  • Page 4: Ethernet/Ip

    As an application layer (number 7 in the OSI model), EtherNet/IP uses the Common Industrial Protocol (CIP™) for process control. ELAP MEM-BUS encoder meets all the requirements of the EtherNet/IP protocol according to IEC61784-1 and those of the encoder profile.
  • Page 5 The MAC address (MAC ID) consists of 6 bytes. The first three bytes identify the manufacturer. The last three bytes are unique to the device. The MAC address of ELAP MEM-BUS encoders is 60-D7-E3-1x-xx-xx. EtherNet/IP is based on the standard Ethernet frame, which consists of the Ethernet header, the Ethernet data, and the Ethernet trailer.

  • Page 6: The "Producer / Consumer" Model

    1.5 EtherNet/IP™ topologies ELAP MEM-BUS encoders can be connected in any of three network topologies: star, linear, or Device Level Ring (DLR). The linear topology uses the embedded switching capability to form a daisy chain style network that has a beginning and an end.

  • Page 7: Cip™ Object Model

    EtherNet/IP™ ENCODER MEM-BUS Instruction Manual A DLR network is a single-fault-tolerant ring network that is intended for the interconnection of automation devices. DLR topology is advantageous as it can tolerate a break in the network. If a break is detected, the signals are sent out in both directions.
