To use SNTP in anycast mode, set the
Function
setting to “ANYCAST”. Anycast mode is designed for use with a set of
cooperating servers whose addresses are not known beforehand by the client. The G650 sends a request to a multicast
group address assigned by IANA for NTP protocol. This address is 224.0.1.1 and a group of SNTP/NTP servers listens to
it. Upon receiving a request each server sends a unicast response to the SNTP/NTP client. The G650 relay binds to the
first unicast message received from any server. Then it continues operating with SNTP/NTP server in unicast mode. Any
further responses from other SNTP/NTP servers are ignored. In unicast mode of operation the chosen time server can go
offline, in that case it takes about one minute for the G650 to signal an SNTP FAIL state and to switch again to anycast
mode to try to find another time server. In anycast mode the G650 tries to send multicast messages up to five minutes
before signalling an SNTP FAIL state.
The G650 relay does not support the multicast mode of SNTP functionality.
5.2.2 MODBUS USER MAP
