The method relates to the location-independent exchange of process data between application programs (5) and process management systems (4). The process management systems (4) and the application programs (5) are provided in a number of different process computers systems (2.1 to 2.7) which are interconnected via a network (1). The data exchange takes place by using a software system (3) which is called Process Information Broker PIB (3) and has three types of component, namely PIB server (3.1), PIB client (3.2) and PIB services (3.3). The PIB services (3.3) contain a switching service (3.31) and a user administrator (3.32). During the start-up of the system and for the purpose of updating, in the respective computer system (2.1 to 2.7), process data are converted from process-computer-specific data structures into process-computer-independent data structures, typified and provided as stored data in an interface. All the computer systems (2.1 to 2.7) register the process data types provided by them, including the storage location thereof, with the switching service (3.31). The stored process data are accessed by the application programs (5) by involving the switching service (3.31) in order to ask for the offered process data types and their storage location. On this basis, process data types are retrieved and operations executed.
