EthercatDevice.pdoWrite16()

[Ethercat Device]

Description

Write 16-bit output process data which starting from the specified offset for such EtherCAT slave device.

Syntax

int pdoWrite16(uint32_t offset, uint16_t value);

Parameters

• [in] uint32_t offset
  The offset value of output process data for such EtherCAT slave device.
• [in] uint16_t value
  The 16-bit value to be written to output process data for such EtherCAT slave device.

Return Value

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

Comment

This function must be called after a successful execution of EthercatMaster::start(). This function is non-blocking and can be called within the Cyclic Callback.

Example

#include "Ethercat.h"

EthercatMaster master;
EthercatDevice_Generic slave;

void setup() {
  master.begin();
  slave.attach(0, master);
  master.start(1000000);
}

void loop() {
  slave.pdoWrite16(0, 0x5555);
  delay(500);
  slave.pdoWrite16(0, 0xAAAA);
  delay(1000);
}
