• AlarmControl
• FunctionTrendControl
• OnlineTableControl
• OnlineTrendControl

Scripting:

The main point here is to use “ToolbarButtonClick” property.

This property needs a reference number to work (ID).

The referencing of a button with its ID does not depend on the actual order of the buttons. The

ID are listed in the inspector window of the object under "Properties > Properties > Toolbar >

Toolbar - Buttons".

Example:

This script simulate a click on button “Select Trend” (16) of the object "f(t) trend view_1":

Sub OnClick(ByVal item)

Dim aaa

Set aaa = HMIRuntime.ActiveScreen.ScreenItems("f(t) trend view_1")

aaa.ToolbarButtonClick=16
