基于FPGA的Profibus-DP智能从站设计

Design of Profibus-DP Slave Based on FPGA

提出了FPGA结合专用ASIC芯片SPC3的Profibus-DP智能从站的设计方案,并详细介绍了FPGA配合SPC3在80C32模式下工作的时序设计,利用S7-300搭建Profibus总线网络测试,结果验证了设计的正确性。该设计为Profibus-DP智能从站的简单设计提供了一种新的思路和方法。

A new design of Profibus-DP intelligent slave which having FPGA combined with dedicated ASIC chip SPC3 was proposed,including the introduction of timing sequence design of the FPGA which working with SPC3 in 80C32 mode in detail.Testing S7-300-assisted Profibus platform well proves this design which providing a new perspective and way for the Profibus-DP intelligent slave design.
