CIP Sync

CIP Sync is the name given to the time synchronization technology for the Common Industrial Protocol (CIP). CIP Sync is based on the IEEE 1588 V2 (IEC 61588) standard – Precision Clock Synchronization Protocol for Networked Measurement and Control Systems, commonly referred to as the Precision Time Protocol (PTP). The standard is designed for, but not limited to, local area networks like Ethernet. The protocol provides a standard mechanism to synchronize clocks across a network of distributed devices.
TIP:
CIP Sync is only supported on Ethernet I/P and on the
ControlLogix
 backplane.
CIP Sync defines the Time Sync Object. The Time Sync Object provides a CIP interface to the IEEE 1588 (IEC 61588) Standard.
CIP Sync technologies creates the capabilities to perform these functions.
  • Create Sequence of Events Applications
  • System-wide synchronization for CIP-based Networks
  • Implementation of IEEE 1588 on CIP Networks
  • Integrated Motion Applications and Coordinated and Schedule Outputs
CIP Sync supports IEEE 1588 V2 synchronization standard. In this architecture, a grandmaster clock provides a master time reference for the system time. The grandmaster could be:
  • An Ethernet switch that supports IEEE 1588 V2,
  • A Symetricom Grandmaster GPS receiver or equivalent
  • A 1756-EN2X module with firmware revision 3.x or later, or
  • A
    ControlLogix
     or
    GuardLogix
     controller with firmware revision V18 or later
