IEEE Std 1528.2 is a standard for "Recommended Practice for the Implementation of a Data Exchange Subsystem Using a PTP (Precision Time Protocol) Master" within the context of power systems and related applications. This standard provides guidelines on implementing a Precision Time Protocol (PTP) master in a data exchange subsystem. PTP, also known as IEEE 1588, is a protocol used to synchronize clocks on a network to a precise timing source.
The "work" of IEEE 15288.2 is the difference between a project that explodes during integration and one that flies on the first try. Do the work.
