#include "Ethercat.h" 

EthercatMaster master; 
EthercatDevice_CiA402 motor;

void setup() {
  Serial.begin(115200);
  while (!Serial);
  
  master.begin(); 
  motor.attach(0, master);
  master.start(); 
  
  motor.enable();
} 

void loop() {
  Serial.print("Error Code: ");
  Serial.println(motor.getErrorCode());
  delay(1000);
  // ...
}
