Running two Eurotherm 3216 temperature controllers using the driver available from Labview

Hi All,
I am trying to control two Eurotherm 3216 temperature controllers using the driver provided by NI at http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=7F14CDCB24923797E04400144F1EF8.... Specifically, I am using the "Temperature Control Monitoring" example.
I have been able to operate a single temperature controller using this code. However, I need to operate two controllers, and I havent been able to modify the code appropriately to do it.
I initially tried just repoducing the entire code and running it but that provides me with an error. However, if I run the code while using "highlight execution" it works just as I need it to...except to slowly for my purpose.
If anyone has any insight as to how I may run both controllers, I would really appreciate it.
Thanks

Here something’s to try.
1)      Make sure both controllers have RS485 comms modules installed
2)      Connect both controllers in Daisy Chain configuration using the EIA485 instructions from Page 16 of the Manual you mentioned.
3)      Ensure both the KD458 and the 3216 controllers have identical Comms configurations. ie Baud Rate, Parity etc
4)      Verify your setup: In the "Temperature Control Monitoring" example” change the Unit Address, Baud Rate, Parity and Break Length to match the 1st controllers values. Verify that you can communicate with the 1st controller.
5)      Using the Same "Temperature Control Monitoring" example”, NOT a second copy, change the Unit Address, Baud Rate, Parity and Break Length to match the 2nd controllers values. Verify that you can communicate with the 2nd controller.
Comms problems are difficult to fault find so be methodical and you will succeed.

LabVIEW Program not running if i lock my PC (using an EXE made from LabVIEW)

Hi everyone
I observed some odd behavior when I was running my program on a PC. I prepared an EXE for a LabVIEW program, this am running on another PC. Purpose of the program is to read a text file and follow the command given in that text document, we are accessing parallel port, calling third party EXEs in this. It is not running when I minimize the window or lock the PC. Do we have any property in VI properties for this?
Please help me in this.
Thanks
Anil

Hi Anil,
Minimizing the application or locking Windows should not stop the executable from running. Can you reproduce this behavior on the development PC? Also try to create an executable with a simple VI that counts the number of iteration and check for this behavior ?

You likely have iCloud turned on in at least Safari. If you don't want Safari to sync between these devices turn one of them off. System Preferences - iCloud - Safari (uncheck the box)

Hi, thanks for the suggestion. I have tried as you suggested, and when opening the "purchased" apps some have the icloud logo next to them, but I only have "OPEN" against "Find My iPhone". When opening it up, it goes through the same routine; needs to be updated before proceeding, and wouldn't update because I don't have IOS8.
Anything else I could try, or am I doomed!
All of your help is much appreciated, thanks

Run exe file while i'm using the program

hi there how can i run exe file while i'm using the program

Hi,
Hopefully HOST() command will do it. For more info about HOST() command look for documentation. Hopefully it will work fine.

I just got a Touch 32GB yesterday and ran into the same problem. I have two PCs in the house that I can sync my iPods on, but I normally use one that DOESN'T have an internet connection, so that the one that does is free for others to use ... a great argument and tension solution, btw.
Anyway, I hooked up the older "iTunes" PC to the net for a first-time sync with the Touch, and ran into this problem. First it kept detecting the Touch as an unidentified iPhone, then I couldn't sync my classic either. Then I found a post here about how when multiple USB ports running off same USB controller seem to screw with the Touch/iPhone syncing.
So I disconnected all but 2 of my USB 2.0 slots (the Touch & the Portable HD with my iTunes Library) and now it's working perfectly. I don't know if this will solve your problem, but it might be worth a try.

How to use the pps function from JCOP?

