Echelon OpenLNS - Manual (Page 628)

OpenLNS Programmer's Reference 591
OpenLNS uses the value of the
Measurement System field (either
U.S. or metric) on this tab to
determine the default format to use
for types such as SNVT_temp_f.
You can also specify a full format
name (i.e. SNVT_temp_f#SI for or
SNVT_temp_f#US)
to select a
specific format for that type. For
UNVTs, you must always specify a
fully-qualified format name.
2. In some cases, a format exists for a
given SNVT or UNVT that has the
same name as the underlying type.
This is called the root format for the
type, and it may be different from
the default format for that type. In
order to explicitly use the root
format, you will need to append a ‘#’
character to the format name you
write to this property to indicate
that you are specifying the format
name (and not the type name) for
this type.
For example, if you read the value
of a network variable of type
SNVT_time_stamp when the
CategoryPreferenceList property of
the FormatLocale object your
application is using is set to LO,
and you set the DsFormatType
property to SNVT_time_stamp, then
the data stored in the Value
property will be formatted using the
SNVT_time_stamp #LO format.
However, if you set the
DsFormatType property to
SNVT_time_stamp#, the data
stored in the Value property will be
formatted using the root
SNVT_time_stamp format.
3. A fully-qualified format name,
expressed in the following syntax:
"#[].name>
"
In this syntax, the "#", "[", "]" and
"." characters are literal characters.
A hex byte string represents the
program ID. The scope is a
one-digit string. It represents a
filter that indicates relevant parts
