Features of EtherNet/IP
Reduced Wiring
Compared with parallel wiring, EtherNet/IP employs a standard Ethernet cable which substantially reduces the number of necessary wires, wiring time and cost.
Detachable communication connectors provide you with simple wiring between nodes and easy network separation or reconstruction.
Specified
You can use the generic Ethernet hub or Ethernet switch for the EtherNet/IP. However, be sure to a use product complying with the industrial standards or noise resistant Ethernet cable (STP cable). If you use an office use product or UTP cable, it may causes communication errors and may not offer the proper performance.
Open Standard (Multi-vendor)
Due to an open communication standard, various devices from many manufacturers are available. Standardized communication connectors provide you with easy network construction.
The maintenance spare parts stored on site (factory, etc.) can be reduced because different manufacturers’ devices are used in case of a breakdown. Similar products are available around the world due to a global standard EtherNet/IP.
