口令保護：多級口令保護可以使用戶高度、有效地保護其技術(shù)機密，防止未經(jīng)允許的復制和修改，操作方式選擇開關(guān)：操作方式選擇開關(guān)像鑰匙一樣可以拔出，當鑰匙拔出時，就不能改變操作方式。這樣就防止非法刪除或改寫用戶程序。
通訊
這是一個經(jīng)濟而有效的解決方案；方便用戶的STEP7的用戶界面提供了通訊組態(tài)功能，這使得組態(tài)非常容易、簡單。
  SIMATICS7—300具有多種不同的通訊接口：多種通訊處理器用來連接AS—I接口和工業(yè)以太網(wǎng)總線系統(tǒng)；串行通訊處理器用來連接點到點的通訊系統(tǒng)；多點接口(MPl)集成在CPU中，用于同時連接編程器、PC機、人機界面系統(tǒng)及其他SIMATICS7/M7／C7等自動化控制系統(tǒng)。CPU支持下列通訊類型：
  過程通訊：通過總線(AS—I或Pronbus)對I/O模塊周期尋址(過程映象交換)。
  數(shù)據(jù)通訊：在自動控制系統(tǒng)之間、人機界面(HMl)和幾個自動化功能塊間相互調(diào)用。
