Silent Mode

Sometimes an Automation Interface script or program should operate silently, which means without any message boxes or other visible interruptions. Although the Visual Studio DTE command “dte.Visible = true/false” may seem sufficient in most use cases, the TwinCAT Automation Interface introduces a new Silent Mode switch, which is available since TwinCAT 3.1 Build 4020.0 and above.

This new switch can be activated as follows.

Code snippet (C#):

var settings = dte.GetObject("TcAutomationSettings");

settings.SilentMode = true;

Code snippet (Powershell):

$settings = $dte.GetObject("TcAutomationSettings")

$settings.SilentMode = $true

This will suppress message box dialogs during usage of the TwinCAT Automation Interface.
