I used to use Silverlight with an older version of IE. How do you use a recent browser like EDGE or FireFox to communicate with my 9038 cRIO?

Termotek P310 Chiller Control via RS232
Does anyone have any experience in trying to remotely control a Termotek P310 Chiller via RS232?
I have contacted Termotek and they have sent me a bunch of information (attached).
I made a LabVIEW VI that sends an inquiry to get the chiller temperature setpoint, but I have not had any luck in getting any kind of response back from the chiller.
Any help is greatly appreciated.

UDP Read problem on cRIO
Hi all,
I am using a cRIO 9036 to communicate with a third-party device using UDP to read data and send commands (the device is a SMA Sunny Webbox). The communication is based on a remote procedure call - RPC, and is described here: https://files.sma.de/dl/4253/SWebBoxRPC-eng-BUS112713.pdf
It works fine when I use LabView running on my PC. However, when I run the same VI on the cRIO, no data is received (UDP Read vi) and I end up getting a timeout error. I've tested UDP write and it works fine (cRIO sending commands to the Third party Device is ok!).
The VI is in annex. The cRIO sends a request and the third party device is supposed to answer once the request is received.
To further test any connection issues, I have emmulated a UDP server on my PC to communicate with the CRIO operating standalone, and in this case the cRIO was able to both read and write to the PC. The cRIO, PC and the Third-party device I am trying to communicate with are on the same network. The cRIO is connected to the network via 9036's Ethernet port 1.

Timeout Error while trying to read voltage from 2182A
Hi,
I am using 2400 Keithley sourcemeter to bias a 10 Ohm resistor with +1mA (then -1mA). I want to use the 2182 to read the voltage across the resistor when the 2400 sources this current. On the hardware/physical set up the 2182 reads the correct voltage (9.8 mV).
On the software side, I keep getting a timeout (VISA (Hex 0xBFFF0015) ) error when I run the code.
(this is the part in the code where I config, initialize and start the 2182 buffer VIs. full code file attached.)
I ran the 2182 example VI 'Data buffer store and acquire' for DC voltage reading and it works just fine. So I do not believe there is sth wrong in my timeout settings/termination character.
Pretty new with labview so any guidance at all is appreciated! Am I using too many time delays or not enough? I tried increasing the timeout of my instruments in VISA panel but that does not help.

String controller help with showing English and Chinese without spacing
I'm having issues with unicode in labview with string controllers.
I want to be able to type english and chinese together in a single control and being able to backspace.
ex)
However when I'm using Force Unicode Text, the english letter became represented as UTF16LE and requires me to backspace twice to delete a single letter. If i only delete once, it screws up the whole input.
ex) deleting the space between a and s
I've found that I could use Update Value While Typing with NI Update String in the Value Changed Event
This lets me input/backspace properly, but it also caused more bugs with the font size resizing and becoming double lined when entering long strings.
As well as scrambled overlapped characters and the display remains on the first line eventho multiple lines were entered.
Currently I have set the following
Event: SControl -> Mouse Down
Can anyone help?

Error -2147220324 during base image install on cRIO
Hi everyone
I am trying to install a base image onto a cRIO 9047 over a slow VPN connection. After one minute, the installation process fails with this error:
Error -2147220324 occurred at nisyscfg.lvlib:Install Set.vi:1500001
Possible reason(s):
NI System Configuration: A file transfer error (FTP or WebDAV) occurred.
Local file: c:\program files (x86)\national instruments\rt images\base\17.0\7755\base.tar
Remote file: base.tar
MAX gives the same error. This happens with every base image I try to install. The VPN link works fine and task manager shows an upload speed of 16 MBit/s during the installation.
Since this error consistently occurs after about one minute, I assume this is because of a hard coded timeout.
Is there a way to increase this timeout? Is there another way to "manually" install the base image by e.g. copying it to the cRIO by SCP and installing from command line?

NI-VISA
Hello everyone,
I have trouble accessing my USB port with NI-VISA. I get the same error in my LabView VI as when I try to open the VISA TEst panel from NI MAX. The Error is the following:
Error opening resource:
ASRL1::INSTR
VISA: (Hex 0xBFFF0072) Die Ressource ist zwar gültig, aber VISA kann im Moment nicht darauf zugreifen.
I found various post about this and none could resolve my problem. I have checked if a programm is accessing the port via cmd promt wiht the follwoing command:
netstat -aon | findstr '[port_number]'
and none has been listed. I also tried to rename the port via the device manager. I even complete uninstalled all NI programms and reinstalled them. Nothing seems to help.
Has sombody an Idea what the issue might be?
Thanks for your help.
Cheers,

Triggering multiple GoPro cameras at the same time with LabVIEW
Hi,
does anyone have experience with triggering multiple GoPro cameras at the same time with labview? Specifically, it's about taking different measurements, both visually and via sensors. Since multiple cameras are to record at the same time, it makes sense to have the sensors and cameras both triggered at the same time and in the same development environment. A wired solution would be my preference, either via USB or HDMI. I would also like to avoid disassembling the cameras to trigger them with a signal generator (TTL). This means that the videos are not to be further processed, nor is the data to be stored on the PC direktly. So it would be purely about the synchronous start of both cameras. What I already found out is the usb manufacturer id (vendor id) and the usb model code (product id) via the ni-visa driver wizard. I'm not exactly sure right now if this information is of any use to me and if I can use it as an address to control the cameras. Unfortunately, the suggestions in this forum so far have not helped me. I am very grateful for any advice and would be very happy for any shared solution. Thank you very much for your help and information.

