel Xeon
the TV: LG Smart tv

The Mac uses a highly-parameterized universal Driver for every display. The parameters are set at certain times when a query is sent to your display. The display MUST answer with its name and capabilities, or the screen stays dark. A TV set that is off or "not paying attention" because it is set to a different port when the query occurs will rarely answer, and so will often remain dark.
You can use tools in the System Report to see whether your display has been detected at all. If it has, the report will look something like this, but its name will appear:
The times when the query is sent are:
• at Startup
• at wake from sleep
• when the Mac-end of the cable is inserted
• when using the Option ( Detect Displays ) button in displays preferences

I use two monitors at work and have no issue. I have my mail set to use Desktop 1 and iTunes set to the second monitor of Desktop 1. I have browsers set to Desktop 2 and Fusion and RDC set to Desktop 3.
Two things that may help you. In System Preferences > Mission Control, disable the setting "Automatically rearrange spaces...". This screwed with assigning applications to certain spaces. And the other thing is don't use full screen on apps that support it. This just makes your second monitor superfluous.

How can I use the built-in Isight camera with an external camera (usb/firewire) at the same time?

How can I use the built-in Isight camera and an external video camera at the same time?
I'm wanting to stream over Oovoo/Skype/etc. using 2 cameras.
Thanks

Simple question with a not so simple answer.
(a) If you mean that you want to run multiple apps simultaneously using a different camera with each app, you may encounter computing power limitations. Digital video is processor intensive. The only way to know if your Mac can do this it to try it. If the video does not work together but each app works when it it the only app running, you are likely overloading your Mac's ability to process and/or move all the required data in your data bus. You can get a better indication of whether this is the case by watching your Activity Monitor utility while running the apps you want to use.
(b) If you mean that you want to have more than one compatible camera connected to your Mac simultaneously for ease of changing between video sources, some, but not necessarily all, apps you are using to operate your camera(s) allow you to select between your cameras.
How you select among connected cameras depends on which application you are using. Here is how camera selection works in a few examples:
(1) For iChat, you can choose which iSight you use in the "Camera:" choices bar in iChat > Preferences... > Audio/Video that appears when more than one compatible camera is connected. Although your camera choices will be different, the choices bar will look something similar to the Preferences settings shown here:
If you cannot see the "Camera" choices bar, your Mac is recognizing only one (or none) of your cameras. In that case, consider the suggestions fromhttp://support.apple.com/kb/HT2090 for iSight problems or refer to your other camera's documentation for help.
This particular choices bar solution applies ONLY to iChat. Most other applications also have settings that allow you to choose which camera to use. However, they do not all work the same way.
(2) For instance, iMovie HD's camera choice is NOT set via Preferences. When you have more than one compatible camera connected, iMovie6 HD uses a drop-down menu choice something like this (depending on which version of iMovie you use):
Note: Because I had no built-in iSight connected when I made this example, and because my external iSight was not connected, the drop-down menu showed only "Time Lapse." Because your Mac has a built-in iSight, your built-in iSight would show in the drop-down menu even when no other camera is connected. Connecting an additional Mac compatible webcam should allow you to choose either camera.
Other iMovie versions work slightly differently.
iMovie 9 (from iLife '11) uses a different camera choice button shown in this article:
http://docs.info.apple.com/article.html?path=iMovie/9.0/en/mov39f84285.html
iMovie 8 (from iLife '09) is slightly different as explained in this article:
http://docs.info.apple.com/article.html?path=iMovie/8.0/en/10172.html
In general, you can use your Mac's help for the application in use to find out how to select among more than one connected camera.
(3) Photo Booth in Snow Leopard 10.6.x and later uses the Photo Booth > Camera menu command to select which camera to use.
Note for readers with older Mac OS X: The previous version of Photo Booth that came with Tiger (10.4.x) is such a simple, basic app that it offers no menu selectable choice. Unless your built-in iSight is already occupied as the camera being used by some open application before you launch Photo Booth, Photo Booth will use ONLY your built-in iSight.
However, you can use the trick from ¶ 4 of http://docs.info.apple.com/article.html?artnum=302781 to let Photo Booth use an external camera.
(If you have an external Firewire camera connected, it may be used in preference to any USB webcam. If that is a problem for you, merely disconnect the problem Firewire device.)
(4) For FaceTime, launch the app and click the Video menu item.
If your Mac recognizes more than one connected compatible camera, a "Camera" section listing the cameras from which you can choose will appear there. Clicking on the desired camera name will let you select the one you want as shown in this image from my Mac Pro and LED Cinema Display:
If your Mac recognizes only one compatible camera, the "Camera" section will not appear in the Video menu, but FaceTime will automatically use the connected camera that is recognized by OS X.
(5) I do not use Skype oir Oovoo. For those or other apps, see Help for each app for info on how to select your desired camera.

