        SIMATIC S7-300, CPU 314C-2PN/DP 緊湊型CPU帶有192 KB工作存儲區, 24 數字量輸入/16 數字量輸出, 4模擬量輸入, 2模擬量輸出, 1 PT100, 4 快速計數器 (60 KHZ), 1. 接口 MPI/DP 12MBIT/S, 2. 接口以太網 PROFINET, 含 2個 PORT SWITCH, 集成 24V DC 電源, FRONT C

        S7-300CPU314C-2PN/DP   概述

        CPU 運行需要 SIMATIC 微存儲卡(MMC)。

        S7-300CPU314C-2PN/DP  應用領域

        CPU 314C-2 DP 是緊湊型 CPU,適合安裝在分布式結構中。通過其擴展工作存儲器,該緊湊型CPU也適用于中等規模的應用。集成的數字量和模擬量輸入和輸出可與過程信號直接連接。集成的 的PROFIBUS DP 主站/從站以及 PROFINET IO 控制器/I-設備接口,用于 PROFIBUS 和 PROFINET 的分布式連接。這使得 CPU 314C-2 PN/DP 可作為進行快速處理的分布式單元使用,也可作為 PROFIBUS 和 PROFINET 系統中具有低端現場總線系統的上位控制器。
