Implementation of a Profibus agent for the Proview process control system

Sammanfattning: Proview is an open source system for process control, developed at SSAB Oxelösund. A wide range of IO systems are already supported by Proview. This thesis documents the implementation of support for the Profibus DP master board Hilscher CIF 50-PB. Most of the features of the board are supported by the agent. The agent is intended to support up to four boards per system. Adding support for additional types of Profibus DP master boards from Hilscher to the agent should be straightforward. This thesis covers some technical aspects of the Profibus DP technology and also provides some background of Proview’s IO system. The design decisions behind the Hilscher agent implementation will be discussed. All functions and data structures of the implementation are documented. Testing of the implementation is also included in the thesis. The thesis may also be used as technical documentation for the agent implementation. Finally, we look at the strengths and shortcomings of the completed agent implementation.
