DAQmx, specify resource occpaied

I am using a below function to get the digital port status of DAQ card.
DAQmxErrChk(DAQmxReadDigitalU32 (Handle, 1, 10.0, DAQmx_Val_GroupByChannel, &SSR, 1, &read, NULL));
whole code as below:
error = Init_DA_Brds (1, &BoardCode);
DAQmxErrChk(DAQmxResetDevice ("DAQmxDev1"));
DAQmxErrChk(DAQmxCreateTask ("", &Handle));
DAQmxErrChk(DAQmxCreateDIChan (Handle, "DAQmxDev1/port0/line6", "", DAQmx_Val_ChanForAllLines));
DAQmxErrChk(DAQmxReadDigitalU32 (Handle, 1, 10.0, DAQmx_Val_GroupByChannel, &SSR, 1, &read, NULL));
DAQmxErrChk(DAQmxClearTask (Handle));
however, some of times i get error that DAQ resource has been occpaid. later on , if i try to reset in Max, also a error report, whatever i reset the driver in traditional DAQ according to instruction.
do someone know this problem ?
( i am using CVI 7.1+ DAQmx 9.0.2)

Hi, Muks
Firsty, thanks very much for you attention.
however, i am not sure i understand you question correctly. this problem was not occured at first time of program running. and once this happend , the only way to solve is restarting the computer .

Daqmx error num: -50103 with message: The specified resource is reserved. The operation could not be completed as specified.

Hi, I am running a program where I have 4 nidaq cards on a single machine, all connected. I am trying to start a counter and keep getting that error (daqmx error num: -50103 with message: The specified resource is reserved. The operation could not be completed as specified.) in two places in my code. I understand what the error means (you can only have one task of a type per card), but I don't see where that is occuring in my code.
See below for code. I noted the two places where the error is occuring. I am debugging someone else's code, which is part of the problem.

Error 50103 the specified resource is reserved - task name - on 4 modules

Hi all.
I'm sorry i put this post by mistake in Measurement Studio for.NET: smileyindifferent:
Let me tell you my configuration:
software:   Windows XP sp3, Labview 8.5 en.
hardware:   NI-cDAQ chassis 9172 with 4 modules installed (in this order):
                        1. NI-9217 (4 RTDs)
                        2. NI-9217 (4 RTDs)
                        3. NI-9219 (4 RTDs)
                        4. NI-9219 (4 RTDs)
So, i want to aquire 16 temperatures.
In MAX v4.3, all is working fine.
As you aspected, I have the famous error 50103: "The specified resource is reserved. The operation could not be completed
as specified". "Task name: unnamedTask<9>".   - highlighting module #2.
My goal is to read these temperatures consecutively, i mean: mod1 ch0..ch3, mod2 ch0..ch3 and so on.
My programm (vi) is like that:
In a while loop I have a Stacked Sequence Structure which has 4 frames, each for every DAQ Assistant asigned and configurated
for those modules.
So i have: Assitant1 for mod1, Assistant2 for mod2, and so on.
The Assistants work well in configuration preview mod. (I see 4 temperatures on each module).
But in my programm, i got the error above, on module2.
I read something about this error and I understand that I can't use 2 or more resource in the same time.
I understand that a resource represents a channel on a module.
At each DAQ Assistant output I have a Split Signal (split in 4)
But with this configuration and this algorithm I suppose I read all 16 channels in total consecutively, not in the same time.
Am I wrong ?
How can I fix the problem ? : smileysad:
Thanks.
Solved!

Hi dsasorin,
The error that you have mentioned can be caused due to a number of reasons. There is a knowledgebase article listing several reasons for it that can be helpful. Have you created a task beforehand in MAX? Are you generating the code directly from it or are you writing the code in LabVIEW and asking it to use the channels from the task you specify? Have you tried using the lower level DAQmx VIs such as DAQmx Task name and then tried generating code from that by right-clicking and selecting Generate Code >> Configuration and Example. Hope this helps!

