摘要
针对101(104)规约在调试运行中的一些常见问题,着重以分析报文为手段,介绍了数字通道、模拟通道的优缺点、101(104)规约设置时的注意点,分析了如何选择适合的101规约通道方式、101规约时对时是否达标的判别。对改造扩建中误遥控问题、通道误码率较大的问题、遥测死区值的问题,变压器档位上送问题、通信服务器的可利用资源问题进行了分析,并提出解决方法。介绍了判别104规约对时是否达标的方法,指出了分析报文对于发现规约通信问题的重要性。
The pro and con of digital channel and analog channel,the setup points of IEC 60870-5-101/104 transmission protocols(101/104 protocols)are introduced for the debug common problems of 101/104 protocols by analyzing messages.How to choose proper channel mode of protocol 101 and differentiate eligible timing alignment of protocols 101 is analyzed.The issues of error telecontrol of rebuild,high error code rate of channel,telemeter dead zone value,submittion of transformer layers and available resource of communication server are analyzed and resolved.The method of differentiating timing alignment of protocol 104 is presented,and the importance of discovering protocol communication problems by analyzing messages is pointed out.
