Datalog File - error 116

Attached is a program I wrote that reads vibration signals, displays their respective graphs, and then writes that graph to a datalog file. However, every now and then I get the Error 116 message, and cannot figure out why. The best way to replicate the problem is to run the program, enter some text in the boxes, and save that file. Then repeat the process so you have 2 datalog files to read. Then open the "Data Reader" VI and open data file #1. Close the entire program, and open data file #2. Repeat this process until the Error 116 appears. Any suggestions? Even when the error occurs, the information is still displayed, but I need to get the bug fixed.

Jeff, in this post, someone was experiencing the same error message and it was resolved after upgrading to LV 8.0.1. Could you see if installing that patch and mass compiling resolves anything?

Write-read binary file Error 116

Hi all,
I am saving double, numeric array data into a binary file and then trying to read it back but keep on getting Error 116 (cannot read from binary file).
I have attached screenshots of the way I am writing my data into the binary file and then the way I am trying to read it. Basically my data is chunks of 2D double arrays, coming at a rate of 1hz and this is why I have to use the get and set file size functions prior to saving into the file (i.e. so that each time I can append my file with new data).
I have tried all combinations for the write to binary and read to binary file functions, thus meaning I have tried little, big and native endian options but I keep getting the same error. Also played with the way I append my data, i.e. I have used both the "offset in bytes" and "end of file" options, just in case this made any difference, but again no luck.
Any help would be much much appreciated.
Regards,
Harry

Just as an amendment to my original post, I can succesfully read my data in MATLAB using the standard fread function with double precision. I presume that this means that there is nothing wrong with the way I write the data into the file. However, it would be useful for me to be able to read it directly from Labview without having to build matlab executables etc etc...
cheers again

Opening my datalog file errors out with error 42 generic error

I'm using the datalog API to store video images flattened to string (the record type is string). This works great most of the time, and gives me easy access the whichever frame I currently want. My files are between 15 and 125 MB. Occassionally when I try to open a file, the Open/Create/Replace Datalog primitive returns error 42, which is a generic LabVIEW error. The file appears to be the right size and looks as correct as I can tell in a hex editor. I'm guessing it's some sort of parsing error, but I don't know the datalog API binary format. I'd really like to recover these files that are throwing the errors. Any ideas?

Greetings FlamingYawn!
I apologize for the trouble you're having opening some of your saved datalog files. Unfortunately, as you have already mentioned, Error 42 is a general error and as such, provides us with little information that we can use in troubleshooting the issue. From all the research I have done, it seems that the two most common causes of this type of problem are from a logic error in the writing section of the code or from the files being corrupted by some other means during the write (i.e., from bad sectors on a hard disk). Unfortunately, the file type is a proprietary binary format and the structure is not publicly known. We currently do not have any tools for use in reading these files outside of LabVIEW. This is not necessarily to prevent the files from being read by other software but simply because it is a file type that was designed specifically for LabVIEW. The best information I can provide you with is related to the file header. This can be found in the following KnowledgeBase article:
LabVIEW Data Logger: Binary Header File Format
http://digital.ni.com/public.nsf/allkb/747B83B6C8E4A6218625669100563B61
If it is at all possible, please try to see if the same set of data produces the same error each time following the write/read sequence. If this is in fact the case, I can work with you further to file a Corrective Action Request so that the developers can address the issue.
I hope this helps some.

"Error 1 when trying to open and read datalog file from several subVi's

So, I've been coding up this model based controller and have hit a snag:
The program starts and opens a datalog file and passes the refnum to two loops.
At a regular time interval (every 2 minutes), one loop (that's iterating once per second) writes the current information to a datalog file.
Meanwhile, another loop (that's iterating continuously) checks to see if the file is big enough to support training of the model, if it is, then the training process begins. Once this happens a period of recent information is read from the file. Initially, this read would fail and return 0 data. However, this problem was fixed by passing in the data file path rather then the refnum and having the vi open,
read, and close the data file. With the path, the vi was able to read all the data. However, still in the same loop, another vi downstream tries to read the file and returns error code 1, and no data is read. I tried passing that vi the path and seeing if it made any difference to open, read and close the file. But even then the read failed (with error code 1).
I don't understand why it can read in one vi and not the other!
Does anyone know what is going on here? It seems that semaphores would probably solve the problem, but would prefer a simpler solution. Thank you very much.

Try passing the data to the continuous loop through a LV2-style global. That way you are only access the file in one place. But then that begs the question, if the data is passed internally, do you really need the file at all?

How Do I Convert LV7.1 Datalog Files to LV8 Format?

