5 Logging Groups
A logging group is a set of application property inputs and
outputs whose value are recorded (logged) with the same
parameters. Parameters include the interval, how often the
property values are logged (for example, every 30 seconds,
every 5 minutes, etc.), the duration of the log (for example, 2
days, 30 days, 100 days, etc.), and the resolutions (how
precisely the analog values are recorded). Individual logging
groups can be configured to archive data to an SD card if
desired.
5.1 Supported Functions
1. Viewing log parameters.
2. Adding new logging groups.
3. Editing parameters of existing logging groups.
4. Deleting logging groups.
Select View & Edit to view, edit, or delete logging groups.
The Points List appears on the right-hand side of the screen
showing all the points logged in the system.
5.2 Data Logging Types
The system handles the following types of data logging:
Base Log - Takes the measurements from all data points
associated with the log group at a fixed frequency over a
defined period of time. The measurements are time-bound
stored in an internal non-volatile memory. The system will
support a maximum of 1000 digital points or 750 analog
points to be logged at a 15 minute interval for a maximum of
365 days.
Utility Log
- Takes the measurements from all data points
associated with the utility logging group at a frequency
defined by the application to which each data point belongs.
A logging group configured as Utility can contain multiple
points logged at different intervals. Applications which
contain data points supporting utility logging are Global Data
(Heating/Cooling/Enthalpy degree-day outputs) and Utility
Monitoring (all totalizer outputs). All of these data points are
automatically associated with the Util Base Log default
logging group.
5.3 Logging Group Functions
Create New Group
Create logging groups and configure settings for logging
groups. On this screen, the user can view, edit, and delete
logging groups.
Name
The name assigned to this instance of a log group.
Mode
The logging mode is one of the following: Continuous or
Utility.
• Continuous Mode - Logs occur at regular intervals
determined by the Log Interval.
• Utility Mode - Allows individual applications (device
representations or other) to log (save) samples at
arbitrary (non-periodic) time stamps. This is used by
applications that need to be in control when exactly a
sample is written and the value is cleared, reset or other
action taken. (The default setting is Continuous.)
Log Interval
The rate (every 15 seconds) or amount of time between log
samples or measurement. The user configurable range for
this property is 15 seconds to 12 hours in 5 second
increments. The default setting is
00:03:00 (3 minutes).
Log Duration
Specifies the number of whole days of logging that is kept for
each point associated with this logging group. The default
setting is 14 days.
Log Total Samples
This parameter is only available for logging groups
configured as Utility. It specifies the maximum number of
measurement samples for the utility logging group to store in
memory. Once the maximum number of samples has been
logged, each new sample will overwrite the oldest sample in
the log.
