Leanpub Live-Book

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.

The [serialport][14] optional dependency is just to list all ports on your system in the client configuration.
It is not the [serialport][14] version to work with Modbus at runtime.
For that check the [modbus-serial][2] package.json, please!
The [modbus-serial][2] supports and works for TCP connections in that package, too.
All Modbus commands running on [modbus-serial][2].

If you get in trouble with TCP connections, then check and test with just [modbus-serial][2] first, please!

If you get in trouble with Serial connections, then check with just [serialport][14] first, please!

The package will catch network and other errors of the 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},...
