Martinez Lastra A new concept for distributed control systems based on the new IEC 61499 standard is tested in this work in cooperation with LAE Engineering GmbH a medium-sized company. Based on a catalogue of requirements a customer-related testbed is developed. In the following this testbed is used as a reference to realise an IEC 61499 compliant-distributed control system based on PC technics. By doing this rules are defined to convert user-owned IEC 61131 function blocks to IEC 61499 compliant function blocks. Concluding some trends for IEC 61499-based distributed control systems will be summarised. Copyright 2008 Christian Gerber et al.

THE PROBLEM Especially for medium-sized companies it will become more and more important to create solutions of automation problems that are optimally coordinated with the customer in order to maintain the competitiveness also in future. Thereby these medium-sized companies can feature themselves by manufacturerer independence and usage of the hardware that the customer prefers which maybe replaced in only some cases by better matching components. It is also possible in smaller projects to use hardware that .
