If you like that contributor's package for Modbus, then please give us your star at GitHub !
The P4NR B2B Community driven by Iniationware takes now care about the development and improvements for Modbus. Books, Tutorials and much more will be provided over time and if you need some support the P4NR team can help you. Bianco Royal is in partnership with the P4NR B2B Community.
We're excited to announce our Online Leanpub Book that covers each v5.x version in detail. This comprehensive guide is aimed to help you learn more about our nodes and the various options inside them. What's unique about this book is its "buy once, update forever" approach. We continuously update the content to bring the latest v5.x changes or new options with each v5.x release version.
Moreover, we're dedicated to responding to your queries. If you have a question, not only will we answer it, but we can also incorporate the insightful answers into the book's future editions. This ensures that all readers stay informed and engaged. Thanks to the P4NR B2B Community
Purchasing our book will greatly support us in our mission to incrementally improve Modbus for Node-RED and beyond with every release in the upcoming decade. Your support will undoubtedly contribute to building a robust Modbus for Node-RED ecosystem.
Node-RED contribution package for Modbus version overview:
Based on modbus-serial with TCP, C701, Telnet, Serial, RTU buffered, and ASCII
- stress tested with Node-RED v1.0.4 and Node.js LTS
- works with queueing per unit and round-robin scheduling
If you like that contributor's package for Modbus, then please give us your star at GitHub !
Run the following command in the root directory of your Node-RED install
npm install node-red-contrib-modbus
Run the following command for global install
npm install -g node-red-contrib-modbus
try these options on npm install to build if you have problems to install
--unsafe-perm --build-from-source
The serialport optional dependency is just to list all ports on your system in the client configuration. It is not the serialport version to work with Modbus at runtime. For that check the modbus-serial or jsmodbus package.json, please! The modbus-serial supports and works for TCP connections in that package, too. The jsmodbus package is just to provide a simple Modbus Server node. All Modbus commands running on modbus-serial.
If you get in trouble with TCP connections, then check and test with just modbus-serial first, please!
If you get in trouble with Serial connections, then check with just serialport first, please!
To update the dependencies or the whole package, you have just to install again.
npm show node-red-contrib-modbus@* version
To get a special version, please set the version with @M.M.F:
npm install node-red-contrib-modbus@3.6.1
or global by
npm install -g node-red-contrib-modbus@3.6.1
The Modbus-Flex-Server now got its own package. The P4NR team started to work on fixing the vm2 issue, but first, we think as the community here it has to get out of this package to close the issue on vm2 now. The P4NR team will split this package more in the next time into client and server packages to get a better development flow and to react faster on CVE or other issues. This is a first step to v6 of the package.

- use the Flow example to see how it works ...

Since v5.22+ the package will catch network and other errors of the client and server node. That means, you have to handle the error status of the node and Node-RED should not crash in the handled cases.
Debug will be activated by starting Node-RED with debug mode:
DEBUG=contribModbus*,modbus-serial node-red -v
or
DEBUG=contribModbus:{option},contribModbus:{option},...
see Wiki pages to get more options in detail
