Communications software PROFIBUS Master for Intel FPGA

portable protocolFPGAhigh-performance

Integration of PROFIBUS DP into Industrial Controllers using Intel (Altera) FPGA The PROFIBUS DP Master IP Core integrates components required for implementing a complete PROFIBUS DP Class1 and Class2 Master based on FPGA technology. Thus, no specific fieldbus controller ASIC is needed in addition. Minimum Development Effort • Combination of all components required for implementing a PROFIBUS DP Class 1 or Class 2 Master into a Field Programmable Gate Array (FPGA) • PROFIBUS DP bus control logic available as loadable IP Core • PROFIBUS DP protocol stack ready to be used on soft core processor within FPGA • Control application running on second processor inside the FPGA or on separate external host processor • Including PROFIBUS DP versions DP (exchange of cyclic data and diagnosis with slaves), DP-V1 (acyclic data exchange and alarm handling) as well as DP-V2 (clock synchronization and time-stamping) Flexibility Through Integrated Fieldbus Controller • Provision of complete bus control logic for accessing PROFIBUS DP network • Handling of all time-critical parts of PROFIBUS DP Data Link Layer, token handling and cyclic data exchange • No dependency on fieldbus controller ASIC and its vendor Improved Plant Availability • Support of Master redundancy providing seamless switchover from primary to backup PROFIBUS DP Master • Optional line redundancy functionality for accessing field devices via redundant fieldbus cables • Support of re-configuring individual PROFIBUS slaves without shutting-down plan
