Method for reading and/or writing characteristics or parameters of an installation device connected to a bus system

摘要

The method involves implementing a characteristic object service (22) in an operating system of an installation device (1), where the service reads or writes the installation device's characteristics/parameters e.g. values (7) of a communication object (2). A characteristics object (8) is created for the communication object, and is connected with a storage unit (21). The object values are received and written into a storage position in the storage unit based on entry in the characteristics object. A flag (6) is set for controlling access to the values of the communication object.
