My Problem is how to execute in Python the test script which contains the I/O-Actions.
You shouldn't execute a test script from the Python code of another test script. The normal use case would be to use Call or RemoteCall to execute the other test script and the test report of the other one is integrated in the original one. But you need a loop which is not implemented yet.
Are you using the commands from TestManager.Monitoring in that test script? If yes, than you could do the same by using the scripting interface. See read_value(), set_prepared_value(), write_prepared_values() and other methods of the IScriptOnlineApplication.
