6SN1111-0AA00-0CA1PLC在正式運(yùn)行時(shí)，不需要編程器。編程器主要用來(lái)進(jìn)行用戶程序的編制、存儲(chǔ)和管理等，并將用戶程序送入PLC中，在調(diào)試過(guò)程中，進(jìn)行監(jiān)控和故障檢測(cè)。S7-200系列PLC可采用多種編程器，一般可分為簡(jiǎn)易型和智能型。
簡(jiǎn)易型編程器是袖珍型的，簡(jiǎn)單實(shí)用，價(jià)格低廉，是一種很好的現(xiàn)場(chǎng)編程及監(jiān)測(cè)工具，但顯示功能較差，只能用指令表方式輸入，使用不夠方便。智能型編程器采用計(jì)算機(jī)進(jìn)行編程操作，將專用的編程軟件裝入計(jì)算機(jī)內(nèi)，可直接采用梯形圖語(yǔ)言編程，實(shí)現(xiàn)在線監(jiān)測(cè)，非常直觀，且功能強(qiáng)大，S7-200系列PLC的專用編程軟件為STEP7-Micro/WIN。
4．程序存儲(chǔ)卡
為了保證程序及重要參數(shù)的安全，一般小型PLC設(shè)有外接EEPROM卡盒接口，通過(guò)該接口可以將卡盒的內(nèi)容寫入PLC，也可將PLC內(nèi)的程序及重要參數(shù)傳到外接EEPROM卡盒內(nèi)作為備份。程序存儲(chǔ)卡EEPROM有6ES 7291-8GC00-0XA0和6ES 7291-8GD00-0XA0兩種，程序容量分別為8K和16K程序步。
5．寫入器
寫入器的功能是實(shí)現(xiàn)PLC和EPROM之間的程序傳送，是將PLC中RAM區(qū)的程序通過(guò)寫入器固化到程序存儲(chǔ)卡中，或?qū)LC中程序存儲(chǔ)卡中的程序通過(guò)寫入器傳送到RAM區(qū)。
6．文本顯示器6SN1111-0AA00-0CA1
文本顯示器TD200不僅是一個(gè)用于顯示系統(tǒng)信息的顯示設(shè)備，還可以作為控制單元對(duì)某個(gè)量的數(shù)值進(jìn)行修改，或直接設(shè)置輸入/輸出量。文本信息的顯示用選擇/確認(rèn)的方法，*多可顯示80條信息，每條信息*多4個(gè)變量的狀態(tài)。過(guò)程參數(shù)可在顯示器上顯示，并可以隨時(shí)修改。TD200面板上的8個(gè)可編程序的功能鍵，每個(gè)都分配了一個(gè)存儲(chǔ)器位，這些功能鍵在啟動(dòng)和測(cè)試系統(tǒng)時(shí)，可以進(jìn)行參數(shù)設(shè)置和診斷。
