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	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
SNTP Version	Version of SNTP.
	Range: 1-4
	Default: 4
Primary Host	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.
Secondary Host	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.
