hello what display do you use as touch screen?

Hi, I tried to be connected following your steps but my Modbus slave comport is "not running" I wired pin1,2 and pin 3,4 to pins 4 & pin2 of the Slave device in order. Did I connect something wrong or do I need to connect something else? Please help Thank you.

It is not working with me

Thank you!!

Thank you, this has saved me hours of work and gives a good start.

We are lot of subscribers 😊😂❤

Cool

Thank you for the video. I spent several days bugging over the GitHub repository, however, your tutorial solved the problem in a glance. Thank you.

Very useful.

Great Thanks!, Do you know how to use the grfana App installed?, I Start it, but it doesn´n open.

Sir ,can you give me the backup?

Can i get the code for sensor ip?

requesting you to share the code

Sir please make a video on soft motion programming also

weach functions displays an errno when a specific libmodbus functions fails to do its task so i waned to ask whether the string attached to that error is also shown in the output which describes what that errno means? if so how can i add that to the throw in exception handling? thank you.

so good for expanding OOP

Very interesting this contents! I am learning codesys and i have one of this banner barcode reader. I tried to read a qr code with contain 10 Serial numbers, but the chars became swaped inside each word. So I fix it rolling each word 8 bits, and using it after this, with a ok readings of all contents. Will be very didatic if you show the content of the function that converts to a string. Greatings from Brazil!!!

I want to execute a DLL made in cpp using libmodbus inbuilt api's and run that DLL in csharp so is that achievable? If so, then any tips on how I can make that work?

I cant call the function in my ladder. Is the license required to even use the functions?

Good afternoon. Good videos! How to make a PID controller with a discrete output of "more" and "less". Thank you.

Thanks for the video. Please, which modbus simulator did you use? where can I find?

Hi, any idea why on input configuration of the button I don't have the option for mouse click?

from where i can get the hardware used in this tutorial ?

Very useful , hope to see a video using OPC/MQTT using Codesys from you

Great and simple Explanation , just one question , is that guy 9:58 is an Egyptian :D ?

Hi, @chlow1627. Thank you for your videos; they are really helpful. Would you have an alternative way for me to contact you privately for help? I have a small project and need some assistance with it. Thank you.

Is excellent . Thanks dude

I need more videos like that. Thanks for all ¡¡

I'm the 203 subscriber! Thanks for sharing my friend. I love your work! ❤

Great example! Easy to understand and conveyed the points clearly, thank you

Thanks for your tutorial. Where do you set the slave address on 255?

Nice work dude! More codesys videos please!

Can I ask if VisuELems.Visu_PRG has a program in it? I followed you without this part. The results are still communicated, but there is no data transfer between the registers and the Modbus Poll. interface.

Hi. Thanks for the video! If I don't have the modbus license, is there a way to run in demo mode for a few minutes just to confirm that communication is working? I tried all the steps but since I don't have a license, I believe that is the issue I'm having here. :(

Hello, congratulations for the video, it's very good. But, I tried to get the code you posted, but it is no longer available, would it be possible for you to send it to me? It would be of great help in some tests I'm carrying out. Thanks

Great tutorial, could you please share how to extract the only barcode characters without the prefixes ?

do you have tutorial for modbus RTU as slave while controlled by the TCP master using converter?

Great Explanation

Hi, I used your video to write code for connecting modbus mb3000 and I've managed to connect but I get error saying gateway is unavaliable. Do you have an idea on how to fix this problem? I am using vpn connection and only this code to configure the data.

Thank you.

Thanks a lot for the read function. I would like to ask if there is a function to write to registers through MODBUS as well. If so, how to do that? Thank you. Also, is this code only viable for modbus-tcp or can we use it for communication done in modbus rtu as well?

Sir Thank you for your videos. Do you have whats app or any messaging to contact you with. Im a beginner and maybe you could help me with my practice project.

Very nicely presented. Interesting first part, well chosen examples. The second part, with the pumps, a little unconvincing :-)

thank you!

Hello, it's very good, congratulations 😊

Very helpful! Thank you!

Thanks🙏

Your exmples and way of explanation was nice. Can we also connect personally?

I know this is an old video, but i hope you can help. I can't get it to run at 10:34 in the video. It gives me 8 errors of unresolved external symbols. I am running the latest version of Visual Studio Community 2022, that being version 17.5.1 and version 3.1.10 of the libmodbus. I would greatly appreciate it if you have any solution to this and are willing to help.
