概述

• CPU 具有中等規(guī)模的程序存儲器和程序框架
• 對二進(jìn)制和浮點(diǎn)數(shù)運(yùn)算具有較高的處理能力
• 在具有集中式和分布式I/O的生產(chǎn)線上作為集中式控制器使用
• 在PROFINET上實(shí)現(xiàn)基于組件的自動化
• PROFINET 代理，用于基于部件的自動化（CBA）中的 PROFIBUS DP 智能設(shè)備
• PROFINET I/O 控制器，用于在PROFINET上運(yùn)行分布式I/O
• 用于 2 端口交換機(jī)的 PROFINET 接口
• 組合 MPI/PROFIBUS DP-主/從接口
• 在PROFIBUS上實(shí)現(xiàn)等時模式

CPU 運(yùn)行需要 SIMATIC 微存儲卡(MMC)

應(yīng)用

CPU 315-2 PN/DP 具有中等規(guī)模程序量.除了分布式I/O結(jié)構(gòu)，它還可用于分布式自動化結(jié)構(gòu)?？稍赟IMATIC S7-300中用作PROFINET IO控制器以及標(biāo)準(zhǔn)PROFIBUS DP主站。CPU 315-2 PN/DP還可用作分布式智能從站(DP從站)。

CPU 315-2 PN/DP為采用軟件來實(shí)現(xiàn)一些簡單的工藝任務(wù)提供了一個理想的平臺，例如：

• Easy Motion Control 運(yùn)動控制
• 使用 STEP 7 塊或運(yùn)行軟件“標(biāo)準(zhǔn)/模塊化PID控制” 來實(shí)現(xiàn)閉環(huán)控制任務(wù)的解決方案

使用 SIMATIC S7-PDIAG 進(jìn)行擴(kuò)展過程診斷。

無需其他組件，通過CPU的集成組合就可以實(shí)現(xiàn)網(wǎng)絡(luò)自動化解決方案。

設(shè)計

CPU 315-2 PN/DP 裝配有：

• 微處理器;
  處理器處理每條二進(jìn)制指令執(zhí)行時間約為 50 ns，每條浮點(diǎn)數(shù)運(yùn)行指令約為 450ns。
• 384 KB 主存儲器（相當(dāng)于大約 128 K 條指令）；
  與程序組件執(zhí)行相關(guān)的大容量工作存儲器為用戶程序提供了充分的空間。作為程序裝載存儲器的微型存儲卡（zui大為 8 MB）也允許將可以項目（包括符號和注釋）保存在 CPU 中。裝載存儲器還可用于數(shù)據(jù)歸檔和配方管理。
• 靈活的擴(kuò)展；
  多達(dá) 32 個模塊，（４ 層結(jié)構(gòu)）
• MPI/DP 組合接口；
  *個集成的 MPI/DP 接口zui多能同時建立 16 個與 S7-300/400的連接或與編程器、PC 和 OP 的連接。 在這些連接中，始終分別為 PG 和 OP 各保留一個連接。
  MPI 可以通過“全局?jǐn)?shù)據(jù)通訊”與zui多32個CPU組建簡單的網(wǎng)絡(luò)。
  該接口可從MPI接口重新設(shè)置為DP接口。
  PROFIBUS DP 接口:
  DP 接口可用作 DP 主站或 DP 從站運(yùn)行。在該接口上，PROFIBUS DP從站可在等時模式下運(yùn)行．全面支持 PROFIBUS DP V1 標(biāo)準(zhǔn)。這將增加 DP V1 標(biāo)準(zhǔn)從站在診斷和參數(shù)賦值能力的范圍。
• 以太網(wǎng)接口；
  CPU 315-2 PN/DP 的第 2 個內(nèi)置接口是一個基于以太網(wǎng) TCP/IP 的 PROFINET 接口，帶有雙端口交換機(jī)。
  它支持下列協(xié)議：
  • S7通訊用于在SIMATIC控制器間進(jìn)行數(shù)據(jù)通訊;
  • 通過 STEP 7 進(jìn)行編程、啟動和診斷的 PG/OP 通訊;
  • 與HMI和SCADA連接的PG/OP通訊;
  • 在PROFINET上實(shí)現(xiàn)開放的TCP/IP、UDP和ISO-on-TCP (RFC1006)通訊；
  • SIMATIC NET OPC-Server用于與其它控制器以及CPU自帶的I/O設(shè)備進(jìn)行通訊

• 口令保護(hù);
  用戶程序使用密碼保護(hù)，可防止非法訪問。
• 診斷緩沖;
  zui后500個故障和中斷事件保存在該緩沖區(qū)中，供診斷使用。
• 免維護(hù)的數(shù)據(jù)后備;
  在電源恢復(fù)后，CPU 自動保存所有數(shù)據(jù)（zui大128KB），當(dāng)重新上電后，可繼續(xù)保留這些數(shù)據(jù)。

可參數(shù)化的特性

可以使用 STEP 7 對 S7 的組態(tài)、屬性以及CPU的響應(yīng)進(jìn)行參數(shù)設(shè)置：

• MPI多點(diǎn)接口;
  定義站地址
• 啟動；
  定義 CPU 的啟動特性
• 同步循環(huán)中斷；
  設(shè)置 DP 主站系統(tǒng)、過程映像分區(qū)編號和延時時間
• 循環(huán)/時鐘存儲器；
  zui大循環(huán)時間和負(fù)載。設(shè)置時鐘存儲器地址

  定義診斷報警的處理和范圍
• 時鐘；
  設(shè)定AS內(nèi)或MPI上的同步類型
• 防護(hù)等級；
  定義程序和數(shù)據(jù)的訪問權(quán)限
• 通訊；
  保留連接源
• Web；
  CPU 的 Web 服務(wù)器設(shè)置
• PROFIBUS DP 主站/從站接口;
  為分布式 I/O 分配用戶地址。
• PROFINET 接口；
  使用 NTP 處理時間同步參數(shù)

顯示功能與信息功能

• 狀態(tài)和故障指示；
  發(fā)光二極管顯示，例如，硬件、編程、定時器、I/O、總線故障以及運(yùn)行狀態(tài)，如RUN、STOP、Startup。
• 測試功能；
  可使用編程器顯示程序執(zhí)行過程中的信號狀態(tài)，可以不通過用戶程序而修改過程變量，以及輸出堆棧內(nèi)容。
• 信息功能；
  通過編程器以文本形式為用戶提供存儲能力信息、CPU的運(yùn)行模式，以及工作存儲器和裝載存儲器當(dāng)前的使用情況、當(dāng)前的循環(huán)時間和診斷緩沖區(qū)的內(nèi)容。
