5. DATA FILE FORMATS
5.1. Sensor File
The SENSOR FILE describes sensors with their
group assignments, specifies their temperature
thresholds, and stores their EPC codes once
assigned. The SENSOR FILE is in comma-sepa-
rated-value (CSV) format and can be created in
a text editor or spreadsheet application. The
following rules apply to the SENSOR FILE:
• Lines beginning with a # character are
considered comment lines and are ignored.
• Blank lines are allowed and can be insert-
ed along with comment lines for readability.
• All other lines describe a single sensor
and must have either 5 or 6 fields, each sep
-
arated by a single comma. From left to right,
the fields are (1) the sensor group ID code,
(2) the group description, (3) the sensor
location, (4) the run temperature threshold,
(5) the restart temperature threshold, and
(6) the EPC code of the sensor. The EPC field
is populated only after a sensor has been
installed and assigned.
• If an EPC has not yet been assigned to a
sensor, the trailing comma after the restart
threshold is optional.
• Commas can not be used inside individual
fields.
• The group ID code must be between one
and four alphanumeric characters. All sensors
with the same group code will be placed in
the same group.
• A group description of one or more alpha-
numeric characters must be specified for at
least one of the sensors in each group. The
group description can be left blank for other
sensors in the group. If specified more than
once for a group, the multiple specifications
for a group must be identical.
• The sensor location must be at least one
alphanumeric character in length. Location
descriptions do not need to be unique, but it
is recommended that they be unique within
their group.
• The run threshold must be a numerical
value.
• The restart threshold must be a numerical
value.
• To define the units of the Run and Restart
thresholds, add to the beginning of the file
the line “[THRESHOLD_UNIT],C” for Celsius
or “[THRESHOLD_UNIT],F” for Fahrenheit.
Units will default to Celsius if no unit is de-
fined.
NOTE: If Run and Restart alarms don’t apply
to your application, feel free to treat these
as two independent alarm thresholds.
• The EPC field is not filled in by the user
when creating the Sensor File. When a sensor
is installed and assigned, the software writes
the EPC code of the assigned sensor into this
field. It should not be modified unless the
sensor is to be removed and replaced. In that
case, the EPC field can be deleted and a new
sensor can be reassigned using the normal
installation process.
