Synchronizing the system time in the
Configuration SNTP Client
In "External server address" you enter the IP address of the
SNTP server from which the device periodically requests the sys-
tem time.
In "Redundant server address" you enter the IP address of the
SNTP server from which the device periodically requests the sys-
tem time, if it does not receive a response to a request from the
"External server address" within 0.5 seconds.
Note: If you are receiving the system time from an external/redun-
dant server address, you do not accept any SNTP broadcasts
(see below). Otherwise you can never distinguish whether the
device is displaying the time from the server entered, or that of an
SNTP broadcast packet.
In "Server request interval" you specify the interval at which the
device requests SNTP packets (valid entries: 1 second to 3600
seconds, on delivery: 30 seconds).
With "Accept SNTP Broadcasts" the device takes the system
time from SNTP broadcast/Multicast packets that it receives.
