Simple, but Flexible!

Step 1: Machine Parts, the Visual

Using standard controls, or graphics from the machine parts collection, design your own IAG.

Add interface properties and methods to bring the object to life when reused.

Step 2: Extensible with Visual Basic

As well as many graphic IAGs, it is also possible to

embed code within an IAG. The code can extend

the possibilities of the gadget such as providing

special device communication. Thanks to

Visual Basic the standard functionality of the NA

can be extended as required.

myTemperature

mySpeed

RunMotor(Boolean bStatus)

‘IAG Code behind - Add local subroutines for the IAG.

Public Function RunMotor(bStatus As Boolean) As Double

‘start motor at default speed

mySpeed = 50

‘return current speed

RunMotor = 50

End Function

Public Function IncreaseSpeed(nIncrement As Integer) As Double

‘ Increase speed by increment if < 1000

If mySpeed + nIncrement

< 1000 Then

mySpeed = mySpeed + nIncrement

Else

‘Otherwise set to top speed

mySpeed = 1000

End If

‘Return new speed

IncreaseSpeed = mySpeed

End Function

The NA Series gives the user the ability to design using IAGs (Intelligent Application Gadgets). IAGs simplify and

accelerate the development process through structuring the project and enhancing reuse. From simple graphics

to complex objects, you can make your own collections and share them between projects, like a Function Block.
