綜合以上闡述可得出采用統(tǒng)一介質(zhì)訪問層、標(biāo)準(zhǔn)tcp/ip傳輸網(wǎng)絡(luò)層和開放應(yīng)用層的以太網(wǎng)來實(shí)現(xiàn)這些第三方通訊設(shè)備聯(lián)網(wǎng)，是此流程自動(dòng)化控制的*方案，因此針對(duì)上述工業(yè)數(shù)據(jù)采集領(lǐng)域的現(xiàn)狀，我們制定了基于tcp/ip的以太網(wǎng)通信解決方案，包括設(shè)備投資、布線、維護(hù)和編程難易程度所產(chǎn)生的總體成本可大為降低，它不單獨(dú)占用處理器物理端口和處理資源，在靈活性和可用性方面可有*的提升，與plc控制層的協(xié)同工作效率也得到了提高，降低了維護(hù)成本并進(jìn)一步簡(jiǎn)化了網(wǎng)絡(luò)結(jié)構(gòu)，并對(duì)今后系統(tǒng)功能擴(kuò)充及升級(jí)也帶來了*的便利，符合各制造商們?nèi)找骊P(guān)注的價(jià)值主張。

3 開放式ie功能實(shí)現(xiàn)

3.1系統(tǒng)組成

本系統(tǒng)現(xiàn)場(chǎng)設(shè)備主要包含有：godex熱敏標(biāo)簽條碼打印機(jī)、metrologic條形碼掃描儀、tcs電子臺(tái)秤和輥道秤等等，為滿足這些設(shè)備數(shù)據(jù)處理和控制的要求，采用帶有cp343-1通信處理機(jī)的s7-300plc并充分利用工廠現(xiàn)有的局域網(wǎng)資源，組成一個(gè)基于tcp/ip數(shù)據(jù)流的工業(yè)以太網(wǎng)通信方案，以滿足各工藝段的需要，也使s7-300plc資源得到充分的利用和發(fā)揮，

s7-300cp模板的s7應(yīng)用程序是基于s5兼容接口send/receive來實(shí)現(xiàn)開放式ie通信，cp它zui多可同時(shí)建立16個(gè)tcp/ip任務(wù)資源的連接，雖然tcp/ip是基于面向數(shù)據(jù)流通信的服務(wù)，而非基于消息的數(shù)據(jù)包傳輸服務(wù)，這就意味著發(fā)送的數(shù)據(jù)沒有任何有用于數(shù)據(jù)的信息，例如長(zhǎng)度、起始和結(jié)束信息，接收端只能提供相對(duì)應(yīng)的接收長(zhǎng)度和特征符來獲取正確的信息，因此需考慮send/receive收發(fā)功能的輸出參數(shù)及狀態(tài)的判別，來協(xié)調(diào)雙方的請(qǐng)求和響應(yīng)以確保雙方可靠通信，另外對(duì)于接收方還需注意接收緩沖區(qū)數(shù)據(jù)流的定位問題，總之send/receive接口所集成的基于tcp/ip的socket接口訪問為實(shí)現(xiàn)與第三方設(shè)備的數(shù)據(jù)交換提供了靈活多樣服務(wù)。
