This is a library to provide Modbus client (formerly known as master), server (formerly slave) and bridge/gateway functionalities for both Modbus RTU and TCP protocols.
Modbus communication is done in separate tasks, so Modbus requests and responses are non-blocking. Callbacks are provided to prepare or receive the responses asynchronously.
Key features:
- for use in the Arduino framework
- non blocking / asynchronous API
- server, client and bridge modes
- TCP (Ethernet, WiFi and Async) and RTU interfaces
- all common and user-defined Modbus standard function codes
This has been developed by enthusiasts. While we do our utmost best to make robust software, do not expect any bullet-proof, industry deployable, guaranteed software. See the license to learn about liabilities etc.
We do welcome any ideas, suggestions, bug reports or questions. Please use the "Issues" tab to report these!
Have fun!