Hi
I'm trying to use the pps function from JCTerminal (JCOP API: [url http://www.cs.ru.nl/~woj/jcopapi/com/ibm/jc/JCTerminal.html#pps(int, int)]pps function ) to connect my client to a virtual card with a specific protocol (T=0).
But I always got the error: "Protocol and parameter selection not supported by this terminal!"
I've tried to make an ATR that support both protocol : [url http://smartcard-atr.appspot.com/parse?ATR=3b909580811fc7dc]3B 90 95 80 81 1F C7 DC.
I really don't know what value to put in the second parameter (baud rate), I've tried with 150000, which is in the range of the ATR but I'm not sure this is correct. And I could't find any example of it.
I'm also not sure where to put the pps command, the specification say directly after a reset, so I tried this implementation:
System.out.print("Start");
 readers = TerminalFactory.getDefault().terminals().list(State.CARD_PRESENT);
 //If no readers has a card it ends the process
 if(readers.isEmpty()){
 System.out.println("\nNo card in the reader...");
 return;
 System.out.println("\nReader Type: "+readers.get(0).toString());
 term = (PCSCJCTerminal)JCTerminal.getInstance("PCSC", readers.get(0).toString().substring(15));
 term.open();
 System.out.println("\nTerminal opened");
 //Getting the ATR
 atr = new ATR(term.waitForCard(2000));
 try {
 term.pps(JCTerminal.PROTOCOL_T0, (int)150000);
 } catch (Exception e) {
 e.printStackTrace();
 System.out.println("ATR: "+toHex(atr.getBytes()));
 //sending a data 11223344
 System.out.println("\nsending data: 11223344");
 byte[] responsesend = term.send(0,cmdsend,0,cmdsend.length);
 System.out.println("Response data is:" + toHex(responsesend));
 //close terminal
 term.close();
 System.out.println("\nTerminal closed");I've got this output on the console:
StartReader Type: PC/SC terminal Virtual CAD Reader 0
Terminal opened
ATR: 3b 90 95 90 00 81 1f c7 cc

Protocol and parameter selection not supported by this terminal!

If someone know how to use this function or have any advice to help me to select a specific protocol with Jcop API, please let me know.
If you you need any more information don't hesitate to ask.
Best regards

I'm using a virtual terminal (windows driver), and I don't see how I could turn off the Auto-pps. I've also tried with a real reader and a card and I have the same error.
-2
I've tried value in the range of the atr (based on this analysis: [url http://smartcard-atr.appspot.com/parse?ATR=3b909580811fc7dc]http://smartcard-atr.appspot.com/parse?ATR=3b909580811fc7dc ). But I don't know if only I value of baud-rate is possible in the range. Anyway I just would like to change the protocol, not the baud-rate.

I've already tried to call pps function before, after the first reset, or with another reset later and I always got the same thing.
 term = (PCSCJCTerminal)JCTerminal.getInstance("PCSC", readers.get(0).toString().substring(15));
 term.open();
 System.out.println("\nTerminal opened");
 //Getting the ATR
 atr = new ATR(term.waitForCard(2000));
 System.out.println("ATR: "+toHex(atr.getBytes()));
 jcard = new JCard(term,atr,0);
 jcard.reset();
 try {
 term.pps(JCTerminal.PROTOCOL_T0, (int)312500);
 } catch (Exception e) {
 e.printStackTrace();
 }The same pps is always send after each reset...

My location is at INDONESIA but planning to use the SSD Hosting from U.S . Does it ADVISABLE?

What is the speed gap if i USE the SSD Hosting from Indonesia to compare with SSD Hosting from U.S?

Typically hosting services are not offered on specific hardware, rather than they offer specific SLA's (service level agreements). The choice of geographical location of where to host your data depends on where that majority of your audience are located.
For example, if you're looking to host a web site or web application that most of its users will be in the US, it would be a good idea to host it in the US. The latency will be lower. And vice versa. So, if most users are anticipated to be in Indonesia, I
would host it in Indonesia.
For example, if you're setting up a Storage account on Azure, and you're thinking which one of the 13 Azure data centers should I choose, you can run a
latency test like the offered here.
Results may look like:
The results will vary a lot based on where you're testing from, and they mostly reflect conditions related to the local Internet connection. I've seen this test show very different results on 2 circuits from the very same physical location..

Capture an image using the web camera from a web application

Hi All,
Could anyone please share the steps what have to be followed for capture an image using the web camera from a web application.
I have a similar requirement like this,
1) Detect the Webcam on the users machine from the web application.(To be more clear when the user clicks on 'Add Photo' tool from the web application)
2) When the user confirms to save, save the Image in users machine at some temporary location with some unique file name.
3) Upload the Image to the server from the temporary location.
Please share the details like, what can be used and how it can be used etc...
Thanks,
Suman

1) Detect the Webcam on the users machine from the web application.(To be more clear when the user clicks on 'Add Photo' tool from the web application)There's not really any good way to do this with JMF. You'd have to somehow create a JMF web-start application that will install the native JMF binaries, and then kick off the capture device scanning code from the application, and then scan through the list of devices found to get the MediaLocator of the web cam.
2) When the user confirms to save, save the Image in users machine at some temporary location with some unique file name.You'd probably be displaying a "preview" window and then you'd just want to capture the image. There are a handful of ways you could capture the image, but it really depends on your situation.
3) Upload the Image to the server from the temporary location.You can find out how to do this on google.
All things told, this application is probably more suited to be a FMJ (Freedom for Media in Java) application than a JMF application. JMF relies on native code to capture from the web cams, whereas FMJ does not.
Alternately, you might want to look into Adobe Flex for this particular application.

