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

The name of the secondary SNTP server from the IOLAN host table. Valid

 

with Unicast and Multicast modes, although in Multicast mode, the IOLAN
