Thank you for making this, I have been learning Node-red on my own and this is helpful.
Happy to hear that :)
I have been SEARCHING for so damn long. I wanted to take one output from a function and then send it to another function. I couldnt find any tutorials and the guides online were not being clear on the syntax to do it. But I finally saw an example of this in your video. Thank you Rajvir!
Now I see that you just need to keep writing "msg.payload" for everything.
I originally thought you had to refer to the other function like:
"msg.payload.OtherFunction.Variable" or something. I guess not...tho its kinda weird we dont do it that way.
Glad to hear that my video could help you :) You can also define an object in your function lets say object named apple and then you can return apple.payload as well. Msg is a default name of the object if you do not define an object. You can check the course Node-RED made Easy to learn more about it. The course is availale at www.codeandcompile.com
@@thegeterrdone Thank you again. So even when I don't create an object, NodeRed still makes one and its called "msg", and msg is the main way to send data from one block to the next. At least that's how I see it.
I'll check out the course too because I think I need something more structured for me to truly understand why certain things work in NodeRed.
Super easy to follow. Thank you so much.
Thank you for your video. It's helpful for me. It's great.
Thank a lot sir.
Your video is very important for us thank you sir

Hi I am Kamalraju, can you explain "Switch Statements with break keyword" in function node in node red please...!!!????
Hi, This has been explained in my Node-RED courses available on www.codeandcompile.com 😎
hello ....I need to subtract 2 msg.payload entries from a numerical value and obtain 1 output ... could you help me ... I don't know how to designate each msg.payload if they are identical enter the same name
Hi, one way is that you store the value of msg.payload into the flow or global variable and then you can do the subtraction.
Great video . i need help please can you help me how to do data classification for diagnosis of patients using red nod ?

Awesome Video Man. Helped Me A Lot.....Thank You
Thank you for the explanations. Pls, do you want to help in showing how to connect the installed modules (such as npm i fhir, or npm i uuid) in node-red?
This is because, if you pass " var Fhir = require('fhir').Fhir; " in a function node in Node-Red, it'd throw an error. Even after configuring settings.js as specified in node-red.
I do not get your question. Can you write me at compiletocode@gmail.com
sir full node red tutorial playlist ?
Check full NodeRED course here: www.codeandcompile.com
Thank you .Can l conect paithon classification to red node
What do you want to connect specifically?

Good evening Ranveer I require one help from you. I have a Delta HMI of DOP-B07S411. In my plant I need mirror the HMI display on my laptop. I saw the e-remote server from Delta . But the manual says it requires a Ethernet enabled HMI. Is there any other way we can do it.
That is right, you need Ethernet enabled HMI to get the screen on your computer. There is no other way for Delta HMI without Ethernet. But if you just want to monitor few parameters from PLC, you can actually use Node-red and build you own dashboard for monitoring and control
Rajvir Singh Thanks a lot Ranvir.
@@SDEB50 its Rajvir ;)
Rajvir Singh I am so sorry Rajvir Ji . Actually during the lockdown I learned about PLC programming from you . I would take this opportunity to thank you for that as well.
@@SDEB50 you are welcome ;) I am happy that you learned PLC :) ..node red is the next big thing now :)
