SI Ethernet
  • Overview

SI-Ethernet supports real-time Ethernet (IEEE 1588 V2 Precision Time Protocol), HTTP, SMTP, EtherNet/IP and Modbus TCP/IP. The module can be used to provide high speed drive access, global connectivity and integration with IT network technologies, such as wireless networking.


  • Real-time Ethernet (IEEE 1588 V2 Precision Time Protocol), Modbus TCP/IP, EtherNet/IP
  • Network synchronization of less than 1 μs jitter (typically <200 ns)
  • 1 ms cycle time for synchronous cyclic data
  •  Bandwidth protection through a network gateway that manages non-real-time Ethernet messages
  •  Master/follower and peer-to-peer communications capabilities
  • Addressing is IP based Dual 100 BASE-TX RJ45 connectors with support for shielded twisted pair, full-duplex 100 Mbps connectivity with auto crossover correction
  •  Integrated switches allow for use of line networks i.e. daisy chaining
  •  Both ports operate in full duplex mode as a network switch
  •  LED indication of network port activity
