CX1100-0002該網(wǎng)絡(luò)的主要特點(diǎn)：

（1）網(wǎng)絡(luò)可容納的通訊節(jié)點(diǎn)數(shù)量可靈活組態(tài)

（2）網(wǎng)絡(luò)的通信速率為500Kbps

（3）網(wǎng)絡(luò)通訊協(xié)議：PROFIBUS-DP

（4）每臺(tái)聯(lián)網(wǎng)的PLC或傳動(dòng)裝置均裝有一塊網(wǎng)絡(luò)接口模塊

（5）PLC與傳動(dòng)間的各種控制信號(hào)和狀態(tài)信息都可以通過網(wǎng)絡(luò)實(shí)現(xiàn)（包括數(shù)字信號(hào)和模擬信號(hào)）
