Modbus User Map - GE L60 Instruction Manual

5 SETTINGS
If SNTP functionality is enabled at the same time as IRIG-B, the IRIG-B signal provides the time value to the L60 clock for
as long as a valid signal is present. If the IRIG-B signal is removed, the time obtained from the SNTP server is used. If
either SNTP or IRIG-B is enabled, the L60 clock value cannot be changed using the front panel keypad.
To use SNTP in unicast mode,
set and is "Enabled", the L60 attempts to obtain time values from the SNTP/NTP server. Since many time
SNTP FUNCTION
values are obtained and averaged, it generally takes three to four minutes until the L60 clock is closely synchronized with
the SNTP/NTP server. It may take up to two minutes for the L60 to signal an SNTP self-test error if the server is offline.
To use SNTP in broadcast mode, set the
L60 then listens to SNTP messages sent to the "all ones" broadcast address for the subnet. The L60 waits up to eighteen
minutes (>1024 seconds) without receiving an SNTP broadcast message before signaling an SNTP self-test error.
The UR-series relays do not support the multicast or anycast SNTP functionality.
