冗余模塊 1769-IQ16
可編程邏輯控制器系統(tǒng)的通信接口應(yīng)包括串行和并行通信接口、RIO通信口、常用DCS接口等；大中型可編程邏輯控制器通信總線（含接口設(shè)備和電纜）應(yīng)1：1冗余配置，通信總線應(yīng)符合國(guó)際標(biāo)準(zhǔn)，通信距離應(yīng)滿足裝置實(shí)際要求。
可編程邏輯控制器系統(tǒng)的通信網(wǎng)絡(luò)中，上級(jí)的網(wǎng)絡(luò)通信速率應(yīng)大于1Mbps，通信負(fù)荷不大于60%。可編程邏輯控制器系統(tǒng)的通信網(wǎng)絡(luò)主要形式有下列幾種形式：
1）、PC為主站，多臺(tái)同型號(hào)可編程邏輯控制器為從站，組成簡(jiǎn)易可編程邏輯控制器網(wǎng)絡(luò)；
2）、1臺(tái)可編程邏輯控制器為主站，其他同型號(hào)可編程邏輯控制器為從站，構(gòu)成主從式可編程邏輯控制器網(wǎng)絡(luò)；
3）、可編程邏輯控制器網(wǎng)絡(luò)通過特定網(wǎng)絡(luò)接口連接到大型DCS中作為DCS的子網(wǎng)；
4）、專用可編程邏輯控制器網(wǎng)絡(luò)（各廠商的專用可編程邏輯控制器通信網(wǎng)絡(luò)）。
為減輕CPU通信任務(wù)，根據(jù)網(wǎng)絡(luò)組成的實(shí)際需要，應(yīng)選擇具有不同通信功能的（如點(diǎn)對(duì)點(diǎn)、現(xiàn)場(chǎng)總線、）通信處理器。
