Interface GPIB with dc-ac inverter

I have built my own dc-ac inverter however I need to find out how to interface my inverter with LABVIEW so I can display the voltage and current and other power measurements

EE24,
If you also built a serial or GPIB interface into your inverter, you could use our serial or 488.2 boards. There are examples and built-in VIs (functions) in LabVIEW that will help you to communicate over these interfaces.
However, if you don't have these options, I highly recommend that you look into our E-Series Data Acquisition cards. You can achieve these measurements through the analog inputs. However, if you will be working with greater than just a few volts or milliAmps, you will need to use some sort of signal conditioning system to attenuate the signals a safe level for reading through DAQ hardware (or amplify / filter from a very low level to eliminate noise). An E-Series ca
rd, SCXI, and LabVIEW 7.0 with the DAQmx driver are a perfect combination.

Interface program with JDBC

I created three database tables in PostgreSQL database and interfaced it with JDBC.
In the interface program, I queried the program to retrieve data from two tables. I got results from the first table, but did not get any result from the second table. Rather, the system sent the following error message: Exception in thread "main" java.sql.SQLException: ERROR: parser: parse error at or
near "mdas_ar_coments"
at org.postgresql.core.QueryExecutor.executeV2(QueryExecutor.java:289)
Mdas_ar_coments is the name of the second table. I have checked the names, there is no spelling mistake in both the database tables and interface program.
Please, let me know how to query two or more tables in a JDBC interface program.
Thanks.

Please show me how you are attempting to query two tables using JDBC.

Conditional Interface Determination with Flat Files

Hello,
I have one sender interface (dummy) which could either hold a flat file or an XML file. On receiver side there is one system with two receiver interfaces, one should be used for the XML structure and one for the flat structure.
My requirement is to have a conditional interface determination with an (exclusive) OR logic. Pseudo code:
The XML structure has "submission" as root node. So I use the condition (/submissioin) EX to determine whether it is an XML file and I check with not(/submission) EX to determine whether it is a flat file. However the condition does not work using a flat file ("Unable to find an inbound interface"). Could it be, that the conditional expression never is true in case a flat file arrives? How can I achieve this requirement?
What I additionally do with the flat file is just calling a Java Mapping that sets dynamic attributes for a file receiver, the flatfile itself is dumped on a file system without any addtional conversion logic.
Thank you for your advice.

How can I ingnore a message in case a condition applies? I am just aware of the fact that you can ignore messages in case NO condition applies.
Couldn't you simply reverse the logic and use "not equals"? Or perhaps you can use the EX operator to alter your conditions... here is more info on the EX (exists) operator
Re: ConditionEditor: Check if element is empty
What is best practice in this case? Should I use a "dummy receiver"? However if I use a dummy receiver I think I would receive a "interface determination not found" error. How would you do that?
I've never found the need to work with dummy receivers so I cannot comment there.

Interface Matlab with java good links and info

HI All
i want to interface Matlab with java
i did search through the net but i haven't got nay good links and info
by that i mean the given links either not working or do work for old version of matlab ie R13
i have R14
IF you have already done that or
you have a really good links and info and steps
please post them here
thanks

It doesn't appear that Matlab is free, so i'd expect that's why you are having trouble finding download links.
Here's is an overview link

Interface-Mapping with a Fault Message Type

Hi,
we have an abap-proxy and some messages generated errors. The errors can be displayed via sxmb_moni. The proxy raises an "Application Error (Restart possible)".
Now I wanna transform the generated fault message (of the proxy) with a message mapping and send the output to a file.
My problem is, that it is not possible to define an interface mapping with the fault message as well as it is not possible to define a receiver determination.
Any ideas?
Thanks a lot
Regards
Wolfgang Hummel

Hello
As far as I know you can propogate the application error back to the calling application only in case of a Synch Interface? Are you making a Synch call where the proxy triggers a fault message, if yes then all you need to do is to make the change in XI to have the fault message for both the outbound and inbound message interfaces and then a corresponding fault message mapping and select this in the Interface Mapping and then the fault message will be sent to the source / calling application.
In the case of Asynch calls I don't think this is possible until you use a BPM. Have not tried this myself though.

Is a Steinberg C1 audio interface compatible with Garageband if not what is the best product

Is a Steinberg C1 audio interface compatible with Garage band? The unit does not show up in the audio devices window even though it is connected to the computer and all software downloads have been completed.

I have tried the driver(s) from Steinberg.net, and tried yet again yesterday. It actually worked for some reason. I have noticed the device ony ‘fires’ when restarting if you have it connected, and after the latest driver install, Garageband actually recognized it. Don’t know why though.

Interfacing Oracle with Microsoft SQL?

Hi,
My workplace uses Microsoft SQL server and I'm trying to encourage our IT department to install 10g express so we can make use of Application Express.
One problem is that the Apex application would need to access data stored in the Microsoft SQL server (there is no chance of converting it to an Oracle database anytime soon).
Are there any popular solutions for interfacing the two databases?
We would be looking at perhaps 100-500 queries on the Microsoft database per day, nothing very demanding.
Regards,
David

hinpong:
Thank you for the suggestion, I am open to other ideas. I am not sure what other tools are out there that will meet my needs.
Our IT department has written applications with Visual Studio and Ajax but is unable to maintain or fully debug them. They are not thrilled with the prospect of me writing a program that interfaces direclty with their database but a separate database and the web-based development environment of Apex is a possibility.
We have been planning on not linking the two databases at all but if our IT department were able to handle something such as setting up a script to replicate the data on a daily basis, perhaps we could get the link regardless.
We need to retrieve a part number, given a part name, from the MSSQL database, nothing more. This would only need to be retrieved when new records are being created.
What other tools would you recommend given this scenario?
The database will have about 30 fields, less than 100 queries per day, and up to 5 new records per day. It is not very demanding at all, in my opinion, and I wouldn't have a problem even writing something with php/mysql if that were an option but it is not.

