The industry is trying to establish unified communication standards for laboratory and bioprocess equipment in the last years, for example LADS and SILA. But these need to be adopted by the market and only the newest hardware will support them Like in any other industry you will always have existing older equipment and manufacturers that implement their own proprietary protocols. So the short answer is: in practice you need to know about all sorts of hardware and protocols... 

I work for a bioreactor manufacturer that needs to comply with a whole zoo of regulations (FDA, GMP, GAMP, iSO 13485 to name a few). Reliability, correctness of data, cyber security etc. etc. become more important day by day. That's why I'm only using OPC UA and the companion standards for all internal and external communications.

My educated guess is that you need to escape the string literals in your query:

STRING_AGG(text_textzeile, ' '||E'\n') AS text_block

Maybe this might help: https://stackoverflow.com/questions/38612364/how-to-increase-the-maximum-amount-of-gdi-object-for-windows-10

Or switching to LabVIEW NXG 🤣, since it is WPF based, which does not use GDI but DirectX directly...

Did you already try this? https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019L3hSAE&l=de-DE

I suggest you google: labview low pass filter

Great job! Guess I need to dust of my Edison as well...

Try registering the assemblies in the GAC (Global Assembly Cache):

Hi,

unfortunately, the class "websocket.lvclass" is missing.

VDB

The VI: File I/O | "File Dialog" allows selection of multiple elements.

VDB

Nice barbie colors...

Right at the start of the VI you compare the password with 'A'. This fails, thus the error message.

VDB

A custom probe using:

Modern | I/O | DAQmx Name Controls | DAQmx Scale Name

should do the trick.

VDB

Defines in C/C++ are replaced by a preprocessor before the code gets compiled.

Why not create a strict typedef ring containing all the values you need?

EDIT: this ofcouse only works when you don't have identical values...

Works fine in a version which is above 8.0, but is not 8.2 (or 8.2.1), so either this was fixed, or it could be an issue with locale settings. You could try setting your OS settings (Control Panel>>Regional and Language Options) to use the period instead of the comma and see if that changes it.

The behavior stays the same, I guess it's a bug..

Is this in 8.0?

I just tried it in versions both before and after 8.0 and I have no problem in typing a comma into a combo box.

Can you upload an example VI with detailed instructions?

It's 8.2. Start LabVIEW, new VI, create a combobox (doesn't matter if modern, classic or system) and try to type a comma.

Pasting a comma works. Maybe it's because of the German Windows...

VDB

One other strange thing I just found out:

It's not possible to enter a comma in a combo box???

Is there a good reason for this??

Hi all,

A few questions regarding the Multi Column Listbox.

First of all: Is it possible to select multiple rows and drag them to another MCL? Every time I try this, only the last selected row is taken. Bug or feature?

I'd like to do the following: move rows around in one MCL to sort the entries, no copying allowed. Furthermore I want to be able to select one or more rows and drag and drop (copy) them to another MCL.

So the first case is moving only, the second copying only. The "Drag Mode" can be set to "Copy or Move", "Copy Only" or "Move Only", but there is no difference made between drag&drop inside a control and outside of a control?

Maybe this can be done using an event structure but I guess that won

Origin is a property op "Pane" now.

You need to customize the color box (Right click, Advanced, Customize, change to customize mode).

Since you can't delete the border, the only option is to make it smaller and hide it beneath the box itself.

Greetings,

Looking at the "PID Integral Action" VI, the output is limited to "output high" / "output low" using the "In range an coerce" function.

So it's more like an 'anti windup hold' instead of a dynamic anti reset windup.

VDB

Hmm, knight in shining armor?

Ok, I just found out that there is currently no way to turn off the tip strips for listbox cells where the column width does not accomodate the cell text. I guess your best workaround would be to make sure the text in the cell does not go past the width of the column.

-D

Thanks Darren,

So if you guys all agree we'll call it a feature instead of a bug...

i'll adapt the width of the column, that's the slightest problem.

Hi all,

i'm using a Multi Column Listbox to display line styles. For example,

I've had great sucess with Port Controller in the past, but never tried it on an RT system...

hmm.. guess .NET and ActiveX will not work on RT... too bad...

Hi all,

is it also possible to directly access the serial port from a DLL without using VISA or Serial?
