[Ethercat Device]
Description
Write 64-bit output process data which starting from the specified offset for such EtherCAT slave device.
Syntax
int pdoWrite64(uint32_t offset, uint64_t value);
Parameters
[in] uint32_t offset
The offset value of output process data for such EtherCAT slave device.[in] uint64_t value
The 64-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.pdoWrite64(0, 0x5555555555555555ULL); delay(500); slave.pdoWrite64(0, 0xAAAAAAAAAAAAAAAAULL); delay(1000); }
