TIDA-00792: Connection to an Arduino UNO via SMBus

We are currently trying to establish communication TIDA-00792 with an Arduino UNO board based on SMBus communication. But we are not able to succeed. 

* 48V DC power supply is used to power up the board

* Regout is 2.5V

* Connected pins:

SMBC --> Arduino SCL

SMBA --> Arduino SDA

* Not very clear about the address (0x0B or 0x08 or 0x16 or 0x17)

Code:

#include <Wire.h>
void setup() {
  Wire.begin(); // join i2c bus (address optional for master)
  Serial.begin(9600);
}
void loop()
{
  delay(1000);
  Serial.println("write data");
  Wire.beginTransmission(0x16); // 
  Wire.write(0x09);
  Wire.endTransmission();
  Wire.requestFrom(0x0B, 2);    // request 6      bytes from slave device #8
  String response = "";
  while (Wire.available()) { // slave may send less than requested
    char c = Wire.read(); // receive a byte as character
    //Serial.print(c);         // print the character
    response += c;
  }
  Serial.println(response);
}
