Danke für die Hilfe. Ich habe das Problem gelöst. Das Problem scheint kein neues zu sein, ich habe es im NI Forum gefunden, wo es bereits ausführlich diskutiert wurde.
Jedoch war ich auch mit Herrn Blankman und Herrn Brown von Lecroy an der Sache dran. Hier der Schriftverkehr dazu:
Hello Saqib,
The error you are getting is coming from this:
(Embedded image moved to file: pic02582.gif) in the Read Command Error.vi
The "Scan from String" is looking for a decimal value and has some character (could be some text or non-printabel character etc.).

Here, I have setup my input string control to '' Codes Display so I could see spaces and carriage returns.
I get an error because I also have the words "Hello", "Find", "the", and "number" in my input string.
If I remove the printable text and leave the spaces, then I get:

Now, I see that the spaces are still there, but the letters are not. I can get my number from the input string with no errors.
There are a couple of ways to fix this.
If you already know what is causing the error in the input string, you can simply delete it from the string before the Scan.
You can use Scan from String in a loop to go through the string and filter out the number.
To setup the scope for LXI:
On the scope, go to UtilitiesUtilities Setup... from the pulldown menus.
Select the "Remote" tab and in the "Control from" area, select the "LXI (VXI11)" button.

Based on the error you are getting, it looks like you are connecting to the scope.
If you were unable to open the VISA session to the scope, you would see an error like this:

first of all I would like to thank you for your help, I really appreciate that.
I always get the error message:
Error 85 occurred at lcwave Read Command Error.vi
Possible reason(s):
Scan From String (arg 1) in lcwave Read Command Error.vi->lcwave Error Query.vi->lcwave Reset.vi->lcwave Initialize.vi->Untitled 1
The format of the CMR? response is not as expected. Make sure that the Command Header is not being reprogrammed from the value configured in the Default Instrument Setup VI, where it is configured to OFF with the command CHDR OFF. (Default Instrument Setup.VI is called from Initialize.vi.)

Can you send us a screenshot of the error that you are seeing? This doesn't get saved in the attachments you sent me. Also, please confirm that you have the scope set for the LXI connection type since it looks like you are using an LXI connection string. If the scope is set to VICP instead, then you can have problems.
I've CC'd Leonard and Ho on this email... I'll also forward them your attachments.
Best Regards,
Alan

I have the same problem that is described in the forum. I would like to create a VI to control my device via TCP / IP. I have programmed a short Vi, however each time the same error and this results in the following file lcwave Read Command Error.vi occurs. How can I solve this problem. I have in attached my VI, the driver files and the settings in the Automation & Measurement.
I have also installed the Scope Expolrer but without any help.
