Tyco Electronics Galaxy SC Controller J85501F-1
Issue 13 February 2001 Feature Descriptions 7 - 56
Daily Statistics: Daily maximum and minimum values for the day of a
power failure will be the high and low readings between the time power
was restored and the next change of day.
The daily maximum one-hour average will be the highest average
recorded since power was restored. If multiple power failures occur
during the day, only readings taken between the last power restoration
and the change of day will be used.
Effect of Changing
Date and Time
In general, statistics logs will not be affected by clock changes unless
they are in the process of being recorded when the change is made. Even
then, changes are similar to those experienced in a power failure, and
proper logging will resume at the next change of hour or day. Where the
change results in an incomplete entry, no data will be displayed for that
period.
Effect of Changing
Scale Factor,
Range or Channel
Type
Changes plant shunt, rectifier shunt, derived channel program line or
remote peripheral scale factor will make the trend study invalid because
large changes are possible out of range readings. Trend and basic
statistics associated with the channel will be cleared and the first new
entry will begin at the next minute.
Terminal Menu
Interface
All Galaxy controller software includes a text based menu interface
that can be used to check most of the system’s status, history, and
statistics functions, using a standard ASCII type terminal. Refer to
Appendix E for complete description.
Timer Events Timer Events is a feature available on the Intelligent Galaxy SC only.
The main purpose of Timer Event is to generate a binary signal at a
specified time and date that will persist for the duration that you
configure. This binary signal can be used in the User Defined Events
program line to generate time based alarms. There are 32 Timer Events
available in the system. You can specify start date, start time, and
duration in minutes range from 1 minute to 24 hours. The default start
date is daily, the default start time is midnight, and the default duration
is forever. The value for default date is 00/00/0000, (mm/dd/yyyy); the
value for default duration is 0. Setting any portion of the date to 0 causes
that value to be ignored when deciding if the Timer Event is active. For
instance, a Timer Event with a date of 00/01/0000 will occur on the first
of every month. Timer Events parameters with invalid values will be
rejected and the changes will not be made. If any change is made to the
start date, start time, duration, or the system data and time, the system
