能够监控、控制和模拟工业自动化过程的计算机控制系统必须提供足够的手段来处理时间、并发和分权。此外，控制系统还应该在维护期间运行，并且在故障安全行为期间也可用。在过去的控制系统中，随着趋势的改变，控制系统被集中到分布式控制系统中，因为现在的现实问题是分布式的，如通信、交通控制或建筑自动化等，因为实现应该是灵活的和可靠的。目前人们对新技术和体系结构越来越感兴趣，以便探索分布式控制系统的下一代技术。我们的项目是开发一个DCS系统，其中一个PLC作为一个主人，另一个可以作为一个奴隶。Master负责监视所有进程，这些进程连接到所有其他返回其状态的奴隶。MODBUS协议用于两个PLC之间的通信。我们已经使用LCD显示来查看被监控的数据。我们的主要目标是开发一个使用PLC网络的DCS系统，这对工业来说是经济的。
莫纳什代写作业:控制系统
The computer-based control systems, which can monitor, control and simulate industrial automation process must provide enough means to deal with time, concurrency, and decentralization. In addition, control systems should still function and be available during maintenance and also available during fail-safe behavior. In the past control systems are centralized nw as the trend changes Control systems are now moved from centralized to distributed control, because now real-world problems are distributed, as in telecommunication, traffic control or building automation, and because the implementation should be flexible and reliable. There is currently growing interest in new technologies and architectures for exploring the next generation technologies for distributed control systems. Our project was to develop a DCS system in which one PLC acts as a master and others would act as a slave. Master is responsible to monitor all the processes those are connected to all other slaves which return their status to master. MODBUS protocol is used for communication between two PLC's. We have used LCD display to view the monitored data. Our major objective was to develop a DCS system using a network of PLC's that would be economical for industry.