One or more of the specified resources could not be re-assigned. This can happen if the proposed resource to be assigned has already an assignment on the given task or the specified assignment is deleted or rejected.

I create a brand new plan based on a template.
A task in that plan has a team resource assigned. the task is fixed work. The PM may change the work and duration but not the team resource.
The plan is published.
I delegate my self as a team resource: and try add myself to team task in the timesheet area (using insert row). I can choose some tasks and the add. Most tasks throw this error. This happens if nothing on the plan is changed - it is brand new - minutes
old
One or more of the specified resources could not be re-assigned. This can happen if the proposed resource to be assigned has already an assignment on the given task or the specified assignment is deleted or rejected.

Trying to stop the swap to Salesforce - but the errors keep a coming

oooch - I can fix it - I need delete the task and recreate it. Which is amazingly tedious as I cannot see if a task needs recreating or not. There's 10 template plans and an average of 200 tasks - then I have to rename the template - the assign the
new template to the EPT - this will be a long night; with only complaints at the end.

Azure Rest API PUT Block Blob Returns "The specified resource does not exist" CORS

I am trying to upload a file to Azure Blob storage. For some reason when I try to put a new block blob on in the storage it tells me the resource does not exist. I am sure it is something silly I am missing.
According to the documentation:
The Put Blob operation creates a new block blob or page blob, or updates the content of an existing block blob. Updating an existing block blob overwrites any existing metadata on the blob. Partial updates are not supported with Put Blob; the content of the
existing blob is overwritten with the content of the new blob. To perform a partial update of the content of a block blob, use the Put Block List (REST API) operation.
CORS is setup and that seems okay.
When I do a preflight and get this:

How to handle "The specified resource does not exist" exception while using entity group transactions to purge WADLogs table

Hi,
We have a requirement to purge the Azure WADLogs table on a periodic basis. We are achieving this by using Entity group transactions to delete the
records older than 15 days. The logic is like this.
bool recordDoesNotExistExceptionOccured = false;
CloudTable wadLogsTable = tableClient.GetTableReference(WADLogsTableName);
partitionKey = "0" + DateTime.UtcNow.AddDays(noOfDays).Ticks;
TableQuery<WadLogsEntity> buildQuery = new TableQuery<WadLogsEntity>().Where(
TableQuery.GenerateFilterCondition("PartitionKey",
QueryComparisons.LessThanOrEqual, partitionKey));
while (!recordDoesNotExistExceptionOccured)
IEnumerable<WadLogsEntity> result = wadLogsTable.ExecuteQuery(buildQuery).Take(1000);
//// Batch entity delete.
if (result != null && result.Count() > 0)
Dictionary<string, TableBatchOperation> batches = new Dictionary<string, TableBatchOperation>();
foreach (var entity in result)
TableOperation tableOperation = TableOperation.Delete(entity);
if (!batches.ContainsKey(entity.PartitionKey))
batches.Add(entity.PartitionKey, new TableBatchOperation());
// A Batch Operation allows a maximum 100 entities in the batch which must share the same PartitionKey.
if (batches[entity.PartitionKey].Count < 100)
batches[entity.PartitionKey].Add(tableOperation);
// Execute batches.
foreach (var batch in batches.Values)
try
await wadLogsTable.ExecuteBatchAsync(batch);
catch (Exception exception)
// Log exception here.
// Set flag.
if (exception.Message.Contains(ResourceDoesNotExist))
recordDoesNotExistExceptionOccured = true;
break;
else
break;
My questions are:
Is this an efficient way to purge the WADLogs table? If not, what can make this better?
Is this the correct way to handle the "Specified resource does not exist exception"? If not, how can I make this better?
Would this logic fail in any particular case?
How would this approach change if this code is in a worker which has multiple instances deployed?
I have come up with this code by referencing the solution given
here by Keith Murray.

