Modbus RTU TCP/IP on Node-Red (16bit, 32bit and floating data)

[@khunsun3134]

Thanks for your helpful information. It helps a lot for my modbus project with multiple registers conversion to float.

[@automationcontrolhub]

You are most welcome..

[@rohit026]

This was the video i was looking for. Think you. no any other video like this. keep it up brother.

[@mlu5653]

Really enjoyed following you on your un-scripted tinkering path towards the success! Did I mention it helped me a lot!

[@dariusvaitkus965]

Thank you so much ! Just connected my Beckhoff cx5010 to Node-RED through Modbus TPC in 5 mins when watched this video.

You're welcome, mate.

Hello Geeky-Gizmo-Guffaws, 5.5.2024 calling from Germany. Thank you very much for your Video. I was looking for a long Time to convert/read as a Human the readings from a CINT DTSI666 over Modbus. Now i got it, so many thanks. Sincerly Konrad

[@automationcontrolhub]

you are most wellcome

Sir, how to remove data length error in communication RS 485

[@to1to192]

Hello. I have a qeustion about using this lib. When I disconnect (physically) slave device from hardware where Node-red server runs, whole Node-red server goes down. In console window I see next message: "Error: Writing to COM port (GetOverlappedResult): Operation aborted". To solve this problem I should restart Node-red server. What wrong I do? Any ideas?

[@joseg1864]

Very good video ... But what can we do if we want to write a float 32 bits from node red to a real Modbus server (PLC for example)? How can we save them inside the PLC in two 16-bits registers? Thanks in advance

[@TheKimovitzh]

Worked great for reading iSMA modes TCP modules. No I just need at guide to write to it.

[@beckenbauer1974]

How do i give output from function node to modbus output?

[@ismanma7948]

how to split words into 2 bytes

[@automationcontrolhub]

You can use bit shift operation in javascript, something like: data[0] = (byte) (number & 0xFF); data[1] = (byte) ((number >> 8) & 0xFF);

[@gamamak]

thanks! working. And how will work float32 with +- ?

[@abitrivin2909]

Is't work if data int64 bit?

[@automationcontrolhub]

Yes it can, but it required ieee754 double floating package to convert 64bit modbus data

Hello, I want to set the parameters of an industrial drive using a node through RS485 serial communication. In this project, I need to use the hex codes of an industrial drive and control the drive using the hex codes. Can anyone help me with this project?

[@automationcontrolhub]

Hi, yes you can do it using Hex to decimal pallette on node red.

[@vinistois]

super helpful, thank you

[@vaishakhmonti]

Very good. Keep posting

[@shripadhegde9389]

Super sir, thank you.

[@automationcontrolhub]

Always welcome

[@regenesisiot7466]

Bang .. bisa bikin video untuk node modbus yang serial ?

[@fanystason]

Cool. How about do this in clear python?

[@automationcontrolhub]

I'm really sorry mate, currently i'm working on this stuff only.
