5.1.3.9 Moving Average
The Moving Average (sometimes referred to as the Rolling Average) is a special instance of a calculated
channel. It calculates the average of the input value over a user set period of time known as the Moving
Average Interval. The average is maintained over this period on an ongoing basis until reset. If the
interval is set at 1 hour then the value displayed is always the average of the last (or most current) 1 hour.
The sample interval for the average is always 1 minute, so in the case of a Moving Average Interval of 1
hour the value will be the average of the most recent
60 samples.
Select a Channel Type of Moving Avg. This will bring
up the Moving Average dialog window.
Ext. Reset Enable: This is the External Reset. If
this box is checked the count will be reset by an
external event via the digital inputs
Note: an
optional digital I/O card must be present in the
system AND the designated input must be
programmed as a count reset for this to work.
Ext Input: This indicates which external digital
input will reset the Moving Average when Ext.
Reset Enable above is checked and the digital
input is
enabled . The digital input needs to be
programmed as a Count Reset type.
Moving Avg Intvl: This is the average time period in days, hours and minutes over which the average
is calculated. Note that the Sample interval defaults to 1 minute so a 1 hour moving average interval will
contain 60 samples, a 1 day interval will contain 1440 samples.
Reset Sync: If the Sync Enabled checkbox is checked the Count will reset the first time it reaches
the set time. This allows the user to synchronize the reset to a known time. This also allows several
channels to be synchronized together if the Reset Sync time is set to the same for all. This time is
ignored if the enable box is not checked.
Reset Print: When this box is checked each time the total is reset, the information will be appended to
the alarm/event log (time and total).
Power Up Reset: If checked the average will be reset when the unit is powered up otherwise it will
carry on from where it left off when the unit was powered down
Base Point: This is the actual source for the average. The channel selected
from the drop down menu should be set up for the correct input and in the
correct units.
Sample Intvl: This is the sample interval (not the average interval). It is defaulted to 1 minute and
cannot be changed.
Apply: Save the values and exit Cancel: Exit without making any changes
