Kuthamanga kwa Modbus TCP Reference Design pa SmartFusion2 Zida Zogwiritsa Ntchito IwIP ndi FreeRTOS
Mawu Oyamba
Microsemi imapereka mawonekedwe opangira zida za SmartFusion®2 SoC FPGA zomwe zimawonetsa
Tri-speed ethernet medium access controller (TSEMAC) mawonekedwe a SmartFusion2 SoC FPGA ndipo amagwiritsa ntchito protocol ya Modbus. Kapangidwe kazowunikira kumayendera UG0557: SmartFusion2 SoC FPGA Advanced Development Kit User Guide. Buku lachiwonetseroli likufotokoza.
- Kugwiritsa ntchito SmartFusion2 TSEMAC yolumikizidwa ndi serial gigabit media independent interface (SGMII) PHY.
- Kuphatikizika kwa dalaivala wa SmartFusion2 MAC wokhala ndi njira yopepuka ya IP (IwIP) transmission control protocol (TCP) kapena stack ya IP ndi pulogalamu yaulere ya nthawi yeniyeni (RTOS).
- Wosanjikiza wogwiritsa ntchito ndi protocol automation protocol, Modbus pa TCP kapena IP.
- Momwe mungayendetsere zolembera
Microcontroller subsystem (MSS) ya SmartFusion2 SoC FPGA ili ndi chitsanzo cha zotumphukira za TSEMAC. TSEMAC ikhoza kukhazikitsidwa pakati pa purosesa yolandirira ndi netiweki ya Ethernet pamitengo yotsatsira iyi (mawilo a mzere):
