#include "Ethercat.h"

EthercatMaster master;
EthercatDevice_QECR11HU9S slave;

void CyclicCallback() {
  slave.update();
}

void setup() {
  Serial.begin(115200);

  master.begin();
  slave.attach(0, master);
  master.attachCyclicCallback(CyclicCallback);
  master.start();
}

void loop() {
  Serial.print("Enable: ");
  Serial.println(slave.mpgReadEnableSwitch());
  delay(1000);
  // ...
}
