[Ethercat Device]

Description

Read 32-bit data of SII EEPROM starting from the specified offset for the slave device.

Syntax

uint32_t readSII32(uint32_t offset, uint32_t timeout_ms = 500);

Parameters

  • [in] uint32_t offset
    The offset value of SII EEPROM for such EtherCAT slave device.
  • [in] uint32_t timeout_ms
    Timeout in milliseconds.

Return Value

Return the 32-bit data of SII EEPROM.

Comment

This function must be called after a successful execution of EthercatMaster::begin(). This function is blocking and cannot be called within the Cyclic Callback.

Example

#include "Ethercat.h"

EthercatMaster master;
EthercatDevice_Generic slave;

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

  master.begin();
  slave.attach(0, master);
}

void loop() {
  Serial.print("Value: ");
  Serial.println(slave.readSII32(0), HEX);
  delay(1000);
}
