1588-2019

IEEE Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems

In this standard, a protocol is defined that provides precise synchronization of clocks in packet-based networked systems. Synchronization of clocks can be achieved in heterogeneous systems that include clocks of different inherent precision, resolution, and stability. The protocol supports synchronization accuracy and precision in the sub-microsecond range with minimal network and local computing resources. Customization is supported by means of profiles. The protocol includes default profiles that permit simple systems to be installed and operated without the need for user management. Sub-nanosecond time transfer accuracy can be achieved in a properly designed network.

1588-2002

IEEE Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems

Replaced by IEC 61588-2004 (SH95292 or SS95292) Dual-logo document Abstract: A protocol to synchronize independent clocks running on separate nodes of a distributed measurement and control system to a high degree of accuracy and precision is specified. The protocol is independent of the networking technology, and the system topology is self-configuring.

1588-2008

IEEE Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems

This standard defines a protocol enabling precise synchronization of clocks in measurement and control systems implemented with technologies such as network communication, local computing and distributed objects. The protocol is applicable to systems communicating by local area networks supporting multicast messaging including but not limited to Ethernet. The protocol enables heterogeneous systems that include clocks of various inherent precision, resolution, and stability to synchronize to a grandmaster clock. The protocol supports system-wide synchronization accuracy in the sub-microsecond range with minimal network and local clock computing resources. The default behavior of the protocol allows simple systems to be installed and operated without requiring the administrative attention of users. The standard includes mappings to UDP/IP, DeviceNet and a layer-2 Ethernet implementation. An Interpretation is available at http://standards.ieee.org/reading/ieee/interp/1588-2008.html
