OPC UA in Python
This Tutorial will use the OPC UA protocol to send data between different devices or different programs. OPC UA is a communication protocol. OPC UA is mainly used for industrial purposes (industrial automation), and it is one of the most used protocols in the industry today.
There exists lots of different OPC packages and libraries for Python. This Tutorial will demonstrate OPC UA in Python with some basic Code Examples using the “opcua” Python package. This Tutorial will use the Thonny Python Editor and the Spyder Python Editor, but other Python Editors can of course also be used. This Tutorial will use the OPC UA Server Simulator from Integration Objects (free OPC UA server for Test and Demonstration purposes), but other OPC UA Servers can of course also be used.
We will create both OPC UA Clients and an OPC UA Server using Python and the “opcua” Python package.

Hello Sir, My Raspberry pi 3 is connecting to Labview and working I2C also connected and tested with ADS1115 module but when i am trying to MCP2515 SPI to CAN SPI communication not happening and also UART showing error like UART(0) not available & for SPI raspberrypi discinnecting but tested with raspberry pi board manually it os working fine. Raspberry pi:2019 raspbian buster OS LabView: 2020 Community edition If you help me it will support to my technical growth and also I able to do a lot of project with this. Thank you. Naga pavansai Kancharla.
Hi sir, Im begening learn labview. Can you teach me how to creat 1 combobox, the value load from 1 column on the SQL data base ?
great videa ty very much, however you should included the filler script for filling up the database with some samples
Under what circumstances should we opt for a discrete model and controller instead of a continuous one? Nice video, thanks.
Thanks for a great video! I have a question: is it possible to, in the same program, use the I2C communication and use the "normal" digital write/read with serial? I'm trying to control a DAC with I2C and at the same time control the other I/O pins with serial digital write/read.
Hello ! Books_Tables_Script.sql file ? Where to find ?
Do you have any video on creating ScottPlot chart using Excel Data Sets
Expertly paced for beginners and professionally presented. Awesome little guide to talking to Arduino via LabVIEW!
تحية طيبة شرح ممتاز. ارجو تفعيل ميزة الترجمة لو سمحت
Thgank you Sir!
At 11:49 you are hiding the main form then at 14:22 you are creating a new instance of the main form. Is that why closing the main app at 16:44 it stays running? wouldn't it make more sense to pass the main form to form 4, then on form 4 create a new instance and set it to the original instance for the main form? That way you only have one instance of the main form in memory, also then when you close the main form it stops it in visual studio. - nevermind that also creates a memory leak... so would the best way to handle that be to use events to trigger the show / hide of the main form?
Thanks for your excelents explanations it is quiet rare to find someone so methodic and clear!!
thank you for your sharing
Why didn't you talk about the Firewall warning. Seems important.
You have proven that an old dog like me can be taught new tricks, Thank You Sir,
Thank you Sir, this helped alot.
great explanation and very useful for my work. thank you sir
Can you please do a video on how to parse the data from thingspeak please
Hi, It is shown in this video and in the resources you find in the Description field below the video. LabVIEW examples are shown in the video but code details can be found in the Description field below the video.
can u explain why is start address 1 in code but in the software it is 0?
Thank You for all your DAQ videos.
What if I go beyond 5 Volt and below 0 V?? Will it harm the DAQ device?
Yes it can probably harm your device, so it is important to check using a multimeter or something
Hello Sir, I am trying to interface Raspberry Pi 4 with LV 2020 Community edition, but not able to do so. Always at LV side error as not able to connect to target. Can you share the Raspberry Pi OS which you used and successfully interface as described here. Please share link to download Raspberry Pi OS
There is only one place you can download the Raspberry Pi OS image, see the Description field for the video and the information there.
Thank you for this. However, in the future, I would ask that you go through each step from start to finish. I have never used a DAQ device and it would have been beneficial to see each step through the process.
Thank You very much for such wonderful and educative videos
Hello, I have few questions: 1. My thermistor shows 6 degrees more in the room. Is it Ok to just deduct 6 from final value? Or with increaing temparute , it will be not correct? I'm planning to use it up to 100' с. 2. Have hard time with 100k thermistor. I use also 100k resistor and put in code Ro= 100 000. But final result is 65. It's 42'c more than expected. Any advice here? Thanks in advance!
Tried to play with Ro(increasing it) and tried to use static parameter to deduct value. Both options doesnt work. With increasing temperature real gap in value of temperature is also increasing( I use separate thermometer as reference, which shows accurate value).
Thermistor itself should work fine ( I took it from working thermometer, which I use as reference - I have more thn one). So might be some issue with formula or my schema itself. Would appreciate any advice.
Ok even with 10k thermistor - value is not consistent. Not sure how ppl can rely on it. Will try DS18B20 - maybe will be more lucky with it
First of all, thank you for your video, second I have a question. Is that possible to read a file from cloud and show the data remotly (on the web or something like that)?
Im connecting without problem with UAExpert, but with labview Toolkit I get an -356698 error (Unable to locate the host), but the address is the same... Any suggestions?
Thanks for your effort. I had learn many tip and design flow from this tutorial.
Thx so much
Many thanks for your videos😀😁
Thank you for this excellent and professional content.
Thank you a lot. The best Tutorial series. I do not need to attend any course. Just following you, doing the same what you do.
Thank You so much for all such LABView Videos
you should make a course on udemy or somewhere
love this channel... thanks!
Very well explained. Thank you !
Thanks for your wonderful effort

Hi Mr. Halvorsen, Thank you for such an informative video. Could you also create a tutorial showing how to transmit the logged data to a cloud server? Perhaps over Wifi or cellular? This would be ideal for mobile (in motion) systems.

Hi Halvorsen, can I use WinForm to create a search bar connecting to database and find each item by typing is name or id and view it in the form window?
Hi, Yes that should be possible. I guess it is only your imagination and your skills that that sets the limit of what's possible to make.
Good day i want to understand how can i implent methamatical model in python field multi objective optimization of integrated energy system
Amaaaazing ! it helped me a lot, thank you !
Thanks! This was a great refresher as I need to debug some Labview code and it's been at least 5-6 years since I touched Labview in University.
v good explanation to understand class. sir was able to place c2f() and f2c() function in class , since its small functions. what if the function is big enough??
Large functions should be no problem. The limit is the built-in memory on the different Arduino devices.
Thanks - very clear in your explanations.
What about SSL/TLS?
Then HTTPS should be used
@@IndustrialITandAutomation where to install Certificate on our code?
The TLS certificate is normally on the server-side, in this case the ThingSpeak service. So basically use HTTPS instead of HTTP in your ThingSpeak API URL. Then the rest is taken care of by the server and the Python libraries used.
@@IndustrialITandAutomation Ok thanks
Thanks to sharing this tutorial. It was useful. If Raspberry pi has a display can we see labview front panel to control the application?
