With the popularity of the Profibus fieldbus applications,more and more smart field instruments proposed functional requirements for Profibus. STM32 combined with the communications chip VPC3 + C, completing a Modbus-Profibus total line bridge design, in which the VPC3+C realizes the Profibus-DP interface protocols, and the STM32 realizes the Modbus Communication protocol and the overall operation of the total line bridge. Testing shows that Modbus-Profibus bus bridge can realize Profibus communication function of the field devices and intelligent instruments, thus providing Profibus communication solutions with short development cycle, low cost and high efficiency.Read More
