系統(tǒng)安全
PAC系統(tǒng)支持以下兩種系統(tǒng)安全類型:
密碼/授權(quán)級(jí)別
■OEM保護(hù)
密碼和授權(quán)級(jí)別
密碼是PAC系統(tǒng)CPU的一個(gè)可配置的特性。可以選擇是否使用密碼。在編程軟件中進(jìn)行密碼設(shè)置。編程器在線時(shí)，密碼為編程器的訪問(wèn)設(shè)定了級(jí)別。下線模式下， 密碼失效。
缺省狀態(tài)是沒(méi)有密碼保護(hù)。CPU的每個(gè)權(quán)力等級(jí)可以有一個(gè)密碼。密碼長(zhǎng)度為1~7ASCII個(gè)字符。只能使用編程軟件更改密碼。
設(shè)定密碼之后，通過(guò)任何通訊形式訪問(wèn)CPU都要正確的輸入相應(yīng)權(quán)力級(jí)別的密碼。密碼通過(guò)校驗(yàn)后，訪問(wèn)可以進(jìn)行本個(gè)級(jí)別和更低級(jí)別的訪問(wèn)(例如，正確輸入了第3級(jí)密碼以后，可以訪問(wèn)1, 2，3級(jí)的功能)
注意:CPU的運(yùn)行模式轉(zhuǎn)換會(huì)覆蓋密碼。即使在編程器上不能進(jìn)行運(yùn)行/停止模式的轉(zhuǎn)換，也可以通過(guò)CPU上的轉(zhuǎn)換開(kāi)關(guān)進(jìn)行轉(zhuǎn)換。
