This is a library to provide Modbus client (formerly known as master), server (formerly slave) and bridge/gateway functionalities for Modbus RTU, ASCII and TCP protocols.
|
|
|
|
For Modbus protocol specifications, please refer to the [Modbus.org site](https://www.modbus.org/specs.php)!
|
|
|
|
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
|
|
- designed for ESP32, various interfaces supported; async versions run also on ESP8266
|
|
- non blocking / asynchronous API
|
|
- server, client and bridge modes
|
|
- TCP (Ethernet, WiFi and Async), ASCII and RTU interfaces
|
|
- all common and user-defined Modbus standard function codes
|
