Domain Number; Network Protocol; Operation Mode; Delay Mechanism - GE Reason RT430 Technical Manual

o
3 seconds waiting time for receiving Announce messages.

Custom Profile: profile with all features freely configurable by a user.

Default Profile: profile partly configurable, with some predetermined features, which cannot be
modified. The non-editable characteristics are shown in its respective fields. The non-editable
characteristics are.
o

Domain number 0.

o
Priority 128 in both Ethernet ports.
o
Operation as master only.
4.5.2 Domain number
RT430 allows configuring the domain number to be identified by the PTP clock, so it only answers messages
from this domain. The domain number field allows selecting the domain number the unit will recognize, and it
can be 0, 1, 2, or 3.
4.5.3

Network protocol

RT430 uses PTP protocol in UDP/IPv4 (layer 3) network layer, according to IEEE1588 standard. The field
Network Protocol informs the UDP network protocol used by the unit.
4.5.4

Operation mode

The field operation mode allows configuring the operation mode according to the form RT430 sends its
messages, as follows:

One-step: Synchronism information and timestamp information are sent in the same data packet;

Two-step: synchronism information is sent in one data packet, and timestamp information is sent in
another data packet;
4.5.5

Delay mechanism

RT430 is capable of measuring the time a synchronism message takes to go through the path between
master and slave clocks using End-to-end and Peer-to-peer, according to IEEE1588 standard. The field
Delay mechanism allows configuring the type of measurement of the delay, as follows:

End-to-end: measurement of delay across the network between master clock and slave clock;

Peer-to-peer: measurement of delay only between master and slave clocks as neighbors.