Difference between using app server connection pooling and using the driver

Hi all,
How to get connection pooling with out application server and tomcat also?
What is the difference between using app server connection pooling and using the driver supported connection pooling?
Regards,
Murali

maybe the performance of App server pool is better than the JDBC pool,
for you don't know wether the implementation of the JDBC interface is good or bad.

Problems in using the driver coming with application in Crystal Report

Post Author: StrongWare
CA Forum: Data Connectivity and SQL
Hi! All,
I used the ADORecordSet to fetch data from tables, and pass it to ther report at runtime using AddADOCommand.
I got the ActiveConnection and ActiveCommand from ADORecordSet and passed them as parameters of AddADOCommand, it seems the AddADOCommand opens an addional connection, which can be told from the ODBC trace, instead of using the ActiveConnection I passed in.
Is that true?
It causes the big problem for me, since the ActiveConnection I passed in was opened using our OEM DataDirect driver and I assumed the AddAdoCommand uses it directly, but it is not the case!! The AddADOCommand just uses the connection information from ActiveConnection and opens an additional one. Since the connection string contains the driver name, so this connection is also opened via our OEM DataDirect Driver. But the Crystal Report tries to unlock it using its own license/password {qecr.lic,brahmabrahmabrahmabrahma} to unlock our OEM driver, which of course raises the license warning from DataDirect Driver 5.2!! After a certain grace period, any sql operations under the cover of AddADOCommand fail and thus causing the failure of AddADOCommand.
Now what is the solution?
1. how to avoid open an additional connection? or any other API I should call to avoid this?
2. How Crystal Report works with the driver coming with the application, and this driver needs to be unlocked before being used.
Thanks
Strong

I don't have the any driver's source code (such as ividcpwr.dll source code), how can I modify the specific driver through labwindows.
Follow your advice I use I/O trace to get trace as follows:
1 IviDCPwr_InitWithOptions ("ke2303", VI_FALSE, VI_TRUE, "", 0x0C913064) VI_SUCCESS 14:45:10.675
2 IviDCPwr_ConfigureVoltageLevel (ke2303, "CHANNEL1", 3.8) VI_SUCCESS 14:45:11.405
3 IviDCPwr_ConfigureCurrentLimit (ke2303, "CHANNEL1", 0, 3) VI_SUCCESS 14:45:12.104
4 IviDCPwr_ConfigureOutputEnabled (ke2303, "CHANNEL1", VI_TRUE) VI_SUCCESS 14:45:12.824
5 IviDCPwr_Measure (ke2303, "CHANNEL1", 1, 0) VI_ERROR_TMO 14:45:16.207
6 IviDCPwr_GetError (ke2303, -1073807339, 0, "") 0x00000037 14:45:32.991
7 IviDCPwr_GetError (ke2303, -1073807339, 55, "Primary Error: ..................") VI_SUCCESS 14:45:32.991
8 IviDCPwr_close (ke2303) VI_SUCCESS 14:45:33.847
I cannot see any GPIB command in the trace but some IviDCPwr functions.
Besides, if I know any bug (eg. some wrong GPIB command) in ividcpwr.dll, how can I modify it before I get it's source code.
Pls teach me anytime in your conveneince.
thanks!

Can i have 2 Apple IDs using the same playlist from the same pc?

can i have 2 Apple IDs using the same playlist from the same pc?

Easiest way is to create separate computer logins with all your own info including your own iTunes library.
I recommend each individual not have more than one AppleID because you will have purchases on multiple accounts
You can use more than one AppleID in an iTunes library.
AppleID/iTunes =used for purchases.
iTunes library = iTunes and all media on your computer.

Load the drivers and you should then be able to add it in Print Center.
