Note: About the time service:
1. Enable/Disable Daylight Savings Time parameter: If the Enable/Disable
check box is selected, the module automatically corrects the local time to
account for daylight savings time. Therefore, no action is required, since the
daylight saving time start and end are automatically changed each year.
2. Polling Time Parameter: The time (in seconds) is the time between time
updates from the NTP server. The default is 5 seconds.
3. Storing the Time Service Configuration: The last time service configuration
is saved internally in the Ethernet module.
4. Replacing the Ethernet Module: If the Ethernet module has to be replaced, the
stored configuration is lost, and the system returns to the default configuration.
