SIMATIC S7-400 可采用具有不同性能級(jí)別的各種 CPU:
所有 CPU 裝在帶集成的控制單元和顯示單元的塑料外殼中。 相同的單元具有相同的功能。
前面板上有:
除 CPU 412-1 處理器外,所有 CPU 具有:
CPU 414-3 PN/DP, CPU 416-3 PN/DP 和 CPU 416F-3 PN/DP 也可以連接 PROFINET。 每個(gè)模板有一個(gè)雙口的 PROFINET 接口。
高端 CPU 還具有:
此外,CPU 按照其性能進(jìn)行分級(jí):例如RAM、地址區(qū)大小、可裝載塊的數(shù)量以及處理時(shí)間。
所有 S7-400 CPU 均具有兩種類(lèi)型的存儲(chǔ)器。工作存儲(chǔ)器的細(xì)分可將性能提高一倍。當(dāng)一個(gè)標(biāo)準(zhǔn)處理器需要訪(fǎng)問(wèn)其 RAM 至少兩次時(shí),S7-400 專(zhuān)用處理器可在一個(gè)循環(huán)周期中同時(shí)訪(fǎng)問(wèn)代碼存儲(chǔ)器和數(shù)據(jù)存儲(chǔ)器。因此,數(shù)據(jù)總線(xiàn)和代碼總線(xiàn)也是獨(dú)立的。工作存儲(chǔ)器的容量取決于從精細(xì)分級(jí)的 CPU 系列中所選取的適合的 CPU。
對(duì)于小型和中等程序,集成式負(fù)載內(nèi)存 (RAM) 就足夠了。對(duì)于較大的程序,可通過(guò)插入內(nèi)存卡來(lái)增加裝載內(nèi)存。插入式閃存卡可用于在不使用電池的情況下進(jìn)行永久性存儲(chǔ)。
相關(guān)功能 (FC) 和 功能塊 (FB) 可以加密的方式存儲(chǔ)于 CPU 以保護(hù)專(zhuān)門(mén)知識(shí)應(yīng)用。
