    摘要: An electronic device communicates according to a network protocol that defines data packets, for example EtherCAT. The device has a processor for performing input control on incoming data packets and performing output control on outgoing data packets, and a shared FIFO buffer comprising a multiuser memory. An input unit receives input data, detects the start of a respective data packet, subdivides the data packet into consecutive segments, one segment having a predetermined number of data bytes, and transfers the segment to the FIFO buffer before the next segment has been completely received. The processor accesses, in the input control, the multiuser memory for processing the segment, and, in the output control, initiates outputting the output packet before the corresponding input data packet has been completely received. An output unit transfers the segment from the FIFO buffer, and transmits the segment to the communication medium.

    摘要: A master device has a slave port and a redundant slave port for communicating with slaves according to a network protocol, e.g. EtherCAT, via data packets including a circulating bit. The slaves are arranged in a sequence starting at the slave port, and are connected via a communication medium. A respective slave in the sequence detects whether the connection to its processing receiver is lost, and, if so, internally transfers any data packets from its forwarding arrangement to its processing arrangement, while setting the circulating bit. The master device has a switcher unit coupled to the redundant slave port and a last slave in the sequence. The switcher unit transfers data packets from the switcher receiver to the switcher transmitter, and detects whether a circulating bit is set. If so, the unit switches off said transferring and switches on a connection between the redundant slave port and the switcher for transferring replicated packets to the sequence. Advantageously, the system enables hot plug-in and also distributed clock synchronization, and reduces the processing requirements of the master device.
