2.產(chǎn) 品 詳 情 資 料：
B&R ECEP128-0每當(dāng)Bug使用NVRAM中的參數(shù)時，首先通過校驗和測試NVRAM內(nèi)容，以確保NVRAM內(nèi)容的完整性。在BBRAM校驗和失敗的情況下，假設(shè)某些默認值如下所述。錯誤操作參數(shù)（保存在NVRAM中）在通電/熱復(fù)位時不會自動初始化。由Bug用戶調(diào)用ENV命令。一旦ENV命令被無錯誤地調(diào)用和執(zhí)行，Bug默認值和/或用戶參數(shù)將與校驗和數(shù)據(jù)一起加載到NVRAM中。B&R ECEP128-0如果任何操作參數(shù)已被修改，則在重置/通電條件出現(xiàn)之前，新參數(shù)不會生效。如果確定NVRAM內(nèi)容已損壞，請使用雙按鈕重置（在第3章重新啟動系統(tǒng)中介紹）重新初始化系統(tǒng)。如果在命令行上沒有選項的情況下調(diào)用ENV命令，系統(tǒng)將提示您配置所有操作參數(shù)。如果使用選項D調(diào)用ENV命令，ROM默認值將加載到NVRAM中。B&R ECEP128-0
Any time the Bug uses a parameter from NVRAM, the NVRAM contents are first tested by checksum to insure the integrity of the NVRAM contents. In the instance of BBRAM checksum failure, certain default values are assumed as stated below. The bug operational parameters (which are kept in NVRAM) are not initialized automatically on power up/warm reset. It is up to the Bug user to invoke the ENV command. Once the B&R ECEP128-0ENV command is invoked and executed without error, Bug default and/or user parameters are loaded into NVRAM along with checksum data. If any of the operational parameters have been modified, the new parameters do not go into effect until a reset/powerup condition occurs. Should you determine that the NVRAM contents have been corrupted, use a double-button reset (described under Restarting the System in Chapter 3) to reinitialize the system. If the ENV command is invoked with no options on the command line, you are prompted to configure all operational parameters. If the ENV command is invoked with the option D, ROM defaults will be loaded into NVRAM.B&R ECEP128-0
