The Design of Communication Interface for Profibus-DP Slave Based on SPC3

Article Preview

Abstract:

A Profibus-DP transform interface was designed. TakingAT89S52 and SPC3 as core, hardware of interface, software flow and GSD file were designed. The interface implemented access of Profibus-DP for traditional instrument and field equipment which weren’t provided with Profibus communication ability. Test results show that the interface can run data communication with main station at high speed, with high reliability and versatility.
