Usage

Sensor values are readable through the generic Capabilities trait independent of the actual connection and protocol. Proxy objects provide concrete implementations of this trait:

• Modbus RTU
• Mock (only for testing and simulation)

Example

Build

cargo build --example modbus-rtu

Run

cargo run --example modbus-rtu

The default log level is Info.

Due to known limitations in tokio-proto the serial port within the Modbus RTU context needs to be reconnected after a slave failed to send a response in time, i.e. after the request was aborted by the client due to a timeout. The example demonstrates how to cope with this situation and displays a warning message.
