EtherNet IP Bus
EtherNet/IP (EtherNet Industrial Protocol) is an Ethernet-based fieldbus which is primarily used in the field of automation technology. The bus was developed by Allen-Bradley and later transferred to the ODVA organization as an open standard. EtherNet/IP was then published as an open industry standard in the year 2000.
The typical cycle time of an EtherNet/IP network is 10ms, which means that the system is capable of meeting real-time software requirements for industrial I/Os. For tough real-time requirements, for example in servo drives, protocol extensions are available that reduce the jitter for controlling servomotors to values in the sub-microsecond range using precise time synchronization in line with IEEE1588.
