3.2.3 PTP Version 2 (BC) (MS20/MS30,
PowerMICE, MACH 104, MACH 1040)
PTP version 2 provides considerably more settings. These support
- faster reconfiguration of the PTP network than in PTP version 1
- greater precision in some environments.
You select the PTP version you will use in the Time:PTP:Global dialog.
Global
Parameter Meaning Possible Values Default Setting
Priority 1 The clock with the lowest priority 1
becomes the reference clock
(grandmaster).
0-255 128
Priority 2 If all the relevant values for selecting
the reference clock are the same for
multiple devices, the clock with the
lowest priority 2 is selected as the
reference clock (grandmaster).
0-255 128
Domain number Assignment of the clock to a PTPv2
domain. Only clocks with the same
domain are synchronized.
0-255 0

Parameter Meaning Possible Values Default Setting
Two Step Displays the clock mode of the
device
No
v2-boundary-clock-onestep No
v2-boundary-clock-twostep Yes
Number of BCs
to grandmaster
Number of boundary clocks
between PTP reference clock and
this device
Offset to Master
[ns]
Deviation of the local clock from the
reference clock in nanoseconds.
Runtime to
Master [ns]
Single signal runtime between the
local device and the reference clock
in nanoseconds. The display
depends on the port setting
“Runtime measuring mechanism”.
