如果在用戶程序中使用PPI主站模式。S7-200CPU在運行模式下可以做主站。在使用PPI主站模式之后，可以使網絡讀寫指令來讀寫另外的一個S7-200。當S7-2000作PPI主站時，他仍然可以做從站來響應其他主站的請求。可以使用所有的PPI協議和所有的S7-200CPU通訊，當與EM277通訊時，必須使用PPI高級。MPI協議MPI允許主-主通訊和主-從通訊，與一個S7-200CPU通訊，STEP 7-Micro/WIN建立主-從連接。MPI協議不能和一個作為主站的S7-200CPU通訊。網絡設備通過任意的兩個設備之間的連接通訊（由MPI協議管理），設備之間的通訊連接受S7-200或者EM277西門子S7-1500PLC開機小面板黑屏不顯示維修模(mo)塊(kuai)所支持的連接個數(shu)限(xian)制。對(dui)于(yu)MPI協議，S7-300和(he)S7-4000PLC可以用XGET和(he)XPUT指令(ling)來讀寫(xie)S7-200的數(shu)據（
