GE Multilin L60 Line Phase Comparison Relay 5-275 SETTINGS 5.2 PRODUCT SETUP5If SNTP functionality is enabled at the same time as IRIG-B, the IRIG-B signal provides the time value to the L60 clock foras long as a valid signal is present. If the IRIG-B signal is removed, the time obtained from the SNTP server is used. Ifeither SNTP or IRIG-B is enabled, the L60 clock value cannot be changed using the front panel keypad.To use SNTP in unicast mode, SNTP SERVER IP ADDR must be set to the SNTP/NTP server IP address. Once this address isset and SNTP FUNCTION is “Enabled”, the L60 attempts to obtain time values from the SNTP/NTP server. Since many timevalues are obtained and averaged, it generally takes three to four minutes until the L60 clock is closely synchronized withthe 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 SNTP SERVER IP ADDR setting to “0.0.0.0” and SNTP FUNCTION to “Enabled”. TheL60 then listens to SNTP messages sent to the “all ones” broadcast address for the subnet. The L60 waits up to eighteenminutes (>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.5.2.5 MODBUS USER MAPPATH: SETTINGS Ö PRODUCT SETUP ÖØ MODBUS USER MAPThe Modbus User Map provides read-only access for up to 256 registers. To obtain a memory map value, enter the desiredaddress in the ADDRESS line (this value must be converted from hex to decimal format). The corresponding value is dis-played in the VALUE line. A value of “0” in subsequent register ADDRESS lines automatically returns values for the previousADDRESS lines incremented by “1”. An address value of “0” in the initial register means “none” and values of “0” will be dis-played for all registers. Different ADDRESS values can be entered as required in any of the register positions.
