    S7-300 集成PN口作客戶端與S7-300/400/1200/1500的 S7 單邊通信(STEP7)

    S7 協(xié)議是 SIEMENS S7系列產(chǎn)品之間通訊使用的標(biāo)準(zhǔn)協(xié)議,其優(yōu)點(diǎn)是通信雙方無論是在同一 MPI 總線上、同一 PROFIBUS 總線上或同一工業(yè)以太網(wǎng)中,都可通過 S7 協(xié)議建立通信連接,使用相同的編程方式進(jìn)行數(shù)據(jù)交換而與使用何種總線或網(wǎng)絡(luò)無關(guān)。S7 通信按組態(tài)方式可分為單邊通信和雙邊通信,單邊通信通常應(yīng)用于以下情況:

    • 通信伙伴無法組態(tài) S7 連接
    • 通信伙伴不允許停機(jī)
    • 不希望在通訊伙伴側(cè)增加通信組態(tài)和程序

    本文檔簡要介紹在STEP7 V5.5環(huán)境下,S7-300 集成PN口的CPU基于工業(yè)以太網(wǎng)的S7單邊通信的組態(tài)步驟,用于實(shí)現(xiàn)與S7-300/400/1200/1500 CPU之間的S7 通信。

    1、硬件與軟件條件

    CPU 1212C 1 6ES7212-1AE40-0XB0 V4.2

    表 2軟件環(huán)境

    2、組態(tài)配置

    2.1 通過如下的步驟配置編程電腦的IP地址:

    選擇電腦的“ 控制面板 > 網(wǎng)絡(luò)和共享 > 本地連接>屬性”打開 Internet Protocol Version 4(TCP/IPv4),設(shè)置PC的 IP 地址,本例中為192.168.0.131。

    圖1.設(shè)置PC地址

     

    2.2 在STEP7 中組態(tài)315-2PN/DP CPU,雙擊X2卡槽,再點(diǎn)擊屬性按鈕以設(shè)置IP地址。(具體步驟請參見文檔:CPU硬件組態(tài)入門)

    圖2.S7-300硬件組態(tài)

    圖3.PN-IO屬性

     

    2.3 設(shè)置好IP地址后(本例中為192.168.0.1),點(diǎn)擊New按鈕添加一條子網(wǎng)Ethernet(1),如果已經(jīng)存在子網(wǎng),也可選中該子網(wǎng)直接點(diǎn)OK按鈕即可。

    圖4.添加IP地址和子網(wǎng)

     

    2.4 點(diǎn)擊快捷菜單中的Configure Network按鈕進(jìn)入Netpro視圖。

    圖5.點(diǎn)擊Configure Network按鈕

     

    2.5 在Netpro視圖的CPU上點(diǎn)右鍵選擇Insert New Connection添加新連接。

    圖6.添加新連接

     

    2.6 通訊伙伴選擇非指定(Unspecified),通訊類型選擇S7 connection。

    圖7.選擇通信伙伴和通信類型

     

    2.7 點(diǎn)擊OK后在彈出的屬性窗口中勾選單端組態(tài)(Establish an active connection),并填寫通信伙伴的IP地址,注意Local ID編號,本例保持默認(rèn)值1。點(diǎn)擊詳細(xì)按鈕。

    圖8.S7連接屬性

     

    2.8 在地址詳細(xì)信息對話框中填寫通信伙伴CPU的機(jī)架號和槽號,如通信伙伴是S7-300/400 CPU則槽號為2,如通信伙伴是S7-1200/1500 CPU則槽號為1。點(diǎn)擊OK。

    圖9.S7地址詳細(xì)

    2.9 選中CPU,先編譯再下載

    2.10 下載完成后,可點(diǎn)擊“激活連接狀態(tài)”按鈕,查看連接狀態(tài),如下圖所示,則表示組態(tài)的連接已經(jīng)成功建立。

    圖11.連接已建立

    2.11 如果出現(xiàn)如下圖所示的情況,則說明連接沒有建立,請檢查網(wǎng)線的連接、IP地址等。

    圖12.連接未建立

    3、編寫PLC程序,調(diào)用通訊塊

    3.1 組態(tài)連接建立成功后,需要調(diào)用通訊功能塊PUT和GET進(jìn)行數(shù)據(jù)交換。S7-300用于通訊連接的功能塊位于標(biāo)準(zhǔn)庫中,如下圖所示:

    圖13.PUT GET指令位置

     

    3.2調(diào)用PUT指令,本例中本地S7-300 CPU將DB10.DBB0開始的10個字節(jié)寫入通信伙伴CPU 的DB11.DBB0開始的10個字節(jié)中。

    圖14.PUT指令

    參數(shù) 說明
    REQ 上升沿觸發(fā),一次上升沿發(fā)送一次數(shù)據(jù)
    ID 連接ID(參看圖8)
    ADDR_1 指向伙伴CPU接收地址區(qū)域
    SD_1 指向本地CPU發(fā)送地址區(qū)域
    DONE 發(fā)送完成(上升沿)
    ERROR 有故障發(fā)生(上升沿)
    STATUS 故障代碼

    表 3 PUT管腳說明

    3.3調(diào)用GET指令,本例中將通信伙伴CPU的DB20.DBB0開始的10個字節(jié)讀入到本地S7-300 CPU的DB21.DBB0開始的10個字節(jié)中。

    圖15.GET指令

    參數(shù) 說明
    REQ 上升沿觸發(fā),一次上升沿讀取一次數(shù)據(jù)
    ID 連接ID(參看圖8
    ADDR_1 指向伙伴CPU發(fā)送地址區(qū)域
    RD_1 指向本地CPU接收地址區(qū)域
    DONE 接收完成(上升沿)
    ERROR 有故障發(fā)生(上升沿)
    STATUS 故障代碼

    表 4 GET管腳說明

    3.4 S7-300 CPU做S7通訊的客戶端時,伙伴CPU無需組態(tài)編程,準(zhǔn)備好相應(yīng)的數(shù)據(jù)區(qū)即可,如本例中的DB10和DB20。如果伙伴方是S7-1200(固件版本V4.0以上)或是S7-1500 CPU,需要在CPU屬性的連接機(jī)制中勾選"允許來自遠(yuǎn)程對象的PUT/GET通信訪問",如下圖所示:
