Based on the complex grid infrastructure of the Ilmenau Interactive Hybrid Online Lab various possibilities of occurrence of malfunctions as well as mechanisms to avoid them will be discussed. This will be demonstrated by different examples. One implementation challenge is to protect the physical systems in the lab against wrong control algorithms or malicious trying to sabotage or to destroy the system - without defining too many design constraints. Therefore, a high level of safety must be guaranteed for such an autonomous working system. Therefore the first step is the verification of sensor and actuator constellations to guarantee safety in online labs. Based upon this an efficient possibility for a validation of the studenta€?s design will be shown as subsequent step.
