IEC ------- DEFAULT THRESHOLD
M_ME_NC_1 analog data. These settings group the L60 analog data into types: current, voltage, power, energy, and other.
Each setting represents the default threshold value for all M_ME_NC_1 analog points of that type. For example, to trigger
spontaneous responses from the L60 when any current values change by 15 A, the
ting should be set to 15. Note that these settings are the default values of the deadbands. P_ME_NC_1 (parameter of mea-
sured value, short floating point value) points can be used to change threshold values, from the default, for each individual
M_ME_NC_1 analog point. Whenever power is removed and re-applied to the L60, the default thresholds will be in effect.
setting decides whether multiple client connections are accepted or not. If redundancy is set to Yes,
two simultaneous connections can be active at any given time.
The IEC 60870-5-104 and DNP protocols cannot be used simultaneously. When the IEC 60870-5-104 FUNCTION
setting is set to "Enabled", the DNP protocol will not be operational. When this setting is changed it will not become
active until power to the relay has been cycled (off-to-on).
k) SNTP PROTOCOL
The L60 supports the Simple Network Time Protocol specified in RFC-2030. With SNTP, the L60 can obtain clock time over
an Ethernet network. The L60 acts as an SNTP client to receive time values from an SNTP/NTP server, usually a dedicated
product using a GPS receiver to provide an accurate time. Both unicast and broadcast SNTP are supported.
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,
is "Enabled", the L60 attempts to obtain time values from the SNTP/NTP server. Since many time
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.
