These enhancements include the implementation of the Resilient Ethernet
Protocol (REP), DHCP per port and the CIP Sync Time Protocol. The REP
is a high-speed ring protocol that allows switches to be connected in a
ring, ring segment or nested ring segments. DHCP per port allows the
switch to assign IP addresses to end devices connected to the switch.
CIP Sync, which is ODVA’s implementation of the IEEE 1588 Precision
Time Protocol, allows automation equipment to achieve clock
synchronization within the 100 nanosecond range.Rockwell Automation Inc.www.rockwellautomation.com440.646.4184
