Abstract: A processor platform (HW) of a processor-controlled facility (PC) is configured such that independent partitions (P1, P2) can be set up, with an operating system (OS1, OS2) being assigned to a partition (P1, P2) and at least one application (APP(OF,TEL)) being assigned to said operating system (OS1, OS2). The functional scope of the respective operating system (OS1, OS2) is optimized for the respective at least one application (APP(OF,TEL)). By using a common processor platform (HW) and optimizing the operating systems (OS1, OS2) to the requirements of the respective application (APP(OF,TEL)), it is possible to achieve a particularly economical realization, with only those applications necessary for the operation of the respective application (APP(OF,TEL)) being realized in the operating system (OS1, OS2). The independent nature of the partitions (P1, P2) means that the applications (APP(OF,TEL)) are highly available compared with the known software solution for applications.
