Types of Archiving
There are two types of archiving: Status and Time Based Archiving. The Enabling/Disabling
of each type will give the user a different set of archives.
Status Archiving
When Enabled, each time a channel status event occurs, a time stamped archive event will be
recorded into the dialer’s memory. These events include a state change (open to closed), an
alarm status change (from out of alarm to into alarm), and an acknowledgement of an alarm.
This is a useful type of archiving when all the operator is concerned with is finding out when
certain events occur. For example, finding out when and how long a pump motor has run, or
determining when and how often a tank is being filled/emptied.
Time Archiving
When Enabled, a channel’s status events will be recorded at some time interval (See Archive
Interval below). Two types of events will be recorded: First Time Archive and subsequent Time
Archives. The First Time Event shows when the channel first started recording the information for
the channel using Time Archiving. Each subsequent Time Event tells when the next Time Based
Archive was taken.
This is useful when monitoring a tank level, temperature, flow rate, or anything that is measured with
a 4-20mA signal, 0-5v AC signal, etc. For example, recording a tank level every 5 to 15 minutes and
determining how fast it fills/empties.
Archive Interval: Days:Hours:Minutes
Used as the time frame for Time Archiving. This interval is the rate at which the Time
Archiving will take place. When Time Archiving is first setup, this time interval will be used to
determine when the First Time Archive will take place. The dialer will try and make each
archive based on the top of a minute. Also, if the time interval is some multiple of an hour, it will
setup the archives to a time frame that will record archives using this association.
Okay…What was just said? If the interval is 15 minutes and the current time is 9:35, it will
record its first Archive at 9:45, then 10:00, 10:15, 10:30, etc. If the interval is 30 minutes and
the current time is 9:35, it will record its first Archive at 10:00, then 10:30, 11:00, 11:30, etc.
If the interval is 6 minutes and the current time is 9:35, it will record its first Archive at 9:36,
then 9:42, 9:48, 9:54, 10:00, etc.
If the time interval is not a multiple of an hour, it will determine the best time to start recording
and go from there.
To Edit the Archive Interval, click on the small button to the right of the desired channel’s current
Archive Interval. Change the interval to the desired number of days, hours, and minutes. To
change all channel’s Archive Time Intervals, select the Change All before clicking OK.
