Specifying Property Element Attributes

The following table lists the attributes of a Property node in alphabetical order. The

table gives a brief description of the property and lists which properties are required and

which are optional.

Attribute Description Required

constraint Specifies the constraints on the property —

see “Specifying Values for the Constraint

Attribute” on page 7-14.

Required

default Default value for the property. Optional

deviceSpecific Boolean value. True if property is vendor-

specific; otherwise false.

Required

min Minimum allowable value Optional

max Maximum allowable value Optional

name Name of property Required

optional If set to off, the property is created

automatically and added to the object

when the IMDF file is processed. If on, the

adaptor must explicitly create the property.

The default is off.

Optional

readOnly Read-only status of property: always,

never, or whileRunning.

Required

type Data type of the property: cell, double,

int or string.

Required

Specifying Values for the Constraint Attribute

Constraints specify information about what are valid values for a property. For example,

to specify that a property only accepts positive values, use the positive constraint value,

as follows:

constraint=positive

The following table lists all the possible values for the constraint attribute in

alphabetical order.
