Methods

connect() Future<bool>
Connect the port if not already done or disconnected
inherited
disconnect() Future<void>
Close the connection
inherited
getResponseTimeout(ModbusRequest request) Duration
If request has its own responseTimeout defined, then it will override this client responseTimeout.
inherited
getUnitId(ModbusRequest request) int
If request has its own unitId defined, then it will override this client unitId. If both unitId are not defined the a 0 is returned.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
send(ModbusRequest request) Future<ModbusResponseCode>
Sends a modbus request
inherited
toString() String
A string representation of this object.
