Note: About the time service:

1. Automatically adjust clock for daylight savings change parameter: If this

check box is selected, the module automatically corrects the local time to

account for daylight saving 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.
