The Technicians Guide to Precision Time Protocol has been specifically developed by Field Technicians and Maintenance Engineers for ease of learning IEEE1588-2019 PTP as quickly as possible. With this short guide an understanding of this widely used and highly specialized time synchronization protocol can be discerned and can be implemented on the shop floor or in the field. Useful simplistic examples for the many varities of how PTP operates have been included. Tips and common problems when implementing PTP are covered.
