Profichip的VPC3+與智能從應用處理器接口的通信芯片。VPC3+處理完整的PROFIBUS-DP/ DPV1從協議獨立，減輕所有的時間關鍵任務通信的應用處理器。當VPC3+進行一個DP通信，它會自動設置所有DP-結構調整方案。所有必要的計時器和監測功能集成在芯片上。因此幾乎可用於應用程序的外部控制器的整個性能。-Profichip’s VPC3+ is a communication chip with processor interface for intelligent slave applications. VPC3+ handles the complete PROFIBUSDP/ DPV1 slave protocol independently and relieves the application processor of all time critical communication tasks. When VPC3+ carries out a DP communication it automatically sets up all DP-SAPs. All necessary timers and monitoring functions are integrated in the chip. Therefore almost the entire performance of the external controller is available for the application.
