Component-Based Software Engineering has been introduced as a technique for the development of complex systems. Software complexity can also be reduced by partitioning the system behavior into different modes. Such a multi-mode system is able to change its behavior at runtime by switching between different operational modes. When a multimode system is developed by reusable software components, a crucial issue is how to achieve a seamless composition of multi-mode components and also how to handle mode switch properly. This is the motivation for the Mode Switch Logic (MSL), supporting the development of component-based multi-mode systems by providing mechanisms for mode switch handling. In this report, MSL is extended and adapted to systems with emergency triggering of mode switches that must be handled with minimal delay. We propose an approach, called Immediate Handling with Buffering (IHB), to enable the responsive handling of such an emergency event in the presence of other concurrent non-emergency mode switch events. We present a model checking based verification of the IHB approach, and illustrate its benefits by a small example.
