Network Time Tab Field Descriptions
You can configure your SNTP client in the IOLAN to automatically synchronize the IOLAN’s time.
Configure the following parameters:
SNTP Mode
SNTP Version
Primary Host
Secondary Host
The SNTP mode.
Data Options:
z None—SNTP is turned off.
z Unicast—Sends a request packet periodically to the Primary host. If
communication with the Primary host fails, the request will be sent to the
Secondary host.
z Multicast—Listen for any broadcasts from an SNTP server and then
synchronizes its internal clock to the message.
z Anycast—Sends a request packet as a broadcast on the LAN to get a
response from any SNTP server. The first response that is received is used
to synchronize its internal clock and then operates in
Unicast mode with
that SNTP server.
Default: None
Version of SNTP.
Range: 1-4
Default: 4
The name of the primary SNTP server from the IOLAN host table. Valid with
Unicast and Multicast modes, although in Multicast mode, the IOLAN will
only accept broadcasts from the specified host SNTP server.
The name of the secondary SNTP server from the IOLAN host table. Valid
with
Unicast and Multicast modes, although in Multicast mode, the IOLAN
will only accept broadcasts from the specified host SNTP server.
