@article{(Open Science Index):https://publications.waset.org/pdf/7619, title = {CNet Module Design of IMCS}, author = {Youkyung Park and SeungYup Kang and SungHo Kim and SimKyun Yook}, country = {}, institution = {}, abstract = {IMCS is Integrated Monitoring and Control System for thermal power plant. This system consists of mainly two parts; controllers and OIS (Operator Interface System). These two parts are connected by Ethernet-based communication. The controller side of communication is managed by CNet module and OIS side is managed by data server of OIS. CNet module sends the data of controller to data server and receives commend data from data server. To minimizes or balance the load of data server, this module buffers data created by controller at every cycle and send buffered data to data server on request of data server. For multiple data server, this module manages the connection line with each data server and response for each request from multiple data server. CNet module is included in each controller of redundant system. When controller fail-over happens on redundant system, this module can provide data of controller to data sever without loss. This paper presents three main features – separation of get task, usage of ring buffer and monitoring communication status –of CNet module to carry out these functions.}, journal = {International Journal of Computer and Information Engineering}, volume = {5}, number = {11}, year = {2011}, pages = {1481 - 1487}, ee = {https://publications.waset.org/pdf/7619}, url = {https://publications.waset.org/vol/59}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 59, 2011}, }