Sending keystrokes to a Excel Workbook via SharePoint
All,
I have an program that sends keystrokes to any open application using the .NET System.Windows.Forms.SendKeys.SendWait method which works great and I haven't had any issues until users wanted to use this functionality within an Excel Workbook that has been placed on SharePoint.
Anyone who has used SharePoint and Excel knows that SharePoint lets you open the workbook within the web browser (I use Edge) and you can interact with cells, add data, etc. I had assumed that using this method would work just like it did before within any workbook using the Excel app but it seems that it doesn't. It acts like the data never gets sent or SharePoint is blocking it somehow.
Has anyone else ever ran into this before? I haven't tried any other browser. The workaround is to open the workbook using Excel. I wondered what others users have experienced, if any. I've attached a sample program to try out.

How to pass multiple values to a callback?
I am learning how to watch a folder for new files. I need to test new files written for certain attributes.
I have the attached example from NI that watches a folder for new files. The example that NI provides retrieves the filename with the base path. I need the entire base path and filename so I can load it in my callback and process it.
The bottom line is I do not understand how the watcher and callback are working together to get the filename.
It looks to me like the watcher "sees" that a new file is saved and calls the callback and passes parameters. From there I am completely confused as to how the two vi's get what data and who passes what to who.
How would I pass a cluster of data to the callback to be used by the callback?

Handeling Control references inside a cluster, change properities of a specific control inder a cluster.
Hi,
Control and Indicators are mentioned as (CI) in this post.
I am working on some UIs and they generally have a minimum of 30 CI, some, I put in tabs (easy to show and hide, just switch to an empty tab), some in cluster and some placed directly on front panel.
I am trying to find a better and scalable solution to handle front panel CI. For this post, I am focusing upon the idea of putting everything inside a cluster and use "Control[]" reference array to further handle each reference as per requirement. Generally, following changes are required in their property:
1) Enter a specific value to CI
2) Reset control to default value
3) Enable & Disable Specific control/indicator
4) Check if all the controls are populated by user, some value other than the default
5) Change color of specific control, if required
Above mentioned tasks are triggered per case/state requirement of the program. So each state would require some changes in properties of a CI.
In the attached VI snippet, Below is what I came up with for the bullet 1,3,4, named as Case1,2,3. I believe same logic can be applied for other bullets.
I was wondering if any one has any suggestions to better handle FP CI.
PS: I store control reference in an FGV at the start of the program for a cleaner diagram and use a subVI that has different hard coded cases triggered by a enum when required.
EDIT: Changed "Under" to " Inside". Update made to subject and body as corrected by @

Why error codes like ERR 5, ERR 5003 and 1073676294 occurring in the interface of LabVIEW with MPU-6050 using LINX (Makers Hub)?
Error codes like ERR 5, ERR 5003, and 1073676294 occurring in the interface of LabVIEW with MPU-6050 using LINX (Makers Hub).
1: Connecting MPU-6050 with Arduino UNO, then from Arduino is connected to PC using a USB cable. Sensor working, the board also working (verified - light blown). Before running the VI, Arduino ON (light blown), L (light blown), TX (light blown), RX (light not blown) are shown in the image.
RX (light not blown)
2: Block diagram created with MPU60X0, LINX showed in the image.
3: Arduino codes are not uploaded to the board. After running the VI, RX (light blown constantly - not blinking, several minutes later not blown, sometimes even in running also) is shown in the image.
4: VI running, but nothing happens, values not coming. After using the Highlight execution button, it shows error codes like ERR 5, ERR 5003, and 1073676294 occurring in the Linx start, MPU60X0 open and MPU60X0 open.
5: This type of error occurs in a random manner. i.e. Firstly ERR 54 coming, next time ERR 5003 coming.

Image from web browser to 2d array
Hello everyone,
I am having trouble converting a black and white image from a web browser into a 2d array to be displayed on a graph. Here is my code and subvi:
The code is supposed to navigate to a web address (which will be a picture taken by a camera in my local network). The code will then take the image data from the web browser and convert it to a 2d array to be displayed on a graph.
I'm not quite sure how to get Labview to convert the image data into data for a 2d array. In the VI I posed you will see a failed attempt at this. If you know how to convert the image data type into a 2d array of values. It would be greatly appreciated.
Thank you in advance!
