CPU 運(yùn)行需要 SIMATIC 微存儲(chǔ)卡(MMC)
西門子CPU315-2PN/DP 應(yīng)用領(lǐng)域
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(dòng)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(jiǎn)單的工藝任務(wù)提供了一個(gè)理想的平臺(tái)，例如：
- Easy Motion Control 運(yùn)動(dòng)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(dòng)化解決方案。
西門子CPU315-2PN/DP 設(shè)計(jì)
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(shí)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(chǔ)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(chǔ)器為用戶程序提供了充分的空間。作為程序裝載存儲(chǔ)器的微型存儲(chǔ)卡（zui大為 8 MB）也允許將可以項(xiàng)目（包括符號(hào)和注釋）保存在 CPU 中。裝載存儲(chǔ)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(gè)模塊，（４ 層結(jié)構(gòu)） - MPI/DP 組合接口；
*個(gè)集成的 MPI/DP 接口zui多能同時(shí)建立 16 個(gè)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(gè)連接。
MPI 可以通過“全局?jǐn)?shù)據(jù)通訊"與zui多32個(gè)CPU組建簡(jiǎn)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(shí)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(gè)內(nèi)置接口是一個(gè)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(dòng)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
