Hi - very basic newbie question

goal is to read-out an energy meter via modbus tcp with node-red and dispaly results in a dahsboard

- energy meter has proper IP-adress and works well with another modbus read-out tool.

I installed node-red (Node-RED version: v3.1.3 Node.js version: v20.10.0) localy on a windows computer and run in firefox using [http://localhost:1880/](http://localhost:1880/)

I added "node-red-contrib-modbus" (v5.27.2), used "modbus-read" and entered all required inputs (ip-adress, register,... same data as I used for the other modbus-tool mentioned above).

After hitting deploy, I see the message "reconnecting after 2000ms" below the modbus-read icon. Unfortunately I don't find any other error-messages or warning...

Can somone please advice, where to start searching systematically? Bellow are the outputs from the cmd-shell. If there other information, which I need to provide, plase let me know.

best regards

Hello Egge and welcome to the forum,

1. Can you share a small Flow to see how you have configured the Modbus nodes ?
2. That other modbus-tool you used, that worked, was it run from the same system as node-red ?  
( share a screenshot of the other modbus-tool's connection settings )
3. Can you `ping` the Energy meter's IP address from the node-red system ?

> I don't find any other error-messages or warning

Try enabling some of the **Optionals** in the Modbus config node to get more detailed status reports

thanks for quick reply...

here is a screenshots regarding your question - more details in next post (since forum-post is limited to 2 screenshots)

yes, other tool was testet on same computer  
ping on energy-meter gives this:

```auto

```

other modbus tool gives this (red circle is value, what I want to read out)

There is the issue

Shouldn't that be **172.20.44.18**

if you are planning to convert to the modbus result to Float values, i recommend the  
[node-red-contrib-buffer-parser](https://flows.nodered.org/node/node-red-contrib-buffer-parser) nodes. Makes the conversion a lot easier.

Dear UnborN,

thanks again... also here you are absolutly right... this was my next challenge... Yesterday I spent hours in trying to read out big endians and convert them to numbers...  
I managed to do it with functions.... probably a lucky punch, since I'm not familar at all with this... at bottom I attached my code, since I can not add \*.json files to this post...  
I also tried node-red-contrib-buffer-parser, but with this I didn't get good results (yet)... probably because I didn't spent enought time with it...

It looks that you are quite experienced with modbus... would you be willing to share some examples or even a complete application to read out modbus, data storage on hard-disk/cloud and visualize it? do you have experience with Janitza UMG 66RM?

cheers

What have you tried ?  
If your register values are **floatbe** you set that as the type in buffer parser.

![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/5/9/5953b1e08744fc18e17ed180ad37b1386f5cf198.png)

The **offset** defines how many bytes to offset from the initial read register 16000  
and since you have enough data in the buffer (because i see you are reading 12 registers)  
you can convert many registers all at once and name them with the convenience of buffer-parser.

( One 32bit float value needs 2 x 16bit registers hence the offset 4 bytes)  
read this post that better explains offset calculations ([link](https://discourse.nodered.org/t/adding-two-values/32784/50))

Regarding storage solutions there are many databases and some very good nodes like sqlite, mysql, mongodb, influxdb. I use sqlite in my project with node-red-node-sqlite. its simple and lightweight.

Hi UnborN,

thanks again... indeed this works perfect! and very easy to collect many data. As you mentioned, it is essential to know, what to read out...

I will continue now "try & error", since now the data are in an object and I still don't know how to manipulate them (e.g. rounding) and/or storing in databse.

For visualization I use node-red-dashboard. With the functions in my previous post, I managed already to have graphical output, however for the object-based output of buffer-parser it looks more complex...

best regards  
egge

You can do the rounding of the value directly in the ui\_text node with something called Angular directives.  
`{{ msg.payload.Voltage_L1_N | number:2 }}`

Here is an example based on the previous flow and also an example Function that prepares an Sql Insert query that can be wired to an mysql or sqlite db. It can be used to insert the data in a Table called **Volts** and as long as you have prepared its Columns to be **dt** for date timestamp, **Voltage\_L1\_N, Voltage\_L2\_N, Voltage\_L3\_N** for the respective modbus values.
