Embedded EL + reasoning on programmable logic controllers

Many industrial use cases, such as machine diagnostics, can benefit from embedded reasoning, the task of running knowledge-based reasoning techniques on embedded controllers as widely used in industrial automation. However, due to the memory and CPU restrictions of embedded devices like programmable logic controllers (PLCs), state-ofthe- art reasoning tools and methods cannot be easily migrated to industrial automation environments. In this paper, we describe an approach to porting lightweight OWL 2 EL reasoning to a PLC platform to run in an industrial automation environment. We report on initial runtime experiments carried out on a prototypical implementation of a PLC-based

Agent technology has the potential to play a key role in building and supporting virtual enterprises. To host and enable agents an open infrastructure is needed. Beside standards, such an infrastructure should be generic and deployment independent to deal with the heterogeneity of the computing and information technology, e.g. by supporting devices like mobile phones, PDAs and personal computers as well as different kinds of mobile and fixed networks. We give an overview over the agent platform LEAP, developed for small end user devices. We show the main issues in downsizing it to PDAs/mobile phones and applying agent technology in the area of virtual team support.
