[Modbus]
描述
Set the starting address of the register of the Slave device you want to write to, and use it with unquoted writeMultipleCoils or writeMultipleRegisters. See the 範例 to illustrate.
語法
node1.beginTransmission(write_address)
參數
node1: ModbusMasterNode object.write_address: The starting address of the register of the Slave device you want to write to.
範例
#include <Arduino.h>
#include <Modbus86.h>
ModbusMaster bus1;
ModbusMasterNode node2;
uint8_t reg[2];
uint8_t result;
void setup()
{
while(!Serial);
Serial1.begin(115200);
bus1.begin(MODBUS_RTU, Serial1);
node2.attach(16, bus1);
reg[0] = 0x1234;
reg[1] = 0xabcd;
node2.beginTransmission(5);
node2.send(reg[0]);
node2.send(reg[1]);
result = node2.writeMultipleRegisters();
if (result != MODBUS_SUCCESS) {
Serial.print("ErrorCode: ");
Serial.println(result);
}
}
