SmartServer 2.2 User’s Guide 265
You can change the default presets for a given data type by modifying its
template in the /config/template/lonworks/dp folder on the SmartServer
flash disk. For example, you could change the default presets for the
SNVT_switch data type by modifying the
/config/template/lonworks/dp/#0000000000000000.SNVT_switch.xml
file.
Fields Structured data points (data points with multiple fields) such as
SNVT_switch, SNVT_alarm, and SCPT_maxRcvT have default names
and unit strings describing each field that are defined by resource files.
You can edit the default names and unit strings.
Using a SNVT_swtich data point for example, the data point will have
fields named by default “Value” and “State” with unit strings of “% of full
level” and “state code”, respectively. You could change the unit string
used to describe the “State” field from the default “state code” to
“occupied” for a restroom occupancy sensor
To edit the unit strings of the fields within a structured data point on an
internal SmartServer device, click Add Unit to open the Select Fields
dialog. Click the field with the unit string to be edited and then click OK
to return to the Configure - Data Point Web Page, and then click Submit.
The selected field is added under the Fields property at the bottom of the
Configure - Data Point Web Page. You can then enter a brief description
of the unit string to be used for that field in the Unit String box.
To edit the unit strings of the fields within a structured data point on an
external device, enter a brief description of the units to be used for that
field in the Unit String box.
To reset the unit string used by a field to its default, click the field and
then click Delete Unit.