Hi Nikhil,
Thanks for your posting!
I tested your and Keith's code on my side, every thing worked fine. And when result is null or "result.count()<0", the While() loop is break. I found you code had some logic to handle the error "ResourceDoesNotExist" .
It seems that the code worked fine. If you always occurred this error, I suggest you could debug your code and find which line of code throw the exception.
>> Is this an efficient way to purge the WADLogs table? If not, what can make this better?
Base on my experience, we could use code (like the above logic code) and using the third party tool to delete the entities manually. In my opinion, I think the code is every efficient, it could be auto-run and save our workload.
>>Is this the correct way to handle the "Specified resource does not exist exception"? If not, how can I make this better?
In you code, you used the "recordDoesNotExistExceptionOccured " as a flag to check whether the entity is null. It is a good choice. I had tried to deleted the log table entities, but I used the flag to check the result number.
For example, I planed the query result count is 100, if the number is lower than 100, I will set the flag as false, and break the while loop.
>>Would this logic fail in any particular case?
I think it shouldn't fail. But if the result is "0", your while loop will always run. It will never stop. I think you could add "recordDoesNotExistExceptionOccured
= true;" into your "else" block.
>>How would this approach change if this code is in a worker which has multiple instances deployed?
You don't change anything expect the "else" block. It would work fine on the worker role.
If any question about this issue, please let me know free.

"The specified resource is reserved" in DAQ error

Dear all,
Earlier before I posted a thread on "stop error caused by device driver?". The problem was partially solved, however, new problems start to come up.
Basically the problem is that I have an PXI-6115 DAQ card, I used its two output channels to control my scan mirrors (by send two sawtooth waveform out). Everytime I finished one scan cycle, I need to put the mirror back to its originial position by using the same two output channels (sending two single voltage out). Since these two tasks are of different type, I created two different tasks: scanTask and parkTask. Then I do the following as suggeted by TheWoost:
1. create and configure task handles for scanTask
2. create and configure task handles for parkTask
3. start scanTask and stop after finished one scan cycle
4. start parkTask and stop after returning to orginial position
Then repeat 3 and 4. The problem comes in when I get to step 4: "Function DAQmxStartTask: (return value == -50103 [0xffff3c49]). The specified resource is reserved. The operation could not be completed as specified. Task Name: _unnamedTask<1> Status Code: -50103"
I browsed through the knowledge base and realized that I cannot have two tasks using the same output channel, even though only one of them is active. If I clear scanTask after stopping it, then recreate it when I need it, that would be fine. However, that would be too much trouble. I was wondering if my understanding is right. If yes, is there anyway to get around it? I need to run scanTask and parkTask in a loop and it would be hard to recreate the task everytime.
Any input is highly appreciated. Thank you for your time.
Best Regards,
Dan

Dear Rob,
Thank you for offering your expertise on this problem. I would be happy to include my code here. Right now I take the alternative approach by clearing each task after it's finished and then recreate them. It works fine but brings in complexity and inconvenience. If you can get away with this, that would be great.
The code is an except from the whole program. Since I changed it back and forth so many times, there might be some errors. The main part is focusButton and stopButton. When I hit focusButton, the two mirror outputTask are running. When I hit stopButton, I stop these tasks and call parkLaser function, which assign the outputTask to do single point output. Then I can do focus again. This is the part that gives problem.
If there is anything that is unclear, please let me know.
Best,
Dan

You can do it one of two ways:
1. Change the rule of the top level to deny everything.
or
2. Add a rule below your "map C to Z" to deny everything.
The way it works is that when SGD finds a local drive, it'll try find a matching rule. If it doesn't find it, it'll go up the datastore structure and check for rules. And the first rule that applies, it'll use that rule. So, in your case, when SGD sees drive A (for example), it looks at the rule of the person (or profile) object and it does not find a matching rule since you only have one rule (map C to Z), so it goes up the datastore structure, and try finding a matching rule. Since you have no other rules in between, it goes all the way to the top and try to map drive A to "U" (default first drive letter).
Hope this helps.

