Effective solutions for asset management become increasingly important in modern automation and control systems. They are especially required in the area of process control. The control systems used here usually consist of PLC-based networks, which are optimised concerning the special temporal and topological requirements of the process. Asset management functions have to be introduced to those systems, without any influence on the existing equipment. The paper shows an object-oriented solution based on PROFIBUS-PA device. By automatically evaluating a system structure and mapping the profile-relevant parameters of devices to proxy objects, different application modules for asset management functions can be implemented acting on these objects.
