6–8 350 FEEDER PROTECTION SYSTEM – INSTRUCTION MANUAL
S1 RELAY SETUP CHAPTER 6: SETPOINTS
SNTP MODE:
Range: Disabled, Unicast, Anycast, Broadcast
Default: Disabled
When “Disabled” is selected for this setting, SNTP time synchronization is disabled.
SNTP PORT:
Range: 0 to 65535
Default: 0
This setting configures the port that 350 .is using.
SNTP SERVER IP ADR:
Range: Standard IP Address format
Default: 000.000.000.000
This setting must be set to the SNTP/NTP server IP address.
UTC OFFSET:
Range: -24.00 to 24.00
Default: 0.00
If this setting is different to zero, this value will be used to convert from UTC to local time
for SNTP synchronization.
NOTE:
Refer to the 3 Series Communications Guide for details on SNTP MODE, SNTP PORT, and
SNTP SERVER IP ADR.

PTP FUNCTION
Range: Enabled, Disabled
Default: Disabled
When “Disabled” is selected for this setting, PTP is disabled on the port. The relay does
not generate, or listen to, PTP messages on the port.
PTP STRICT POWER PROFILE
Range: Enabled, Disabled
Default: Disabled
Power profile (IEEE Std C37.238™ 2011) requires that the relay selects as a grandmaster:
• only power profile compliant clocks
• that the delivered time has a worst-case error of ±1 μs
• and, that the peer delay mechanism be implemented.
With the Strict Power Profile setting set to “Enabled”, the relay selects as the master only
clocks displaying the IEEE_C37_238 identification codes. It uses a port only when the
peer delay mechanism is operational. With the
Strict Power Profile setting set to
“Disabled”, the relay uses clocks without the power profile identification when no power
profile clocks are present, and uses ports even if the peer delay mechanism is non-
operational. This setting applies to all of the relay’s PTP-capable ports.
PTP DOMAIN NUMBER
Range: 0 to 255
Default: 0
The setting is set to the domain number of the grandmaster-capable clock(s) to which
they can be synchronized. A network can support multiple time distribution domains,
each distinguished with a unique domain number. More commonly, there is a single
domain using the default domain number zero. The setting applies to all of the relay’s
PTP-capable ports.
