3.6 Using the DataPoint Functions With Visual Basic .NET
You can call the DataPoint functions from development environments such as Microsoft
Visual Basic .NET by referencing the
i. LON 100 WSDL file. Chapter 14, Using the SOAP
Interface as a Web Service, describes how to reference the i. LON 100 WSDL file in Microsoft
Visual Basic .NET.
This chapter describes the syntax you will use when you call each of these functions, and
provides a code sample written in Visual Basic .NET that invokes each of them.
3.6.1 DataPointWrite
Syntax: return=ilonWebReference.DataPointWrite(UCPTpointName As
String, UCPTfieldName As String, UCPTvalue As String, UCPTpropagate
As Integer, UCPTpriority As Integer)
Element Description
return DataPointWriteReturnType variable
ilonWebReference Instance of the i. LON 100 WSDL file Web service.
Input Parameters For descriptions of the individual input parameters
that you must supply to the function, see
DataPointWrite on page 3-3.
Returns: The function returns an object containing two properties: the name of the data
point written to (UCPTpointName), and the name of the field written to (UCPTfieldName).
3.6.2 DataPointRead
Syntax: return=ilonWebReference.DataPointRead(UCPTpointName As String,
UCPTfieldName As String)
Element Description
return DataPointReadReturnType variable
ilonWebReference Instance of the i. LON 100 WSDL file Web service.
Input Parameters For descriptions of the input parameters that you
must supply to the function, see DataPointRead on
page 3-7.
Returns: The function returns an object containing each of the properties described in Table
5 on page 3-7. Each property can be retrieved from this object individually by referencing the
property name listed in Table 5, as shown in the programming sample later in this section.
3.6.3 DataPointResetPriority
Syntax: return=ilonWebReference.DataPointResetPriority(UCPTpointName
As String, UCPTpriority As Integer)
Element Description
return String variable
ilonWebReference Instance of the i. LON 100 WSDL file Web service.
