The Priority 2 parameter (see IEEE 1588-2008, clause 7.6.2.3) is
used if several devices have the same Priority 1 parameter value
and the same clock quality (class, accuracy and variance). The
Priority 2 parameter thus allows a finer grained ordering among
otherwise equivalent clocks (see IEEE 1588-2008, clause 6.6.2.3).
Lower values take precedence.
Use this field to specify the domain number. The domain number
specifies the PTP domain (see IEEE 1588-2008, clause 7.1) in
which the OTMC 100 participates. All clocks in a network that shall
be synchronized to each other must participate in the same PTP
domain, i.e., have the Domain number parameter set to the same
value.
Use this field to specify the grandmaster identity to be transmitted in
IEEE C37.238 TLV. By sending this ID, the OTMC 100 identifies
itself as a valid power profile grandmaster. A power profile slave will
ignore all masters that do not provide a setting for this field. Only
available for Power Profile (OTMC 100p only).
Use this field to specify the network time inaccuracy in ns to be
transmitted in IEEE C37.238 TLV. See IEEE C37.238-2011, clause
5.13. Only available for Power Profile (OTMC 100p only).
Use this field to specify the engineered network time inaccuracy in
ns. This value is set at the end device to represent the worst
network time inaccuracy from this device to all preferred
grandmasters. See "EngTimeInacc" in IEEE C37.238-2011. Only
available for Power Profile (OTMC 100p only).
Use this field to specify the maximum time inaccuracy in ns that the
device contributes to the network time inaccuracy. See
IEEE C37.238-2011, clause 5.13. Only available for Power Profile
(OTMC 100p only).
Use this field to specify the offset from master limit in ns to generate
OfstExceedsLimit event. If this value is zero, no event is generated.
See "OfstExceedsLimit" in IEEE C37.238-2011. Only available for
Power Profile (OTMC 100p only).