How can i use isight camera to broadcast to web with Mac OS 10.4?

I am using an iBook G4 running OS 10.4 as a printer server. I have to do this to be able to print on my HP DeskJet 882c printer from computers running OS 10.6 and above (although I have not been able to get it to work with 10.8).
I can connect an iSight camera to the iBook via FireWire. Can I set that up to broadcast a video feed to a web site so I can visually monitor the area near the laptop and printer?

jrmnewtonma wrote: How can i use isight camera to broadcast to web with Mac OS 10.4?
You could use compatible older versions of QuickTime professional extensions for your Mac OS X version.
This professional quality software is very powerful, and it will certainly stream any video you need. However, it is not simple to use, so be prepared to do some research and study to get it configured and working.
To use your iBook with its OS X 10.4, you will need QuickTime Broadcaster 1.5.3
and Darwin Streaming Server (v5.5.5) (if you need streaming server functions.)
Although I have never used it, QuickTime Streaming Server 4.1.1 might be a useable substitute for Darwin.

How can I use this RFC function

I just wanna create a monitor as same as TCODE ST06
so
I Added a TextBox, a Button and a DataGrid. and then everything has finished.as same as following step for "RFC_CUSTOMER_GET" from SAP connector 2.0 help
but how can I use the function? (VB.net 2003) I debugged the function in SE37 the function only need 1 parameters
so,I scratched some statments... but it is still not correct
        Dim num1 As Integer
        Dim dst As CPUSAPUSAGE.CPU_SINGLETable
        Me.SapProxy11.Get_Cpu_Single("local", "", num1, num1, num1, num1, "", num1, num1, num1, num1, dst)
please tell me details steps
Thank in advance.

Create a Windows Forms application.
Add an empty SAP Connection class with the ABAP functions
RFC_CUSTOMER_GET and RFC_CUSTOMER_UPDATE.
Leave the proxy designer open. Go to the SAP Proxy toolbox and drag the Proxy field icon to the designer.
Rename the new Field1 to Tab. Change the Type property to BRFCKNA1Table. To do this, use the drop down icon.
Note that the ReadOnly property automatically changes to true and the default value changes to new BRFCKNA1Table().
Add a second Proxy Field with the name Filter, the type String and the default value A*.
Select the Rfc_Customer_Get function and click on the button of the Parameters property.
Set the default values of the three parameters with the drop-down icon as follows:
Name1: Filter
Kunnr: Customer_T: _Tab
Save the proxy designer and switch to your Windows form. Add a TextBox, a Button and a DataGrid.
Add an instance of your SAP proxy to your Windows form, add a Destination and set the Connection property as described in A4.
Set the DataSource property of the datagrid to sapProxy11. Set the DataMember property of the datagrid to Tab. Alternatively you can set the DataSource to sapProxy11.Tab and leave the DataMember empty.
For textBox1 use the DataBinding feature to bind the Text property of the textbox to sapProxy11.Filter.
Double-click the button to create an event handler and add a single line:
this.sapProxy11.Rfc_Customer_Get_();
You are using sapProxy11 as a smart DataSet that contains the necessary state. You bind the state to the corresponding controls. The overload method Rfc_Customer_Get_() does not have any parameters, as the required state is already in the bound Proxy Fields.

Dim dst As New CPUSAPUSAGE.CPU_SINGLETable