I have several LabVIEW 7.1 datalog files that generate Error 71 (File data type conflict) when I try to open them in LabVIEW 8 using the new Open/Create/Replace Datalog vi with my original typedef constants wired to the record type terminal. Likewise, my original LV7.1 code recompiled in LV8 often generates error 116 (unflatten or byte stream read operation failed due to corrupt, unexpected, or truncated data) or error 4 (end of file encountered) when randomly accessing records in the LV7 datalog files, presumably due to changes made to the datalog file structure in LV8. I recall one time when a dialog box popped up asking if I would like to convert the file to LV8 format. Since this was a file currently in use on the server by LV7.1 clients, I had to reply no. With copies of the datalog files now on my hard drive ready for conversion, I haven't seen the conversion dialog box pop up again.
How do I convert the LV7.1 datalog files to LV8 format?
Thanks,
Larry

Good afternoon Larry,
Thanks for posting!
The Datalog file support in LabVIEW has changed, but the underlying
principles of the technology remains the same.
Converting to the new format should just involve converting a few VIs to the new Datalog-specific versions. As you can see, the new Datalog VIs appear in
their own sub palette in 8 which will help keep things simple.
Before we address the concerns with the errors, let’s first
make sure that the code has been properly converted.
To convert your VI to the new format:
1)      Replace
the Open File VI from LabVIEW 7 with an “Open/Create/Replace Datalog” VI in LabVIEW
8. Keep your type constant or control
wired to the “Datalog Type” input.
2)      Replace
any “Write File” VIs in LabVIEW 7 with “Write
Datalog” and triple check that your data matches the datatype wired into the
open exactly.
3)      Replace
any “Seek” VIs with “Set Datalog Position”. The input to this VI is the number of records
to advance (check the mode set by the “from” parameter).
4)      Replace
any Reading VIs with the corresponding “Read Datalog” VI.
I suspect that if you are receiving errors saying that the
end of file has been encountered it is a result of a bad input to the “set Datalog
position” VI. I attached a basic example
of writing a Datalog file in LabVIEW 8, and reading the results. The rest of the functions in the new Datalog palette
should be pretty straightforward.
Does this help? I
would be more than happy to answer any other questions on this if you need any
additional clarification, or if this response does not address your question.

All that you need to do is right-click on the Read from Text File and Write to Text File functions and uncheck "Convert EOL".
Other comments:
You should not hard-code the path inside the VI. Either place a front panel control to specify the path (perhaps with a default value set), or generate the path so that it is relative to the VI (such as being in the same directory as the VI).
You are not wiring all your errors through so some errors can be lost.
You do not need to have the VI open a reference to itself. If you delete the Open VI Reference function the code will still work.

Same data wire (source and sink are listed as "datalog file reference of") will not connect

I am trying to write a short program that will convert a string spreadsheet file into a datalog file with the numbers turned back into numbers. I have a case structure for each type of spreadsheet (different types per columns and different number of columns). I use a 'for loop' to process all records (rows). And I use a 'sequence structure' to individually process each column item into its original format (string or number), then group together into a bundle and then write the results to the datalog file format.
The first two (case structures) worked but the second pair of case structures would not allow me to connect the datalog file reference number from the 'write to datalog file' to the 'close datalog file' through the 'for loop' wall.
I am using 8.2
I am sure it is an stupid issue, but the error message just did not point me towards a solution.

PROCESS SH TO DLOG.vi ‏84 KB

The problem is that you are creating a different type of datalog file in cases 2 and 3 than you are in cases 0 and 1.
The structure of a datalog file is the same as an array of clusters. All of the clusters must be of the same structure. Only the values of the individual cluster elements can vary.
You are trying to write three different cluster structures to a single datalog file. You just can't this.
You'll either need to write to three different files, or come up with a structure that everything will fit into.
One other quick hint. NEVER use a variable to pass data when you can wire the terminal directly to the function.

Error 116 & Warning 10694

Hello colleagues,
I know that the "error #116" issue has been discussed a lot lately, but none of the posts helps me cmprehend the source of my problem described below, epecially given that my concept had worked well with previous versions of LV.
I use "Sync=4472 Trig=6713.vi' to synhcronize 72x AI (9x PXI-4472) with 2xAO (PXI-6713) on a shaking table. This VI successfuly saves sequences of 3D array in a binary file. The parrent demo VI is "write.vi" which performes the DAQ and streaming to disk. No porblem here, except for the warning #10694 which I also do not understand where it originates from. The missing VI is a 2D array constant containing 10 minutes of signal generatuion sampled by 1000 S/s - I just subset the length I need according the acquisition duration.
The error #116 is reported by the "Read from Binary File.vi" in the demo "read.vi". I do not see what causes this error since the data type definition I wire to the "Read from Binary File.vi" is the same 3D array of doubles!?!
Can somebody "116" experienced take a look at the this simple and clear demo and possible identify my mistake?
Thanks in advance

Hi again and thank you for your time. Uploaded are couple of files, both containing sampled data of 1 second at 1000 S/s. The only difference is the chunking which shoud prove correct data streaming to disk - the "10" file uses chunks of 10 samples per channel to read and stream, the "100" file uses chunks of size 100 samples per channel.
The files are not of TXT format! I had to put that extension for this forum to accept their upload. So you can safely remove the extension.
I use transpose matrix for the chunks (72x10 / 72x100) so upon successful data retreival from the files you should get straight 72x1000 samples (1 second acquisition at 1000 S/s)
Thanks in advance,

Corrupt DataLog file?

