摘要
海上采油平台原有的发电机组检测装置因其功能单一、且无法进入监控调度级的局域网等原因而需要升级。开发了一套基于OPC(OLE for Process Control)通讯的多控制器多客户机的网络监控系统,介绍了在C/S构架下MODBUS TCP/IP及OPC技术在系统中的通信原理和实现方法。以KEPServerEX作为OPC服务器,在机组检测装置与WinCC软件(OPC客户端)之间建立通信。并以安装KEPServerEX软件的工业控制计算机为C/S服务器,将各客户机和服务器相连接。MODBUS TCP/IP协议与OPC技术的应用,提高了通信的速度及系统的扩展性。
This paper designs a muIti-controI er and muIti-cIient network monitoring systembased based on the OPC communica-tions,and introduced the communication theory and reaIization of the MODBUS TCP / IP and OPC technoIogy under the C / S architecture.The system put the KEPServerEX as an OPC server,estabIished communication between the detection device series and the WinCC software (OPC cIient).IndustriaI controI computer instaI ing the KEPServerEX was used as the C / S server,due to the connection each cIients with the server.
