3.2 PTP (IEEE 1588)
Precise time management is required for running time-critical applications via
a LAN.
The IEEE 1588 standard with the Precision Time Protocol (PTP) describes a
procedure that assumes one clock is the most accurate and thus enables
precise synchronization of all clocks in a LAN.
For devices without a real-time (RT) module (module without timestamp
unit):
X enable/disable the PTP function in the PTP dialog.
X select PTP mode in the PTP dialog.
–Select v1-simple-mode if the reference clock uses PTP Version 1.
–Select v2-simple-mode if the reference clock uses PTP Version 2.
The following sections apply to devices with support of real-time (RT)
modules (modules with timestamp unit).
