System Startup History
Figure 17. System Startup History Screen.
The control keeps track of the times when the system stops running and starts running.
The most recent system down/system up events are reflected in a table kept in the memory
of the control. The table has eight slots and is sorted in ascending chronological order.
There are two columns:
System Down Time
Time when power to the control was lost. Note that in the case when the system started
up as a result of an application download this item is going to be empty.
NOTE: this time is approximate, with the precision of about half a second.
System Up Time
Time when power to the control was restored or the application was downloaded. The
System Down Time in the same row subtracted from this value equals the amount of time
the system was not running.
