Automatic Clock Adjustment Function

Specifying Servers by Host Name

The built-in clock of the PLC connected to the Ethernet can be automatically

adjusted, with the SNTP server clock taken as the standard. Automatic adjust-

ments through the entire system enable the various records generated by pro-

duction equipment to be managed according to clock information and

The PLC can acquire clock information from the SNTP server at a particular

time or when a dedicated bit turns ON, and it can refresh the internal clock

information automatically.

(1) An SNTP server is required to use this function.

(2) SNTP server settings require specialized knowledge, so they should al-

ways be handled by the network administrator.

(3) When using the Internet, depending on the condition of the network it

may not be possible to acquire the clock information.

SNTP servers can be specified by host name rather than by IP address by

using of the DNS client function.

This enables automatic searches for IP addresses for purposes such as sys-

tem checking, even when the IP addresses for servers have been changed.

(1) A DNS server is required to specify servers by IP address.

(2) The IP address is specified directly for the DNS server.
