Connect from a sensor to a DAQ

Please help. What else do I need to connect my RGB senser to a DAQ. i just need to see the signal output on my PC. Please help. What type of hardware do I need?
The sensor has 0V and 24V ( sinking and sourcing)Thank you for your time and help.

Hello Mr. Chad:
Thank you for your reply. The sensor is NPN cZ-K1 from Keyence corp( fiberoptic). The output circuit shows: brown 12 to 24V, Black (load) 5 to 40 VDC, blue 0 V.
This sensor detect color change ( 7 different light). My project is just to detect the change of color ( output) so I can save the output to a text file using labview. Please help Mr. Chad. May I ask what hardwares do I need? How do I connect to the DAQ. Thanks again.

How can I connect 1-wire sensor using DAQ?

Hi,
How can I connect 1-wire sensor using DIO in DAQ? I didn't find anything about it on this site.
Thanks.

Hello Depablo,
When making any voltage measurement you need to provide two wires and signal and a reference voltage. If you have a digital sensor or device with a number of outputs there should also be a reference or ground voltage output so that you're measurement device can read the correct value. If you don't connect the ground/reference voltage to the DAQ device then you'll be measuring a floating voltage and it won't be accurate. Voltage is a relative measurement--your sensor may be outputting 5 volts relative to its internal ground, but that ground may be 10 volts above your DAQ cards ground. If you measure the 5 volt line with your DAQ card you'll read 15 volts and not 5 volts unless you also connect the sensors ground to the DAQ card. If you're unsure which wire to use as a reference you can either contact your sensor manufacturer, or if you like you can post back with a link to your sensor's data sheet and I can see if I can identify the correct wire.
I hope this helps, and have a great day!

How to create a table with 3 inputs one of which is received from a sensor and the other 2 are constants

i want to create a table that has 2 angles (beta and theta) that could assume values from 0 to 180º and gamma that is given from a sensor to the table at every moment... all angles depend of each other and i want a table that demonstrates that. so i can pull a data to use it in a equation. can someone help with this mess?

alufe wrote:
I have to make an array for each angle and connects them?
That's one way. You end up with multiple 2-D arrays. You also could make a 3-D array to iterate through all your beta/theta arrays, calculating a gamma for each pair, if you understand arrays of multiple dimensions. You seem to indicate a major shortfalling in your math skills here, so I'll repeat, work with your teacher until you can understand the math, and then work on the programming.
You have to know what you want to do before you can do it. In this case, you have to know what that array represents, and how (I'm talking math now) you are going to determine/represent the one set of numbers you need to work with for each experiment before you set something up in software.

Connecting a pH sensor to an A/D converter then to computer via LPT1

Hello,
I am new to Labview and am having some problems getting data from my sensor. I have my sensor connected to an a/d converter which is connected to my computer. I am now trying to build a VI to read the pH data from my sensor, however I have not been able to do this...perhaps mostly due to my inexperience with labview. Could someone please advice and help? thank you very much.

Hi,
You can do a search for parallel port at www.ni.com. You'll probably find some interesting articles and example programs.
Here's the link to a tutorial on using the parallel port in LabVIEW:

Reading CAN frames from 10 sensors Simultaneously

Hello,
I have developed a code that reads CAN data frame from the CAN port (PCI CAN/2 series 2 board). The board have 2 CAN ports. I have connected a sensor to one of the ports and reading the CAN frames using my code. I want to use the same code to read CAN frames from 1o sensors simultaneously. Can anyone help me? I have tried creating SUB VI of my code but it reads only one port at a time.
Thanks in advance
Solved!

Hi Gruenberg,
I have one question....in my code the while loop interates at 1000ms i.e. I want to read CAN data every second (1 value per sec). But when I log this data I see that it gives me 11 values per sec. Because of this my log file is getting very bigger unnnecessarily. I tried to figure it out but couldn't find any solution. Can you tell me why this is happening?
Please see attached docs.
Thanks in advance.

HTTPs connection from SAP WebAS

Hello,
I have to establish a connection from SAP WebAS to an iSaSiLk server via HTTPS.
The iSaSiLk authentication is based on client certificates.
I've created a SSL client PSE, generated the Certificate Request, imported the certificate response and the chain of certificates associated with no errors. When testing the connection we're getting the following error message:

From the iSaSiLk everything seems to be OK, but on the SAP WebAS the error "none of the PSEs registered with hSsl can suffice the negotiated SSL cipher suite" is really unclear, since the cipher chosen by the iSaSiLk is one of the ciphers sent by SAP WebAS...
Can anyone give me any suggestion?

An iSaSiLk server "is a Java programming language implementation of the SSLv2 (client-side), SSLv3, TLS 1.0 and TLS 1.1 protocols. It supports all defined cipher suites (except for Fortezza), including all AES and PSK cipher suites. iSaSiLk implements all standard TLS extensions, comes with an easy to use API and operates on top of the IAIK-JCE Javau2122 Cryptography Extension. iSaSiLk is highly configurable and will work with any alternative JCE implementation supported by a proper provider for supplying the required cryptographic algorithms".
Once again thanks for your answer.