Long time someone post something regarding the DataLog files.
You know, File I/O\ Advanced File Functions\ DataLog
Is it because it's "old skool" and there is something better now??
Anyway, allow me to ask this question.
I have several DataLog files, all of them I can read with the existing EXE file and LV development code except one
I always get the error code 71 when reading that specific file.
Since all files are made by one and the same LV EXE file I find that very strange.
I then read several files using note pad to get an idea about what's inside.
All files I can read starts with: DTLG € # ! $ @0ÿÿÿÿ
The one I can't read has the same pattern from character 146 onward.
I have no idea at all where those 145 characters came from ?!!?
"Ç Started-20140508.dat C:\PROGRA~1\BEKAER~1\TIREIM~1\DataBase\STARTE~1.DAT 6 C:\Users\WU71AD~1.SHE\AppData\Local\Temp\STARTE~1.DAT ‘Å
The first readable characters are the name of the file, the following path's, no idea!
After the four ÿ characters I see the correct definitions of the cluster I use in all files, so that is rather good, I suppose.
Easy solution I tried, delete the 145 erroneous characters but then I get error 42 : LabVIEW: Generic error. when reading the new file.
Anyone an idea how to "uncorrput" this file correctly ?
All happens in LV 8.6
Thanks for reading
Even more thanks for a solution!
Best regards
Alain

Error 116

GoodMorning.I have a problem when I try to read data from binary file .An error 116 is appeared.

I am getting the same error now, even though I am quite sure I have the correct data types. To get the data type for the Binary Read vi, I simplyed used 'Create Constant' from the data I had wired in to Binary Write vi. The read and write commands are in separate VIs I have made, as one creates temporary files, and the other recalls the data. I have posted two images of where I Write and Read, any help would be appreciated.

How long is the wedding video?
My standard list of things to do first...
Run MacJanitor (free download) to do all the Unix Cron Maintenance scripts.
Run Disk Utility (Applications -> Utilities) and repair disk permissions on your start up drive (typically your internal drive). Also verify any other drives mounted on the system.
Run Preferential Treatment (free download) to check for corrupt/damaged application and system preference files.
Run Cache Out X (free download) to clear all system and application caches.
Reboot your Mac.
If you still can not get it to run correctly, next thing to try is to throw out the iDVD preference file (don't forget to change back those preferences you want different from the defaults next time you run it). If it still doesn't work, then I would suggest you reinstall iDVD.

Crystal Server 2013: How to troubleshoot "Can not create temp file---- Error code:-2147215357"

We have a Java7 web app, which generate PDF report by calling Crystal Server 2013 SP4.
The app is being deployed on many different servers. We sometimes got the error below when generating report:
com.crystaldecisions.sdk.occa.report.lib.ReportSDKException: Can not create temp file---- Error code:-2147215357 [CRSDK00000615] Error code name:internal

at com.crystaldecisions.sdk.occa.report.application.PrintOutputController.export(PrintOutputController.java:130)
at com.crystaldecisions.sdk.occa.report.application.PrintOutputController.export(PrintOutputController.java:113)
Problem is, this seems to be a pretty generic exception. It could be caused by many different reasons.
e.g. network connection problem, wrong DB login, wrong folder path, lack of folder access right, etc.
Each time we could only guess what's wrong.
We are running into it again, and this time everything seems correctly configured so far.
We wonder if there are more info we can get to troubleshoot? For example, any log file of Crystal Server we should look into? Or does Crystal Server has debug mode which prints more details to tell us what goes wrong?

Hi Henry,

Apply trace on RAS server and check what you find in RAS logs.
Check whether you can see timeout error is RAS logs. Usually if connection is lost and the RAS server no more have the session to write to the temp directory, we do see these errors.
Also, does the account that runs RAS have permissions to create a file in RAS's default temp directory? Are you getting any out of memory or out of disk space exceptions on App server or RAS, tracing RAS server is the way to move forward.

How to configure tracing, and where are RAS logs? Is it configured in CMC --> Servers --> Crystal Report Services?

Pretty sure yes.

Not on App server.
For RAS, that's the problem, I am not sure where to look.......
