通過密(mi)碼(ma)進行知識(shi)保護，防(fang)止未經(jing)授權讀取和修改(gai)程序塊

通過復(fu)制(zhi)保(bao)護來提高保(bao)護程度，防止未經授(shou)權(quan)而復(fu)制(zhi)程序塊(kuai)：

通過復制保(bao)護(hu)，可(ke)將(jiang) SIMATIC 存儲卡上的(de)程序(xu)(xu)塊與其序(xu)(xu)列號(hao)綁定，以便只有在將(jiang)配置(zhi)的(de)存儲卡插到 CPU 中時，該程序(xu)(xu)塊才(cai)可(ke)運(yun)行。

具(ju)有四(si)個不(bu)同授權(quan)級別的(de)權(quan)限：

西門子S7-1500PLC撥碼開關斷掉修理檢測中心可向各個用戶組(zu)分配不(bu)同訪(fang)問(wen)權限(xian)。通(tong)過新的保護級別(bie) 4，還可以限(xian)制與 HMI 設(she)備之間(jian)的通(tong)信。

改進了操作保護：

控制器(qi)將會(hui)檢測到組(zu)態(tai)數(shu)據的更改或未(wei)授(shou)權(quan)傳輸。
