Design and Implementation of PROFIBUS DPV0 Master Software

PROFIBUS is an international and open fieldbus standard and is widely used in manufacturing automation, process industry automation and building, transportation and power automation and other fields. PROFIBUS DP master is the core part of PROFIBUS control system. At present, domestic main solutions for DP master are mostly provided by foreign manufacturers, including pure software, ASIC chips and embedded main modules, etc. The disadvantages of these solutions are high cost and supply cycle. Based on the fieldbus international standard IEC61158-Type3, this paper introduces the design and implementation of a DPV0 master protocol software. At the same time, a DPV0 master prototype is developed on the STM32F407 microprocessor platform, and a test system is built for verification.
