在传输数据的过程中,某个节点询问数据,但是其余节点缺少相关数据,询问指令就会重复发出,从而导致网络堵塞;
②网络通信介质损坏;3BSE018161R1
③ DCS 组态作业不规范,没有合理的实现I/O 连接,在读取数据的过程中,因负荷过载而导致网络堵塞;
④在软件升级后,驱动程序和硬件不匹配;
⑤历史数据内存占用过多,在数据传输高峰时期,就会出现频繁的网络堵塞,从而导致各个站点出现死机等问题;
⑥ DCS 硬件工作环境温度过高(常由散热系统故障导致)。
? 故障处理:
目前,并没有低成本且行之有效的方法来降低网络通信负荷,解决网络堵塞问题,通过日常检修以及维护来解决该问题仍旧有较大的难度,因此主要处理方法体现在提高日常维护水平上,日常维护方法为:
①频繁进行网络测试,提高网络测试频次,针对和所有系统的通信负荷率,确认机组的异常工作情况,在冗余切换的过程中,加强网络监控,调整数据传输时间,降低网络负载;
②在检修的过程中,复位DPU 以及数据站,删除无效的I/O,去除影响因素;3BSE018161R1处理器
③采用双层网结构构件DCS 系统,分离系统网络以及管理网络,提高网络运作稳定性;
④定期检测硬件工作环境,检查其散热系统是否在正常运作,检查各个接口是否正常;
⑤各个系统直接的数据传输采用单向传输协议;
⑥温度信号检测加入CRT,实现异常报警,避免温度异常影响系统运作;
