2 關(guan)閉所有(you)的(de)軟(ruan)件，尤其是占用通訊口的(de)軟(ruan)件，只(zhi)保留西門子S7-200plc編程軟件。
3 要與西(xi)門(men)子推出(chu)的西(xi)門(men)子S7-200 CN CPU 正常通(tong)信，必須滿足(zu)以下條件(jian)：
使用編程軟件 STEP 7-Micro/WIN V4.0 SP3 以(yi)上版(ban)
將(jiang)編程(cheng)軟件的工(gong)作環境(jing)設置為中(zhong)文狀(zhuang)態。

如果不滿足上述條件(jian)，會在下載通信時遇(yu)到 82 號錯(cuo)誤(wu)。如果已經滿足上述條件(jian)而仍然遇(yu)到錯(cuo)誤(wu)，請檢查是否其(qi)他原因(yin)。
4 使用原裝USB/PPI電纜(lan)，需(xu)要將編程(cheng)軟件(jian)升級到(dao)當前發布的版本，并且(qie)在(zai)設(she)置(zhi)PG/PC接口的時候要選擇(ze)USB，非原裝USB電纜(lan)需(xu)要正確(que)選擇(ze)COM口（電腦-屬性-硬件-設(she)備管理器-端口）
5 在“Set PG/PC”通信屬(shu)性時，COM口的符號前為什么會有一個星號“*”？COM口前面的星號說(shuo)明(ming)它被其(qi)他軟件占用，Micro/WIN不能(neng)使用。
6 非(fei)原(yuan)裝USB電(dian)纜(lan)實際上(shang)是COM電(dian)纜(lan)，是USB-COM電(dian)纜(lan)加(jia)上(shang)COM電(dian)纜(lan)，所以設置(zhi)(zhi)應該根據(ju)COM口(kou)來設置(zhi)(zhi)。
7 安裝(zhuang)了USB-COM驅動(dong)(dong)后，一(yi)定要將電纜重(zhong)新(xin)啟動(dong)(dong)。
