5 Time synchronization

In the Entellisys System, time is recorded when events occur for diagnostic purposes. Events are generated from both the HMI and the CPU components and the time stamps used are derived from time set in the component.

One HMI in the system will be configured to synchronize time with the CPUs. Periodically, the

HMI will synchronize time to ensure the time in the two CPUs is consistent.

Time synchronization configuration is done by GE during the system start up.

NOTE: The System Administrator should periodically check the date and time set on all local HMIs to ensure the event time stamps are accurate. It is especially important on the HMI configured to time synch the CPUs.

5.0.1 Setting time in the HMI

To set time, log into the HMI Operating System with Administrator access (see Administrator access to the operating system on page 61.) Double-click the Clock icon on the taskbar to set date, time, and time zone. Restart the computer to revert to normal run mode with limited OS access.
