【正文】 throughThere are four interface for single and redundant transmission:2 a bination of RS232 / RS485 interface used to connect the classical WAN, such as special line, wireless or dialup networkRJ45 interface used to connect to based on IP network (WAN or LAN), such as FOC, DSL, GPRS, etcCompact ponents used for a variety of USES:As an independent unit (independent operation without S7300 CPU), TIM can bear SINAUT munication used in one or more S7400 PLC or control center PC (SINAUT ST7cc or ST7sc)。 The connection is through the TIM one of Ethernet port4 di / 10 doThis machine simulation the input/output pointCPU 224 xp has two AI / 1 ao. hardware wiring diagram munication modeThe internal integrated PPI interface for users provide a powerful munication function. PPI interface for RS485, can be in three ways:1. The PPI ways: PPI munication protocol is designed for Siemens S7200 series PLC development of munication protocol. Through the general pass two core shielded twistedpair cable for networking. Baud rate is kbit/s, kbit/s and kbit/s. The CPU integrated programming mouth at the same time is PPI munication network interface.2. MPI ways: through the builtin interface connected to the MPI network. Baud rate is kbit/s, kbit/s. S7200 with S7300/400 munication, S7200 CPU in MPI network as slave station, each other can39。t munication.3. Free munication port means: is a very distinctive function. S7200 PLC can with any munication protocol open other equipment munication. That can be defined by the user to munication protocols. Baud rate highest kbit/s.4. Profibusdp network: CPU222, 224 xp, 226 can be EM277 by increasing the method supports PROFIBUS DP network protocol. The highest transmission rate for 12 mbit/s. EEPROM memory module (option)Can be used as a modification with copy program rapid tool (without programmer), and may carry on auxiliary software filing work. the battery moduleFor long time data backup. User data (such as mark a state, data block, timer, counter) through the internal super capacitance storage about 5 days. Choose the battery module can extend the storage time to 200 days (10 years of my life). The battery module inserted in the memory module card slot.總結(jié)：通過閱讀全自動(dòng)洗衣機(jī)設(shè)計(jì)全部過程，發(fā)現(xiàn)自己的專業(yè)英語(yǔ)還是存在著一定的不足，首先是不能夠靈活應(yīng)用每個(gè)單詞的含義，導(dǎo)致在翻譯過程中，容易將單詞的意思曲解，這就給翻譯造成了很大的影響，為了能夠及時(shí)的糾正錯(cuò)誤，我利用了網(wǎng)絡(luò)上的“有道詞典”進(jìn)行一一的校對(duì)，在這里還要感謝張磊老師給予的幫助，使我順利的完成了此次的項(xiàng)目作業(yè)。七、參考資料：[1] :機(jī)械工業(yè)出版社 [2] 陳懇. 專業(yè)英語(yǔ)（電類用）. 北京:機(jī)械工業(yè)出版社 [3] 有道翻譯工具；
