S7-300C 集成高速計(jì)數(shù)器功能, 以314C 為例, 集成4 路60kHz的高速計(jì)數(shù)器。計(jì)數(shù)可分為：
1、連續(xù)計(jì)數(shù)--計(jì)到上跳到下限從新開始。
2、計(jì)數(shù)--計(jì)到上跳到下限等待新的觸發(fā)。
3、周期計(jì)數(shù)--從裝載值開始計(jì)數(shù), 到可設(shè)置上跳到裝載值從新計(jì)數(shù)。
操作
4.2 控制參數(shù)的設(shè)置
1、主計(jì)數(shù)方向可分上/下計(jì)數(shù)
2、門功能--只有在門打開時計(jì)數(shù)值才有效
1) 取消計(jì)數(shù)--門再次打開時計(jì)數(shù)值清零
2) 停止計(jì)數(shù)--門再次打開時計(jì)數(shù)從上次計(jì)數(shù)值開始計(jì)數(shù)
3、開始/停止值--周期計(jì)數(shù)時上限值
4、比較值--用于產(chǎn)生中斷
5、滯后值— 可防止臨界時產(chǎn)生的擾動
操作參數(shù)
4.3 輸入/輸出的設(shè)置
1、輸入--1) 脈沖, 2) 硬件門, 3) 計(jì)數(shù)方向, 硬件門可使計(jì)數(shù)值更加
2、輸出--1) 設(shè)置比較器用于觸發(fā)快速輸出 2) 可設(shè)置輸出點(diǎn)脈沖時間
輸入輸出設(shè)置
4.4 中斷設(shè)置
產(chǎn)生中斷調(diào)用OB40(在basic parameters 選擇中斷或診斷+中斷)。
基本參數(shù)選擇中斷
中斷可選擇：
1、硬件門開中斷 2、硬件門關(guān)中斷 3、接近比較值中斷4、超上限中斷 5、超下限中斷
