RegisterMap class

Point table (register map) for a Modbus device.

Example:

final registerMap = RegisterMap(
  slaveId: 1,
  registers: [
    RegisterDefinition(name: 'temp', address: 100, type: RegisterType.inputRegister, dataType: DataType.float32),
    RegisterDefinition(name: 'setpoint', address: 200, type: RegisterType.holdingRegister, dataType: DataType.float32),
  ],
);

// Read all registers
final values = await registerMap.readAll(client);
print('Temperature: ${values['temp']} °C');

// Write a value
await registerMap.write(client, 'setpoint', 25.5);

Constructors

RegisterMap({required int slaveId, required List<RegisterDefinition> registers, String? deviceName})

RegisterMap.fromJson(String jsonString)
