Abstract
A communication system and, method are therefor, are provided. The system includes a control circuit which includes a message-based operating system and application software. The system also includes a device and/or software for exchanging/replacing application software. When a portion of the application software is to be exchanged, an old software component to be exchanged carries out a state transfer, stops at a certain point, and directs available messages to a new software component. The software components include an application thread and an exchange thread. The old software component gathers its state after the application thread has stopped at an exchange point. The exchange thread then transmits the state through an exchange port to the new software component.
