Support/Advice

Feature

  • ( ) feature request

What is the motivation / use case for changing the behavior?

Simple question to get some hint

  • ( ) simple question => please visit the Wiki, the YouTube tutorials and the Info tab by clicking on the node inside Node-RED before
  • ( ) help wanted => you read all information and watched relevant YouTube tutorials, but you need more help

Problem

  • (x) bug report => please search github for a similar issue or PR and test Modbus problems with the modbus-serial package before submitting
  • ( ) unexpected behavior => please visit the Wiki before

Current behavior
I have looked at the CODESYS-CSV-To-IO example. It has some errors in the "filter named register" function (I changed the example documentation Wiki to include a few changes to the code) I'm able now to generate the sdm630.json file but in another folder than in the example (I'm running a docker image). This is where I get stuck. How does Modbus read refer to this JSON file. There is no documentation and the example code doesn't work. Can you give me a few hints on how to proceed?

Expected behavior
I expected a working example on how to map Modbus IO to named IO's

Minimal reproduction of the problem with instructions

  1. Download the Codesys-CSV-To-IO example
  2. Apply the code changes to the "filter named register" function I described in the Wiki
  3. The code now works and produces the desired .json file
  4. Cannot proceed from here due to lack of information

Your Environment

Running Node-RED from a docker container under Windows 10.

  • (x) I am using just the Node-RED package and got modbus-serial package installed with it
  • ( ) I have installed modbus-serial package global from source (using git clone)
  • ( ) I have installed modbus-serial as a global package (using npm i -g)

Yes, modbus-serial is the name but it does all, TCP and Serial.
The node-modbus package is just for the Modbus Server node.

Some example files are to find in the extras folder.

The flaq for the payload changes the output of the node:
