How to set Parameters in Scheduled Tasks wtih Powershell

Hi,

how can i set a Parameter for a Scheduled Task in ARS 6.5 with Powershell?

I added the parameters on the scheduled Task.

In the SDK is only a VBS HowTo (Topic "Specifying Parameters for Scheduled Tasks").

I tried it on different ways in Powershell:
---
$Task = Get-QADObject "<Scheduled Task>"
$Task.Parameters("NewName") = "Test123"
Error ParameterizedPropertyAssignmentFailed
---
$Task = Get-QADObject "<Scheduled Task>"
$Task.Put("NewName, "test123")
Error MethodNotFound
---

Regards