David

Performance of GPIB (with Tectronix scope)

I have an ICS Electronics GPIB card and I'm using the Quick Basic
libraries that came with it to code a program that captures a section
of the displayed trace. The scope is a Tectronix TDS-210.
The first version of the program used the RS-232 port and I was
capturing 512 samples of the captured trace (out of a possible 2500
points). I am capturing thousands of traces in a sequential manner.
The throughput using the RS232 port was about 1 capture per second.
With the new code for the GPIB port, I can capture about 3 traces per
second. I was expecting a MUCH higher capture rate given that GPIB
has a stated transfer rate of at least 200k bytes per second.
So, my question is this: Is it typical that certain GPIB cards or
har
dware has effective transfer rates that are much below GPIB spec,
or is this a case where the command or instruction-processing within
the device (TDS-210 in this case) is incredibly slow?

FYI - re Tektronix 'Wavestar' - I have used this on Tek TDS/THS scopes,
and as far as I can see it is not 'built for speed'. It does a credible
job of downloading and archiving scope files, once one has deciphered the
cryptic interface. But as far as automating rapid i/o, I dont think it
can beat hand-coded software, BASIC or otherwise.
IMLE, data transfer specs are never really realized in real world apps
no matter what the application:
VME/VXI/PCI/GPIB/IEEE1394/RS232/USB1/USB2/IEEE802.11 etc.
fwiw, I would agree a dedicated NI PCI scopecard would most likely achieve the
fastest capture rate, but would not be less expensive than a TDS2xx/3xx scope,
esp when adding in Labview full system cost,
and software would be considerably more complex as NI canned apps are typically
very limited in functionality, and it takes considerable hair-pulling to
delve into their buggy libraries to get it to finally do what you want.

Installing a PCMCIA-GPIB with WIN-XP and I get an "Unknown Hardware Error"

no resource conflicts. Config settings for GPIB0 are slot#ffffffff 500 nsec bus timing. Card worked with win-me, and ver 1.2 of install s/w - help!

Hi Dave,
You should try using the lastest driver for the PCMCIA-GPIB interfaces. This is NI-488.2 2.1. You can find it in the Driver and Updates page.

Help with Sunny Boy inverter

I must talk with a SMA Sunny Boy Controller (that controls three Sunny Boy inverters) with a Rs485 interface. I'm using Labview 7.1 with Visa, trying to send it the command for turning the inverters on and off and for the set up of the required level of power. The instrument manuals are very complex and don't give any clear example.
Each inverter should answer to my request with a well defined Hex string but sometimes this string is not complete (in the central part...) and sometimes one of them doesn't answer at all.
It's not the first time I use Visa, but now I really don't know what to do and I'm in a hurry! Is there anyone who can help me? Have you something ready for talking with those inverters?
thank you in advance to everyone can help me.
Bye Carmen

Dear Carmen, Dear Andrea, Dear Everyone
I'm working on the same problem as you do. I want to communicate with a sunny boy via the RS232 port by using the Yasdi libraries. I tried to implement the Yasdi functions by using the "Call Library Function Node". I think the yasdiMasterInitialize worked but I couldn't get any response from the inverter. It’s the first time I use the "Call Library Function Node" so I'm not sure whether all the settings and connections are OK. I would be very pleased if someone could give me some advices how to communicate with the SMA sunny boy. Thanks in advance.

Input Triggers from GPIB with LabView

Hi all,
I am new to LabView (few days...)
I use LabView 5.1 with a GPIB interface, and a KEITHLEY 238 current source
measure unit. The detector is moved on a X-Y table with two stepper motors,
controlled by a Windows 95 software.
I would like LabView to record a measurement from the current source
measure unit each time the current source measure unit sends a trigger
through the GPIB interface.
I tried to use VISA sessions and "Wait for RQS.vi" to make LabView wait for
an input trigger from the GPIB, but it doesn't work..problems with VISA
class... What VISA class should I choose?
Do you think this is the best suited method for my application?
Thank You!
Norbert MAILLOT

NI 488.2 won't work because the NI stands for NATIONAL INSTRUMENTS and not QUANCOM. You have to use the configuration software and driver from your vendor. If the instrument driver uses VISA and if your vendor provides a VISA driver for their card, then you should be okay. If the driver has the LabVIEW GPIB functions or if the vendor doesn't have a VISA driver, then you will have to replace all of the NI GPIB functions with whatever functions your vendor provides. If they don't provide a set of VIs, you may have to use a Call Library Node to access your vendor's dll.

CC software shuts down after 1/3 of a second - launches entire interface, quits with NO error messae

Can anyone help on the specified problem?
I have wasted hours talking to people on the Adobe chat now.
I signed up for Student Creative Cloud yesterday. Started downloading and installing InDesign and Photoshop. Both programs shut down about 1/3 of a second after launching. The software launches with full interface and then shuts WITHOUT any error message.
I also tried to open InDesign projects that I copied from another computer. It will load them perfectly fine, but directly asks to save them and upon doing so it shuts down.
It this a technical issue? Account issue? Please help - deadlines are coming up.

UPDATE: I also downloaded and installed Muse and Premiere.
Muse works, Premiere, Photoshop and InDesign do not.
There were older CS6 trial versions of Premiere, Photoshop and InDesign installed on this computer. I deleted everything before I installed my subscription software.
Could that be related to something?

ASA 5505 Logging Issue - Warning: Configured logging host interface conflicts with route table entry

I am getting this warning on my ASA 5505 when I try to set up logging from my off site FW to the central FW, which is a 5510.
