General Setup
Time Sync Request Interval (if Time Source=SCADA or Time Source=GPS and
SCADA)
When this interval (in minutes) expires the control will assert IIN1.4 (Need Time) on
every response until the master successfully writes absolute time and date using Object
50 variation 1. (Minimum: 1; Maximum: 10080; Step: 1; Default: Disabled)
Real-Time Clock Display
This is the date and 24-hour time display.
Active Time Source
This display indicates the time source as the Internal Clock (R3 control) or Real-Time
Clock (R2 control), or GPS Source.

Select from the drop-down list. GMT (UTC = 0) is the default.
All time-stamped files and the internal time are Universal Time, Coordinated (UTC),
also known as Greenwich Mean Time (GMT). Local time also can be displayed by using
the Control Time Zone and Daylight Savings Time settings.

to determine time.
