func NewEtherCAT

func NewEtherCAT() *EtherCAT

NewEcat creates and returns a new EtherCAT packet with a default header and an empty list of datagrams.

Returns:

• ecat: New EtherCAT packet

func (*EtherCAT) AppendDatagram

func (e *EtherCAT) AppendDatagram(data datagram.Datagram) error

AppendDatagram appends a new EtherCAT datagram to the packet and updates the packet header(Length). It returns an error if the new header length exceeds the valid range.

Parameters:

• data (datagram.EcatDatagram): EtherCAT datagram to append

Returns:

• error: Error if the new header length exceeds the valid range

func (EtherCAT) Bytes