Cannot send email via ActiveSync when user connect from Internet (Exchange 2010 SP3 RU5)

Hi All.
This is the first time I encounter this kind of issue, whenever user connect from the internet they cannot send email from their Phone or Windows Mail App, but they can retrieve email
But when they connect from Internal Network they can send email. I already test ActiveSync from internet using www.testexchangeconnectivity.com and it pass all tests.
I also check the Firewall and all the necessary ports already opened (we even open all ports) , the default TTL on the firewall 3600 second.
From what I read ActiveSync use some kind of HTTP POST or in MS terminology "PING" command, but still have no idea what kind of configuration that should be made to the Firewall so it can pass this "PING" command. Because from what I
see in Android Logcat the problem always related to this PING command

Hi ronaldosy,
How about the work flow of Outlook or OWA on PC internally/externally?
If only phone has this issue, I suggest ask ActiveSync Forum for help so that you can get more professional suggestions. For your convenience:

Dbcon connection from sap db2 to external sql server

Hi ,
I am trying to connect from my sap server which is in unix platform with DB2 database to external SQL server using DBCON as MSSQL_SERVER=<server_name> MSSQL_DBNAME=<db_name>. But while running ADBC_TEST_connection i am getting the error . When i check the error log it says

How to resolve this issue. As it was mentioned in few forum we need to download the dbsl library from kernel patches and to load in kernel path. As my db is DB2 can we download dbmssslib.so this library and load in kernel file? Is it will work?
Regards,
Rai

Hi Rai,
This error indicates that the ABAP stack could not find the SAP DBSL for SQL Server (dbmssslib.dll) in the kernel directory. If you encounter this error on a Unix - based server the root cause is clear: the DBSL does not exist for other platforms than Windows or Linux x84_64. In this case use a Windows-based or a Linux x86_64-based SAP Application Server to establish the connection. If your system does not contain a Windows-based or a Linux x86_64-based Application Server you need to setup a small one as workaround. If you encounter this error on a Windows Application Server or a Linux x86_64 based Application Server make sure that the DBSL is properly installed in the kernel directory as explained in the document below.
For more details on configuration and troubleshooting refer to below SCN document

Remote Connection from SAP to MS-SQL server

Hello Experts,
We have been following 2 options so far and we have come across some issues
The first Option is to call a stored procedure (this is our preferred method) which does the data transfer for us
We have been able to test this scenario successfully from SQL Server side
However, while calling the stored proc via native SQL from ABAP we have come across an issue which is due to SQL 2005 changes (Schema implementation and difference in the security context)
While calling the stored procedure from the ABAP Code we have an error
The program short dumps with runtime error DBIF_DSQL2_SQL_ERROR, exception CX_SY_NATIVE_SQL_ERROR. The database error code is 15274, and the error text is
"Access to the remote server is denied because the current security context is not trusted."
This issue is new after the SQL Server 2005.
We are trying to resolve that.
Secondly we have been trying the DBCON option as well as per OSS Note 323151
We have a few things thatu2019s impacting our scenario:
The remote servers are in a different domain
The remote servers are located in DIZ
Remote server is a named instance
Remote server has been configured with a different port than standard (1565) u2013 All Connection strings will need port in there
The Database name starts with a numeric value
Due a combination of factors as mentioned above the standard approach does not work
Have any of you used this approach while connecting from SAP to MS-SQL server? Do you know of any successful methods to connect to SQL using ABAP (or not) from SAP.
Thanks in advance,

Yes,
DBConnect & UDConnect.
Works like a charm.
We write data into a MS-SQL database via DBConnect & an ABAP program (using open sql).

SAP DB Connection from SAP BI on HP UNIX to MS SQL External Database

Dear All,
Greetings!
I have a scenario to configure a SAP DB Connection from SAP BI System on HP UNIX 11i to the external legacy system MS SQL 2000 Enterprise for data upload. I am interested in connecting the SQL server as a Source System to the BI System.
I read through documents mentioning about installation of a Client driver in the SAP BI System, I also downloaded the JDBC client software and tried installing the same, but the steps as mentioned Setting the CLASSPATH or connecting to the server did not work.
Please help me in connecting the SQL Server as Source System, I would like to know in detail about the same - so kindly help me with the links to documents and guides about the same.
Thank you
Regards,
Vineeth Damodar

Short answer: this does not work.
Long answer: To connect directly to the database you need
- a database client for the source system
- a database interface library for the source system
Both of them are not available for HP-UX if the target database is SQL server --> doesn't work.
What you can do is: add a Windows application server to your BI system (heterogeneous installations work and are supported) and add there the database client and the database interface library.
