Accuracy
– 99% of readings indicated that the
controller and PC were less than
100ms apart
– 93% of readings indicated that the

Supports for Features Planned for V16
• Supports Universal Coordinated Time
(UTC) (Formerly known as GMT).
• Sets Time Zone and Daylight Savings
Time based on the user’s PC settings
• Requirements
– Device to be synchronized and PC must
reside in the same time zone.
– Requires V16 or higher Firmware for new
features. Devices with pre-V16 firmware
will store the local time, ignoring the time
zone and daylight saving time.
• Note: Users should avoid setting the Time
Zone or Daylight Savings Time from RSLogix
5000, as any changes will be overwritten
during the next synchronization.
