how to type the right address in modbusmaster library function

i now have this
modbus rtu address in my plc instruction ,and i write a value in D0 REGITER in the attachment,i now want to access the regiter by modbusmaster library with a arduino + rs485 module ,things are connected,but i can get the register value in the serial monitor.i can capture the wave in my scope when there is a request

/*

RS485_HalfDuplex.pde - example using ModbusMaster library to communicate
with EPSolar LS2024B controller using a half-duplex RS485 transceiver.

This example is tested against an EPSolar LS2024B solar charge controller.

We're using a MAX485-compatible RS485 Transceiver.
Rx/Tx is hooked up to the hardware serial port at 'Serial'.
The Data Enable and Receiver Enable pins are hooked up as follows:

#define MAX485_RE_NEG 3
#define MAX485_DE 2

int myInts[6];

// instantiate ModbusMaster object
ModbusMaster node; // Se llamará ModbusMaster como node

void preTransmission()
{
digitalWrite(MAX485_RE_NEG, 1); // Es el modo de transmisión
digitalWrite(MAX485_DE, 1);
}

void postTransmission()
{
digitalWrite(MAX485_RE_NEG, 0); // Es el modo de recepción
digitalWrite(MAX485_DE, 0);
}

void setup()

pinMode(MAX485_RE_NEG, OUTPUT);
pinMode(MAX485_DE, OUTPUT);

// Empieza en modo de recepción
digitalWrite(MAX485_RE_NEG, 0);
digitalWrite(MAX485_DE, 0);

// Modbus communication runs at 115200 baud
Serial.begin(9600);

// Modbus slave ID 1
node.begin(1, Serial);
// Callbacks allow us to configure the RS485 transceiver correctly
node.preTransmission(preTransmission);
node.postTransmission(postTransmission);
}

void loop()

uint8_t ResultadoEscritura;
bool state=1;

// for (int j = 15; j <= 100; j = j + 10 ) {
// ResultadoEscritura = node.writeSingleRegister(0x0000, j); //HERE IS 226, Lee un registro
// delay(1000);
// }

ResultadoLectura = node.readHoldingRegisters(0x0000, 1); //HERE IS 226, Lee un registro
// ResultadoEscritura = node.writeSingleRegister(0x0161, state); //HERE IS 226, Lee un registro
// state = !state;

if (ResultadoLectura == node.ku8MBSuccess)
{
Serial.print("\nPV2: ");
Serial.println(node.getResponseBuffer(1));
}
else {
Serial.print("\nError en conexión: ");
Serial.println(ResultadoLectura, HEX); // Debe dar 0
Serial.println(ResultadoEscritura, HEX); // Debe dar 0

}

delay(1000);
}

this is my setup :o
and i have a post in redit
