20.3.3

Reading and Writing Data Point Values in Visual Basic .NET 3.5

The following Visual Basic .NET 3.5 example reads the value of the Net/LON/iLON App/Digital

Output 1/nviClaValue_1 data point on the SmartServer, and then writes a value of “100.0 1” to it. This

SNVT_switch data point is one of the relay outputs on the SmartServer. You can execute this code

after you have completed section 20.1.1,

Referencing and Inheriting from the WSDL Using .NET 3.5

Framework, and section 20.2.3,

Instantiating the Web Service Client in Visual Basic .NET 3.5.
