EthercatDevice.writeSII8()

[Ethercat Device]

描述

Write 8-bit data of SII EEPROM which starting from the specified offset for such EtherCAT slave device.

語法

int writeSII8(uint32_t offset, uint8_t value, uint32_t timeout_ms = 500);

參數

• [in] uint32_t offset
  The offset value of SII EEPROM for such EtherCAT slave device.
• [in] uint8_t value
  The 8-bit value to be written to SII EEPROM for such EtherCAT slave device.
• [in] uint32_t timeout_ms
  Timeout in milliseconds.

回傳值

Return an error code. If the returned value is zero, it indicates a successful execution of this function.

備註

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