介绍了基于PROFINET工业以太网技术的过程控制系统的组成,CPU315—2PN/DP作为PROFINET控制主站,从站由远程I/O(ET200M)和变频器MM440通过代理服务器IE/PBLINK连接到PROFINET网络中。系统的硬件组态和过程控制程序的编写用STEP7软件完成,系统监控功能和数据处理由WinCC软件实现。控制网络中有不同类型的数据传输,PROFINET工业以太网可以满足信息传输中不同层次的实时性要求。
The composition of a process control system based on PROFINET Industrial Ethernet technology is described. The CPU315-2PN / DP functions as a PROFINET control master and the slaves are connected to the PROFINET network via a proxy IE / PBLINK via remote I / O (ET200M) and frequency converter MM440 in. System hardware configuration and process control program written with STEP7 software to complete the system monitoring functions and data processing by the WinCC software. With different types of data transmission in the control network, PROFINET Industrial Ethernet can fulfill the real-time requirements of different levels of information transmission.
