OpenLNS Programmer's Reference 363
FormatType property is set to lcaFormatTypeNamed (0).
In that case, the Scope and ProgramId properties are used to
identify the resource file containing the type’s definition.
The way that OpenLNS determines the default value for this
property, and the syntax you can use when writing to this
property, varies depending on the type of object to which the
FormatSpec applies:
•
NvMonitorPoint object or a DataPoint object that
represents a network variable using a standard type.
The FormatType property will be initially set to
lcaFormatTypeNv (1), and this property will have no
effect. However, you can still set the FormatType
property to lcaFormatTypeNamed (0) and then write
to the FormatName property using the same syntaxes
you would use when setting a NetworkVariable object’s
DsFormatType property.
• DataPoint object that represents a network variable
using a user-defined type.
The FormatType property will be initially set to
lcaFormatTypeNamed (0), and the FormatName
property will default to the TypeName assigned to the
DataPoint object. In this case, you can also write to the
FormatName property using the same syntaxes you
would use to write to a NetworkVariable object’s
DsFormatType property. See the DsFormatType property
for more information.
• DataPoint object that represents a configuration
property.
The FormatType property will be initially set to
lcaFormatTypeNamed (0), and the FormatName
property will default to the TypeName assigned to the
DataPoint object. You can write to the FormatName
property using the same syntaxes you would use to write
to a ConfigProperty object’s FormatName property.
OpenLNS will determine the default value for the
property in the same manner, as well. Consult the online
help for the FormatName property of the ConfigProperty
object for more information on this.
Note: FormatSpec objects are not passed by reference. If you
modify the values assigned to the properties of a FormatSpec
object, you must then explicitly assign the FormatSpec object
back to the FormatSpec property of the NvMonitorPoint or
DataPoint for the changes to take effect.
Availability Local, full, lightweight, and independent clients. Note that
some objects containing this property are not available to
Independent clients.
