server
If this option is selected, the CPU Unit’s clock is set to
the time at the SNTP server’s clock.
Not
checked
Auto Adjustment Set the time at which the SNTP server is to be
accessed to synchronize the clocks.
When the time that is set here arrives, the SNTP
server is accessed and the CPU Unit clock is
adjusted to match the SNTP server clock.

Designation
Method
Select whether the SNTP server used for automatic
clock adjustment is to be specified by IP address or
by host domain name (i.e., by host name).
IP Address
IP Address

0.0.0.0
Host Name
Set the host domain name (i.e., the host name) for
the SNTP server that is to be used for automatic
