第一章 概要
Z－CTIF 是為使用 SZ－3/4 CPU 特殊功能而提供的外部信號(hào)接口模塊，它只能安裝于緊靠 CPU
右側(cè)的 0 號(hào)槽中，通過(guò)特殊寄存器設(shè)定。Z－ CTIF 可作為加法計(jì)數(shù)器，定位控制器，脈沖捕捉器等
來(lái)使用。
1－1、功能
根據(jù)CPU型號(hào)的不同，其可實(shí)現(xiàn)的功能也不同。

·加法計(jì)數(shù)器 1點(diǎn) (5kcps、24段設(shè)定)
·外部中斷輸入 1點(diǎn) (0.1ms脈沖)
·脈沖捕捉輸入 1點(diǎn) (0.1ms脈沖)
·普通輸入 4點(diǎn) (帶軟件濾波)
2． 使用SZ－4時(shí)
·加減計(jì)數(shù)器 1點(diǎn) (90o相位差2相信號(hào)/加、減個(gè)別信號(hào)5kcps、24段設(shè)定)
·加法計(jì)數(shù)器 2點(diǎn) (5kcps、24段設(shè)定)
·外部中斷輸入 4點(diǎn) (0.1ms脈沖)
