EthercatDevice.pdoBitWrite()

[Ethercat Device]

Description

Write the specified bit value to the output process data of such slave device.

Syntax

int pdoBitWrite(uint32_t bit_offset, uint8_t value);

Parameters

• [in] uint32_t bit_offset
  The bit offset value of output process data for such EtherCAT slave device.
• [in] unit_8_t value
  The 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.pdoBitWrite(0, 1);
  delay(500);
  slave.pdoBitWrite(0, 0);
  delay(1000);
}
