冗余模块 1769-IQ16
可编程逻辑控制器系统的通信接口应包括串行和并行通信接口、RIO通信口、常用DCS接口等;大中型可编程逻辑控制器通信总线(含接口设备和电缆)应1:1冗余配置,通信总线应符合国际标准,通信距离应满足装置实际要求。
可编程逻辑控制器系统的通信网络中,上级的网络通信速率应大于1Mbps,通信负荷不大于60%。可编程逻辑控制器系统的通信网络主要形式有下列几种形式:
1)、PC为主站,多台同型号可编程逻辑控制器为从站,组成简易可编程逻辑控制器网络;
2)、1台可编程逻辑控制器为主站,其他同型号可编程逻辑控制器为从站,构成主从式可编程逻辑控制器网络;
3)、可编程逻辑控制器网络通过特定网络接口连接到大型DCS中作为DCS的子网;
4)、专用可编程逻辑控制器网络(各厂商的专用可编程逻辑控制器通信网络)。
为减轻CPU通信任务,根据网络组成的实际需要,应选择具有不同通信功能的(如点对点、现场总线、)通信处理器。
