Property Description

#<manufacturer ID>[scope selector].<type name>[#format] .

This determines many factors about the Virtual data point,

including the type of values it takes and its base type. If you do

not set this property, it is set to RAW_HEX and the Virtual data

point uses raw hex values.

Specifies the size (in bytes) of the Virtual data point.

Specifies whether the Modbus data point is an input data point

(DIR_IN), output data point (DIR_OUT), or undefined

(DIR_NUL).

The handle assigned to the Virtual data point assigned by the

SmartServer. When you use the Set function to modify the

configuration of an existing Virtual data point, you must specify

the data point’s handle. If you do not specify the handle, a new

Virtual device is created. You cannot use the Set function to

modify the handle assigned to the Virtual data point.

The frequency in which the SmartServer’s internal data server

polls the Virtual data point. The recommended minimum poll

rate is 30 seconds; the maximum poll rate is 1 second.

Polling for Virtual data points is disabled (0 seconds) by default.

Note: The actual poll rate is determined by calculating the least

common denominator of all the poll rates set for the data point

from the applications to which it has been added.

17.4.3

Using the Set Function on Virtual Data Points

You can use the Set function to overwrite the configuration of a Virtual data point, or to create a new

Virtual data point. The input parameters you supply to the function will include one or more <Item>

elements. Each <Item> element includes a <UCPTname> property that specifies a unique Virtual data

point to be created or modified.

Each <Item> element may also include a series of properties that define the configuration of the new

(or modified) Virtual data point. This set of properties is the same whether you are creating a new

Virtual data point or modifying an existing Virtual data point.

• If you are creating a new Virtual data point, you should specify the <UCPTformatDescription>

property; all other properties are optional.

• If you are modifying an existing Virtual data point, you must specify the <UCPThandle> property.

In addition, all other properties should be filled; otherwise the values stored in them are erased.

The previous section,

Using the Get Function on Virtual Data Points, details the properties you

can include in the Set function.

You can set multiple Virtual data points with a single Set message. However, you should not attempt

to create or write to more than 100 Virtual data points with a single call to the Set function. The

following example demonstrates how to create a new Virtual data point.
