Besides, the most important function of the network monitoring system develop by this research is different with other ones, which have been used: he/she can use other PC, which have authorized by Server PC, to modify the Server PC applications, there are many functions include: test software and hardware remotely, debug remotely and execute application remotely, etc.. Anyway, when problems happen in Server PC, in most case we can fix problems by other PC. Users can arbitrary add/subtract functions and applications in order to improve efficiency of system, without modifying Distributed Data Acquest Module.

本研究所发展的监控系统，除了可在网页上浏览动态资料外，其与现有既存的网路监控系统最大的差异在於：可在任何一台经过授权的电脑修改伺服电脑的程式，其中包括：远端测试软硬体、远端故障排除、遥控启动程式；也就是说，当大部分情况发生时，人员不需要到达现场，即可将问题排除，且在不变更资料撷取模组等相关硬体的前提下，可在远端依现场的需要，任意的增加或删除伺服电脑的功能和程式，进而达到最佳的工作效率。
