摘要
某大型装置中,能源模块为高能量设备,数量众多(近百台),需分组协调控制,对控制单元及通信网络的可靠性和实时性要求较高。基于实验平台进行了PROFINET CBA技术、OPC集成技术的应用研究,并以装置能源控制系统为例,设计了一套基于PROFINET的集群PLC网络通信工程方案,128KB数据包的响应时间小于1s,满足集群PLC实时控制需求。
In some great experiment equipment, there are hundreds of high power energy modules which need to be controlled on line. Control unit and network is requested to have high reliability and good real-time performance. The application research of PROFINET Component Based Automation(CBA) and OLE for Process Control(OPC) integration technology are studied on experiment flat. By the example of energy control system, the network control project for large-scale PLC based on PROFINET is designed. The response time for 128 KB data packet is less than 1 s, which meets the real-time control requirement for large-scale PLC.