Error -50103 the specified resource is reserved

I installed DAQ 8.0, and loaded the example AcqIntClk and ir ran with a simulated device PCIMIO16XE10. Then I ran a measurement studio example in which I had to create a task using MAX. That ran okay. Then I deleted the task I had created, and returned to AcqIntClk and ran it again. This time I get the error when I press Start

Specifying resources for DownloadService

Hi
According to the javadocs for the DownloadService, the loadResource() method -> Downloads the given resource, if the resource is mentioned in the JNLP file for the application. This method will block until the download is completed or an exception occurs.
What does it mean if the reource is mentioned in the jnlp file for the application? I want to download a jar from a different web based application and have that jar be part of my application (ie: plugin a special feature based on some condition). For example, here is a code snippet for both my jnlp file and some code used to load some jar in an app from a context root of foo.
From an app with a context root of abc.
jnlp:
<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" codebase="http://<ip>:<port>/abc"
href="launch.jnlp">
<information>
<title>abc title</title>
<vendor>Me</vendor>
<description>This is a description of the something</description>
</information>
<resources>
<j2se version="1.2+"/>
<jar href="abc.jar"/>
</resources>
<application-desc main-class="com.abc"></application-desc>
</jnlp>
Now, my code snippet refers to another jar (not listed in the resources of the above jnlp). The jar might even be on another server.
try
// determine if a particular resource is cached
URL url = new URL("http://<ip:port>/foo/Bar.jar");
boolean cached = ds.isResourceCached(url, null);
// remove the resource from the cache
if (cached) {
ds.removeResource(url, null);
// reload the resource into the cache
DownloadServiceListener dsl = ds.getDefaultProgressWindow();
ds.loadResource(url, null, dsl);
catch (Exception e)
e.printStackTrace();
This appears to fail (ie: jar is not actually loaded via the service, but the download progress window does appear). If I need to list the resource in my jnlp, how can i do so in such a way that the jar can be physically downloaded from an alternate location?
Thanks in advance.

Hi
As a followup, 2 more questions along the same lines...
1) the jnlp file. When specifying the codebase attribute. Does that have to be an absolute address. Or can it be relative.
<jnlp spec="1.0+" codebase="http://<ip[:port]>/abc" href="launch.jnlp">
where, [:port] is optional.
or
<jnlp spec="1.0+" codebase="/abc" href="launch.jnlp">
I receive an error from JWS if using the second one.
2) Is there a way to get around from specifying the additional resources (via the resources tag) that a given application may require so that the DownloadService will be able to locate them? I specified the exact URL given in my code within my jnlp file and it did find the reource for download... but I want to drive the additional resources from a configuration standpoint so as to have a plugable application. Once the application is deployed to my application server I want to minimize my downtime (as people would have to explode my ear/war to modify the jnlp file for additional resources) in regards to installing new applications.
Many thanks in advance.

Error: the specified resource is reserved.

Hi all,
I have composed a program that is going to read 4 analog input voltages, however, I get error as shown in the picture. Basically, Dev1/ai0 thru Dev1/ai3 will be used to get data from. But everytime I run this program, one of the DAQmx reads will light up and the error message will pop up and I am in trouble.
Is there any way I can fix this problem, so that I can read all 4 AIs at the same time?
Thanks a lot in advance.

I guess you did not try to search for this error. It's been asked numerous times.
The answer is simple - don't use 4 separate tasks. Use a single task with multiple channels.

Specifying resources in WCAP command "storeevents.wcap" doesn't work

Hi all. I tried to add an event with a WCAP command like this :
http://calendarserver/storeevents.wcap?id=XXXX&calid=XXXX&dtstart=XXXX&dtend=XXXX&summary=XXXX&resources=RESOURCE_CALID&fmt-out=text/xml
The event is stored correctly but not the resource i want associate to it. I also tried "inviting" the ressource as an attendee (&attendees=RESOURCE_CALID) but i want the RSVP set to true, so this doesn't work for me either.
