support changeable types, then the value of the MaxLength
property will always match the value of the Length property.
You can determine if a network variable supports changeable
types by reading the network variable’s
ChangeableTypeSupport property.
If the device supports changeable types, and the
configuration properties are avaliable, then this property will
be set to the maximum network variable length as defined by
SCPTmaxNvLength configuration property reported by the
device for that network variable. In this case, reading this
property is the same as reading that configuration property
directly. It may result in an attempt to read the value from
the device, if the configuration property value is unknown to
OpenLNS.
You can determine if the configuration properties for a device
are available by reading the ConfigPropertiesAvailable
property of the Interface object used by the device. If the
network variable supports changeable types and the
configuration properties are not available, or the device does
not contain a SCPTmaxNvLength configuration property
for the network variable, this property will be set to –1.
Availability Local, full, and lightweight clients.
