  • Page 54: Ethernet/Ip Technology

    SD500 – ETHERNET POWER ELECTRONICS 1.1.1. Ethernet/IP Technology Introduced at the beginning of 2000, Ethernet/IP is one of the pioneers in Ethernet solutions for industrial environment. The main reason is that it is based on open technology, using the same application layer as DeviceNet and ControlNet, and it is called Common Industrial Protocol (CIP).

  • Page 55: Cip Protocol

    SD500 – ETHERNET POWER ELECTRONICS With I/O messages, the application data field only contains input/output data in real time. The meaning of data is linked to an identifier defined when connection is established, reducing the processing time in the node at execution time. This type of messages provides high efficiency, low load and the required performance for real-time control.
  • Page 56 SD500 – ETHERNET POWER ELECTRONICS The CIP model is, on the upper layers, a model only focused to objects.
