Trend Logging Interval
In the Trend Logging Interval Window (Figure 93) located in the
Miscellaneous Settings Screen (Figure 85, page 40), you can
confi gure how often you want the GPC-XP to log the Input and
Output values and conditions by entering a Logging Interval and
press
<ENTER> to save. The maximum amount of time that can be
entered is 60 minutes.
The GPC-XP will store up to 120 trend instances in its on-board
memory. So, if you are Trend Logging every minute, you will al-
ways have the latest 120 minutes worth of trend logging saved in
the controller.

Logs over a longer period of time (beyond the 120 on-board) you
can confi gure Prism 2 to download the Trend Logs your computer
hard drive at multiple intervals during the day. See the Auto Log-

Figure 92: Daylight Savings
Daylight Savings Time
In the Daylight Savings Time Window (Figure 92 below) located in the
GPC-XP Miscellaneous Setpoints Screen (Figure 85, page 40), if you
want the Schedules on this GPC-XP to respond to Daylight Savings
Time changes, you must enter the Start and End dates in this fi eld.
Daylight Savings Starting Day
This is the date in the Spring when the time clock automatically ad-
justs itself forward one hour. If you are in a time zone that does not
have daylight savings time or do not want to use this feature, leave
this value at zero. High limit = 1231; Low limit = 0; Default = 0.
NOTE: The U.S. government has the authority to determine
the switch-over dates each year. Currently, the time
changes the second Sunday in March and then
switches back the fi rst Sunday in November.
Daylight Savings Ending Day
This is the date in the Fall when the time clock automatically adjusts
itself backward one hour. If you are in a time zone that does not
have daylight savings time or do not want to use this feature, leave
this value as zero. High limit = 1231; Low limit = 0; Default = 0.
