Syntax index = object.Index
Element Description
object The object to be acted on.
index Index of the network variable. The
valid values for this element are 0–14.
Data Type Integer.
Read/Write Read only.
Added to API Prior to LNS Release 3.0.
IsConfigProperty
Summary Indicates whether the network variable implements a
configuration property that conforms to the LonMark
interoperability guidelines.
A True value indicates that the network variable implements
a configuration property conforming to LonMark
interoperability guidelines. The related ConfigClassFlag
property will be set to True whenever the IsConfigProperty
property is set to True. However, as described below, some
network variables may have the ConfigClassFlag property
set to True, and still have the IsConfigProperty property set
to False.
Currently, there are two ways in which a device developer
can implement a configuration property as a network
variable:
1. Use the "config_prop" or "cp" keywords, which is the
recommended, newer method. This method automatically
creates a configuration network variable (CPNV) with an
appropriate SelfDocumentation string that specifies the
configuration property attributes. See the NodeBuilder
User’s Guide for more information on the "config_prop"
or "cp" keywords.
2. Use the "config" keyword. Any network variable
declared with the "config" keyword will have a
ConfigClassFlag value of True. However, in order to
implement a configuration property (and therefore have
the IsConfigProperty set to True), you must manually
provide a LonMark compliant SelfDocumentation string
that specify the attributes of the configuration property.
See the NodeBuilder User’s Guide for more information
on the "config" keyword.
