PTP Profile
Each PTP device has a set of attributes as define by IEEE1588-2008. On the inverter the default attributes values are set as follows. Note that
some may be modified by a parameter.
Attribute
domainNumber
slaveOnly
logAnnounceInterval
logSyncInterval
logMinDelayReqInterval
announceReceiptTimeout
Description
A domain consists of one or more PTP devices
communicating with each other. Devices on the
same domain will have the same domain number.
When slaveOnly is TRUE the PTP device may only
be a slave and not become a master clock.
A port in the MASTER state will periodically transmit
an Announce message.
Announce messages will be transmitted such that the
logarithm to the base 2 of the mean value of the
interval in seconds between message transmissions
is the value of the
logAnnounceInterval.
A port in the MASTER state will periodically transmit
a Sync message.
Sync messages will be transmitted such that the
logarithm to the base 2 of the mean value of the
interval in seconds between message transmissions
is the value of the logSyncInterval.
The logMinDelayReqInterval will specify the
minimum permitted mean time interval between
successive Delay_Req messages.
This value is determined and advertised by a master
clock based on the ability of the master clock to
process the Delay_Req message traffic.
The value of announceReceiptTimeout will specify
the number of announceInterval that has to pass
without receipt of an Announce message
